These are several tips you can follow to improve the life span and functioning of your electronics:
Smartphones and tablets can carry more bacteria and germs than found on a toilet seat! It is therefore important that you clean your electronic often as well as its case. This will ensure that the bacteria and germs are removed. Use a microfiber cloth to clean your electronic on a regular basis.
It is best to get into the habit of not using your phone while you eat, instead reach for your electronic after you have washed your hands.
