That is exaggerating, barely, however try to be excited about sturdiness once you purchase any new cellphone. The common measure of a device’s water and mud resistance is its IP certification. So what is the best IP rating obtainable on smartphones? For that matter, which IP rankings do you have to keep away from?

Which IP rankings do you have to keep away from?
Some do not actually provide a lot safety
We would strongly counsel skipping most units under IP57 — it is really easy to seek out merchandise at or above that ranking that it often does not make sense to sacrifice safety.
