Foolproof: choose a secure phone

Защита от дурака: выбираем защищенный телефон

A couple of years ago we did an interesting selection of rugged mobile phones and smartphones. Their range, as the demand is much lower than the “normal” models and every few months update the article makes no sense, but every couple of years — completely. To repeat the text of the first article makes no sense, everything can be read in the original article, but to guide the choice we will be approximately the same core criteria and classes of devices, and at the bottom of the article is the same “cheat sheet” with a breakdown of protection classes for the convenience of readers. Specialised range of protected vehicles in its number of available models remained the same: the model is new, but their number is approximately. At the same time, over the last couple of years manufacturers of “conventional” smartphone, A-brands in the first place, decided that their flagship smartphone should be protected from dust and water. This applies to Samsung, Apple, LG, Sony (first to start this tradition), and even began to catch up with the Chinese, Xiaomi in particular. It can not but rejoice: more choice is always good.

Many of the manufacturers that spetsializiruyutsya on secure models, naturally increasing capacity and resolution of the screens of their smartphones (which is good, of course), but for some reason rarely do design with physical protection of the screen (all sorts of plastic and rubber bumpers above the screen reduce the chance of it to break the fall). Otherwise, everything is unchanged and we tried to fit a variety of models from different price range and with different features (push-button phones, smartphones, models with a Walkie-Talkie and so on). Studying the question and the range I began to be dazzled because of the abundance of various Chinese “nouneym”-models, including a very epic under the brands of cars and the same model under different brands (OEM production). Please share your impressions in the comments if there is a personal positive or negative experience with any similar devices. I’m sure it will be useful for those who just choose something similar.

Of course, the smartphone is very thick, aggressive rubberized plastic casing on the ends of the metal insert, and weigh more than 300 g Smartphone is interesting because it features almost to the max, if judged from the point of view of such devices: in addition to the armored hull it boasts a dustproof, waterproof according to the IP68 standard, all the connectors are closed with plugs, there is a separate transmitter with a range from 400 to 480 MHz and connect an antenna (not Zello), accelerometer, compass, temperature sensor, pedometer, support for GLONASS, GPS, aGPS, Beidou, module NFC, infrared port to control electronics and battery 6,000 mAh.

If this issue really care about, you should pay attention to Sigma-mobile, whose chief office and official service in Kiev, plus representatives of the company actively respond to user comments in the reviews on the websites of the shops and from time to time issued software updates for smartphones. Of course, it’s — branded smartphones (phones and tablets) one of the Chinese OEMs, but nothing wrong with that, that’s a huge number of brands. At the moment the most relevant and “top” model Sigma mobile X — treme PQ35. This is a less hardcore model, which is closer to the usual smartphones.

This is one of numerous Chinese C (or D) of the brands that recently we have quite an actively began to sell online shopping. Apparently, the demand really is due to the low price tags. About the quality and defect rate won’t write anything, I think that in the comments owners write about your experience. This is the most expensive protected model: Blackview is still BV7000 Pro. It’s more powerful, thinner and equipped with a thumbprint scanner, but all this is not unequivocal advantages in the case of a protected smartphone: fingerprint scanners (most of them) do not work well with wet fingers, and thickness reduction resulted in a decrease in battery: 3,500 mAh, which is somehow not enough by the standards of its class of devices. In BV6000s protected by standard IP68, the frame is made from metal, the outside is rubberized plastic and metal inserts at the sides with large metal buttons.

Now most A-brands have released flagship with dust and moisture protection, and if you don’t need the “armored” option, then there are plenty to choose, everything depends on personal preferences and wallet. There’s a safe line of Samsung Galaxy A 2017 Sony Xperia XZ, LG G6 c additional certification MIL-STD-810G (though the glass front and back panel to break is not difficult), Samsung Galaxy S8 and S8+ and an iPhone 7 and 7 Plus.

Standard IP (Ingress Protection Rating) — enclosure protection of electrical equipment against penetration by solid objects and liquids. First digit — protection level against ingress of solid objects, the second fluid:

Protection against the ingress of foreign objects
IndexProtection against objects of diameter, mm
without any protection case
1protection against large foreign bodies > 50 mm
2protection against foreign objects of medium size, more than 12 mm
3protection against foreign bodies of small size, more than 2.5 mm
4protection of granulometric foreign bodies over 1 mm
5protection from settling dust (protection against internal damage due to dust)
6protection against dust (totally exclude the ingress of dust)

The degree of protection against liquid ingress:

Protection against liquid ingress
IndexProtection from liquid
The lack of protection from moisture
1protection against vertical water drops
2protection against drops falling at any angle up to 15°
3protection against drops falling at an angle up to 60°
4protection from pouring from all directions water
5protection from flowing under pressure from all directions water jets
6protection against short-term flooding (storm protection)
7protection against condensation protection for partial or short-term immersion in up to 1m
8Protection against water under pressure (a long dive to a depth of 1m)

Military standard MIL-STD-810: resilience to shocks, drops, gravitational overloads, low and high temperature, noise, vibration, exposure to liquids, mildew, solar radiation and so on, more details you can read in Wikipedia.

This all is to understand all these degrees of protection and certificates do not guarantee that your mobile phone or smartphone that can withstand any tests or going to work forever. You should not have any illusions, there is nothing eternal and unbreakable.
