The Archos Smart Home Tablet may have come with a screen protector covering the screen, not always visible at first sight. It can retain dirt and fingerprints but can also disturb your touchscreen experience. 

To check if a protective film cover on your screen, look at one of the corner of your ARCHOS Smart Home Tablet if you can see a mark and scratch slightly with your nail. The protective film can be easily removed once the corner is unsticked.
