Motorola Moto E 2015 4G/LTE, aka that phone:

Zram is being used in bq E5 which also have 1 GB of RAM. It does make the phone faster and smoother.

@kugiigi and how it could be implemented on surnia?

@impreza233 probably first kernel config https://github.com/ubports/kernel_vegetahd/blob/master/mediatek/config/krillin/autoconfig/kconfig/project#L1947 then check kernel log to see whether ut picks this up right away

@doniks thanks I will take this on account.

@impreza233 Looking forward to hear how this goes!

@doniks myself and a fellow (@bartbart2003 ) have tested that on config, but it seems not working at this moment

mhm. so you did enable in the kernel config and it has rebuilt and booted successfully? Anything visible in kernel log?

I have never used zram before, but from quick research it looks as if it is all about creating a swap space (in compressed ram). Do you have a swap device now? Is it used (swapon -s)?

@doniks it has booted successfully, but we have not seem any indication on kernel log. We will test that command.
