[Q] Can't install apps when Tab S 10.5 gets to about 500MB remaining topic

Hi all,

I have a Galaxy S 10.5 (16GB) that I picked up in September of 2014. I love the thing but it's showing a weird issue. Any time I hit 500MB storage remaining, Google Play Store will no longer update apps. It gives me an insufficient storage notification. I can go in and clear the cache and everything is great - until I get to 500MB remaining again. Then I have to find more space again.

I've had a 64GB SD card installed in the device since I purchased it. I store music there and move apps that support it to the memory card. I was hoping that having the SD card would make the (insufficient) 16GB of storage liveable. It hasn't and the 500MB has only made it more challenging.

Has anyone seen this before and/or have any ideas what might be going on here.

Thanks!
