Before you give me any advice, let me explain the problem and what I am doing about it. I bought my Galaxy four years ago, and it has 16 GB of internal memory. All was well for a couple of years, and then I decided I needed to get some extra memory, so I bought a micro SD card, also with 16 GB of memory. I started by putting the photos from the phone’s camera on it, and later the ones from WhatsApp. Again all was well for a while, but in the past six months or so I have been having trouble again. The My Files app tells me I am using 15.32 GB of the internal 16 GB.
Every morning I check my phone’s apps for updates, and there is usually at least one. Some of the updates can be large, so some fail to install because of lack of memory. I suspect the apps must now be larger than they were a few years ago. I have tried moving some apps to the SD card, but only a few have allowed that. I have also looked into uninstalling the apps I don’t use, but again many don’t give me that option. I can sometimes uninstall updates, or disable the app, if that helps. I am now reduced to clearing caches. Incidentally I’ve noticed that Signal occasionally downloads a backup file, which is 116 MB. I assume I only need one backup file, so I’ve started deleting old ones.
Having (I hope) read all that, do you have any suggestions?
