Note: Do not use any UV based glue on realme 11 Pro 5G Series leather back cover variants, as doing so could damage the device and void the warranty.
To protect our phones, people often apply tempered glass screen protectors. However, if the screen protector installation is not done professionally, it could compromise the integrity of the smartphone.
Issues with using a UV Glue Tempered Film
UV glue tempered film is one type of screen protector that utilizes a drop of UV glue on the smartphone's screen before curing the glue using ultraviolet light. This installation method provides better adhesion than conventional solid glue tempered films, resulting in a more secure fit that is less likely to detach during regular usage.
However, using a UV glue tempered film on mobile phones is risky. Some risks it poses are the following:
1. Formation of bubbles on the screen: Before installing a UV glue tempered film, the UV glue must be evenly applied onto the screen's surface and subsequently covered with a tempered film. Improper execution of this method may result in uneven glue distribution and the formation of permanent bubbles on the screen's surface.
2. The buttons can malfunction: During the application process, the UV glue used in a UV glue tempered film has the potential to seep into the gaps located between the buttons of the smartphone and along the arc of the screen and middle frame. If not detected and addressed before curing the glue, this can cause the buttons to adhere to the shell of the phone, leading to their functional impairment.
3. The earpiece speaker might produce a muffled sound: UV glue can also easily infiltrate the earpiece speaker's small perforations. Upon the glue's curing, the speaker holes can become obstructed, causing a muffled or complete lack of sound output.
4. Touch screen and fingerprint failure: The thickness of the tempered film can exceed that of the device's built-in protective film by two-fold or more. This thickness disparity can cause deviations in capacitance sensing upon touch input, ultimately impairing touch screen responsiveness. Additionally, under-screen fingerprint recognition may be compromised due to the tempered film's effect on light transmission, leading to less sensitive recognition of fingerprints.

Risk Warning
The warranty does not cover the phone failure caused by improper UV adhesive tempering film use.
1. To prevent the UV glue from spilling into the holes and affecting the use, it is recommended to use the supplied side hole sealing film to seal and protect the body holes before applying the film and remove it after the film is completed.
2. The body holes include: the receiver, power button, volume keys, speaker hole, SIM card tray, primary MIC hole, and secondary MIC hole; the specific location can be seen in the lamination position schematic below.
3. UV glue is corrosive to leather; if the phone battery cover is made of leather, please do not let UV glue directly touch the surface of the leather battery cover.
User guidance
1. Uncover from the gray area ①.
2. Point the arrow ② to the screen.
3. Use graphics ③ and ④ to position and stick to the corresponding hole of the phone.
4. Stick the seal tightly around the open hole.
Note: When laminating, please pay attention to the side of the screen that needs to be completely laminated. It can not be wrinkled or leave a gap to prevent UV adhesive from the gap into the hole to damage the phone.

After the film is pasted and the UV glue is completely cured, remove the sealing film and clean the remaining glue around it.
