Usually our phone cases are tested for yellowing and are still clear and transparent for at least six months.
But for yellowing, we have come to the conclusion after testing.

This happens due to material degradation, which can be caused by all sorts of environmental factors, including:

Ultraviolet light from the sun degrades the chemical bonds between molecular chains that build the case. As these bonds break, the natural yellow color of the material becomes more apparent.
Heat also degrades chemical bonds. The sun or even your hands can heat your phone and, therefore, your case.
The natural oils on your skin build up on your case over time, and as it does, the case may appear more yellow.
With a bit of forethought and maintenance, you can keep your case clear for longer. A regular cleaning routine helps prevent the buildup of oils so the colors of your phone shine through.

UEENCE's products are made to order and hand-inspected from corner-to-corner to ensure high-quality products that you can count on. Phone cases made of shock-proof or drop-proof materials are usually test-certified for specific purposes. It depends on the individual's needs when choosing the best phone case for your device. Stay up to date on all UEENCE promotions to get the best deal on phone cases and tech accessories.

Phone cases do not necessarily cause overheating. There may be a trapping heat when putting on the phone case, but avoiding having too many applications opened on your device, overexposure to the sunlight and always keeping your device in a cool place can help reduce the risk of overheating.

Different cases are made of different materials, but most contain natural silicone.

The easy way to remove a phone case is to first lift one side or one corner up from the bottom of the case, then gently remove the case.
