So i got a galaxy s6 about a week back and it worked fine for the first couple hours. Then i began to get audio problems where i could not play audio, videos on instagram twitter and youtube wouldn't load either. I exchanged the phone and i got the same problem once again.
Video problem:
I could not watch any video in my device.
In Facebook application and got this error “failed to play
video an unknown error has occurred".
YouTube app. got this error "there was a problem while playing
touch to retry".
Gallery video even if it has been recorded by the camera earlier.
Audio problem:
I’m not able to play any music, got this error “sorry, the player does not support this type of audio file." and this file is the "Over the Horizon" song which came with the device.
When i go to the settings to change the ringtone I am not hearing any sound for all them.
I did not put the phone in silent mode but no sound for any received calls, notifications or SMS.
I tried everything i know to solve this issue, I done all of the following but it does not works:
Clear the cache memory.
Uninstall all the application
from the device.
Factory reset.
Update software.
The only thing work with me is to restart the device but it will not solve the problem permanently, it will happen again after few hours.
