turns self off!

Mines done the same thing twice.........its bloody annoying!

 

This may sound like an obvious thing, but has the SIM been inserted fully so it clicks in? A mate had a similar thing happen with his phone (also a portal) and it was simply a case of he hadn't pushed the SIM in all the way to get the click.

 

Same Thing happens to me, i think its because the sim card isnt inserted proprerly, like in the sd card it fits in perfectly, but its impossible in this phone

 

I had a similar problem that my phone would keep re-booting itself. It had nothing to do with the power off button mentioned, as it sometimes happened when it was unlocked and in use. I was about to send it back to t-mobile for repairs but they said it could take upto two weeks before I got it back. I was also get process errors when the phone re-boot. In the end I deleted a few apps to free up more memory. Since then it hasn't re-booted itself or had a process error. Not sure it's the same problem for you, but it's worth a try.

 

i found that turning the wifi sleep policy to never(it's in wifi advanced settings) solved the problem for me

 

Happened to me once. Restored it to factory settings and haven't encountered it since. Before I got the random rebooting issue though, I had frequent FCs at startup so maybe something got corrupted. Backup before you do a reset.
