I know there are alot of threads on the issue, but I haven't found one that describes what is going on. Hopefully you guys can point me in the right direction.
Galaxy S7 SM-G930V
Android 7.0
Build NRD90M.G930VVRS4BQC9
Purchased this phone used, everything seemed to be working ok. I didn't notice any sounds since I usually keep my phones on vibrate 90% of the time. Except the alarms. After using a couple of hours, I noticed the loud speaker seemed to have stopped working. Then I noticed sound would come back. The sound is on and off through the day, I have confirmed it is only the loudspeaker as head phones, bluetooth and ear speaker works. I have tried just about everything I have found on the internet (see below). I did purchase and replace it with a new speaker and it has the same effect.The phone was in mint condition when I purchased it, no evidence of water damage or anything.
It *seems* to happen the most (not always) when the screen lock kicks in and I unlock it. And sometimes that brings the sound back for 5 minutes as well. I am perplexed as to the cause.
I am beginning to think this is software related, possibly even SIM (I swapped my iphone sim card to it since I came from Apple).
What I've tried (some of them multiple times):
-Full reset
-Reset just settings
-loud speaker replacement
-wipe cache
-Prevent USB audio routing
-PSM changes
-Removed Chrome
-downloaded some audio app I found helped others
-made sure the contacts were connecting to the speaker fully
-"flexing" the case
-volume on/off
-turning off OK Google
-Easy Mute turned off
-removing all third party apps
- clearing cached data
I have also noticed, and it may not work on my phone, but dialing "*#0*#" or pressing Home and down/up volume keys, doesn't bring up a menu them I have seen in forums discussing this sound issue. Some type of options menu. Don't know if that helps.
At this point I have ordered a used S7 with a cracked screen in hopes I can swap the logic boards.
Open to ideas. Please let me know if you would like more information
Thanks!
