I appreciate you conducting the tests, Tom . However, let’s clarify the actual user experience:
1. The pre-applied film was removed to examine the screen ripples.
2. The top surface of the phone’s display has been thoroughly cleaned, ensuring no oil or glue residue from the removed film protector.
3. When exposed to light, the reflection on the phone’s surface appears normal, akin to any other “FLAT” glass surface. However, upon examining the corners, specific ripples consistently appear, similar to the issues reported by other users. This issue was compared across various “FLAT” display phones like the Samsung S20 FE 5G, Galaxy M21 2021 Edition, and Realme Narzo 60X 5G, where no such “ripple” effect was observed.
4. Regarding the theory of different layers of the screen causing light refraction/reflection under the tempered glass, let’s hypothetically agree to that notion. Even so, why is there air leakage between the display surface and the tempered glass when a new piece (be it a 3rd party or official Nothing tempered glass) is applied?
5. One might argue that it’s a problem with the glue quality. However, it’s perplexing that every unit of tempered glass, irrespective of the brand (including Nothing), exhibits similar glue issues in the exact areas where the light reflection illusion is noticed.
Therefore, I urge your test team to collect handsets from affected users and conduct controlled lab tests to analyze and explain the findings definitively.
I hope this clarifies the situation and helps your team identify the root cause of the display ripple issue. 🙃
