Sorry guys for this annoying question that you guys probably faced. But I actually looked and researched for the solution, because it was different from mine. I even replaces my vibrating motor, but it still isn't working. I don't know what the problem is. I reset my phone like 10 times, of course tried different roms (My phone's rooted by the way), I tried everything in the settings. I don't know what the problem is, so if there is a post that fix this problem or if anyone knows the solution to this, that would be great.
