Hi there, this is for sure a major issue that people need to be aware of.
I would also suggest not to download everything on your smartphone. Especially APK files, there is a very dangerous malware named Gustuff going on and spreading quite fast. You can see t
this article.
I do use 3 smartphones (2 of my old ones):
- my main smartphone that i use for personnal stuff
- the 2nd one for only google auth (2FA)
- the 3rd for airdrops Apps
Another usefull tip, if you are doing airdrops, is not to use your same registered address on trusted exchanges.
