Below we provide you 3 simple troubleshooting to check before you send your phone device for repair.
1. Charge your device
Use the original ASUS AC power adapter and USB cable to charge your device for 15 minutes.
Note: We suggest you directly charge your device with AC adapter , which would be faster than charging by the USB port of a PC.
2. Update the firmware
Update the firmware to the latest version.
Notes：Do not run the firmware update when the battery power is less than 15%. Please plug-in the AC power adapter to charge the device before updating the firmware.
3. Do the factory reset
Reset your device to the factory settings
1. Doing a factory reset will remove/delete all the data stored in your ZenFone.
2. Please plug-in the device with AC adapter or make sure the battery power is more than 15% when doing a factory reset.
