Well,look.Let's say we have the app working with the keys locked as usual.We press the * and right key and the are unlocked.We press for a few seconds the "back" key,this with the arrow and we end the app.That's why I think it's useless.In addition to this,my sister used it to her K810i and the phone showed the WSOD and I flashed it,I updated it's EROM,but nothing,so we sent it to the SE center and we paid 40EUROS because of a fuck**g app!:mad:
