I have posted this on the US forum by mistake but it might give me some answers.
At 0.55 every morning my phone bleeps for 1 minute. This happens even when the phone is turned off. It is not one of the standard notification sounds and there is no indication on screen that this is happening or has happened. During the one minute that this is occurring the phone locks up meaning I can't turn the sound down or turn the phone off if it was already on. I have tried all the suggested solutions that l have found on various Internet forums that refer to notification sounds and have set the phone back to its factory settings but to no avail. Before giving up on the problem altogether any help or suggestions would be appreciated. Thank you. U
