Hello. I just got a refurbed pre because my original one had a few issues. anyways, got it all updated from 1.2 to 1.3.5.1 and all was well. that was this morning. a few hours ago the pre started showing the airplane mode/ power screen like when u hold down the power button. its doing it every 5min. also, when its doing this, if u press the power button it does nothing.

after a bit, the pre snaps out of it and works fine for a bit, then its starts all over again.

has anyone had this issue?

thanks in advance
