There's an app called "Software Update" (obviously a system app) in my device. What it does is give me ads that I don't want and install apps like Amazon, Clean master that I don't use. It do these things without my permission. Because of this, I have to daily delete whatever stuff they install in my device. I do not want to root my device. The problem is that I can't disable this app. There are other system apps in my device that I don't want and I could disable them. But this, there's a disable button, but it's not clickable. I know I can't delete it without rooting, so is there any want to disable this unwanted app? I tried using freeware firewall apps to block it from the internet . But those apps use pretty much ram.
Any ideas to disable it? Directly or indirectly?
