I got my PRS-T1 in January so it's around 3 months old now and in general I'm pretty pleased with it. But in that time I've had two screen freezes: I'm reading as normal when the screen stops responding to finger swipes, then alternates between a blank screen and a circling arrow symbol. All I can do is reset it, which fixes it (although the first time that also deleted my DRM authorisation so I couldn't use it again until I got home to re-authorise it - grrrr !).
Question: is this normal, do other people suffer this kind of periodic annoyance - or is there a fault and I should get it fixed ? Being only 3 months old it's still under warranty.
All opinions gratefully received, thanks in advance !
