Having a smartphone should always be careful not to be easily broken. Of some of the events that I often find, the average smartphone damaged usually on the screen and also the battery. But it is possible, some other part of the smartphone can also experience serious damage.
To avoid this, it is necessary to some precautions, especially for perishable parts earlier. If the smartphone screen is the most crucial to performance is maintained, then you can install the screen protector is made from the material of choice and quality of course. The use of a screen protector is already a common thing to do, which is often a smartphone screen scratches are often exposed to sharp objects.
As for the other part is the battery condition should also receive attention. Damage often occurs on a smartphone battery usually due to the condition of the battery and not fake quality. You must check the quality of the battery at the time of buying a smartphone, whether the battery is genuine or fake. It would be better if you ask for warranty on all hardware and software on the smartphone.
