As smartphones store vast amounts of personal data, the need for privacy screen protectors has surged. A review of the ESR privacy screen protector used on the Galaxy S25 Ultra revealed effective functionality, blocking visibility from various angles while retaining screen clarity from the front. This enabled comfortable private use in public settings, like subway commuting. However, a potential issue was noted when the phone's display abruptly dimmed, raising concerns about how the screen protector could be impacting display performance under certain lighting conditions.
Considering how much personal information we store on our smartphones, the demand for privacy screen protectors is at an all-time high.
The ESR screen protector worked exactly as intended; when staring at the S25 Ultra from the center, the display still looked bright, sharp, and vibrant.
For the first time in a long time, I felt comfortable answering work emails and exchanging personal messages while on the New York City subway.
The display suddenly dimmed itself... the shift in brightness shouldn't be as dramatic unless I'm moving between two drastically different lighting environments.
