I had few blackouts today and yesterday evening... Phone stops responding - first freeze was at the point where i want to unlock keyboard - no matter what i pressed the screen stayed the same.. so i puled out battery at the end.
then today phone blacked out - (blank screen) few times... just red led blinking, but just until i pressed something on keyboard. then it stopped blinking all together
pulleg out media card (but i am sure it was formatted under 4.5)... will see what happens next.
