DOOGEE S55 waterproof and shockproof smartphone: the most efficient one

Enlarge the image

DOOGEE S55 smartphone résistant étanche et antichoc - 1Truly invincible (this shock-resistant smartphone survived all our crash tests without a scratch), tireless with its battery providing exceptional standby time, and just as impressive for several days in a row in constant use, equipped with state-of-the-art components to boost a performance often judged mediocre on this type of device designed for outdoor professionals, the S55 from DOOGEE (under Android) effortlessly positions itself on the first step of our podium. The truth is that it offers unbeatable value for money in today’s market.

The only downside is that this rather bulky, unbreakable smartphone can be very inconvenient in some situations, difficult to store or handle.

Samsung G390 Galaxy XCover 4: the most ergonomic

Samsung G390 Galaxy XCover 4 - 2Small, light, ultra-easy and pleasant to hold, this waterproof smartphone visually resembles a Samsung all the more classic: at first glance, it does not seem to have received a steroid cure unlike its competitors. That’s where its advantage lies: its small size and all-purpose mat is very practical to store it anywhere, in the most extreme conditions, but make no mistake: it’s very resistant. In addition, it has a grip surface on the back for a secure grip. Our testers validated the little extra that our testers found: the side button with customizable shortcuts to quickly activate a commonly used feature without having to unlock the phone to look for it afterwards, super convenient and safer! To sum up, the ergonomics of this small, solid smartphone have been very well thought out for the most uncomfortable and risky situations: suspended use for example. While the overall performance is far from making it a war machine, it is still more than sufficient for normal use.
