10.1 Keypad Introduction
Generally, a smartphone has only a few keys. U9500 has six keys, including three keys
commonly seen on Android smartphones, a Power key, volume up key, and volume down key.
The battery used for U9500 cannot be removed. Therefore, the Power key is designed with a
forcible power-off function, which facilitates scenarios, such as software upgrade. To forcibly
power off the phone, press the Power key for at least 10s.
Figure 10-1 shows the U9500 keys.
