Had my Optimus Elite for less than a week now, and suddenly the power button seems to be broken. Ive not abused the phone in any way. What happened is it was on and working fine when I realised my power button wouldnt lock the screen or turn the phone off. I pulled the battery, and I replaced it shortly after. Now it wont come on. Its fully charged - I can see that from the battery immage that pops on screen when I first plug it in. Any suggestions? Any other way to get the device to come on?
