When screen replacement is inevitable: signs and risks
The Xiaomi Redmi Note 7 screen is one of the most vulnerable parts of the model. Even a slight drop from a height of 50-70 cm can lead to cracks, a "web" or complete sensor failure. But how do you know that the display really requires replacement, not temporary repair? First bells: flickering screen when turned on, broken areas of the sensor (for example, the top does not respond), or colorful stripes that appear when the device is heated.
Many users mistakenly believe that small cracks are just an aesthetic defect. In fact, even micro-damage can lead to moisture penetration under the glass and corrosion of the plumes, which in the long run will turn into expensive repairs to the motherboard. Another common scenario is that after a fall, the screen works, but after 2-3 weeks it begins to "glut" - spontaneously press icons or turn off. This is a sign of damage to the digitizer (touch layer), which only gets worse over time.
It's important to distinguish software failures from physical damage. If the Redmi Note 7 screen doesn't respond to touch, but the image is clearly displayed, the problem may be in the firmware or drivers, in which case a factory reset (Settings β About Phone β Settings Reset) will help. If the display shows black spots, stains or it is completely gone, this is a 100% hardware malfunction that requires the intervention of the wizard.
