To stop your UMX phone from loading and opening "phonrp" or from downloading to come on, you can try a few troubleshooting steps. First, try restarting your phone and see if that resolves the issue. If not, you can try clearing the cache of the specific app causing the problem or perform a factory reset on your phone if the issue persists. It may also be helpful to contact UMX support or check their online forums for specific instructions related to your UMX phone model.
