I typed in my PIN for my lockscreen this morning, hit the tick button as usual...and NOTHING. My screen is now frozen, I cant turn the phone off, there is no battery to remove. Its just stuck. Any suggestions? Its an OPTUS phone.
Solved! Solved: Go to Solution.
You could try a hard reset (You'll loose all settings and data on the phone - it will return to how it was on day one)
Read the 'How to factory reset your phone with hardware buttons' on this page
Yep. Returns to your day one out of box phone.
Note, may not work anyway but something to try if you can't figure something else out.
Maybe take it into an optus store?
LET IT GO!!!
Before hard resetting i would try. holding the UP volume button and the power button for 10-20 secs, this may put it into a reboot into safe mode at which point just restart phone as normal.
Hey @Rozz, @SteveV has offered a good suggestion. Rebooting your phone in safe mode will load Android OS without any third party applications. If the handset can be used as normal whilst in safe mode, you can confidently conclude that a third party application is the source of your trouble.
I guess the tedious part would be going ahead and removing each third party application one by one until the handset is able to boot up normally. If you have any other questions for us, feel free to send them through
