There is no guarantee that third-party applications from unknown sources will contain some charging plug-ins or malicious viruses, which may damage mobile phone components or cause you economic losses. I suggest you download the same type of software from the "Software Store" APP. The "Software Store" APP carries out all-round and in-depth automatic detection and manual detection of each application, and strictly controls the whole process of "review > shelf > download > installation > update > management > feedback" of the software, so that you can use it with confidence.
Tips:
① You can also directly search for "foreign application" or "installing unknown application" in the search bar at the top of mobile phone settings, check the opening of applications, close unnecessary installation channels, and reduce the risk of software installation.
② you can use the "mobile phone housekeeper" APP > virus scanning to kill and optimize the virus according to the prompts.
