Make sure your battery is fully charged

  1. Whenever possible, use the AC adapter and plug your phone into an external power outlet.
  2. You can use your smartphone while your battery recharges.

Restart your smartphone

Restarting your smartphone causes its software to reload and renews your connection to the network, which can fix some problems:

  1. Remove the battery.
  2. Wait ten seconds.
  3. Reinsert the battery.
  4. Turn your smartphone on.
  5. Your smartphone is restarted.
  6. If these steps are unsuccessful, visit a Product Care Centre to have your smartphone inspected
