for the record i have 3 different magnetic pouches and all of them cause this problem no matter which way around i put the phone. it is less if the back of the phone is presented to the magnet but still there.

take your phone and wipe along the back a bit with y,the case flap. evenrually the screen will unlock. then all that is needed is t,for the case to keep pressing on the screen ans it never switches off.

since the new noreve i am good. unplugged this morning and it is now 3pm and battery is like 80%. i also have re-enabled the 3G,the max power wireless and all others. only i still have the smartflex enabled.
