If
HTC Desire 326G dual sim has a persistent problem that cannot be solved, you can perform a factory reset (also called a hard reset or master reset).
Warning: Factory reset will remove apps you’ve downloaded and installed, your accounts, as well as system and app data and settings. Be sure to back up any data and files you want to keep before you do a factory reset.
Factory reset may not permanently erase all data from your phone, including personal information.
