So, I was walking down the street and got a txt message. I held the phone in the landscape position, unlocked it and the menu appeared in portrait. It wouldn't move round to landscape so I struggled to reply using the keyboard with two letters per key (instead of the landscape keyboard), dodging the lamp posts and tree's...
Later on, I put the phone on vibrate, then back to normal but my phone no longer rings so it's as if it's on silent!
Also, I was typing a message in landscape and the keyboard kept disappearing so I'd have to click for it to pop-up again. And if you get a txt message whilst composing one it's reallllly sluggy!
Go to Options then Security Options then memory Cleaning it makes my phone a little bit faster on opening programs and on when i switch between landscape and portrait
