I'm using lumia 920 and want to backup my sms. But unfortunately I can't slide the button on (as picture attach). It always back to left (off). What should I do?
@phonohead : Yes, I can set them to backup, eventhough I never check whether it back up or not.
@hamzie11 : Its original ROM. As long as I remember I only got 1 OTA update. detail on picture
I'm thinking about getting hard reset also, but wouldn't it make all my data gone (sms that haven't been back up?). But if there's no other way, than I have to let my sms gone.
might be a silly question, but you have added a Microsoft account to your phone yeah?
Also give a soft reset a shot (power + vol down and hold till vibrate)
