You need to install a "Root Firewall" in your mobile by which you can control the Internet connectivity of all apps (including system apps). They also offer to block only Data connection and not wifi connection for a specific app. The app I'm using is "AFWall+" (free). Note: This type of apps only works on Rooted android phones.

Short answer: You can, but you shouldn't. Install a custom ROM instead. Long answer: Some features in your stock ROM may be dependant on that ROM's Settings app, because it might contain some preferences that affect them. Your Settings app may be missing some Lollipop settings simply because the ROM doesn't support them. You can try to install the AOSP ...

If you didn't have the requirement of being able to access the settings (the settings app is part of the launcher in some ROMs), this would probably be easier.

I had this problem recently and solved it by removing old saved networks in the WiFi settings. I found that there were a huge number of networks with names that were strings of letters and numbers. To remove saved networks open 'Settings' and choose 'Wi-Fi' (and wait for it to load). From the 3-dot menu choose 'Saved networks'. You should see a list of ...

Sorry for the post on an old message, but this seems to be one of the higher ranking Google results for this and I still haven't found much of an answer elsewhere. Good news and bad news: good news, Izzy's right; bad news, it probably won't help much. I found my open tab info under /data/data/com.android.chrome/app_tabs/0. But they don't seem to be stored ...
