Memory allocation has been all the craze lately. Take the vivo X60 Pro+, for example. It gives you the option to extend the memory by allocating storage so you gain extra 3GB of RAM. Well, it seems that Xiaomi is working on such a feature of its own too.
A tipster found buried deep in MIUI 12’s source code a feature named “Memory extension”. It does what the vivo X60 Pro+ does but it’s limited to 1GB only. It requires some tinkering before you can unlock the toggle, though.
