How to identify the best iPhone screen protector?

This article is intended to reveal ways to identify the best iPhone screen protector. It took our engineer years of research to produce excellent quality protectors. All following points are summarized based on real experiments in our R&D center. We aim to provide our customers a complete and useful guild in buying the best iPhone screen protectors.

There are a few areas to look into in order to identify the best iPhone protector:

1. Durability and protection: The best iPhone screen protectors are made from durable material that will protect your screen from more than just day-to-day bumps and scratches. Whether the screen protector is thick or thin, it should be hard and scratch-proof. It should also resist fingerprints and germs.

2. Design: The screen protector is designed in such a way that it feels smooth under your finger, responds to your touch and doesn’t leave you feeling like your finger is floating above the screen – regardless of how thick it is. It also should also come with a cleaning cloth to help you get all the fingerprints, oil and dust off your screen before you apply the iPhone screen protector.

3. Installation: The best protectors go on easily without trapping air bubbles or requiring constant re-positioning. If you do need to adjust your protector, it should move easily so that you don’t have to throw it away if you don’t get it right the first time. If you want to remove the protector altogether, it shouldn’t leave sticky adhesive residue on your screen.

4. Warranty & Support: The good companies in this industry back their products with generous return policies and money-back guarantees. The best ones like YOSH provide lifetime warranties.


In order to further classify how we approach to the finest quality screen protectors, we performed several experiments. They are intuitive and precisely expressed features of YOSH screen protectors.

Experiment one: Anti scratch/abrasion

Brief introduction:
YOSH tempered glass screen protector and screen protectors purchased from other brands and tested separately under same experimental conditions to ascertain its strength and quality. They are tested against significant friction produced by high speed rub to ensure that they are of high quality.

Experiment instrument:
YOSH Tempered glass screen protector;
Screen protectors purchased from other brands;
Scratch test equipment.

Experiment process:
1: Set the test equipment to perform 10 units (1000 times per unit) of high speed movement to produce significant friction.
2: Insert YOSH Tempered glass screen protector for test, observe and record;
3: Insert the other screen protector for test under the same experimental condition, observe and record.

Experiment results:

After 3 units of rub, the ordinary screen protector cracked completely but the YOSH tempered glass screen protectors suffered minor scratches that are almost invisible to the eyes. In the course of the experiment, the YOSH Tempered glass screen protector withstood up to 9 units of rub while the other screen protectors could only withstand 3. This experiment shows that the YOSH Tempered glass screen protector is a dogged screen protector with an excellent scratch resistance, it can also be trusted in some very extreme conditions.


Experiment two: Impact force:

Brief introduction: YOSH tempered glass screen protector and screen protectors purchased from other brands are tested separately under same experimental conditions. Screen protectors are held firmly in the air and a steel ball (industrial standard weight 63g) is dropped from different heights to test the level of force the protectors can withstand.

Experiment instrument:
YOSH Tempered glass screen protector;
Screen protectors purchased from other brands;
Impact force test equipment*2.

Experiment process:
1: Set the height of both test steel ball container at 30cm, place the ball into the container.
2: Insert YOSH Tempered glass screen protector then release the ball, observe and record;
3: Insert the other screen protector under the same experimental condition then release the ball, observe and record.
4: Set the height of both test steel ball container at 65cm, place the ball into the container, perform the experiment again.

Experiment results:
The ball released at 30cm level went through and shattered the ordinary screen protector, but when it landed on YOSH screen protector it didn’t cause any damage to the protector. In fact the YOSH tempered glass screen protector was able to withstand impact force released from 65.5cm. Needless to say, this shows that the YOSH tempered glass screen protector is durable and can protect your phone from damages when it falls or slips from you.


Experiment 3: Anti Fingerprint

Brief introduction: Even if you are very careful with the way you use your phone, you might be unable to do that without leaving fingerprints/marks on the screen during your everyday uses. But the YOSH Tempered glass protector is coated with an oleophobic layer that will help you prevent fingerprints and marks from marring the screen of your phone. The YOSH Tempered glass protector from other brands to test its resistance to fingerprints.

Experiment instrument:
YOSH Tempered glass screen protector;
Screen protectors purchased from other brands.

Experiment process:
1. Place both screen protectors on a table.
2. Touch both screen protectors several times simulating everyday use.
3. Observe and record.

Experiment results:

From the results gotten from the experiment, fingerprints can be seen clearly on the ordinary protectors but on YOSH Tempered glass protector you can barely see a mark on it because the surface is coated with oleophobic layer to provide a smooth surface and prevent fingerprints from deforming the screen of your phone.
