Yes, I am using swap. In Linux, it is used for hibernation, and when 
there is memory pressure; my mini server uses it.

I looked up "memory" on mine, which is not Samsung but Motorola, and 
there is no memory entry in the config. I found "performance" (under 
system), and on this I saw "intelligent application start (enabled)" and 
"RAM improvement" (disabled). The later says "if there is enough 
storage, use some to enlarge the RAM".

   Device memory: 6GB
   memory expansion 1.5GB (greyed out)

This must be swap. There is a switch to enable it.

It doesn't say how much ram is in use, except with graphic bar; I 
estimate 5 GB are in use.


So I search instead for the word "RAM". Size of ram is found under 
"about the phone", "hardware info". Again, it doesn't say how much is in 
use. It also mentions there is 128 GB of ROM.


Funny the different names used across different brands. Of course, my 
phone is in Spanish, but even so it is not the same menus.



On the storage chapter, my phone has 128 GB, of which the beast is 
applications (61 GB). Photos are just 11 GB, videos 6.2 GB. I have two 
large applications: OsmAnd+ (17.97 GB) and Pocket Casts (15.41GB). The 
later is a surprise. To my knowledge I am subscribed to only one 
podcast, which I have configured so save automatically, so that I can 
listen with no network. But I had no idea they were taking so much space.

Wasap is just 2.91 GB.


Ah... pocketcasts is also storing a second podcast, one of "books in one 
hour" since May 2022 (one per week); older ones are listed, not stored. 
I have now disabled auto download of this one.
