I tried to get a low-budget smartphone and we found this one. I will get it by shipment.
It seems that it uses Android GO for the operating system.
What can I do to degoogle and debloat it?
What software can I use to back up the entire Nandroid directly into a computer if I ever manage to mess up?
Degoogle, as in deleting all Google Apps efficiently, including their libraries, and replacing them with other, non-intrusive alternatives.
Debloat, as in deleting any other unwanted apps such as Samsung Apps and MediaTek Apps.
