- Touch failure: Although the image is visible, the screen does not respond correctly to touch or there are dead zones.
- Damage to the LCD or AMOLED panel: If spots, strange colors appear, or the screen goes black, the entire system will need to be replaced.
- Total breakage (glass + LCD): The repair always consists of replacing the entire module.

Differences between changing only the glass, the LCD, or both
Many users hesitate between replacing just the glass, the LCD (or AMOLED) panel, or both. Currently, most manufacturers sell the complete assembly (touchscreen attached to the display). However, on some models, only the damaged part can be replaced:
- If only the glass is broken and the image looks perfect, you could replace just the glass, but it requires very advanced tools and knowledge and can leave smudges, dust, or poor adhesion.
- If only the LCD fails but the glass is not broken, some repair shops may replace just the display, although this is not always possible.
- The safest and most common option is to replace the entire unit (glass + touch screen + LCD/AMOLED), as this ensures optimal performance and durability.
Official technical services always recommend changing both parts at the same time., to avoid future failures and preserve the warranty.
