The mobile phone screen is the most used and essential component in any smartphone., since we use it to interact with the device and access all its functions. Its importance is indisputable: without the screen, there is no way to control the operating system or installed applications. This element relies on an advanced network of sensors, allowing each touch to open an application, navigate menus, or execute commands.
Today's panels are designed to withstand intensive use, but a fall or impact can compromise their integrity.Even though some models feature protections like Gorilla Glass or Dragontrail, no glass is completely unbreakable. Therefore, using silicone cases, reinforced cases, or screen protectors is a fundamental ally to prolong the device's lifespan. These protections absorb some of the impacts, although they usually increase the thickness of the phone.

- Complete loss of visibility or blacked-out areas: The damage is serious and requires comprehensive repair.
Homemade and temporary solutions for broken screens
There are several temporary and homemade alternatives to deal with a broken or visibly cracked screen. Warning: These methods usually work only as a temporary solution until the permanent repair is made.
- Using transparent adhesive tapePlace the tape over the damaged area to prevent glass fragments from breaking loose and protect your fingers from cuts. First, clean the surface thoroughly with a dry cloth.
- Tempered glass or gel screen protectorInstalling a guard over the break helps keep the fragments in place and prevent further damage from further falls. If the damage is minor, it can improve appearance and safety.
- Specific adhesives for mobile phones: Don't use superglue or household adhesives (like Loctite), as they can damage the panel. Technicians use adhesives like E8000, which is clear, flexible, and safe for electronic components. If you decide to use it, apply only a tiny amount to the crack, without overdoing it, to prevent leaks into the interior of the phone.

What to do if the screen is faulty but not broken?
Not all screen problems are due to physical breakage. You may experience failures due to software, calibration errors, or sensor wear.Learn to identify the source of the problem to apply the corresponding solution:
- The screen does not respond to touch: This may be due to a temporary software glitch. Try restarting your phone, or if the error persists, perform a hard reset (make a backup of your data first). For similar cases, you can also consult How to fix common Android problems.
- Stains of different colorsWhite, green, or purple spots can be caused by pressure, impact, or improper adjustment of the display software. If you see green spots after an update, check the software and avoid exposing your phone to sunlight or extreme temperatures.
