My Galaxy M21 phone's AMOLED screen got damaged due to liquid penetrating a few days ago. I went to the repair shop and asked to replace the screen with LCD one.
After replacement, everything is working fine, except for the proximity sensor. It always reports far proximity even if I bring a surface completely covering the screen. During calls, the screen does not automatically turn off when bringing it to my ear.
I have asked the repair person, and he replied that the LCD screen does not have holes to accommodate the sensor properly, so it is blocking the sensor. But AFAIK if that's the case, the sensor should always report near value, not far.
Is there any solution for this or is this a known problem due to LCD screen replacement?
Welcome to XDA
Not really if the mobo doesn't support the alien hardware.
The firmware instruction set may able to be altered to get the new hardware to work as you want.
It been better to use the original display, but not doing so you opened a can of worms.
Water damage? Possibility of mobo damage as well particularly if the battery wasn't quickly disconnected. If it was salt or brine water it's already dead.

By water damage, I meant a small amount of water somehow got into the screen and darkened the screen slowly starting from one side (a common thing on AMOLED displays).
I can assure that the water didn't cause any problem other than the screen, because I regularly check the device stats & sensors. The proximity sensor is behaving like this after screen replacement.
Well the former of what I said then applies.
I'm surprised it will even function with an LCD.

Sorry to barge in friend,
Thats why I am very careful with 3rd party repair vendors, I have lost many phones to them, they REPLACE new hardware with old spare components,its a bad habit they have & thats why the OEMs have "Authorized Service Centers" exactly for this reason.
For Shamshung devices I suggest you go to Shamshung Authorized Service Center only as Shamshung parts are quite in demand because of good build quality.
Small Story: Few days ago I went to Shamsung Service Center to try to downgrade my M21 from A13 to A11 (my phone is within warranty) & as expected they told me "only upgradable not downgradable sir!". I knew they were lying because a friendly shamshung service center guy once told me they do everything there internally, they have repair softwares there. Anyway, so I took the phone to a 3rd party repair station and the owner named Salman told me he has downgraded so many Shamshung phones of newer models, all I have to do is leave the phone with him for about 10 hours & he will downgrade from A13 to A12.5 then to A12 then to A11.5 and finally to A11 so it will take time, NO! he was lying! He was charging me a biggish amount but not just that he needed 10 hours to fix the mess that would happen when he stole & replaced the new components with older ones. Thats why Authorized Service Centers only friend.
@OldNoobOne I already went to Samsung's authorized service centre, but they only can replace the screen with AMOLED.
I was desperately trying to avoid AMOLED screens this time because they get damaged easily and are more fragile than LCDs (that's my experience with them).
Don't know how much correct I am, but I have seen most AMOLED screens getting damaged completely due to the slightest of shock or due to a single drop of water somehow seeping into it. I have never seen this type of problem with LCD screens.
Looks like I should have bought a phone with an LCD screen in the first place.

Yes friend, not just that LCD screen phones tend to consume lesser battery too. Another way to avoid AMOLED issue is that is to use a plastic pouch during rains etc. (there is no problem in communications) or also use a flip-cover instead of normal plastic/rubber back covers only. Just use a good quality scratch/screen guard like 3D+ and LCD will look quite like AMOLED

All phones should be kept dry regardless of the IP rating. As you found out the AMOLED diodes used in displays are water soluble. The displays are sealed but if the seal is breached by water they will be destroyed in short order. Always use a good case to protect from impacts and high G loading induced damage when dropped. Wipe all water off immediately.
This N10+ in my has always been in a good case and unfortunately has been dropped onto concrete many times (zero visible damage). It has well over 8k hours on it. The display shows no sign of damage or degradation whatsoever. Don't use in direct sunlight and use manual brightness keeping the brightness at 50% preferably less it will get many years of service.

AMOLED displays use -less- battery, have infinite contrast (pure black) and the best color gamut. Higher and variable refresh rates are also possible, but these tend to use more power.
They are more expensive and have shorter, finite lifespans. Other than lifespan they are superior to backlight LCDs. That's assuming you protect the phone from drops and the design/QC was good when manufactured. Of course display quality can vary from manufacturer, model and individual displays. It could be you got a defective AMOLED display from the get go. Samsung's QC has been slipping in recent years it seems. A used N10+ in good condition might have been a better choice than a new midrange Samsung. It remains one of the best phones Samsung ever produced.
LCD displays are easier and cheaper to manufacture so you pay more for AMOLEDs.
If you prefer LCD displays by all means use them.
They are more rugged but not bulletproof by any means.
(Always protect LCDs from solvent exposure like isopropyl alcohol; they are open vented to the atmosphere and solvents can poison/destroy them.)

This question is directed to those who have taken apart their Kaiser, and specifically screen the screen assembly. I've got water issues and the screen is broke now. Here's the story. I might get some outrageous warranty charges.
I installed the InvisiShield (www.shieldzone.com) on my phone. Essentially it's a screen protector that is indestructible. It practically is, but unfortunately it destroyed my phone. To install it you have to spray this liquid on the back of the 'shield' and apply it to your phone, using a squeegee to get the bubbles out. It went pretty well, and I was happy with the results, but 3 days later my screen stopped working.
Everything is washed out, and it looks like water got inside the LCD somehow. For instance, colors streak across the LCD in fonts, etc.
I called ATT and they are mailing a replacement, and I'll be expected to send this phone back. They said if the return phone has damage that would void warranty (water damage, etc) I'll be prorated $400 on my next bill.
Over the phone the customer representative had me remove the battery and check one of the water damage pads to make sure it was white. It is.
For those who have seen internal phone assembly, is there any of these directly by the screen that will pick up moisture?
As far as ATT knows, the phone LCD suddenly stopped working. I'll get a replacement and /hopefully/ theres not a moisture pad right next to the LCD assembly. Anyone know?
Damn, hate those broken screen story's. Scars the **** out of me.

I dont know but man I hope that there isn't. Have you tried contacting invisishield? Never mind, b/c they'll blame you. Most applicators like that use alcohol to evaporate the remaining moisture that's left. My friend applied it to his, and he used very little liquid(scared), so GOOD LUCK!! I MEAN IT
Tough break, sounds dangerous to pour liquid on the screen though !
On a related matter has anyone seen pics of a Kaiser pulled apart ? Still wondering where the GPS antenna is located !
Yeah, I hope I don't get shafted.
I love the invisibleshield, and I put one on my $1,500 DSLR camera screen, but since the Kaiser screen is recessed a bit, when you squeegee the solution out from under the screen, it cannot be wiped away. It just gets pushed out between the phone's body bezel, and the screen glass -- right in to the phone. With my DSLR camera, the screen is flush with the body, so when squeegee'd I could quickly wipe the water/alcohol away.
Contacting Invisibleshield got me:
Our liability does not extend beyond our product. The lifetime warranty only covers the replacement of the invisibleSHIELD and NOT a warranty for the device the shield is protecting.

If ATT charges me the $400 if they find out, I guess I'll pay it. It's my fault, but by extension of invisibleshield. Guess I'll learn not to use that product on anything that has a recessed screen. I was thinking of buying an invisible shield for my laptop as well, but it's screen is slightly recessed like the kaiser, so you can forget me doing that!

That was why I bought the 'best screen shield on the market' for scratches (invisibleshield). Coincidentally that was the demise of my phone. I also purchased a steel case that basically would let me sit on my phone (uncomfortably) if i wanted. The desire to protect my phone, did the opposite in my case.
Wow what a horror story. Thanks for sharing with us - may prevent another phone from dying.
Wondering if you remove the battery and not using for a few days until the water dries out before turning it on?

Could be, zcink. The replacement phone is on it's way. I can remove the battery during this time it takes for the replacement to come and see what happens. Unfortunately, I think one of the following has happened:
1) Water seeped between the LCD protetcive glass, and the LCD itself, and somehow soaked in to the LCD causing mini shorts -- thus resulting in kludged text.
2) Water seeped to the phone's connecting cable where the screen input is, dried on the wires, thus creating a short -- destroying the signal.
Either way, when the liquid dry's, the mineral deposits causing the short will still exist, still causing a short. For both, repair requires disassembly, voiding my warranty. I could buy a new replacement screen from the China place for about $100, but if ATT /might/ replace it without screwing me, I'll take the chance. Just wanted to know what my chances /were/ them finding out it's got water in it.
I guess the moral is.
Don't buy from InvisibleShield, unless you use a SPARING amount of spray they they include. They include a huge bottle, and I used 2 sprays worth applied to my shield. This created enough excess to be squeegeed right into my phones body. The phone worked great for a few days, until one day at work, while I was using it -- BAM -- the screen was dead.
There isn't the water dectector there, but I'm pretty sure the technicians would notice the damaged screen.
I know those screen protectors, used them for alot of things. Using one right now actully. Its the one you wash with soap and warm water, and just let it dry, it have a static adhesive to the the scree.
I see. yeah hopefully the ATT tech will be lazy and just grant you the warranty without investigating. just play dumb. If they charge you the $400 call them up and threaten to switch to T-Mobile.
My phone died and T-Mobile was going to do nothing until I threatened to switch to ATT, then they replaced it.
I seriously doubt that they will be able to tell unless you really soaked it, next time use a dry screen protector, they work just fine, no bubbles. The only moisture sensor is on the battery, and if it was a tiny amount of moisture, there's likely no signs in the screen assembly. AT&T isn't likely going to dissect the screen to check.
Kaiser disassembly howto
I have found this one somewhere here, can't remember where... Hope this helps.

Hadn't heard of that screen protector before, guess it would work well on an HTC Touch, not sure how the "full body" version works though!

Amazing find. Thanks!
It appears to me that the screen itself is it's own modular unit. Meaning, after phone disassembly, you'd have to disassemble the actual screen itself. Further, there is no moisture indicators directly by the assembly it seems.
Knock on wood, but I'd hope a tech wouldn't go that far to determine the fault of the phone. I assume they would if theres telltale signs of water damage to the display (streaking might be a common sign.) But, maybe, just maybe, they won't.

The service manual shows 4 of them, one under the battery that can be seen from the outside, one at the top and one at the bottom of the mainboard's other side, and.. one on the board that holds the bottom front panel switches, so very close to the LCD.
Personally I wouldn't have asked for a replacement phone, I'd have disassembled the phone and tried to clean it if made dirty by the liquid, bought a spare screen off ebay if it was definitely dead, and if ultimately it didn't work bought another phone off ebay for less than $400. But maybe I like risk

Keyboard membrane removal.
So, I've had trouble with my keyboard lately and wanted to just clean off the contacts on the membrane...but I can't seem to get the damned thing out of the plastic keyboard Middle Housing.
I have gotten everything apart so the housing is separated. Verified that I did it the way the service manual says...but i saw NOTHING about how to disassemble the keyboard from the housing.

hello guys,
my tytn II cant detect simcard saying the simcard is missing.
Any idea whats wrong???
I have read lots of threads and comments on the Internet regarding screen cracking on the z3c but most are dating back to early 2015.
As I am now considering buying a Z3C does anyone know if improvements have been made by Sony to address these issues for the 2016 models?
Thanks for any comments.
Nothing has changed. On the bright side, replacing said-glass is very cheap and easy to do. On the minus-side. Say bye-bye to any form of water-resistance. This long with the Z3C: I've grown to accept this phone won't be water-resistant unless I use a case because the seals and IP-68 rating is only for fresh-water and the rating completely depends on the ability of flap-seals and sealant of the back cover to to do its job. I hope I can convince you to disregard water-resistance factor in your purchase. Notably because Sony won't cover any repairs if the damage is a result of water-damage(personal experience). That way, you can swap back glass covers as you please. They go for like $2.
My z3c screens right top corner today unglued. Lasted for about 8 months since purchase, without case, without any water interference. Still under warranty, sending it for repair.

Thanks for the reply, if I understand you correctly replacing the back glass is not a big issue and is cheap, but what about the front screen? I did have a quick search around the net and it looks quite complicated and expensive to replace the front one.

I service my own phones often enough to kind of say that replacing your own front screen is easy to do if you're starting out with this phoneYou take out the front-screen the same way you take apart the back screen.. As long as your motherboard components are in good condition like the USB Port, antenna, SIM/MicroSD slots, and the battery(cause this is glued very well to the motheboard), nearly everything on the Z3 Compact is expendable and easily replaceable.

I've been using Z3C (15W33) since early september and this phone has really rough life. I mean working in very hard conditions (very cold outside > pretty warm inside the house) and I never really cared about it even when I know there are problems with the glass. Also I have a custom s-line case and that's the only protection... I dropped the phone twice or three times...
but it's still running pretty nice and there are no signs of any damage, the glass is more than OK
I just purchased one of these off Swappa for 60 bucks. I got too excited, I couldn't control myself, haha. The glass is cracked, and I'm contemplating trying to remedy that depending on potential usability. I remember sometime late last year that there were a whole bunch of displays for the prototype with the "Not for resale; property of Motorola" sold off on eBay; they're long gone by now since people bought them up thinking they'd work on the standard Nexus. But they discovered the display connectors are in slightly different places than their production unit; meaning they're not interchangeable and couldn't be used. If I can't find one of these displays, I'm expecting that I could just remove the glass and replace it with a standard one, but I'm HORRIFIED of potentially damaging the display itself since they're so fragile. It's horrifying because if it's damanged, that's it. It won't accept a production panel.
So I guess what I'm wanting to know is if anybody happens to know where I can get a hold of a replacement display for this phone at a decent price. As mentioned, the display works fine, but the glass is cracked. I'm not expecting to be able to use it since these phones seem to be finicky, so I'm not interested in dumping any huge amount of money into it; I'm just exploring my options on restoring it. If I can happen to use it for personal use, that'd be great; but i'm not holding my breath haha.
Slightly OT, but if you have a prototype model, I wonder if it also has the internal connector for the fingerprint reader. That would be interesting to find out.
Screens pls, btw i found 1 long time ago in eBay, Google buy then back for mich money

i use these over screen protectors. the are big enough to fit phone screens and do a nice job with glare from light while keeping the display to color. they scuff up (like all do) but the......gel? like texture will smooth back out instead of removing the visibility. there are 2 draw backs....they add a soft prism texture due to the quality on the glue involved as well as soft dots from the high quality adherence. the more it warms the softer the dots appear. all said and done, i have put this laminate on cracked screens with a fair solution. no shelling out for the lcd as well as not risking a lcd for a $25 dollar piece of glass

I definitely appreciate the suggestion, but I'm specifically looking for input on where I can get replacement screens. I don't mind cracks in screens personally (swappa boneyard represeeeeent! lolol), but with my last N6 screen cracking from compromised glass up top, I'm paranoid of any use doing the same to the prototype display. I want to either use it or sell it, and as long as the glass is broken I can't really do either :crying:
Finding a prototype display is going to be virtually impossible due to ridiculously limited quantities, and replacing it with a production model version - if that's even doable - would kill any value the prototype might still have. If you're looking to use it, you're probably going to have to fish for a production screen and hope Motorola didn't make any changes between the prototype and production model.

Then, do it have it or not ??
If the touchscreen isn't broken, you can change the gorilla glass only, by yourself. It must be standart size. (using heatgun and being tricky)
If it is, you can go to Shenzen in China, or maybe try to adapt the connector (they might have taken the same components but in a small different way, connector lenght/position)

I replied you and him only to tell that it's really hard , only to let you know and to let him know before he tries to order the glass,try to separate that from display and make it worse . Oled displays goes completely black if broken ,instead of LCD that stay alive .
I know procuring one is next to impossible. The reason I asked is because I had seen a large batch of them sold on eBay sometime last year. So people expecting them to work for their regular Nexus phones (they don't; ribbons are slightly different) bought them and ended up not being able to use them. A shot in the dark for sure, haha. Otherwise I have replacement production glass, LOCA, and a plate and wire to do the job properly, it's just as all stated in the original post: failure is an absolute game over. A screen with cracked glass is much more functional than a dead screen with good glass, you know?
Hi to all users is this note 8 a worth buy for 260€? Im not planning to replace the display with a new one will the current display be ok for next months or will go black just like nothing at some point? Thanks for answers..

Sometimes if i put the birghtness on low the low part of the display where is broken sometime just flashs some times if this is not enough i will put a video to show you better..
The price maybe sounds not bad, but if the display already showing issues,.... forget it. the Display problem can not get better, just worse.
And consider, with this damage it isn't resistant against water. Not even against humidity.
and a possible glass repair makes it much more expensive.
My opinion?
keep away from it !
Don't be afraid to hit the "Thanks" button if someone helped you. It don't hurts
So! Little update i find when and only the phone shows up the green screen on display like in the last picture (in the first post) if i lock the phone with always on activated and then i press the button to wake up the phone the green screen shows up! But for example if after that with still green screen on display i lock the phone again but i dont give him time to show the always on and i press fast the wake up button the display bring back normal! This mean that with always on display always off i can lock and wake up tue phone all the time without the green screen issue... Why it does this?
Buy it for €220

Look up sammy green screen of death. S7 had that issue. Yours is probably from dropping damage. Needs new display.
Seeing as it is already damaged. It will probably need repairing to make it a functional for the long run. That said after ir has been repaired it will no longer be water resistant.
Thanks for the answers i really appreciate i take the decision not to risk i think is better take out from the pocket something like 500/550€ for a used one in optimal condition and not to spend 250€ for this and then spend again 250€ for the display replacemant

Who says it wont be water ressistant?! My friend's s7 edge was opened and repaired in OFFICIAL store and it was used in water after that...

That is a different story. As 3rd Party repair shops won't be able to guarantee that your device will be water resistant once it has been opened up and repaired. As the double sided adhesive used by Samsung is not used by other 3rd Party Device Repair Specialists.
Dont take it to 3rd party then... logic
I posted this in the official Samsung forum but I get the feeling that nobody there has ever been inside a phone. Hopefully get better feedback here!
Going to provide a rundown of the phones history..
The screen started to go slightly green randomly about a year ago. But I noticed that turning the screen off and on again fixed it.
This issue became more and more frequent as time went on during a few months use.
Then it transitioned over to a permanent problem, with no amount of reboots or whatever to make a difference.
Then horizontal lines started to appear which would travel up and down the screen leaving the picture black in some parts.
Then I noticed another thing, turning the screens brightness down to about 20% removed the lines, and made the phone usable again (albeit still with a green tinge).
I thought that it must be a power issue rather than a screen issue, so changed the battery but sadly that didn't have any effect.
More months go by, and that 20% threshold got shorter and shorter until I had to keep it at around 10% brightness to get a full screen picture.
And now finally the phone seems to have died. It doesn't turn on anymore and there is no vibration so its definitely not just the screen being off.
FYI I couldn't see any signs of moisture and the moisture sticker hasn't tripped. But I still haven't ruled that out. I will examine further after getting some feedback..
I have of course tried all of the obvious like factory reset, clear cache partition and all that.
Before I open it up again I would like to know what people think?
Cheers!
Is the battery good? If the battery was really degraded though normally it wouldn't boot.
I wouldn't throw too much money at it especially when you can get a used N10+ for around $350 now. A substantial performance upgrade.

Hi thanks for your reply!
Yes I have swapped out the battery for a new one. The way it deteriorated felt like moisture corrosion but didn't see any signs of moisture inside when I looked. It could be deeper underneath the mainboard though as all I did was replace the battery so didn't see further than that.
Yeah I won't put much money into it, but I do have a decent understanding of electronics so I was hoping there would be a fix which I am able to do at home with basic tools to hand. Many things can be fixed with a reflow and individual pieces are cheaper to replace than say an entire mainboard. But I have no knowledge on this sort of problem so I'll wait to see if anyone else has and then open it up again and take pics of what I find.
Cheers!

Inspect the ribbon cable contacts for corrosion if you suspect moisture damage. Without a factory test jig finding say a solder fracture on a BGA chipset will be a lot harder. That's also another place corrosion from moisture damage can hide.
Generally with moisture corrosion damage will be evident on the buses and power supply section of the board.
If water damage is present the mobo is pretty much doomed because of the latent corrosion process. Water will also damage the AMOLED display pixels themselves if they're exposed.

Thanks for that. I suspect the screen escaped damage based on how it looked. All pixels were fine but those horizontal black lines would travel up and down so feels like maybe the controller or ribbon as you say because it felt like the screen was getting less and less power as time went by forcing me to keep lowering the brightness so that makes sense. Although it doesn't explain why it doesn't switch on anymore. Unless the phone is built not to switch on if the screen is disconnected?
cheers

Make sure the power button and contacts are good. Since AMOLED displays have an active matrix it could be that or the mobo.
Maybe someone recognizes those syptoms... thankfully I never experienced them.

Thanks for your attention and advice!
Sorry for the delay. I have had it back open and inspected every part closely for moisture damage. Couldn't see any signs but while I was there I changed the battery which sure enough fixed the power issue.
Strangely, the screen worked 10x better for about an hour after reassembly! Then it started to go back to the usual black lines engulfing most of it at the mid-range brightness level but not at low or high brightness which I find very odd. Last time I'm sure it did it at any brightness level over around 15-20%
Anyway better to just let you see for yourself. I have taken some videos and photos.
At this point I'm thinking it has to he solely the screen thats faulty as if it was any sort of power issue then it wouldn't behave this way..
This video was taken straight after reassembly.

The other was taken a few days later.

You're welcome. Did you inspect the display ribbon cable contacts? Someone who repairs these could probably tell by that vid. Probably the display, but I would try to verify that before you throw money at it. For $350-450 you could get a used N10+, a huge upgrade but no 3.5mm jack. Samsung leaves more off every year, too bad the price doesn't go down too. schmucks.
