Why does a phone case get discoloured?
You can often find a yellow shade that starts appearing on the plastic, clear phone. Although this in no way causes any harm to the mobile or the cover and does not deteriorate its quality either, it doesn’t look very pleasing. One of the leading causes of this is overheating of the phone. You can remove the cover when the phone is at a low battery range or while charging to avoid this issue. However, there is little that you can do after the case gets discoloured.
