after repair : caller hear their echo and light/near-sensor not working - Google Pixel 4a Questions & Answers

Hi there !
After I changed housing+battery+display of my pixel 4a (not 5g) - I got the following problem:
Every phone caller hear their echo. When I reduce the volume its better but the problem is not gone.
When I switch to speaker mode its all fine. All protective films was removed during the repair. No parts got damaged. Ive used (expensive) original Google Parts for the repair
It seems to be a build-in "bug" that the software prefer the noise-cancelling-microphone (next to the earpiece speaker) as main microphone instead of the default mic on the bottom of the device.
Ive already send the device to google for repair but they decline the repair because there was "unauthorized" repair ....
Interesting is that many Pixel 4a users on the web got the same problem after repair - but it seems to be there is no solution.
Also the light/near-sensor is not working correctly :-/ But I think it was already bad before repair
Already done fully factory reset, safe mode but nothing solved the problem

I have fully disassemble/reassembled , replaced screens,replaced finger print sensors , battery's and have never ran across this on 4a's,,, I have seen something similar on a htc u11 but that was caused by incorrect firmware,, I know you said you factory reset but have you done a complete reinstall using the android flash tool? Also when you say replace " housing " iam assuming u mean back cover , and if you replaced the cover just make sure all contacts points match the old back cover

Thank you very much. I will try a reinstall in next days.
When I reduce the volume while phone call the caller doesnt hear his echo then. So I think the contacts will be fine on backcover.

I have exactly the same problem. I also replaced the housing and the display. Both microphones are working correctly. Also on Whatsapp calls I don't have the problem. But if I go to loudspeaker during the call, the other person can't hear me anymore.
I thought maybe a custom rom could do the trick...?
Cheers
Edit: Let me know if the reinstall helped.

Not really. The fully reinstall also doesnt solved the problem...
I installed the latest Android 13 beta build via Android Flash Tool but the problem ist still the same.
Google declined the repair because of "unauthorized repair before".

Damn! Thanks anyway, so i can safe myself the trouble...
I wonder if there is no way to control the microphone choice manually...

[Q] Motorola Atrix 2(MB865) doesnt detect mobile network

Hi,
I have a Motorola atrix 2. All of sudden it stopped detecting mobile(sim) network. It was working fine , in the morning when I woke up , when i tried to call it was showing flight moded is on and when i tried to to disable flight mode I could not do it , I did a factory reset , it didnt not resolve the issue. I thought it was sim problem , i changed the sim , that also didnt work. I tried recovery it also did not work. Sometimes it detects network but i could not make any call.Most of the times it doesnt detect network(it shows red plus sign).When i try to search for networks , it lists networks after 3-4 minutes(Vodafone , airtel , idea etc) ,But i fails to register with the network.
COuld you please suggest a solution. Is it hardware or software issue?
Thanks,
Hairsh

There is a file called "radio.img" it's the software part concerned with cell network so probably if the problem came from software it (would) be that file, so please answer this Q first:
have you played and flashed some ROMs and Kernels?? is your phone rooted?
No I have not flashed or played with ROM or Kernel. What I did was my phone was attached to my laptop as USB storage and I removed directly(not safe removal , did not do safe detach). My phone is not rooted , Initially I had Gingerbread(when bought) after that I got official ICS update.

Great...now you need to fxz (it means flash the original Motorola firmware and restore it's initial state)
so here is what you need:
1) The same firmware (that's why I was asking you about system version)...download from here
http://sbf.droid-developers.org/download.php?device=17&file=351
copy it to desktop
2) Motorola Driver
http://www16.zippyshare.com/v/65297309/file.html
install it.
3) RSD Lite (it's the application used to flash)
http://www16.zippyshare.com/v/85618478/file.html
install it.
>>Now charge your battery to 100% that's very important.
>>backup your important info. from contacts to messages..etc.
>>Turn off your phone.
>>Enter Fast-boot mode by pressing (volume up+ volume down + power button) at the same time..the phone will turn on with a menu...press volume down to move the selector to (AB Fast boot) then press volume up to enter that mode.
>>you now should see "Battery OK"
>> Connect your phone to PC with the usb cable and wait to see connection has changed to "USB Connected" in phone
>>open RSD Lite and follow that video instructions:
https://www.youtube.com/watch?v=AHaEHjSzvQQ
Caution: Don't ever try to cut the flashing operation or your phone will be completely dead...so it's recommended to disable your antivirus while flashing and other services..just leave your PC alone till RSD Lite finishes the flashing.
It's not hard to fxz but please be careful with every step...... HAPPY FLASHING
My internet is slow , its taking time in downloading the firmware image. I will update you once I complete the process , thank you very much for the kind help.
Flashing was successful but for my bad luck the problem still exists. I think its an hardware issue. Do you have any idea? is it repairable? if repairable what would be the cost? Thank you very much for your support.
Good news ,it started working , i rebooted some 4-5 times after flashing firmware ,it started working now.
Thanks for your support. Thank you very much.
Sorry to say that my phone has gone mad. Now it shows network , but I could not able to make call ,if I call anybody it just gets cut and I am not able to receive any calls. Earlier it worked for some time i received 2 calls and I made 2-3 calls. Now calls are not going and not coming also.

I see that flashing original firmware doesn't help....sorry to say but it's now definitely a hardware problem
I guess that when plugging out the USB cable "specially if you unplug it slowly" some current leakage has reversed back and burned a tiny connections on the board.
actually I don't know the repair cost in service center...it depends on how much damage happened on board.
Note: maybe the battery is part of the problem...if your battery isn't genuine it may lead to that crazy behavior specially when making call or receiving calls as battery is required to raise up it's current to wake up some chips and provide more power to the antenna....if the battery was bad or damaged it can't raise it's power suddenly so system will goes crazy and may restart or freeze...etc
Make sure that your battery is genuine and not too old or that generic Chinese bad batteries as they aren't stable and may cause a current spike "extremely bad for electronics" when moving from charging mode to discharging mode and that's exactly what I think it happened to you.
Thanks. I will try to take it a repair centre , Lets see whether they can fix it. Bad part is Motorola no more provides service for Atrix 2 in India. I have to find someone who has expertise in fixing Atrix 2 problems.

Hi Harish,
Before you go to the service center, try changing your SIM card.
I once had problem with my new MotoZine restarting everytime I clicked a pic. I took it to the service center, they reinstalled OS. That did not work. Then we changed the sim card, and miraculously it worked.
I know its weird, but its worth a try.

Major sound distortions only when taking a call. (Moto G4 Play)

Bought a Moto G4 Play (Verizon Prepaid version on Android Marshmallow) during black Friday and have been unable to use it because of this issue. Every time I take a call (happens even in Skype or Talkatone) all the audio on the phone including the call becomes heavily distorted and low quality. As soon as the call ends all audio reverts to normal (I noticed the sound distortion when trying to watch netflix while using skype with the gf).
I have tried so many sources and literally no one has any clue what's wrong with the phone. Here's a short list of things I've done to try and fix this issue:
1. Replaced the phone (audio problem still happens with the new one)
2. Swapped sim cards
3. Factory reset
4. Cleared the cache
5. Reset all app settings
If anyone has any clue why a phone's audio would distort during a call and go back to normal afterwards please let me know. I've contacted Motorola support and they had no clue how to solve the problem.
Please if anyone knows what's wrong with my phone I really need help I can't use my new phone at all the way it is now.

No speaker sound/rings, apparent hardware issue?

A few weeks ago my completely stock Galaxy S6 stopped ringing. No rings, no notifications, no music, no speaker output from any source at all. To make sure it was not a software issue, I tried booting in safe mode, then also installed a custom recovery and a couple of ROMs.
Since I needed to replace the battery anyway, I ordered a replacement speaker on the assumption that the speaker had failed. I installed it, and still got no sound. I am fairly certain that the speaker contacts are connecting with the main board, as when I reopen the phone there is a divot on each of the contacts.
I am asking for help here as my searches have been fruitless, always referring to software repairs.
Can anyone suggest what the problem might be? What can I do to figure this out?

If you installed the stock rom and it still -persists has no sound,i think you should send it to the service...
I have the same problem, even tried msm tool and I can't do any phone call... does it really is a physical issue? or do you eventually fixed it?
I see that there are more people with this issue:
https://forums.oneplus.com/threads/the-speaker-and-the-microphone-dont-work.1132026/
I'm not fully sure if it is a physical problem, but I already tried several methods trying to recover from this, Msmtool (HOS), Fastboot Rom, etc, without any luck.
Any news about this issue? oddly enough, my phone started to act as nothing happened, with sound and everything normal just one day after another reboot... and it was working fine for more than a week, but now I'm not sure if I should apply for a warranty

Nokia 5.3 doesn't vibrate

Hi, I can't find any thread about this topic, I hope I didn't miss anything.
The problem:
In October, I've bought Nokia 5.3 with Android 10 in Czech Republic (Europe, probably German or UK distribution) and I found out it doesn't vibrate. I tried an app that's dedicated to vibrating but it doesn't do anything and switching to vibrate-only mode using the menu invoked by volume keys switches the phone basically to a full DND mode.
I searched the Internet and found a few reports of other users of Android 10 phones with a similar problem. (None of them, however, with a Nokia phone, at least not concretely Nokia 5.3). I hence assume it's not a defect of my phone but rather a software bug in Android. I'm of course rather reluctant to test this by returning the phone and getting a new one thru warranty because I did put some time into setting this one up. I reached out to the Nokia support but they were unable to help me further than advising me to check a few settings (which were OK) and told me I probably need to wait for an OS update.
The question:
Do you have Nokia 5.3 and do you or do you not have the same problem?
Thank you very much for your experience and suggestions.
Hi,
I have Nokia 5.3, bought it recently. However I hate vibrations so that was the first thing I disabled in the settings. It was vibrating like hell . Check your phone settings, there is an option to turn it on and off.
Cheers!
Hi toppicks,
thanks for confirming that it's obviously not a software issue. I checked all the settings I could, none of them change anything.

Finally, I found time to do the factory reset, it didn't help. I tried with the SIM card and also without it, the phone still doesn't vibrate. I'll go return it to the vendor on Monday, hopefully, I'll get it resolved that way.
