I was curious who has had to exchange their tab for another one. I picked one on Monday. Worked great for 2 days then the screen went fuzzy in landscape mode. Tried reset and a hardware reset but did not help. Went to BB last night and exchanged. Last night it worked great. Today it keeps asking me every 2-5 mins if I want to shut down. What do you think? Is there a fix or should I go exchange one more time? Third time is a charm they same.
