When pressing keys especially I have recently noticed a weird clicking noise coming from the top of the phone. I am really getting worried about this phone because I pretty much get all OCD when it comes to tech especially mobile phones. This is supposed to be the best phone of 2014 yet both my power and volume rockers are quite loose and this issue with the vibration noise now ... It would be reassuring to know that other people have this same thing and its not just a faulty device... Also just 1 more thing, I have my m8 in a hard protective case and I dropped it onto cement 1m (3ft) below me.. no external damage at all but I'm wondering whether there could be internal damage? Thanks for any replies :good:
