Hi! I'm sorry to hear about the issue you're experiencing with your Vivo Y53. Based on your description, it seems like your phone is restarting randomly and also turning off when you use mobile data without charging. Here are a few troubleshooting steps you can try to resolve the issue:
1. Restart your phone: Press and hold the power button until the power menu appears, then select "Restart". This may help refresh the system and resolve minor software glitches.
2. Clear cache partition: Turn off your phone and then press and hold the volume up button and the power button simultaneously until the Vivo logo appears. Release the buttons when the Recovery mode menu appears. Navigate using the volume keys and select "Wipe cache partition" using the power button. Reboot your phone after the process is complete.
3. Factory reset: If the issue persists, you may need to perform a factory reset. Make sure to back up all your important data before proceeding, as this process will erase everything on your phone. Go to Settings > Additional settings > Backup & reset > Factory data reset. Follow the on-screen instructions to complete the process.
4. Update software: Make sure your phone is running the latest software version. Go to Settings > About phone > System update to check for any available updates. If an update is available, download and install it.
If none of these steps resolve the issue, it is recommended to bring your phone to an authorized Vivo service center for further assistance. They will be able to diagnose the problem and provide a solution.
