Dropped in water
or on the ground.
Left in the heat
or even stepped on.
These are things that can happen to any given smartphone
So, how durable are our smartphones?
We'll be sharing some of the reliability tests we carry out at Samsung
to show you how tough GALAXY S4s are made to be.
First, is what we call a 'CONSECUTIVE DROP TEST'.
The product is dropped from the approximate height of a desk
over and over again.
After dropping the product hundreds of times,
we check to see if the product is alright.
This is slightly stronger.
Simulating unexpected drops,
we let the product free fall.
Products that have undergone this FREE-FALL TEST
can only pass if there is nothing wrong both externally and functionally.
TUMBLE TESTs are performed as well
to prepare the phone from drops from the top of a case of stairs.
As you can see, a variety of situational DROPPING TESTS are done,
hundreds of sets each.
The GALAXY S4 is also designed to withstand impacts strong enough to shatter walnut shells.
Especially, as for the glass covering the screen,
it can only pass the test if it does not get damaged from a metal ball dropped from a considerable height.
What happens when you accidentally drop your phone in a sink full of water?
SINK TESTs recreate these types of situations.
This process is to test for GALAXY S4's level of water resistance
But of course, you shouldn't dunk your phone in water on purpose, right?
TEMPURATURE/HUMIDITY TORTURE TESTs put products in extreme circumstances and see how they work.
Only products that pass these extremely high temperatures and humidity pass the test.
Tests to check its resistance to electrical shock and dust penetration are also caried out.
And thousands of other tests we weren't able to show you are also undergone to ensure the reliability of the product you receive.
