Another common problem is the moire effect, which occurs when the new screen is skewed or when the matrix is poor, to avoid this:

1. Before the final gluing, turn on your smartphone and check the uniformity of the backlight (for example, on a white background).
2. If you notice waves, carefully reinstall the screen, aligning it in the frame.

If the sensor is working after the replacement "-through one" (reacts to every second touch), the cause may be in:

• Bad touch-sensing plume contact.
• Incompatibility of the matrix with the version MIUI (It is decided by firmware or rollback to the old version).
• Mechanical damage to the touch layer (if the screen fell after replacement).
