Good evening, I opened my mobile phone today,And I saw something strange, where I was at Internet the screen started to close, the cell phone started to turn off, I tried to enter the security and then it led me to the home screen or to other applications, after a long time I managed to enter In security, there it showed me that I did not have a virus but for a long time it continued to be the same

Sorry for my english
Please tell me what to do... Phone(xiaomi redmi note 7)
