Mi 9 P2i Waterproof Internals? - Xiaomi Mi 9 Questions & Answers

Came across a Xiaomi Mi 9 teardown & was quite surprised when I read:
"This is the back of the motherboard of Xiaomi Mi 9, mainly distributed with some RF and power chips. Wang Teng said that this part of the chips has done P2i waterproof treatment. The publicly available data shows that P2i is coated with a layer of nano-polymer. This film is attached to the surface of the product. Even if liquid enters the device, it will not affect the components."
Is anyone able to verify whether this is true or not?, I couldn't find any other information on it..

Little update today, Xiaomi tweeted out a teardown including pictures & information about the phone and it's internals, looks like even without the IP certification they have went to some length to keep water out.

Outer Glass Repair Guide?

Dropped my Mi Mix (in case, on corner) and had a little luck in that only the outer glass cracked. Touchscreen and all of the normal phone functions still working, I'd just like to get this glass replaced as I see the parts are pretty cheap.
However...I can't find any guides for how to replace this piece of the phone. Found what was basically an entire Mi Mix strip down...except this 1 outer glass piece. ^.^
Any tips or can someone point me in the right direction?

Sorry to hear about this. There are no guides available as far as I know, except the few disassembly videos on YouTube which you may have already seen.
What case were you using by the way? And from what approximate height did you drop the phone?
You can buy the full LCD assembly here

Replacing the front glass without damaging the LCD will be very tricky.
I myself have a chipped corner, however I would get the assembly before attempting a glass replacement.
Here is an even cheaper one

Anyone have experience replacing the outer glass? Not just if i want to drop $120+ to replace the whole LCD screen at this moment.

Think best idea would be to replace the lot, they never split good and watch takedown video 10 X before you attempt it.

I also dropped my mi mix 3 and I saw a outer glass screen for only $4.00 and talked to my friend phone technician to help me replace it for around $25.00 for the fee or labor. I'll give out my review about the performance after the replacement

Any feedback or follow up on this?
Same dilemma, not trying to replace the entire screen - just the glass.
It'd be nice to pick up the glass and find someone to do the repairs instead.
I busted my screen on my mi mix and bezel. I am looking for a technician professional to fix my device is there any place online that can do this? I searched but couldn't find anything. I would do it myself but I'm afraid I'll fail. I just need the bezel and glass changed.
NEW Mi Mix
I bought my Mi Mix about 3 years ago. I really love this phone, but just last month, the glass started separating from the frame, my flash doesn't work and about 2 years ago, I got a small chip in the glass on the top right corner. I take superlative care of my phones, so don't know why I started having these issues. I started looking for another one to replace it and wasn't having any luck. Then, I came across this link on DH Gate. I first was rather skeptical, but ordered it anyway. The seller had it listed for $192.
I charged it with a credit card so I could always dispute it later if it turned out to be a hoax. I chose expedited shipping and sure enough, the seller sent it with Fed-Ex and it was delivered to me in 3 days from China to Texas. It was only the phone. Didn't have any accessories, except a clear TPU case. No original box, but I didn't care about that.
It was a fine transaction and I'm happy with the phone. It had some strange developer ROM on it that I re-flashed with another ROM with TRWP. The TWRP versions for lithium did not work, but I found a TWRP version by mrraines that works.
The only problem with it is that the theme and mi store are in Chinese. No matter what I do, I cannot get them to display in English. I've flashed it several times and I got the closest version that I could find that was close to the original Marshmallow ROM on my original. It's working great, though and I did root it, just flashed SUPER SU with TWRP. You have to use the MI unlock tool, but I didn't have to wait and the unlock procedure worked immediately. Anyway, in case you want to order a new one, here is the link for the one that I ordered. I can verify that the one that I got was BRAND NEW, not refurbished or used. Absolutely perfect, no scratches or marks on it. I looked it over with a magnifying glass and found no marks of use.
https://www.dhgate.com/product/orig...5199967.html?skuid=563545286555742208#seo=WAP
Pay the extra $20 and use the expedited shipping and you'll have the phone in several days.
Cheers,
Frank

Thank you for the link i appreciate it! The crack on my mix isnt very bad but it does annoy the hell outa me lol. That crack is the only thing thats wrong with my device, theres no screen burn or any other issues just a crack across my screen and the bezel is damaged slightly from the impact. When i get another device ill probably get the OnePlus 7 pro the reason is because the front camera is hidden i very rarely use a camera. I dont need a front camera and i really like how OnePlus designed a device with a hidden front camera.
You might also consider the Xiaomi Mi9T. I bought a Mi9 off of facebook marketplace from a lady who bought it but never used it. Then they came out with the Redmi K20, which is only for Asian countries. Then they released the Mi9T.
I bought it mostly for the beatiful back. I got the red one. It has a pop-up camera. No bloatware on it.
I bought mine from Banggood.com, but Amazon also has them. I don't know what country you're in, but I'm in Texas, USA.
NO NOTCH!! I have several phones with notches, and hate them. I have 45 phones and my latest is the Galaxy Note 10+.
So I now have 4 Xiaomi phones and love them. I use Mint Mobile, which runs off of T-mobile towers and the data speeds are fantastic where I live. They also came out with the Mi9T PRO, which has the cooling system.

The Galaxy S9 Is IP68 Water-Resistant — Here's What That Really Means

The day has finally arrived — Samsung has unveiled the Galaxy S9 and S9+. Apart from minor upgrades, the two might not appear to be much different from last year's S8 and S8+, but that's not necessarily a bad thing. One feature that hasn't changed is the Galaxy's IP68 water-resistance rating. That's a great score, but it begs the question — what does that number really mean?
First of all, if you don't know what the IEC 60529 is, don't worry — it's a standard put out by the National Electrical Manufacturers Association, which is basically a test with set rules and regulations. A device is then assigned an IP rating for resistance to dust and water in accordance to its performance on the test. To quote the standard itself:
— National Electrical Manufacturers Association said:
This standard describes a system for classifying the degrees of protection provided by enclosures of electrical equipment for two conditions: 1) the protection of persons against access to hazardous parts and protection of equipment against the ingress of solid foreign objects and 2) the ingress of water. The degree of protection against these two conditions is designated by an IP Code.
Click to expand...
Click to collapse
While "IP Code" really stands for "International Protection Marking," most nowadays refer to it as "Ingress Protection." All that really means is how well protected a device is against dust and water.
Speaking of dust and water, those elements are not weighed together into one grade. In fact, the number assigned to a device — the one that appears after the "IP" prefix — are two individual ratings. The first number denotes how "dust-proof" the device is, or how well the device protects against dust and solid particles, while the second reflects its "waterproofing," or how well the device keeps water from entering and damaging the sensitive electronic parts inside.
Samsung's latest Galaxy devices both earned themselves a rating of IP68 in the IEC 60529 tests. While a very high score — higher than the 2017 line of iPhones' IP67 — these phones are not waterproof, just water resistant.
IP: The abbreviation of "Ingress Protection," the rating system for a device's dust- and water-resistance.
6: An IP rating's first number represents a device's dust protection rating. A "6," although smaller than the S9's second IP number, actually means the device is completely dustproof. Good on you, Samsung!
8: Water resistance is denoted by the second number of the rating. An "8" shows that the S9 devices can be fully submerged in water as deep as 1.5 meters for up to 30 minutes. For reference, the iPhone X, which scored a "7," can be submerged for 30 minutes at 1 meter deep.
So, what does this mean for you? If you accidentally drop your new phone in your toilet, get caught in the rain, or spill a tasty beverage on it, you shouldn't panic. However, you shouldn't push your luck — going swimming with an IP68-certified device isn't foolproof, and the chemicals you find in a swimming pool or the saltwater of the ocean might not mix well with your S9. Our advice? So just be careful.
You see, while the IP Rating claims a certain level of protection against water and dust, it doesn't take in account chemicals or particles that you might find dissolved in water. Saltwater and chlorine can hurt the finish of your S9, and even damage the rubber protection that gives your phone its IP68 rating. While it's certainly tempting, we'd recommend you not plunge underwater with your phone in-hand. It might be fine, but if it's not, you could be on your own.

While it's certainly tempting, we'd recommend you not plunge underwater with your phone in-hand. It might be fine, but if it's not, you could be on your own.
It all comes down to your warranty coverage. While we don't know yet about the S9's policy, with the S8, Samsung includes a limited warranty that covers manufacturer defects for one year, battery issues for six months, among other things. However, soak your S8 to the point of damage? You've voided your warranty.
That changes if you opt-in to Samsung Premium Care, a monthly-subscription coverage that extends the boundaries of your warranty by leaps and bounds. If you take your S8 for a swim, the device will be completely covered, even if the components inside fry before you dry. You get up to three cases of accidental damage per 12 month period, though, so the fourth time you lose your Galaxy at the bottom of the pool, it's like you never had coverage to begin with.
In short, what you've heard about the S9 is mostly true — the phone stands up well against the elements. While spills, grime, and accidental submerges shouldn't be cause for concern, we'd still warn against diving deep with your S9. It doesn't matter if the phone is IP68 or IP67 — if water touches the wrong parts, you could be in trouble.
Quick question related to that. Can I take it in the shower or something?

Here's Samsung's official word on their IP68 rating and the Galaxy devices: http://www.samsung.com/au/pdf/IP68.pdf
Personally I won't ever put my device under any water at all. Sure, it's water resistant, but if you ever drop, or bump your device, that could be enough to put a TINY little micro leak in the water seal, allowing water into the device. And if that happens, bye bye device, bye bye warranty.
I've never understood people who take their phone into the shower to be honest.

Xiaomi Mi Mix 3 5G Unboxing & First Look

Fellow members I have just recieved the new Xiaomi Mi Mix 3 5G so I thought I would share my unboxing and first look with you, Here is the Link if you want to watch my video: Mod Edit: Link Removed
Any questions feel free to ask, If you prefer feel free to read my thoughts below:
I will be unboxing the brand new Xiaomi Mi Mix 3 which has a secret, yep that’s right it’s the 5g version! I have been waiting for this this device for sometime and its finally available from Vodafone.
The box is classic Xiaomi in a black and gold look which obviously symbolises this is a premium luxurious product. Opening the box there is a nice message from the CEO of Xiaomi, Lei Jun.
Removing the card reveals the show stopper the Xiaomi Mi Mix 3 5g, I have the Onyx black 6gb RAM 128GB storage model. Also included in the box is the USB C charging cable, the Xiaomi fast charger, a headphone dongle, a slim case which is a nice addition and of course the usual booklets which no one reads.
Taking a look at the Mi Mix 3 5G, the first thing you notice is the beautiful 6.39in amoled full screen display which is totally uninterrupted, no notch, no punch hole and I feel this is my favourite solution out right now as the 24mp selfie camera is hidden behind the screen on a slider mechanism which is not motorised. I can’t explain how satisfying it feels to slide it open and closed. Whilst the phone is locked sliding the screen down allows fast face unlocking but if the phone is already in usage then it will launch the selfie camera.
On the top of the device there is a microphone, on the right side the volume rocker and power button, at the bottom, there are 2 grills one which houses a speaker and the other the mic, nestled in the middle is the USB C charging port. On the left is a key for the google assistant. Around the back it is just as beautiful as the front, a curved premium ceramic back which makes the Mi Mix 3 feel very dense, weighty & premium which is part of the reason it weighs in at 225g. The top left corner has a tiny camera bump which houses 2 12mp cameras, one is wide and the other telephoto with the flash sandwiched between them. The fingerprint sensor is also housed on the back and is extremely fast, I personally feel the positioning is spot on. Of course it wouldn’t be complete without the 5G logo & Mix branding in a beautiful gold finish, Did I say premium? It doesn’t get much better than this.
Now I know this looks very familiar to some of you especially those that bought the original Mi Mix 3 but Xiaomi has improved this version in 3 ways, firstly with the addition of 5G and secondly the latest Snapdragon chipset the 855 now replaces the older 845 and thirdly a bigger battery going from 3200mah to a much bigger 3800mah which are all welcome additions. It looks like Xiaomi went with the if it ain’t broke don’t fix it philosophy and to be honest I am glad. The Mi Mix 3 feels ergonomically perfect for me, not too big and thick enough where I can hold it comfortably in one hand and this is where the curved back feels wonderful.
I am also extremely pleased that the screen is flat and Xiaomi didn’t go with the current trend of curved screens because there is no issues with image distortion or colour warping making it very easy to view. It is still a 1080p resolution with a 403ppi and this definitely will aid with battery life.
The Earpiece unfortunately doesn’t double as a secondary speaker which I would have liked but it’s not a deal breaker as the bottom single speaker seems to be a good quality one. Also missing is a 3.5 mm headphone jack which most OEMs are adopting, unfortunate but sooner or later everyone will have to board the Dongle and Bluetooth bus.
Overall so far I would say anyone in the market looking for a 5g handset should definitely consider the Xiaomi Mi Mix 3, I have personally owned and still have the Xiaomi Mi Mix, Mi Mix 2, Mi Mix 2s and now the Mi Mix 3 5g which is the pinnacle of this series of phone. I can testify the longevity of the Mi Mix range and it’s clear that Xiaomi have refined the mi mix into what you see here.

Mate 20 Pro as the other curved screen glass replacement

Hello folks
Gathering information about screen replacement.
It applies for most curved OLED screens.

etc.
Including reputable screen refurbish services, only glass replacement services and part sellers or sources.
There can be found several ways to separate only glass from screen.
Old style heating and cutting glue layer with wire/other tool.
Or freezing to very low temperatures (somewhat -150C) and can separate easily afterwards.
Would be nice to hear your experience in such subject.​
Laser is also a possibility, check this out : https://youtu.be/Lj4Od9D4puc

Ahh yes Daniehabazin and the lasers
Although it can be used to cut out back glass or around the screen.
Just haven't seen successful screen glass separation using such method. It can be quite challenging.
Is there any repair guys in your knowledge who does already mentioned jobs in Stockholm?

Question Please help with my second hand device.

I recently bought mi 11 ultra from a local seller who claim it just 10 days used, with genuine invoice.
But I think this piece is having slight gap on back panel, maybe be it is open for some repairs?

As You can see in image I can easily slide small piece of thin paper inside it. I am worried that it is open and will not be water resistant anymore. Can someone verify?

First try online Xiaomi customer support service. Ask them if your phone has repair records.
If there is repair records, you can bring the phone to Xiaomi repair center and request them to deal with the gap you are concerned about. They check the warranty validity and if valid, will repair it.
If there is no repair records from Xiaomi, complain to the local seller you bought from. Tell that seller to fix it, or simply request refund. Warranty from Xiaomi is at doubt in this case.
Sketchy seller will avoid responsibilities by saying that gap is caused by you. Even if you did not cause it, you have no proof.
This is a lesson to learn when buying 2nd hand stuff, you have to check everything right in front of them and better make a video while checking and unboxing at the point.
