My wife is butting up against the limits of her 32 GB phone. It appears to be mostly through apps and not music and videos. Weirdly, when I looked at her app list, some of them displayed a bigger amount of memory used for a second, then showed a lower figure.
It might have shown the cached memory amount (from the last time it was checked), and then updated to the current result.
Get that weak shit off my track
I've also run into an issue, only with my wife's phone, where the mail app would end up with a runaway cache directory. The space used by that directory wouldn't show up as being used by the app, so there was just this phantom missing space on the phone. I'll have to see if I can find my notes on how I found that.
I had a similar issue with my Note 3. Something to do with how the underlying Linux code reports memory in certain block sizes, and the overlapping Android OS reported it differently and over time a huge gap would be created. Android would be over-reporting the usage when in reality the actual size on disk was much lower.
I have a bad feeling about this random release of 128 and 256GB versions of the S9 that Samsung is doing. I'm worried they're testing the waters to get rid of the SD card slot (again).
I hope not. Then it will be time to jump ship once again.
One of my (many) USB chargers just turned into a USB discharger.
I got an S9 64. It's awesome.
