So here's the thing. I'm due for an upgrade on the 1st October, and I want to make sure that whatever phone I get is the best possible phone that I can get. Now I know, it's subjective, there's no phone that suits everybody, but I'll try to explain what exactly I want. At the moment I have a BlackBerry Z10, and in my opinion, basically every phone is an upgrade from that, and I'm also in possession of an iPad Air 2 and an iPod Touch 5th generation. Now, I think we can agree that phone quality is not measured by what it has, but rather what it lacks. Now by that, I'm talking about user experience, things like fingerprint scanner, best in class display, fast wifi, I'm not talking about things like 3GB RAM, 1440p screen, 2GHz processor. Now I'm going to try to list all the variables in order of how much I care about it, starting with what I care about the most at the top, then what I care about less going down. Bear in mind that this is just my opinion. Display technology: I'm a display fanatic. Nothing beats a great screen, and I think that the best screens that I've seen so far are the ones from Samsung. Vibrant colours, looks like it's painted on, immersive, and feels like I'm touching the content. I'm not sure if I could ask for better. But that's not to say that LCDs are bad. Sure, some are, for instance I'm not a fan of the OnePlus One display, but I would be happy with a good LCD display over an AMOLED. Fingerprint scanner: I find it very useful to be able to unlock a phone using a finger. It's quick, and nobody can see your password. I don't really know what the safest and easiest alternative is, but I just know that it would be good to have it. Screen size: I like big phones. I don't have much experience with them, but ones I've tried in stores seem great. I would say that my perfect size is 5.7 inches plus or minus about 0.7 inches for a phone that I can use as a daily driver, but the closer to that sweet spot the better. Build: I'm not generally nitpicky about phone build, but I like a well built phone. That said though, I'm a small bit choosy on what well built actually means. For example, I would prefer a glass back to a metal one, so I would say that phones like the Z5 premium, and the new Samsung phones are the best built. And I actually really like what Motorola are doing with their Moto X (Style and Play) with the metal frame and silicone back. Software support: Now it's a known fact that a lot of Android phones take months to get the latest updates. I can't really speak for the future, as I don't know what's in store for later updates, but I find it quite important. Software: I'm specifically talking about Android phones here. I'm not really an expert on the different versions of Android, but I'm for the extra features that other OEMs put. But there's some sort of obsession with stock Android. I'm not doubting that it's good, but if somebody can tell me what's so good about it, that'll be great. Battery life and charging: Not really a concern to me if I have fast/turbo charging, or if it can get me through a day. Fast charging is pretty much a standard now, and Motorola's claim of 10 hours out of 15 minutes charge sounds really neat. I'm putting these two in the same section because they are co-dependant. Camera features: I like to have things that you can do with the camera, things like slow motion and manual controls. Something that basically every phone lacks is 240fps slow motion though. I think that's one area where the iPhone shines. Camera quality: Go on about megapixels, apertures and shutter speeds as much as you like, but my bottom line is this. I just want good photos. This isn't that important to me, there are things I care about more (namely everything above this) but that's just how I measure camera quality. General smoothness: I can bear a bit of lag. I'm currently running the public beta program on iOS, and obviously performance isn't as good as it could be, but I don't mind. What I don't like is constant crashing. App/webpage refreshing is a minor problem to me. Waterproofing: It's not a standard feature, but I find it pretty neat how I can have a phone that survives the toilet or one that I can take to the pool. Display resolution: This is the one thing about the display that I don't really care about. Anything higher than 1080p, which every flagship phone over 5 inches has, doesn't really concern me, it just doesn't make any difference to the user experience to me. I would only use 1440p as a deciding factor if I was completely torn. And of course we shouldn't ignore price. I don't yet know how much I'll have to pay for each of the phones, as the upgrade prices only come up when I'm eligible. I don't really have a budget, I'm just deciding based on value for the money. If people can recommended phones based on my needs that would be excellent, but what I really want to know is experience. So can you just post what phone you have, and say what I might or might not like about that particular phone. Thanks.
