Android browser switching phone to silent mode

i'm not sure i understand when you say that the browser turns on....on its own? what do you mean? what phone do you have? how do you know that the browser is the one muting your phone?

 

Try this, go to settings > apps > browser > storage, clear all data, clear all cache. Sounds like you may have a rogue script running.

 

weird....never heard of this. @Trom makes a great suggestion. but i would clear cache for the browser as well.

so there are two things you can also try if clearing cache does not work:

1. put the phone in safe mode. this will will not allow any third party apps to run. if it happens in safe mode then, something is wrong. it could be either a hardware issue or software and a factory reset might be needed. if nothing happens while in safe mode, then yes something was installed onto your phone to cause it. it could be a rogue app or something more nefarious.

2.factory reset. this should work as well, provided that this is a software issue and not hardware.
