      More detailed

      Measurements of LG G7 Default were carried out by Roman Kuznetsov on the hardware-software complex RAA.

      The LG G7 Default test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.
