Not a samsung S21 user but for me try using the maximum. But it will heat you're phone as they said under the (Maximum text) so it's you're choice or if you want a balanced and normal processing try using the Optimized. And just read the article under there. So that you will understand every detail. Just correct me if am wrong hehehe
Hey there! As mentioned by your fellow members here, processing speed may be set upon the usage of your device. The more apps you REGULARLY use, the faster processing speed you need. It's like using a BLENDER, the more you put inside to shred, the more power the blender needs to get the job done! Hope this helps! 😊
