Make SU6 more snappy by adjusting resolution and DPI (no root needed)

[Guest spaceboy_100]

I managed to make my Smart Ultra 6 feel a bit more snappy simply by adjusting the resolution and DPI.

The nice thing about this is that it doesn't require root - just an ADB connection. Here is how I did it:

 

1. Enable USB debugging in the developer options on the device.

 

2. Install ADB on your PC - I used the lifehacker guide to install it on my Linux machine with no problems.

 

3.  Connect over ADB using the USB cable

 

4. Open a terminal in and run:

adb shell wm size 768x1366 && adb shell wm density 360 && adb reboot

or

adb shell wm size 900x1600 && adb shell wm density 420 && adb reboot

 

The phone will reboot in the lower resolution. This will survive further reboots, but I think a factory reset will clear it.

Obviously you will be trading some sharpness for speed, but to me this is worth it - even the lower resolution option is higher res than the iPhone 6.

 

To reset back to default run:

adb shell wm size reset && adb reboot

 

I apologise if this has already been posted. Just wanted to share as I thought it might be useful to someone else.

B-But you bought a full HD phone to make it not full HD

So, whatever command I run, it just doesn't run in fullscreen, after the reboot. What am I doing wrong?

what do you mean it doesn't run in fullscreen?

I mean it isn't properly scaled. If I set it to 720p, it literally uses only 1280x720 of the pixels instead of scaling the image up for all the screen, so it shows the image in only a quarter of the screen. The rest is black. However, it still works as if it was fullscreen (i.e. touch inputs go to the place they should).

I had/have the exact same problem. It seems to solve itself after being rebooted and having the screen auto-rotate a couple of times.
