I highly doubt the One's camera is superior to the GS4. And the expandable SD card slot is a nice extra as well. People can just slide their current card into it and keep i moving
The camera on the One was hyped up before it dropped, but it's only good at taking shots in low light which is good, but the sharpness and clarity of the pictures are lacking... they dropped the ball with that. If HTC wants to get back where it was, they can't hold anything back. The only 2 phones where they didn't hold back on out of all of their lines in recent years is the OG EVO, and the EVOLTE4G.
I say that because those were fully featured devices that offered everything the tech enthusiasts ask for. Great camera, HDMI out (OG EVO), SD card, and 4G, great build quality (LTE moreso than the OG)
Another thing that Samsung has over HTC is their signal strength for LTE. My wife has a GS3 and I have the LTE and we can be in the same room, same place, same area, and her phone will be swimming in LTE while mine is looking for it. I have to put my shyt in airplane mode at times and dance with the radios just to get it to connect.
They need to stop skimping on features if they want to come at Samsung. Even though Sammy makes that plastic bullshyt as far as the quality, they pack that bytch with every feature a nerd would want...
