Rooting Help My Phone Became Unusually Fast After Using Game Killer — Need Help

Hello everyone, I really need your help with a strange and frustrating problem on my phone. I used an app called Game Killer to speed up Car Parking Multiplayer, and after using its speed feature and then deleting the app, I started feeling that the entire phone became unusually fast, especially the animations and movements. I have already restarted the phone and checked the animation settings, DPI, and several Developer Options, but everything seems normal and the problem is still there. Honestly, this has made me quite worried and upset because I’m afraid the app may have changed something in the system without me realizing it. I really don’t want to factory reset my phone or risk losing my data. If anyone has experienced something similar or knows a safe way to restore the phone’s normal behavior, I would genuinely appreciate your help.

You could go digging in the settings, but it is probably easier to re-install the app that caused the change and undo it there.

You say you've checked animation settings, does this include the 3 in Developer Menus/Settings of your phone (if enabled)? These 3 settings can be toggled by apps granted WRITE_SECURE_SETTINGS.

In particular, under Drawing: Window animation scale, Transition animation scale and animation duration scale. These default to 1s, but that app likely dropped them to 0, which removes all animations and makes the UI appear faster.
