I was puzzled about the appearance of a new folder on my phone called joox_for_third . There were many assumptions, the first was a virus, but the antivirus software did not find anything, the next step was a more thorough search and as it turned out, it was not in vain, it turns out that the latest Mi Music updates are to blame . it seems it's time to be puzzled by the fact that some regular applications are no longer installed, since I still don't use them.
