Another example from that era: Commodore 64, 64KB of memory, but when you
turn it on, it says "Commodore 64 Basic V2 38911 Basic Bytes Free". As
above, you could get to some of the additional memory through paging, but
I'm sure it was beyond most people at the time.

Hi Paul,

Along those lines, it's currently beyond my capabilities, but, I may have
to root the 4GB phone (not that I really know what that entails) in order
to free up some of the 3.4 GB that is currently being used by the T-Mobile
Android 4.1.2, P76920h, LG Optimus L9 smartphone (model LG-P769).

Googling, I see that the rooting process is risky; but, if I faithfully
follow it, do you have any idea of what I can reasonably expect by way
of gains?

That is, can I only hope to free up 10 MB of memory? 20MB? 100MB? 1GB?

QUESTION:
If I root the phone, what can I reasonably expect to free up?

The same site has a forum for the L9. People there can tell you
whatever you want to know.
