Xiaomi Redmi Note screen 8T Has the problem suddenly stopped responding to touch? This problem can occur due to software failures as well as physical damage. Unlike a full-on bricking device, when the phone is not turning on at all, a broken touchscreen can often be repaired without visiting a service center, but it is important to correctly diagnose the source of the malfunction, which will save time and avoid unnecessary waste.
In this article, we will examine all possible causes, from the banal system freeze to the failure of the display plume, you will learn how to distinguish hardware from software failure, which manipulations can be performed independently, and in which cases it is worth contacting specialists.

- π The phone performs actions (opens apps, scrolls menus) without your involvement ("ghost touchesΒ»).
- π³ Responds only to certain areas of the screen (for example, the upper half works, the lower half does not).
- π After connecting to a charge or reboot, the touchscreen briefly comes to life, but again fails.

β οΈ Attention: If after resetting the touchscreen worked, but after a while the problem returned - this is a sign of wear of the sensor layer or poor contact of the plume.
3. Hardware causes: when the "iron" is to blame
If the software methods didn't work, the problem is probably physical damage to the components. Let's look at the typical scenarios.
