To restart your phone, simply turn it off and back on. If pressing and holding the POWER button doesn’t work, then remove the battery, wait for a few seconds, reinsert the battery, and then turn the phone on.

HTC Mozart T8699 factory reset (hard reset)

If you’re passing your phone on to someone else or your phone has a persistent problem that cannot be solved, you can do a factory reset (also called a hard reset). This returns your phone to the state it was in before the first time you turned it on.
Factory reset is not a step to be taken lightly. It will permanently delete all your data and customized settings, and will also remove any apps you’ve downloaded and installed. Be sure to back up any data and files you want to keep before you do a factory reset.
