Missing storage space in Android 7.0 Where did all the missing space go? I've deleted most of my apps, but no matter how much I get rid of it keeps saying I'm almost out. The stuff I have accounts for 3.5 GB-ish, but there's lots that seems to have disappeared. The version is Android 7.0; the phone is a Samsung Galaxy S5.

What's going wrong here?
Never seen this before!
Anyways here is the steps i would do:

1. If you are sure that the 15.9/16GB is wrong, e.g you know you haven't got that many apps/videos, then proceed to step 3.

2. If you know you have got like more than 50 apps or really many videos, take some time and delete videos/apps (of course images, otger files too) that take much storage.

3. Go to Setting > Device Mainteance and then clean everything you can (optimize the phone)

4. If that doesn't work go to like a phone reparator and check what they can do.
