LG G4 Resolution and DPI - For battery and performance improvement - ROOT REQUIRED

For People that have very little battery life and feel phone is slow or just want to get a low DPI (lower than 540) to work on phone in general here is the trick
1. Go to terminal emulator
2.Type:
3. Su
4. wm size 1080x1920
5. wm density 440(or any dpi you want)
6. Install Xposed download module called App Settings
7. Change the dpi of lg apps to 540 or higher
8. for the phone app you have to change the Contacts app also.
9. Now to make the phone to work to receive calls and to dial a call you need Tasker app (its a paid app unfortunately...)
10. Go to Tasker
11. go to the tasks tab
12. create two new tasks
13. On the first task: Name it DPI:540
14. add new action
15. click on code then on Run Shell
16. on command type wm density 540
17. check the box Use Root
18. The second task do the same thing except the command: wm density XXX (X represents any dpi you want).
The rest to make it easier watch the video:
