Even after putting my phone on power-saving mode, it is switching off. After switching off, the phone is not charging at all. It is showing [this error/icon]... why? I haven't kept it in any place where it would get wet, so why is this happening? This has happened to me once before. I left it on charge for 3-4 hours thinking it would charge, but it didn't. If this is happening because of a bug, please fix it.
