7 Troubleshooting
7.1 What should I do if my device reboots by itself?
a) If the issue appears occasionally, it may be caused by anomalies in a file. It is recommended that
you continue to use the device normally.
b) Check if the issue occurs during charging. If yes, we recommend trying the official charger and
data cable.
c) 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.
d) If the issue occurs while using the built-in app, try to reset or update your device.
7.2 What should I do if my device system lags or freezes?
a) Try to restart your device.
b) Charge your device until the battery level is at least 20%.
c) Too many apps running in the background or the system cache not being cleared may cause a
system lag. Touch the Menu key at the bottom corner of screen to view recently used applications.
Touch “Clear all” to close the tasks.
d) Uninstall unused apps from time to time to ensure that your device has sufficient storage space.
e) If the issue occurs in third-party apps, please uninstall the third-party apps responsible.
f) If you are playing a game, watching online video or listening to online music, your device may lag
or freeze because of a poor network connection. Enable Airplane mode for a few minutes, then
disable it and check your network connection again. Alternatively, move to a location with a better
network connection
g) Try to reset or update your device.
7.3 What should I do if my device cannot charge or charges slowly?
a) Check if there is any visible damage to the charger USB, the charger itself or the charging port of
your device. If yes, back up your data and take your device and proof of purchase to our repair
center to get more professional technical assistance.
b) Charge the device with a TCL official charger for at least 30 minutes, then try again.
