I got my Linx 10 tablet today and there is a clear plastic sheet on the screen with a sticker in the corner. The sticker says "2. Please peel off this mask AFTER application completed".

Can someone tell me what this means exactly? Do I have to do something before I peel off the cover and use the tablet?

Have you turned it on yet? Maybe the 'application' is a self test?

That's what I would do, too. Keep it on, turn it on. If it works do as you like. If it does not it's in the original condition.

Don't peel it off...
I had one & assumed there was another cover underneath & that was just the top sheet
It's not.. if you peel it, the screen will be bare.
just remove the paper tag

The screen is supposed to be like that. The cover with tag is just a protective layer against dust and grease etc. You can buy replacements if this is what you require. Personally I prefer to use it without.

I peeled the little label off but left the screen cover and it works fine.
