To be honest i tried creating a game booster app and i set it to boost ram the ram boosting i mean is it allocate the part of your ram exclusive to that game without crashing the O.S of your phone.
And than i boosted the cpu by allocating the resources to the game without that much heat and than after that i added gpu booster it automatically allocate all resources to the game giving you the best posible resources ever.
Lastly i precache the game in the internal memory that will be frequently accessed to the bus internal only a small chunk so it can load much faster but i added a.i to control the temperature
This app i created i tried this to his 1 gb ram phone with android 10 he always cry because he can’t buy powerful phone to play the call of duty mobile when he play it it is as smooth as a silk.
The booster you seen in the playstore is a scam only the paid one is real or that i created with my whole hearth.
