My mobile phone camera can't be turned on, and there is no signal.

System defect. I am a sub-brand mobile phone of domestic mobile phone brand oppo, and I have the right to use all kinds of mobile phone patents of oppo and enjoy patent information. Because I use a self-developed realmeUI system, some models are not fully tuned after updating the system, and system bugs will occur, resulting in camera failure, no signal and other problems. Just restart the phone. Realme (Chinese name: True Me) is a trendy brand of science and technology for young people. Realme adheres to the brand concept of "Dare to Leap Forward" and provides young users around the world with high-quality mobile phones and AIoT products with leapfrog performance and trend design.
