I Deleted files on internal storage but free space remains the same I noticed I had 623MB free in my internal storage so I connected my Android to my Laptop and navigated to the Thumbnails folder which had lot of files and was big in size. I selected all files and deleted them, it was about 300MB. Now when I read the available internal memory space, it reads 623MB...

What happened here? the files are no longer there but for some reason Android is not reflecting the increased available memory..

any clues?

Thank you!

Sometimes it may not reflect until restart. Moreover, thumbnails would be recreated once you open the images again. Perform a restart or reboot.
