Re-apply official fairphone screen protector?

I applied the official fairphone privacy screen projector. After finding out the next day the alignment was slightly off, I removed the screen projector and re-applied with the correct alignment, how-ever … one corner does not ‘stick’ anymore.

I used a (plastic) spludger to lift one corner to start ‘peeling’ off the screen projector, but this corner does not ‘stick’ anymore. I guess the ‘glue’ used has been removed somehow. Maybe I should have used a suction-device or maybe something totally different (or should not have removed it at all).

Since Fairphone is all about repairing stuff, I was wondering if I could repair the screen projector as well? I read online their are multiple glue types used to ‘cure’ the projector to the screen, how-ever I cannot find out which one is used for the official fairphone screen projector.

It feels a complete waste to throw away a almost new screen projector. Does anybody know a procedure to repair the screen projector, allowing it to re-apply again?

How big is the corner that isn’t sticking anymore? If the rest still sticks correctly, I wouldn’t bother. I have a family member whose screen protector has a corner who hasn’t been sticking anymore for one or two years and it has never bothered him anyhow.

I guess you shouldn’t really have tried to remove it after one day. But a suction cup wouldn’t have been efficient anyway.

Roughly 5x5 mm.

Good to hear it does not effect overall functionality. It does bother me just enough, wanting me to fix it :slight_smile:

It really doesn’t seem serious to me, would you mind sending a photo of it?

Well the best solution for me not to waste a screen protector and not to waste time/glue to find a solution would just be forgetting about it :wink: Is it really bothering you by hiding a part of the screen or by stoppng touch?

It does not stop functionality, I am just curious in how-to do it better next time and learn a bit on the mechanics of the screen projector used in the process.

From the looks of it the glue used is not the ‘permanent’ type. No Liquid Optical Clear Adhesive (LORA), since it does not require curing with a UV light and can be removed without issues. Seems to be a Optically Clear Adhesives (OCA) film like 3M 8212, ARcare 92524 or similar is used to adhesive removable base, something in the line of:

Which makes be believe I damaged part of this film in the corner by improper usage of removal tools (read: trying to remove it at all).

I have played around and made a little hack which somehow fixes it. Using a wooden toothpick as tool. Slightly (1mm) lifting the corner in a dust free environment. Next I taken a few pieces of 3M scotch magic tape to transfer some ‘stickiness’ to the screen (repeat the process a few times). After this ‘sticky’ transfers I lowered the screen again. This allowed the corner to ‘almost’ stick again.

I did some further inspection with a microscope camera, after doing the hack, and this seems to support the hypothesis of damage of the adhesive film by using improper tools:

Not sure how long the hack it will last, but it is the best I can make of it. And will learn to live with it :wink:

PS: Would be great of Fairphone has a option during ordering to pre-apply the screen protector. Applying a screen protector in a factory based setting would make a ‘perfect fit’ possible :slight_smile:
