I started getting alerts about exceeding the maximum storage space on my Android.

When I used  apps to clean my files I  kept seeing a ton of files in a folder called .thumbnails.

Did a little research and saw that Android has a bug which affects the hidden .thumbnails folder.

I followed these instructions:

You basically delete the file(s) and add a new dummy file in its place.

I got 5gb more space now.

Sweet!
