The HTC One M9 boasts a much better camera than its predecessor.
Its 20-megapixel sensor captures bags more detail than the 4-megapixel ‘UltraPixel’ shooter on the One (M8).

HTC hasn’t shunned the UltraPixel tech completely though.
Rather, it has incorporated it in the front-facer, which makes much more sense, as it’s better suited to dimly-lit conditions, such as bars, where you’re more likely to take selfies.
Both handsets run Android 5.0 Lollipop out of the box, so it comes down to their skins.
Samsung’s TouchWiz is a lot less intrusive than previous incarnations, and for the first time you can delete some of the pre-loaded apps.
Not going to use Microsoft OneDrive? Uninstall it and free up some space.
It still looks a bit cheap and inconsistent though. It’s badly in need of a refresh.
