Before you buy a new cell phone or new tablet, please try the following procedure to repair your device. First charge your battery, backup your important data if possible and in most cases take out SIM and SD card. It is impossible to recover your data after doing a hard reset, so online backup is always important. For all of your data, a backup should be done on an external device, hard drive, raid system or media. With or without insurance, if your cell phone lost, damaged or stolen at least your invaluable data is backed up in a safe place.
To perform a Dopod 828 soft reset
If your Pocket PC Phone responds slowly, stops responding, or freezes, you can soft reset it. A soft reset causes the Pocket PC Phone to restart and re-adjust memory allocation. Unsaved data in any opened applications may be lost. Use the stylus to press and hold the Reset button, as shown below.
Dopod 828 full reset
A full device reset clears memory, deletes all data and restores the Pocket PC Phone to its default settings. Programs installed at the factory remain, erasing all data that you have created and programs you have installed. Press and hold the power button, and then use the stylus to press the soft reset button at the same time. Be sure you have backed up all your data in a SD card or on your PC before performing a full reset.
