Here are a few tips for taking care of cell phones, game systems, and other handheld devices.
Always keep the dust covers closed. Most handheld devices have an IP rating, which indicates dust & waterproof status. The higher the number the higher the protection against dust and water getting in. Some have a separate dust cover/protective case. That rating doesn’t matter if the cover is not used. This can void the warranty. Use a case. It may not offer 100% protection, but some protection is better than none.

Do not abuse the device. Some devices cost over $1000 dollars even though they may not look like it. While these are portable devices, that doesn’t mean they can withstand being dropped onto a hard surface, or tossed around. The better you treat the device, the longer it will last without needing service.
Keep the devices clean. Even though the device may be in a case, if there is something on the screen, it can cause the device to misregister a touch, which can cause problems. Remember to apply cleaning solution to the cloth or paper towel, and never directly to the screen.
