For those of you looking to try these tweaks:
Disabling Android Go mode (enables split-screen, PIP, multiple users): ro.config.low_ram is a parameter in the build.prop file. Here's a
guide to editing build.prop using ADB on a PC.
Editing the zram size: You need to edit the file fstab.qcom file in the path /system/vendor/etc/. The method is essentially the same as editing build.prop.
Find the line that reads:
Code:
/dev/block/zram0 none swap defaults zramsize=25%,max_comp_streams=4,swapprio=10,notrim
Replace "defaults zramsize=25%,max_comp_streams=4,swapprio=10,notrim" with " defaults zramsize=50%,max_comp_streams=4".
I've made both of these changes successfully, although I can't tell if the zram change actually has any effect on performance. Would be interested to hear what others are seeing.
