!!! WARNING !!!

Texdroid DPI allows to easily change DPI settings on rooted devices.
This can cause your device to get in bootloop.

Make a backup before using it.

In case of bootloop please replace /system/build.prop with /data/data/com.texdroider.texdroider_dpi/files/backup/build.prop using adb or restore a rom backup.

This should solve your issue.
