The eBay discription states 1080p so that would be grounds for return if it isn't.
I don't find that, the wrist back and strap on a camcorder makes it easier to form tripod position rather than trying to grip a phone, maybe certain phones are easier than others, but glass backed can get slippery and also physical buttons Trump trying to poke a touch screen. I just find camcorders much more fit for purpose than phones, but at the end of the day whatever works for you.
Its still a lot easier and less effort than holding a camcorder for an hour though isn't it.
Try recording for more than a few minutes on your phone and see how shaky your hands are add a bigger sensor, much better microphone, lens, low light, fast motion etc Smartphones have their place for convenience, but a proper camcorder will win out for events, hence why movies and tv programs are not filmed on smartphones ;)
