How to enable zramfs in android...

[Corey Sheldon]

works on linux desktop may also work on android:


cat /proc/swaps: (should readout)
/dev/block/zram0                 52M (as kb readout most likely)

if it shows a different slice path (/dev/zram0 for example) use swapon
/that/mapping/path

also try swapon -p 100 -v -a /dev/block/zram0  as this adds the following
flags to  activate ALL visible swaps and add a verbose function to create
readout that may help in debuging issue
