My uncle had an issue the other day and phoned me to help, it was some full screen adware thing and it looks like he clicked on some antivirus advert which was the start of all this nonsense.Doesn't matter, the point is:
All of these phones have those "free" games with the adverts installed and being used. Those adverts are used to installed other crap which leads to the issue.
- Pop‑up ads that take over the entire screen and cannot be dismissed.
- The power button becomes blocked so you cannot switch off the phone.
- The phone takes control of itself. If you try to open Settings, it immediately closes.
- You cannot close recent apps, and similar issues.
Pretty ironic but you can see why the old people are falling for it.
I suppose you can install Family Link as it does let you manage what is installed on the device.
The problem is that it has its own overheads so on those older\cheaper phones it will slow things down.
