Precautions before installation1. Tip 1: Before InstallationTesting Do not remove any protective film or labels during testing. Please be aware of static electricity problems.Always ground yourself using an ESD (Electrostatic Discharge) strip before attempting any repairs. This will prevent static electricity from damaging the electronic components inside the phone.Make sure to wear goggles and be careful not to cut your fingers on glass shards.2. Tip 2: Simulated TestingScreen replacements are very fragile products. We strongly recommend testing before installation. Please simulate the test, that is, the phone is disassembled, (motherboard + LCD or screen) connect the audio cable and replace the new one, turn on the phone, and the test is completed. If the test is normal, please install. If it can not be displayed, please contact us at the first time. Please do not force it to install in your phone. Once the screen is installed, we will not take any responsibility.3. Tip 3: Do not overbend the cableMake sure that the LCD cable is not bent excessively. Bending more than 90 degrees will result in a black screen.About the product1. Replacement LCD display + touchscreen digitizer kit for Asus Zenfone Max Pro (M2) ZB631KL. 2.2.
