Do Samsung Galaxy M40 Comes With Waterproof Body?

Since most Samsung Galaxy smartphones come with IP67 or IP68 waterproof rating, so it’s likely to assume that the new Samsung Galaxy M40 might be waterproof. A waterproof smartphone can offer much more features and durability over a regular smartphone. For instance, you can take underwater selfies, talk with your loved ones in rain and much more.


An IP rating is an international standard which is used to define levels of sealing effectiveness of modern smartphones. These IP ratings are presented in the form of IP followed by two numbers.

IP68 rating is the best that a smartphone can hold. However, it is important to note that this IP testing is done against fresh water. So you might end with slightly different results against salt water or other liquids such as soft drinks.

You will be slightly disappointed since there is no official IP rating for this device. However, we will confirm that in our Samsung Galaxy M40 waterproof test.
