Our benchmark apps are not supported on devices running custom ROMs. You may experience crashes, graphical glitches, and other problems. You should contact the ROM developer for help resolving these issues.
Our mobile apps read the manufacturer and model information supplied by the OS. Unfortunately, this information is not available in many custom ROMs, which means the app cannot tell what kind of hardware you have.
The app will show incorrect information if your custom ROM has a fake device string. This is common with lookalike phones that appear to be a well-known model but may have different hardware inside. If it's not a genuine device, the app most likely won't be able to identify it at all.
In all of these cases, however, your benchmark score is still valid. The benchmark does not know which device you are using and the performance measured is still accurate for the actual hardware.
