 It seems like everybody out there is trying all sorts of weird tricks to make the screen on your phone as big as possible. Now you've obviously seen all kinds of different notch designs on everything from the iPhone 10 to the OnePlus 6T to the Pixel 3 XL. And soon you'll see phones with hole punches in them too, like the Honor View 20 and probably the Samsung Galaxy S10. We're even seeing companies use folding designs to cram a bigger screen into a smaller size. But the way you get the most screen on your phone is to not cut it out at all. But where do you put the selfie camera then? Well, how about here in a slider behind the screen? Question is, is this really what we want? What does the sliding mechanism even do to a phone? This particular phone is the Xiaomi Mi Mix 3 and it's one of the first models available with this manual sliding design. Now we're probably going to see this from a few different manufacturers this year. Rumors are already saying that the OnePlus 7 will have a similar sounding sliding design and I really would not be surprised if we see other phones from Oppo, Vivo, Honor, Huawei and more coming out with this style of phone. Now don't consider this a full review, but if you're curious about the Mi Mix 3 specifically, it has most of the standard features you'd expect on a high-end Android phone released in late 2018. It's got Qualcomm Snapdragon E45 processor, six gigs of RAM, 128 gigs of storage, a 1080p AMOLED display, dual rear 12 megapixel cameras and a 3200 milliamp hour battery. It also has a ceramic back and it supports wireless charging. It's running Android 9 Pie with Xiaomi's MIUI 10 interface on top of it and it performs just about as good as any other Android phone. The Mix 3 costs roughly $550 and like other Xiaomi phones, it won't be available in North America at all, so sorry. Now at first glance, this slide design addresses the problems of the notch and the hole punch display rather nicely. The Mix 3 has a completely uninterrupted 6.4 inch screen. It stretches all the way to the top and sides of the phone with just a slightly thicker border at the bottom. Now if you remember the Mi Mix 1 and the Mi Mix 2, the bottom is where Xiaomi put the front-facing camera but the Mix 3 just really doesn't have room for it down there. So in order to use the front-facing camera and take selfies, which on the Mi Mix 3 is a 24 megapixel sensor, it's got a secondary two megapixel depth sensor as well, you have to actually slide the whole front of the phone down about half an inch. That reveals the camera and it launches the camera app right into selfie mode. Now on this phone, the process is pretty quick. You push the screen down, the camera app launches right away and if you have the sound turned on, there's a little electronic sound effect that comes with it. Now snap the camera back up and the camera app closes automatically. You can even do it right from the lock screen so you don't have to unlock the phone to take a selfie. The Mi Mix 3 is a bit different than say the Oppo Find X or the Vivo NEX that have powered motors to raise and lower their camera module. This one here is all manual. It feels a bit like the old sliding keyboard mechanisms on messenger phones from a few years ago or maybe more recently the BlackBerry Priv. Give it a little push and a spring will help push the screen all the way down. All of that seems good but in practice, the sliding feature on the Mix 3 can be kinda awkward to use. Now this is a big phone, there's no getting around it and opening the camera one-handed without dropping it can be kinda hard to do. Now since you have to slide the screen down with your thumb, it's a little less natural than say the Priv which you pushed up to reveal the keyboard. You also have to move your pinky out of the way so that the screen can actually move down which again offers another way for you to drop it. It's just kind of awkward to do. Now on top of that, since you have to touch the screen to push it up or down, you might select something or open the notification shade or move an icon around on your screen without really intending to. Now you might be able to get proficient at doing this with practice but after a few weeks of using the phone, it's still super awkward for me and I'm constantly afraid of dropping the Mix 3 when I open the camera. Now there's other compromises with this too. The slider makes the phone thicker and heavier than other phones and you don't get a giant battery with that like you might expect with a thick and heavy phone. It's also a possible point of failure. It's not as delicate as the motorized mechanisms on the OPPO or Vivo but it's definitely more moving parts than say an iPhone and it could certainly get jammed up if you get enough dust or gunk in there. It also means that it's hard to make a case that fully protects the whole phone. Now Xiaomi includes a simple plastic snap-on case in the box with a cutout for the bottom for the screen to slide down but I wouldn't really expect there to be many other options available and that's gonna be kind of a running theme with these designs. That means that even though this sliding design eliminates the compromise with the notch, it introduces a lot of other compromises that in my opinion are worse. Now fortunately, the Mix 3's back camera isn't hidden by the slider and there's a standard fingerprint scanner on the back so the only time you really need to use the slider is to take selfies but you still have to deal with a thick and heavy phone that has only average battery life and you have to worry about whether or not that slider mechanism is going to break someday. You have to really ask yourself how much do you hate the notch to prefer a design like this? For me, I'm gonna stick with the notch.
