First of all I must inform that not all information was officially confirmed (SoC can be SD430 or 435).
As I mentioned in earlier post IFA not always gives answers and not all answers given are good. Here we have partial answer – rest was filled by jurnalists who write about smartphones for some time now.
But we see one good trend within middle segment – more and more models with full metal body. It’s good because metal looks better and is more durable.
About models I can say only that they’re typical middle segment phones: nothing special but good enough to more advanced tasks. With reasonable price it will be interesting.
