And here are the main reasons why. Customization: I miss it more than I thought, though not a deal breaker. White: Every damn thing is white, I hate it. Signal: Shockingly bad. This is THE reason for switching back. I borrowed an S4 for a couple days and never lost a call or failed to send a text once. On my iPhone I genuinely struggle to even get a signal at home. If I lay it on my mac it's an instant 'no service'. The S4 cares not what I choose to dump it on. I may keep my iPhone for the sake of syncing my calendars and all that with my mac, but it's days of being my main phone are over. A great shame, as overall it's a great little device. TL;DR: I love my iPhone but as a phone it is literally the worst I have owned in over 10 years' worth of devices.
