I have used htc desire 820s for like 2 years.specs were great 5.5 inch screen with high resolution.the look was stunning and also light weight. colour combination are also great.i would recommend grey+blue model.high end games run smoothly.but the only problem is its still runs on kitkat 4.4 version.htc may not be the best smartphone in this price bracket, but its still an impressive device that looks good.
