The first smartphone from Samsung with metal housing have problems with signal reception
This year Samsung has listened to customer requests and released a line of smartphones with all-metal housing . And there has not been without surprises. As shown by the first tests, model Galaxy A3 and A5 have problems with signal reception. This is a fee for the metal shell and the result of lack of experience in the creation of all-metal Samsung smartphones.
During testing, Hi-Tech.Mail revealed that the new Samsung smartphones metal reception significantly worse than in the plastic devices from the same manufacturer.

Plastic, for example, no screens, and in the case of a metal phone need external antenna to conclusions, because if they are entirely closed metal, the network Wi-Fi, of course, there will be problems. All manufacturers solve this problem in different ways, have someone get better, someone – is worse, “- quoted as Associate Professor of General Physics and Wave Processes Faculty of Physics Nicholas Brandt.
With Wi-Fi there is a similar situation, but the problem may not cause severe discomfort, at least at home, if it comes to a small apartment with a powerful router.
