Screen protection - ARMR200 film
3m produce a product designed for touch screens called ARMR200. It can be purchaced from their reseller(s). e.g., disagu.
As the neo 1973 and neo freerunner smartphone screen both are the same size ["43mm x 58mm"] this process applies to both. Please note my measurements differ slightly as I measured the screen when disassembled and it is 45mm x 61mm, although there is a white "tape" around this so the film maybe can be slightly larger and still work ok. I will report back as I test it.
I purchaced the 14.1" wide screen protector for the reason that from my calculations I could get the most screen protectors from this size with least waste. It gives 20 protectors when cut as I describe. I wanted the film to extend under the outer case so no foreign matter e.g., dust, could get under it. 305mm / 5 = 61mm, 190mm / 4 = 47.5mm.
1. [the case].
2. Clean the screen. A dry lens tissue works ok. Alcohol may well damage the screen!
3. Mark and cut the film to size. A scalpel and metal straight edge give a good result but a pair of scissors may work ok. Place the scalpel on the mark and bring the straight edge to it, this is more accurate method of cutting with a knife. Two or three passes are necessary to cut the film. (The scalpel blade if sharpened on a finishing stone will make this easier.)
4. Peel back the protective cover from the one corner of the adhesive side (be careful not to touch the adhesive, as it might leave a mark)
5 Double check the screen is still free of dust and grease etc.
5. Align the film and press on it while slowly peeling off the adhesive. Make sure there are no bubbles trapped. If there are lift it off slowly back to the bubble and reapply.
6. As can be seen in the photos the film didn't stick at the bottom of the screen. I will try to fix this in the next day or so.
Pictures to follow.
The film has a matt finish which looks differnet to the glossy original and the film feels different to the screen. So far it functions fine.
