I don't know if this has been mentioned before, but the sound on my phone randomly will go down a lot, and only a restart seems to fix it. I'm talking everything; media, alarms, ringtones, etc. I'll lock it for a bit, and when I come back to it the sound is at an unhearable volume. Is there any known fix for it?
There's no official fix for it but there is a work around. This is what I do on my phone.
I notice that everytime when I have sound on, whenever I get notification or phone ring, my volume becomes really low. Yes. Including ring, notification, music, etc. So, here's what you do.
-If you are in vibrate or silent mode, turn the sound on.
-Call any number and let it dial for 5 seconds. (I call international random number so that I don't get charge and the phone doesn't dial. It just stays in dialing screen but nothing happens.)
-Then end the call. You'll hear the end call sound. A loud beep than normal.
-Your volume is back to normal.
-Go back to silent mode. (Staying in silent mode keeps your volume normal)
Note - If you don't hear loud beep when you end the dummy call or if your volume didn't set back to normal, try again and keep the dialing screen on longer than last time.
This fixes everytime for me especially on the car when I have it connected to my car stereo.
