It happens every day, and you’ve surely experienced it as well: Your phone’s just beeped in your pocket, so you quickly and carelessly reach to pull it out.

So how does cell phone repair work? Assuming you aren’t totally clumsy, you can also repair your smartphone yourself if it’s just damaged glass you’re dealing with. This is where you’ll find instructions and the most important answers to your questions.

Why repair it yourself?

Defective smartphone display and tools

Cell phone repair kits are available online for 20 to 30 euros. They usually consist of an adhesive film and the matching replacement glass. Other accessories for this repair project are time (about one to two hours at most), adhesive tape (preferably double-sided), a blunt and a sharp knife, a small suction cup, a hairdryer, and a helping hand — after all, you can always use one.

Tutorial: Repair a cell phone and smartphone display yourself

The following tutorial provides step-by-step instructions for repairing a defective display on a cell phone:

  1. Turn off the cell phone to prevent a short circuit.
  2. Before opening the cell phone, it has to be warmed up. This is because the display is often very strongly glued to the rest of the casing — you first have to soften the glue to remove the glass. A hair dryer works best for this heating process.
  3. When the edge of the display is nicely warmed up, the suction cup can be applied and the display can be pulled up.
  4. Once a narrow gap has been created, insert a flat, sturdy tool into the gap. Slowly and carefully work your way under the glass, from the bottom up. The cell phone should remain warm during this process. A helping hand can be very useful here.
  5. Once you’ve made your way around the display, you can slowly lift up the glass using the suction cup and carefully separate it from the rest of the phone.
  6. Small scrapers should be included in the repair kit! One of them can now be used to clear the display of any residue.
  7. The touch sensors can now be covered with the double-sided adhesive tape. As additional protection for the future, it is also recommended to tape the edges again. This protects the smartphone from contaminants down the road.
  8. Now stick the adhesive film on the cell phone.
  9. Carefully peel off the protective film.
  10. Remove dust, dirt, and other contaminants from the LCD display.
  11. Carefully attach the glass and heat everything again with the hair dryer. This allows the adhesive to bond strongly.
  12. Insert the battery and turn on the cell phone — it’s ready to be used again.

What helps against cracks in the display?

Unfortunately, cell phone displays scratch easily. Even though the internet has all sorts of home remedy suggestions such as baking soda or toothpaste, you should put a few euros into polish paste and anti-scratch kits. They solely exist for this purpose.

Should I use an original or third-party part?

Spare parts for your cell phone can be expensive if you buy them from a partner that is authorized by the manufacturer. To save money, you quickly resort to third-party providers and sometimes don’t even know what you’re doing to your cell phone. Costs can be saved, but often damage occurs after the repair. Even though the low price is tempting, third-party providers should be avoided.

Where can I order spare parts for the display in a store?

When it comes to spare parts or repairs, an authorized partner is always the right way to go. They are certified by the manufacturer to perform services such as a repair. Online, you can go to the manufacturer’s site — such as Apple or Samsung — and search for authorized manufacturers from the region.
