What is zram compression?
On Android, there is no swap! In ZRAM unnecessary storage resources are compressed and then moved to a reserved area in the fixed RAM (ZRAM). So a kind of swap in memory. This Ram is more free because the data then only about 1/4 of the former storage requirements have.
How do you change zram size?
To permanently change the size, you have to adapt the init script, where the swap files are created. Be aware, that this file may be overridden by future system updates. This is persistent across reboots and seems to be the recommended way of controlling zram. You need to change to “root” to do this.
