Hey guys, my phone now often says sdcard dismounted. Had to off and on the phone again so that it detect the card. Does that means my card went bad or something wrong with my phone?

Also, it just happened to jerk a few times in a day, say when I typed in something, the keypad was slided down as if I slide it down. Sometimes when playing games, it just not responding for a sec and came back.

As for the new updates, after I updated, opening the camera app shows no image, but a quick reboot fixed that.

Guys, my speaker mesh/grill comes off from its place, now it gone missing.
Any idea where I can get a new one?

How come for a device which is rated waterproof, after using it in a pool for a short period to take pictures,now the mesh grill comes off, for almost 1 day, the camera launched itself.
