Some months before I have purchased Samsung mobile with 3 GB RAM, initially it was working good as expected but after some time it’s start lagging & responding very slow. I tried uninstalling application & daily cleaning up the memory but that is also not helpful.
Then I start digging some of the options & found below 3 options in “Developer Tools” in Android that can be disable to boost up the speed.
Goto — Settings —- Developer Options (if it’s not enable then there are lot of videos / blogs for the same or easy way to enable “Tap 7 times on your Build Version” under details & option will be now visible.)
Please Note – Don’t Play with Developer options, it may damage your phone. Better to hide the same again after doing above steps.
After disabling above 3 options start using your phone normally & now you can see performance the mobile is now change & responding quickly as new 🙂
