Smart Diagnosis

Smart Diagnosis is a support tool built to diagnose and resolve customers' technical issues. It easily checks the device’s status, locates any issues, and provides with an official version of the troubleshooting method and tailored software and setting solutions.


One-click detection to diagnose phone problems

It provides full detection coverage, such as hardware, software, calls, network connection, charging, system performance, and more. The detection process is short, quick, and accurate.
