The protective glass gives the screen extra strength and durability. At the same time, due to mistakes made during the installation of the glass, intensive operation and/or lack of care, the protective coating peels off and becomes unusable. The article contains the main reasons why the protective glass on the iPhone comes off, as well as ways to solve the problem.
Insufficient screen treatment before glass installation
It is important to thoroughly clean the screen before applying the protective coating. Greasy spots, stuck dirt, dust or small debris prevent the glass from snugly fitting to the screen. Bubbles and/or air layers form, which impair the display of information. If the air voids are located on the edge of the glass, such places will quickly collect various debris and spoil the adhesive coating. As a result, the connection to the screen will be broken, and the glass will gradually peel off until it breaks or comes off completely.
Solution: clean the glass and restore the adhesive coating
Remove air bubbles by following the instructions in the article on how to remove bubbles from the protective glass of the phone. Wipe the screen thoroughly with an alcohol wipe to remove debris and accumulated dirt around the edges of the screen before re-installing the protective coating. Use Guide Sticker or office tape to collect the debris from the back of the protective cover.
If air layers form at the edges after reinstalling the glass, restore the adhesive ability of the glass with glycerine or an appropriate reducing liquid. Apply a few drops of liquid at the place where the glass is detached. After a while, the tool will fill the void under the glass and provide the necessary connection to the screen.
In some cases, UV gel may be needed to firmly connect the glass to the screen. The method of applying the product is similar to a conventional liquid, while the UV gel must be dried using an ultraviolet lamp or under the sun. The frozen gel firmly holds the glass, eliminating peeling in places with a broken or missing adhesive coating.
Debris on the edges of the glass
Most safety glasses do not cover 100% of the screen area. On each side, there is 1-2 mm of space where dust and other debris accumulates. After some time, the adhesive base at the edges of the glass weakens and leads to peeling of the glass.
Solution: cleaning the glass
Periodically clean the surface of the glass and in places where debris accumulates. To do this, use cleaning kits that include liquid and soft rags. Some kits also include a brush to remove debris in hard-to-reach areas.
Unevenness and/or chipped glass
Some safety glasses initially contain defects in the form of irregularities, flimsy or damaged adhesive base. Problems are usually found with cheap and/or fake glasses. Also, the glass is often peeled off in damaged areas where there are chips or cracks.
Solution: exchange the glass or eliminate the identified defects
Before buying protective and other accessories, always ask about the availability of a warranty and the possibility of exchange or return, in case of defects. And if you find any visible defects in the glass, agree with the seller to exchange or return the glass.
If the return and exchange is not possible or the manufacturing defect was discovered after a while – fix the defects or install a new glass. The most common problem with defective glass is unevenness or an adhesive base that has dried at the edges of the glass. In most cases, treatment with glycerin or UV gel helps in places where the glass does not fit properly to the screen.
Damage to the adhesive base of the glass
The adhesive base of the glass at the edges is easily damaged by the use of aggressive cleaning agents: isopropyl alcohol, alcohol-containing makeup remover, etc. As a result, voids are formed at the edges, which are clogged with garbage and accelerate the peeling of the glass.
Solution: Use only suitable cleaning agents
Recommended cleaning products do not contain alcohol or the alcohol concentration is so low that it does not harm the adhesive base.
In places where the adhesive base is damaged, you will need to restore the sticky layer with glycerin or UV gel. If such places are clogged with garbage, you will need to remove the glass, clean the contaminated areas, and then install the glass back.
Chips and cracks on the screen
Some users install protective glass on the broken screen to fix the damaged areas. At the same time, in places of chips or cracks, the adhesive coating is not enough to fill the voids formed as a result of damage to the glass. Therefore, in such areas, the joint strength is low, which often leads to peeling of the glass.
Solution: fill the voids with sticky liquid
In most cases, the application of glycerin or liquid adhesive in the places of chips or cracks will help. The tool will fill the voids and ensure a tight fit of the glass to the screen. To fill the voids in the places of large chips, it is better to use UV gel, which will provide the best fixation in the places of the damaged screen.
