We may have just peeled the cellophane off HTC's One M9 flagship, but there's still life left in its predecessor. Today, we (well, those in Europe) get to meet the HTC One M8s -- a revised version of last year's top billing handset. What does a lower case "s" (and about £379) get you? Mostly a camera refresh -- the M8's (note the apostrophe) 4-megapixel UltraPixel camera has been updated a conventional 13-megapixel, f/2.0 Duo-affair (the front-facer is the same 5-megapixels as before). There's been a swap-out of processors, too. The original's 2.3 GHz Snapdragon 801 quad-core is now a 1.7GHz 615 octa-core (don't let the number of cores fool you). If you were wondering if this is just another way of branding a "mini" phone. It's not. At least on a technicality -- the HTC One M8s has the same 5-inch 1080p display as the phone it shares a design with.
