You need to be careful when downloading APK files so as not to infect your device with viruses. I have been using the
Minecraft APK site for a long time. This is a trusted resource where files are updated regularly, and there are also installation instructions. It is important to enable the option to install from unknown sources in the phone settings before installing. After downloading, I always recommend checking the file through an antivirus. The site I mentioned has a detailed description of each version, which helps you choose the right one. Do not download files from suspicious sites where there is no information about the developers or user reviews. It is better to spend a little time checking than to restore the phone later.
