It generally has no effect on mobile phones.
However, the following factors will have a certain impact on the three defense performance of the mobile phone:
Mobile phone shell quality is not good; Replacement technology is not mature. It will directly affect the waterproof and dustproof performance of the mobile phone. Moisture and dust easily enter the inside of the phone.
After mobile phone maintenance and disassembly, the sealing performance of the shell may be affected, it is recommended to use a fully closed mobile phone shell, preferably thicker, and a thickened mobile phone with four corners. This will effectively increase the waterproof, dustproof, and anti-drop performance of the phone.
There is no problem in changing the original factory, because many of the non-original factory are produced by small factories, the mold precision of the shell is not enough, after replacing it, there will be dust into the screen, the seam is not tight, the back cover is loose and so on, affecting the use of mobile phones, so we must carefully buy when changing the case.
It might not match the front shell. It's a shade off.
