Why is my TCL 20 R 5G Cell Phone lagging and how to fix it?

  megannelsonJul 28, 2025
  If your TCL Cell Phone is lagging or freezing, try restarting it. Ensure the battery level is at least 20%. Clear running apps by touching the Menu key and selecting 'Clear all'. Uninstall unused apps to free up storage space and remove any third-party apps that might be causing the issue. For poor network connection, enable Airplane mode for a few minutes, then disable it, or move to a better location. As a last resort, try resetting or updating your device.

What to do if my TCL 20 R 5G Cell Phone keeps rebooting?
- L
  Lisa DillonAug 13, 2025
  If your TCL Cell Phone reboots by itself, and it happens during charging, use the official charger and data cable. If it occurs while using a third-party app, ensure the app is compatible with your device and Android version, or try uninstalling the app. If it happens while using a built-in app, try to reset or update your device. If it is due to anomalies in a file, continue to use the device normally.
