I got a s21 plus with 128gb at the time it was 50 more for a 256gb version. I thought I would never need that much space. For the past year or so I have been near the max and constantly have to move files around with my computer. I regret not picking the higher storage option. I like my phone but the only way I’m getting more storage is with a different phone.
Don’t do what I did. Pay the extra money for more ram… And get more storage if that’s an option also.
You can’t turn off auto updates on Samsung phones.
