I have my HTC one M8 now for like a week, completely love the phone however since yesterday it got stuck in headphone mode.
The following things I tried: Hard reset, Back-up to previous date, Blowing compressed air, carefully cleaning with 95% alcohol while phone was turned off, Inserting regular phones like 7 times while screen was unlocked, currently using soundabout app to divert the problem... Nothing helped.
The only thing I didn't try is actually rooting the phone however I am not sure if ill have any warranty left then.
Any other ideas perhaps?
if its an hardware problem i'm not sure there's much u can do, accept trying to clean the headphones jack
if its a software bug maybe try:
-connecting your headphones then turn boomsound on\off then disconnect them.
- hard rest while the headphones are connected then disconnect them.
-before u try a root u can just try a factory rest and u will still have your warranty and if that doesn't work its definitely a hardware issue.
