your phone's storage is full. the reason it only shows 157mb in windows explorer is that android is fairly locked down (not as much as ios) and a lot of what's on it is hidden or functionally non-visible by default.

if you can use your phone, just delete some apps to free up enough where it's not constantly throwing errors/experiencing horrible performance, then use the storage manager in settings to determine where most of your storage is being eaten up and proceed from there.

if you can't manage that because it's too fucked, but you can still get to settings, then enable developer mode (look up how to do this on your phone, it's usually very easy), enable usb debugging, and use adb to delete some apps instead.

turns out I had 5 GBs cache on my browser... I cleaned that up, but there still should be more to free. I will look on those things with the storage manager that I have never used. thanks anon
