Lately my phone makes an annoying sound when unlocking the screen. I don't have "Screen unlock sound" checked in the setting. I googled and found few people complained about this issue but no solution has been found yet. I tried checking and unchecking the setting and restarting the phone many times but still no joy. A hard reset might help but i don't want to do that if not absolutely essential.
This is not me but just found on youtube and this guy seems to have exactly same issue.
Anyone here had same issue and found a solution?
