No action after touching the touch screen
• Check whether there is any damage to the screen. If yes, please back up your
data and take your device and proof of purchase to our repair centre to get more
professional technical assistance.
• If the issue occurs while using a third-party app, make sure the app is compatible
with your device and Android version. Try uninstalling the third-party app.
• Check if the issue occurs during charging. If yes, we recommend trying the
official charger and data cable.
• (Note: The voltage instability of non-standard chargers and data cables may
cause the touchscreen to become unresponsive).
• Make sure the temperature where the device is being used is neither too hot
nor too cold. The standard working temperature of the capacitive touchscreen is
-10°C~60°C. Excessively high or low temperatures will cause the touchscreen
to become unresponsive.
• If there is a screen protector on the screen, see if the touchscreen works after
removing it.
Make sure there are no stains such as water or sweat on the touchscreen. If
there are, wipe the screen and try again.
• If it still doesn't work, reset the phone or update software
