Current & Voltage Multifunctional Tester

A COSTLY MISTAKE！

WARNING FOR NOTE 20 ULTRA MODEL

***Many users are unaware that improper screw installation can lead to severe damage to their device's screen. During the replacement process, if a long screw is mistakenly used instead of the correct short screw, it can cause irreparable harm to the delicate LCD components.Unfortunately, current technology does not support repairing this type of damage, meaning users are left with no choice but to replace the entire screen assembly, a costly and time-consuming endeavor.

***To prevent long screw damage, users must exercise caution and attention to detail during screen replacement. Always use the original short screws provided with the device and carefully inspect them for any signs of damage or irregularities before installation.
