added link to comment related to how AOSP Go optimizations increase CPU usage, so might be bad.

| /data partition | 4 GB | It might also be possible to use external storage for that |

Source code and configuration¶
Android can be configured to use less hardware resources. Here are some links on the topic:
- Low RAM switch - ro.config.low_ram
- Links to Android Go Optimizations that exist for AOSP 8 and AOSP 9 (This might be a bad trade off if it optimizes RAM at the expense of CPU power since the CPU is used to render graphics)
