Those three apps are often installed by default in the most of android systems. They can be easily removed with adb. But what they do exactly? What type of data they collect and send online?
I don’t know what they exactly do, but meta services app is constantly trying to connect to Facebook. I’ve isolated it with rethinkDNS so it can’t use internet connection.
You can uninstall with adb
U need universal android debloater it works via adb and u can delete apps temporarily until factory reset,u can also delete a lot other Chinese spyware like msa daemon which sending tons of data from your phone.https://github.com/0x192/universal-android-debloater And yeah this apps always come preinstalled with any xiaomi phone for Facebook surveillance :)
I know. You can also remove the apps only with adb, this is not the answer. The answer is what actually those apps do exactly?
Well it’s require reverse engineer them,but knowing Facebook don’t expect anything good.
