To Next PageTo Next PageWhat to do if my TCL 40 SE cannot charge or charges slowly?
If your TCL Cell Phone cannot charge or charges slowly, and there's visible damage to the charger USB, the charger itself, or the charging port, back up your data and take your device and proof of purchase to a repair center for assistance. Otherwise, charge the device with a TCL official charger for at least 30 minutes and try again.
Why does my TCL 40 SE Cell Phone keep lagging or freezing?
If your TCL Cell Phone system lags or freezes, start by restarting your device. Ensure your battery is at least 20% charged. If too many apps are running, tap the Menu key and 'Clear all'. Uninstall unused apps to free storage space and remove any third-party apps that might be causing the issue. For poor network connection, enable Airplane mode briefly or move to a better location. As a last resort, try resetting or updating your device.
Why does my TCL Cell Phone keep rebooting?
If your TCL Cell Phone reboots by itself, it could be due to anomalies in a file; in this case, it is recommended to continue using the device normally. Also, try using the official charger and data cable. Ensure third-party apps are compatible with your device's Android version, and try uninstalling them. If the problem persists, try to reset or update your device.
