Mic issues after lollipop update SM-T800 - Galaxy Tab S Q&A, Help & Troubleshooting

Samsung Sm-T800
After update to lollipop 5.0.2 (5.0.1 as well) the mic isnt working anymore. Every app that requires mic can't detect voice or any noise. Before updating to lollipop it was ok. I have already reset (wipe factory) many times, tried another country official Samsung firmware and it keeps not working. When I plug the headset its mic works fine, but the device's one doesn't
Any suggestion??
Thanks!!

Car stereo bluetooth issue

Hi,
I bought a G3 one month ago. Everything works OK except the bluetooth connection with my car's stereo.
Phone is working OK but music isn't.
I checked that both phone and music are enabled.
I tried both ART and Dalivk with the stock ROM (kitkat).
I tried to upgrade to Lollipop with no luck.
Is there something I can try to make this work ? (bluetooth driver, kernel upgrade ?)
Thx
is it stock or rooted? new rom?
Does phone work with other bluetooth devices?
Hi,
I first tried with the stock ROM, then I rooted the phone and install a more recent stock ROM (can't remember the exact version v10N maybe).
I tried both ART and Dalvik each time.
Then I moved to Lollipop stock ROM, V20A.
I don't have any other bluetooth device to test the phone, I'll try with someone else car. My grilfriend's Iphone 5 works flawlessly in the car.
I'am now back in stock ROM because I had a nasty bug with the WiFi under Lollipop, it was totally broken even after reboot/shutdown. The rom is rooted.
By the way, via USB, the music works OK if streamed from the internal storage or SD, not from deezer or spotify... Any thoughts on this ?
Thx
Anyone ?

[Q] Can't get Audio thru headset after HTC One M8 conversion to Lollipop 5.0.1

So I've did a factory reset and start flashing the "Stock Google Play Edition Rom LXR22C.H5" rom again.
Since I'm Rooted, this is the one I've flash: RUU-HTC_One_M8_GPE_5.0.1-3.11.1700.5_rooted
I've followed the instruction on #2031. Everything else work.... again only plugging in the headset into the jack, does switch music from speakers to headset.
As mentioned before I've upgrade my Stock AT&T HTC One (M8) to GPE 4.4.2 and automatically received all the updates OTA to get to 4.4.4 (Audio was working thru headset and/or speakers with no problems)
The only problem with 4.4.4 is that you don't have access to SD storage. (though I found a patch to update in the system, but haven't tried it)
I like the speed, simplicity of 5.0.1. That is why I keep on trying.
Also I tried changing the Kernel - using skydragon kernel (still same problem with audio). But when I used the kernel for 4.4.4 of GPE, the booting hung at HTC logo before it showed the dead android.
So I'm lost for option other than using an app to manual switch to headset from speaker....(bummer)
Anyway new ideas to proceed are appreciated.

Problems with audio in calls from handset since changing to 5.0gpe

sorry if this is abit long winded,
hey everyone, not sure whats going on here. this is the tmob variant but i had moved over to a gt-i9505 rom dandroids stock gpe 5.0 back almost a month ago, this was upgraded from jamals 4.4.4 gpe which was working great. i installed the googly 1.2.3d kernel and that was also working well. i noticed that i forgot to fully reset all my storage and noticed jamal brought out a 5.0 rom so i swaped to that and wiped everything about a week ago and at first didint notice any issues.
then i recived a call and answered it on the handset and for the first few mins it was working fine all of a sudden something glitched and i had no audio like the call droped i hung up called back no audio. reset the phone same thing. just a day before this happened i updated the kernel to 1.2.5 googly for gpe5, so i figure this is it so i reflash and reset storage and no change. oddly this entire time there have been no problems with calls when using my bluetooth headset.
long story short i have installed and wiped one about 3 different roms including the dandroid that was working ok. i am now all the way back to the 4.4.4 jamal rom that i was on before i started and the problem is persisting. when i call someone the other party hears a high pitch squealing sound but only via the handset the "ok google" is working fine. i have not restored the nandroid backup yet.
baseband is m919uvufnb4
i have the current version of the twrp as what i have been installing everything from.
happy to provide more info. i know im still on the pre knox bootloader
and when i get home im going to try my wife sim see if that changes anything.
Update
Wife's sim changed nothing
Also wanted to say that I also read about a apn reset trick that was supposed to help. I did fix it one time but it recurred again and and since stopped working
Having that same issue gpe 9505 5.0 no audio in calls unless I'm using Bluetooth no handset no speaker
You guys Ned to update your bootloader and everything will be fixed.
You can only get so far with ancient bootloaders before the wheels come off.

How do you do that
You need to Odin the latest version NK2, you can find it in general section, ShinySide has a mega link to download firmware.
Follow instructions and you will have a S4 that works properly.
You can use chainfire's auto root in original development to root.

V495 LG TAB - Need to get back to v5 firmware

I have been using the LG v495 on 5.0.1 with some healthcare related Bluetooth devices without any problems. ATT forced the 6.0 update and it caused the BT devices no to work (or spotty at best) and also have problems paring these devices. Is there a way I can go back to 5.0.1 with these tablets? I still have a few that have not yet updated to 6.0 Possibly a way to back up the 5.0.1 from one tablet and restore it to a 6.0 tablet. Not sure why the 6.0 BT is buggy with BT devices that worked fine on 5.0.1
Any help would be appreciated.
Bump? No one has done this?
I don't have the V495 bit did you try a factory reset (which will wipe everything including all user apps, data and internal storage)?
Factory wipe does not change the firmware..

Click to expand...
Click to collapse
I know it doesn't change your firmware, I mean did you try one to see if Bluetooth improves?
Yep, several times, unfortunately, it didn't help the pairing issues.

Bluetooth issue on Nougat

Hello everybody,
I am experiecing a bluetooth issue on Android Nougat 7.0 (I tryed exactly on versions EQL1 and EQD1).
The first time the device turns on, the bluetooth works fine. Then, after a reboot, I can't turn bluetooth on any more.
If I go through a factory reset I will get the bluetooth working again, till next reboot.
On Android Marshmallow 6.0.1 bluetooth works just fine...
I would like to know if I am the only one experiecing this issue as I didn't find any thread about it.
