Do you use the Glance Background app?
About two weeks ago, my 1520 started acting similarly to yours. When I'd wake the phone, it would magically type in incorrect passwords and sometimes the screen would become jittery and freeze. So, I did a hard reset on it and restored it using the restore function during setup. After it was finished, I went through logging into all of my apps, including setting up the Glance Background app. After a day or so, the sensitive password issue started again. I figured since it always happened after I woke the phone while the Glance Background was being displayed, it might be related. I installed that app, performed a soft reset, and have not experienced it since.
This happened to me before back during the summer, so I sent it to Nokia. They sent it back after reinstalling the OS, and said that nothing was wrong with it.
What Scienceguy Labs said makes sense. I disabled Glance background on my 1320 because it was pretty buggy. Seems like a possibility.
Exactly the reason why I traded mine for the 930, its built a lot more securely and doesn't have such a sensitive screen. Not sensitive in the touch sense but sensitive in the sense that it is poorly secured to the phone which makes it finicky.
I simply turned off glance and removed the case. Still doing it. Had to reboot twice just this morning. Think I'm going to take it back to at&t today and go back to my iPhone that worked correctly since the very first iPhone. Sad.... I really like the interface, layout, and size. Very disappointed.
The next morning :
- I've uninstalled Glance Background beta. Funny, the pictures I'd selected still display (in rotation) even though the app is gone (several reboots, soft reset). Picture display (on / off) controlled by Glance, but NO selection of background Glance pictures.
- Phone has behaved correctly (so far) - today will be the true test (case on all nite while charging, possible heat transfer, etc) - I have the S wave, TPU (Fosmon) case on it
time will tell
