Hi guys, I'm getting an odd problem as well.
It started a few days ago where the touch screen would not work, only for a few seconds and then it started working again. Then I completely ran out of battry.
When I plugged it in and woke up the next day the screen was totally unresponsive. tried a soft reset which didnt work but then a hard reset seemed to do the trick.
The problem is now that when I hit the unlock button, it takes maybe a second or two for the touch screen to start working. I swipe up but nothing happens then a second later I swipe again and it works. If I lock the phone and then unlock immediately the
screen normally starts working immediately but if I lock it, wait a minute and then unlock it I have to wait a second or two for the screen to start working.
Really weird and definitely a software issue. Its not a huge issue, but is quite frustrating.
I think it first started when I added my gmail email account as a linked inbox, so I'm going to start playing around with the mail settings to see if I can sort it. Will re-post later.
