I purchased a Galaxy S through Bell in Canada a few days ago and it's been great, except for an issue that started just this morning. The phone keeps bringing up the context menu at random when I have not hit the key to do so. Sometimes I can use it for ten minutes without an issue, other times it will flip on/off repeatedly ever few seconds for a 15 second period or so. This is definitely not an issue of me pressing the key by mistake; I can lay the phone on the table and it will trigger the key on/off on its own. I've tried: - Cleaning the screen several times - Rebooting - Deleting pretty much every app I downloaded - Total factory reset (from the boot menu) After the factory reset the problem still exists, which leads me to believe it may be a hardware issue. I haven't seen any other posts regarding this issue, has anyone seen something like this before?
