By the way, the other tablet I'm using (Nexus 7/Android 5.0.2) seems to be fine so far, probably because it's the latest OS with Android bugs fixed.

After doing some research, I found that most of the 8GB internal memory (about 7.5GB) was taken up by thumbnail files (.thumbnails), and the direct cause was that there was almost no free space left.

(Android or app bug) Therefore, today I would like to report that I succeeded in getting out of this predicament using the method below. If you are having trouble with a similar phenomenon, why not try it?
