Privacy Tempered: In today's digital age, mobile phones have become an integral part of our personal lives. This is why many people install privacy tempered glass on their screens to prevent people sitting nearby from peeking into their phones. While this seems like a safe and smart option, it also has some disadvantages that most users are unaware of.
Screen brightness and clarity decrease
The biggest drawback of privacy tempered glass is that it significantly degrades the original screen quality. Its special filter layer darkens the screen when viewed from a side angle, but also reduces brightness when viewed from the front. As a result, using the phone in sunlight or bright light becomes difficult and puts more strain on the eyes.
Reasons for high battery consumption
Many users don't realize that after installing privacy glass, they need to increase the phone's brightness. Repeatedly setting the brightness to full to see the screen clearly drains the battery faster. This habit can also affect your phone's battery life in the long run.
Affects touch response
Some cheap or locally produced tempered glass products can reduce the phone's touch sensitivity. Sometimes, you'll miss characters while typing, or the screen won't respond properly. This problem is especially noticeable when gaming or scrolling quickly.
Increased pressure on the eyes
The screen already appears dark, and the brightness needs to be increased. This puts additional strain on the eyes. Staring at the phone for long periods of time can lead to headaches, eye irritation, and fatigue, especially for those who use their mobile phones excessively.
Privacy glass is not necessary for everyone.
If you use your phone mostly in a secure environment like home or office, privacy tempered glass is rarely necessary. Regular tempered glass is sufficient to protect the screen from drops and scratches. Additionally, app locks and privacy features in your phone's settings can also help keep your information secure.
Should you delete it?
If you want better display quality, longer battery life, and a more comfortable user experience, consider removing the privacy tempered glass. Choosing the right accessory for your needs and usage is the wisest decision.
