I signed in with a different Gmail account a few days ago, and since then whenever I try to download an app from Google Play Store, it shows that it's getting prepared for download but the download never starts. (I don't think that should be the reason.)
Also, if I keep my phone on for 5 minutes while downloading an app, it switches off automatically.
I've been using this phone for a year now and I never faced this problem before.
I restored my factory settings and the problem still persists.
Any idea as to why this is appending?
(if relevant, my device is a Samsung Galaxy Ace with Android 2.2)
