My Developer Options Settings Recommendations and What I am Using
Apart from checking Memory activities to know which apps are hogging my memory, I am using Developer option to also:
- Switch which app to start during boot, I remove apps which are not important to start during booting.
- Switch USB configuration between charging only (if I am charging my device on someone else’s computer or houses) and MTP.
- Activate advance restart to go direct into Recovery mode. Easy for me to install a new custom ROM.
- Enable debugging, allowing ADB connection, this is also make it easier for me to install a new custom ROM from computer.
- Tweak Android speed, make it faster by reducing the animation. Do check here on my other article showing in detail how to use Developer Options to tweak your slow Android to be much more faster – all without rooting.
