APP FOR 4.3+ ONLY

I put together this app to easily switch between 3 resolution modes. Optionally hit the backup button to copy to /sdcard/tmp

For each mode it just runs a script like this.

#!/system/bin/sh
wm size 1920x1200
wm density 240
# mounting system as rw
mount -o remount,rw /system
export DENSITY=`cat /system/build.prop|grep ro.sf.lcd_density`
sed -i s/$DENSITY/ro.sf.lcd_density=240/g /system/build.prop
mount -o remount,ro /system

its replaces the line in the build.prop so things like the keyboard scale properly. Let me know if it doesnt work. Just hit the reboot button after you change it. USE AT YOUR OWN RISK.

ya DPI doesnt change, it stays at 240, which will be look big for 1600P or too small for 720P

I'm pretty sure wm ignores the build.prop DPI value. It does on mine anyway. It saves its setting to dB in /data/data somewhere. com.android.preferences/ inside that I think.

im running cm11 4.4.2 though atm.
It might be that its targeting 4.4.2.
For me that build.prop value has to be changed. Or something else does.
There might be a problem with that apk...ill look at it again.
ill put the source up so you can fix it up and feel free to include it in your rom as a bells and whistles option haha

OK it might be that certain apks use the build.prop to calculate the screen size? Let me look at the source.

Try locking the DPI to 160 once the user gets down to 1280. The way I calculate the DPI is take the length of the screen and divide by 8.

1280 is 160
1600 is 200
1920 is 240
2560 is 320

Etc ;)

OK I added backup and restore to the app. Seems to be working.

Backup does this:
#!/system/bin/sh
mkdir -p /sdcard/tmp
cp -f /system/build.prop /sdcard/tmp

Restore does this:
#!/system/bin/sh
wm size 2560x1600
wm density 320
mount -o remount,rw /system
cp -f /sdcard/tmp/build.prop /system/
mount -o remount,ro /system

Let me know if that's not correct

That's great! I think restore should do this:

wm size reset
wm density reset

;)

I'm using cm11. It works well. I haven't used it with cromi but it look like it should work fine. I'm using thumb keyboard and it scales fine. The game shadowrun actually looks bigger at the lower resolution. More playable. Characters were too small.

On the nexus 7 2012 I have, the wm command works. You can just modify the app to what you need. What. Itll do if you try to set it to 2560*1600 320 I don't know. If you want to modify the app you just need to:

1. Add a script to the raw folder like the others
2. Add a button to the xml layout
3. Set the button to launch the script it in the apps main activity.
