New unboxed redmi 4x speaker faulty - Xiaomi Redmi 4X Questions & Answers

Hi all,
Just received a brand new redmi 4x from HongKong and the main speaker isn't working.
I've tested it using the inbuilt tester (settings,about phone, multile tap on Kernel, single test, speaker) not a whisper from it so I'm 99% sure it's faulty hardware.
I'm not sure if I can be bothered to wait for sending it back to HongKong for a replacement and they don't have an international warranted (as far as I know?)
Probably I will order a new speaker unit and change it myself.
Anyone have any inputs on this?
Look a fairly easy disassembly according to Youtube videos. Anyone have any experience to share?

why no warrenty?

Warrenty there is, but i ordered the phone from Hong kong and the lead time for returning, and recieving a replacement is gonna be nearly two months.

Faulty Build of Diamond2 earpiece?

I have two Diamond2: 1st one has no sound in earpiece in July and the 2nd one has the same symptom now. The sound can be heard in speaker and bluetooth headset, but no sound route through the earpiece. Hard reset or reflashing the ROM did not recover the issue. I have seen other posts in different forum claimed similar issue. This makes me believe that there is Diamond2 earpiece build quality. Picking both Diamond2 to HTC and they just change the earpiece but did not comment about the possible cause of this issue.
Just wonder how many users have the same issue and need repair from HTC?

Yes, I have seen your mentioned post before I post this thread. My thread is mainly concerned about the build quality of Diamond2 earpiece seems below standard. I have also read your reply that Vietnam HTC service centre even acknowledged this is common issue of Diamond2 that I am unwilling to accept.
Maybe this problem is limited to just few of us.
I hope so. But I have 2 Diamond2 and both have to replace the earpiece. This is not a single device but 2 have the same issue. This makes me doubt about the build of Diamond2. I have seen in PPCSG website there are users having the same issue in earpiece.

Just hope it is only some lots have this issue, but not the build quality.
Diamond2 Bad Ear Speaker Quality
I have the same issue with my phone
The bigger issue to me is that I live in Costa Rica, so no way to get HTC support
I am trying to find the ear speaker to buy it online but can't find it
Does anybody knows where I can purchase it?
I'll really appreciate any help
btw, I am really disappointed with HTC, they have a lot of time in the market and experience to have this type of quality issues in new phones
I am also very disappointed HTC about the Diamond2 build quality.
Here is another thread that 2 posters (at moment of this reply) have the issue of broken earpiece.
http://forum.xda-developers.com/showthread.php?t=547235
I would expect more and more Diamond2 users will have this issue. It is the fact that Diamond2 earpiece build quality is below standard. As my starting post mentioned, my two Diamond2 ran into broken earpiece in different time. Time will prove. I am going to sell my both Diamond2 to other phone. Good luck to all of you.
yep min doesn't also work no more ..
another problem which i have is that sometimes the upper part of the screen does not work anymore?
Sounds like a select few are getting a bad batch or something.... A lot of people have had no problems at all, but some do.... hTc cannot be perfect. If you contact them by phone or email, I'm sure they will be glad to help.
did you use the wired hands-free that came with it?
this is probably caused by the bad usb connector
damn is sent the device to euro twice for the broken ear peace with the hard spl from xda and now the wont repaire it. Have to pay 400€ for a new mobo.
I still have the original rom..
Diamond 2 No Sound
It just happened to my Diamond2 yesterday. Still cannot get it fixed. Really appreciate if somebody or someone or even HTC itself could fix the issue.
Diamond 2 no sound
I am so pissed that my htc diamond 2 has no sound receiving or calling but the external speaker works. Got this as a present Brand new in box 2 days ago from hong kong and i live in Canada so I have no idea how I can get this fixed. I emailed the hong kong htc to see if I could purchase an earpiece to fix it hopefully I could or else I would have to ship it back to hong kong. Which if I ship by express one way is $60-$80 for a 1 - 3 day ship. If anyone knows where to get these earpieces and have any clue to installing it would be greatly appreiciated.

I just had the exact same problem with my phone after only 2 months!!... This seems to be becoming a common fault with the TD2. Very poor quality indeed. .
Hong Kong
90% of all Hong Kong Merchants are CROOKS! STAY AWAY
I ordered Hong Kong TD2 and it came with broken earpiece so next monday I hope it will work
We need to find out what these devices have in common so others with Topaz phones from the same batch can be prepared.
There is almost certainly a portion of the Serial Number which you all have in common; Part of it will link up with a particular build batch. If we can figure out which it's from, maybe we can take the info to HTC and see if they can resolve the issue / acknowledge it and get devices replaced.

It is not. Hong Kong is one of world known shopping centre and people may find many different outlet to buy for hugh variety of goods coming all around the world. I admit some of these retailers are not doing well such as re-selling such returned items to another buyer. Anyway, it is fault of HTC that certain batch, especially the early batch, may have problem in the earpiece. I have mine 2 sets both went into problem and repaired.

Agreed. There are users in such short period having defect in the built-in earpiece is very abnormal. I don't think it is easy to obtain such information. Remember TYTN II driver issue? HTC is easily evade from any liability and still getting hugh profit from selling later devices.
Mine too same problem. Happen about a month ago. Device is just 8 month old which i bought in Dubai. I am no longer in Dubai, so cant go for warranty. I tried with a phone shop, they said i dropped my topaz into water. wtf!!

[Q] Sending my phone in for repair under warranty

Hi,
So about a few months ago I noticed that whenever I took pictures on my phone's camera in dark lighting, there is some purple-ish tint throughout the whole image, most noticeably around some of the edges of the photo. I had heard about the purple tint problem in the HTC One, but never thought it could occur in the Butterfly S! Silly me thought it was maybe a firmware problem and that it might just fix itself, but recently I read that no, it is indeed a hardware problem. I definitely want to get this fixed.
My question is how do I go about sending my phone in through warranty? I live in the US but I bought my phone in Asia (since the phone was never available here). Can I just call the HTC center in the US and will they know about the phone and be able to fix it? Or will I have to go through the hassle of sending the phone all the way back to where I bought it from?
Thank you.
You'll need to ship it in and also pay a 20$ Global Warranty Fee since it's a Taiwan-only device (I'm told the same thing applies if you repair it in Taiwan or wherever you purchased it. Repair takes around 2 weeks. Important to note that the warranty is from manufacture date otherwise you will need to show them proof of purchase.
I'm currently considering this for my headphone jack problem as well.

[Q] Where can I find a working flex cable for T-Mobile T8585 US Hd2

Recently I've reopened my HTC HD2 to glue the glass+digitizer better to the case since the replacement BUT I accidentally damaged the flex cable by cutting the UP/DOWN volume buttons flex....
...I've already ordered 3 from eBay and from different sellers and the symptons were:
1. Bad Sound through loudspeaker (static), Camera was flickering with pinkish tone
2. Bad Sound through loudspeaker (static), No Vibration
3. Bad Sound through loudspeaker (static), Vibration worked but no Proximity sensor (literally)
Suffice to say I've waited nearly 1 month for each arrival...spend time to install and make a video to show the seller I was not lying...and now I'm using the HD2 without the volume buttons but with everything ok....I'm nearly Ok wasn't the fact that the Vol keys have a number of functions I use: Camera button, Silence a call and most important flash new rom's.....
Can anyone help me find one that REALLY works?
I would say your best bet is getting a used device being sold with dead or broken original digitizer.
Prices are very reasonable these days & even if twice the price you will reclaim the cost by selling other genuine parts via eBay.
Quality of chinese manufacture on mainboard flex is going be a problem as they love minimal manufacture cost (even leaving components out:-O )

Maybe you're right...and that's what 'll try to do next time. What I don't understand is the large number of happy costumers buying those flex's and reporting no problems...
I think a lot of people write feedback before fitting or testing well.
I do suspect some work well but indeed they will not be near quality of original.
The digitizers & button boards are good but flex is one of those things where genuine if possible works out best.
Should be easy pick up a salvageable HD2 besides bad mainboard or digitizer & with your gained experience strip for parts.
maybe you can try on www.aliexpress.com
I recently bought this one - http://www.aliexpress.com/snapshot/6129733847.html , but i've given my HD2 for assemblage, as I am not able to flawlessly do it personally . i can post the results in a weeks time and tell you how it works.

Same as ones on eBay - amazon, you'll find that seller on eBay too.
Main flex is always best salvaged from a cheap broken HD2 rather than copy part as just too complex & important for cheap china copy part.

Check if screen is original

Hi,
Last week I bought a new Sony Z3 compact, and I'm having some difficulties with the touchscreen. I'm experiencing some of the sensitivity / bouncing problems I saw in the forum earlier. It's making typing sometimes very difficult.
The build date of the phone (which came with no accessorizes like headphones or something, only a charger, something strange as well) is: week 35 of 2014. Rather old for a new device. I'm wondering if my device is completely new and it's not just a repaired phone with a repaired screen. Is it possible to check whether the screen is original?
The reason I went to the shop was that they're willing to buy my old iPhone which I got temporarily, because my Nexus 5 was broken. I hated the iPhone and they gave me a good deal for the Z3C. But I hope that I bought a new phone and not just a repaired one with a cheap display....
The headset itself doesn't have a single scratch, it looks completely shiney btw
It's possible that they gave you a refurbished device true, but if I'm correct those devices or any sold by any store 'must' be repaired with OEM parts, so it's highly unlikely that they used 'cheap' parts to repair it. You could check to see if the phone is still waterproof by doing the pressure test or putting the in water.
Even phones with OEM parts had the same problem that you described.
If you're not satisfied I'd suggest to go back to the store.
P. S. There is no way to check whether the screen is original or not.

Hi Dsteppa,
Thanks for your quick reply. The pressure test seems fine, so I'm guessing the phone is still water proof. Perhaps an update to Lollipop will fix it. Maybe I'll go to another shop first and compare the two screens before returning my device if Lollipop won't help.

My Note 8 microphone died.

My Note 8 mic died today :crying: I can hear the callers but they can't hear anything from me. If I switch to speaker, they can hear me. I checked all settings and did factory reset, didn't solve the problem. I took it Samsung service center at Rama 9 Bangkok ( I live in Thailand). They tried "deep" re-flash (whatever that means), but didn't fix. Seems like my phone failed their diagnostics as well. They opened up the phone and confirmed it's a hardware failure. Fortunately, everybody who preordered Note 8 over here get 6-month brand new unit replacement and 1-year accidental screen damage warranty as part of promotion in addition to free AKG 230 blutooth speaker, some military grade cover, pencil style s-pen. So for this case, they processed mine to get brand new unit as replacement. I have to wait 7 to 14 days. I really hope my replacement phone will be problem free.
I'm just glad I haven't purchased whitestone and only bought some cheap screen protectors. I was also considering of rooting it. Now that this happened, I don't think I'm going to do it at least until my warranty runs out. I really don't want to lose my accidental screen damage warranty. I have a feeling that I'm will be using it.

Always sad to read this sort of post. As you know there will always and I mean, always be lemons. Try not to let this sour your Note 8 experience though. I do hope you get this situation resolved in a satisfactory and speedy fashion.
Let us know how you get on. :highfive:

The weirdest part is that the mic is the same either for regular call or speaker, the only thing that changes is the output audio source...seems more of a software issue than hardware, that for some reason is not opening the mic on regular calls...[emoji848]interesting...

Do you have a case on it? Take it off.
I ask because I first used a hard case and the mic didn't work always...the bottom port seemed partly covered, not much but obviously enough. Take the case off and all good. I now use a goospery soft case and it's fine.

While I don't know which microphone is used for what, I'm pretty sure Note 8 has 2 microphones: 1 on top and 1 on bottom, so maybe it is using top mic with speaker on, not the bottom one?

Both are used for noise cancelling
Update. I got my sealed brand new replacement couple days ago. My new phone is manufactured in Sep 29th. Everything is good. Mic is working. Screen is good, no light bleed at all. They even unboxed and did diagnostic of new phone with me, mainly checking the screen for any dead pixel or touch sensitivity issue, before I signed paperwork. I'm super happy with Samsung Thailand services, far far better than in the US.
Now let's see if I'll ever have to use 1-year free screen replacement. I nearly dropped it this morning.
That's a hell of a promotion. Wish we'd get that here in the States. The Galaxy 360 camera I made the mistake of choosing (instead of a sd card/fast charger) is a piece of doodoo.

My wife got the 360 camera during the S8 promo for a "mere" $50 extra. It's still sitting in the box and not being used. Waste of money for us it was.
Was actually thinking about using it. , Does it have any real uses ?

Mine is giving trouble too, but the entire circuit board there seems to have died on me after about a week, the LTE strength suddenly became terrible, and I found that if I applied pressure on one of the antenna connectors in a specific direction the strength would jump up to normal.
I'm waiting for replacement parts to be available, and I noticed that the USA version that ifixit has a teardown guide for has a newer revision of this board, made a week or so after mine. Must have had some of the early ones fail prematurely... The rest of my phone works flawlessly, fortunately.

Yes. Put it on Ebay and hope some poor schmuck pays you your $50 for it.
Op, that is the reason to buy only from authorized official dealers! The people who get their devices in grey markets most of the time have troubles with warranties
I have the same issue, blowing into the usb port seems to fix it temporarily. Hope this gets sorted out with a software update.
