{UPDATED} and now for Q too. Better Performance and battery for a20 stock Pie - Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot

#This is for android Pie..
After reading many topics abut the build.prop file and abut the VM and after many testing. finally i got somthing usefull in performance and battery friendly :fingers-crossed:.
Tested on s6 update and i think it will work with all update.the build.prop attached down here.
# how to:
- unzip the file and open the build.prop with any text editor.
- select all the text and copy.
- use mix explorer and go to system\vendor.
- open system\vendor\build.prop.
- select all text. Delete.
- now after that past what you copy before.
- press save. Then reboot to recovery.
- go to wipe..advanced wipe..and wipe both cach.
- reboot to system.
Post your results after testing:good:
Edit: some people get a problem when copy the all text in rhe bulid.prop file because the diffrent of the model and update.so i will post only the change i made in the codes then it will works with all models and updates and replace the numbers as the following:
Open system\vendor\build.prop
..and change the codes like this
dalvik.vm.heapgrowthlimit=160m
dalvik.vm.heapsize=512m
dalvik.vm.heaptargetutilization=0.625
Then scroll down and change like this
ro.config.dha_cached_min=2
ro.config.dha_cached_max=5
ro.config.dha_empty_min=4
ro.config.dha_empty_init=8
ro.config.dha_empty_max=15
ro.cfg.dha_cached_min=6
ro.cfg.dha_cached_max=15
ro.cfg.dha_empty_min=4
ro.cfg.dha_empty_init=17
ro.cfg.dha_empty_max=24
Thats it...now press save. Then reboot to recovery.
- go to wipe..advanced wipe..and wipe both cach.
- reboot to system.
Post the results please.good luck

@hooooossamq I had some problems due to my phone being another model (SM-A205G), luckily I had a backup from the original file to restore. In this case I cannot vote =)

I make the vote to know if its work with all galaxy a20 .and if any one have any idea and edite the numbers of this build.prop file to make it better it will be great.but must be tested by the editor before sharing it here.
good luck for all...

@hooooossamq I got a bootloop for the first time I installed and then I restored the original build.prop and that didn't solve the problem, in the end I have to flash the whole firmware again. It's not your fault though. I guess the problem was caused by our phones being different, my bootloader is 5, yours is 6, my model is SM-A205G and yours is the F variant
