I would lose the home button and replace it with duel front facing speakers move the fingerprint scanner to the back or maybe the right side aka Sony. I would partner up with say V-Moda to bring a premium sound to the the device. I go back to the flat design but keep the edge features replace the cheap earbuds with something more premium and have them match the color of the phone. I would upgrade to 6gb ram and offer 128 and 256 storage options while keeping the sd card add adopted storage. I'd go with one SOC Samsung latest also partner up with a top camera manufacture to bring the best camera ever and make the device ip68 latest Gorilla Glass and upgrade to 4K display with a minimum 4000mha battery. Tell me what u like or hate.
