Swappa's phone valuation experience now exists in app form

There are plenty of ways to sell your phone when you decide you're ready to move on to something new, and since some of us experience to urge to swap phones a whole lot more often than others there's usually some research needed to determine the best price to list your hardware. Researching this kind of thing can often be a lot of work, since listings usually disappear as soon as the transaction is complete, and in many sites there are private conversations that can have a significant effect on the final price tag.

The folks at Swappa have been doing this whole third-party smartphone and tablet sales thing for a while now, and one of the best tools on their website is the record of what devices have sold for in the past. That experience now exists in app form, so you can quickly see what your phone or tablet would be worth when considering selling it. The app is called Swappa Price, and as the name suggests it's all about letting you know what other devices have sold for on Swappa. Like the Swappa site, you can break things down by carrier, unlocked, and if you've decided you're interested in buying or selling based on that information you can tap either of the big friendly buttons in the search results and be taken to the Swappa site.

It's fairly simple stuff, but for folks who are constantly buying and selling phones and tablets in the search of something new this app can reduce a lot of the research time. Enjoy!

Head to head: ASUS ZenFone 2, Alcatel Idol 3 and Huawei P8 Lite

All three of these phones are great, but which one is the best of the best?

Nobody is happier about the way the inexpensive and unlocked phone landscape has improved in 2015 than we here at Android Central are. Well, maybe Google is — the best of the best all happen to run Android.

Motorola once ruled this entire space with the Moto G and Moto E, and while they were good phones (and still best in class when looking for the absolute cheapest way to get a smartphone) the new crop from ASUS, Huawei and Alcatel take things a notch higher in price, performance and usability.

We had to get what we consider to be the best of 2015's unlocked, value-conscious phones together and do a bit of comparison.

We've looked at these three individually, and reviewed them in-depth. That's where you should probably start, so here's some reading to get you started.

Snapchat gives your finger a rest in latest update

Snapchatters, there are some big improvements coming to everyone's favorite ephemeral messaging app. Perhaps the biggest change hitting Snapchat is that users no longer have to hold their finger to the screen to view snaps — something people have been asking for for a while.

Here's what you can do with the 'Active key' on the Galaxy S6 active

Outside of the rugged hardware, there isn't a ton that separates the basic use of the Galaxy S6 active from its standard counterpart. The one notable exception is the extra hardware button — the "Active key" — found directly above the volume rocker on the left side of the phone.

It's tied into a new bit of software found exclusively on the active version of the device called the "Activity Zone," which is a neat little dashboard for all things active on your phone. But the Active key can also be customized to launch other apps of your choosing.

My shameless addiction to Vainglory, and its effect on how I game

It's not a new game, but Vainglory introduced me to a whole new way to enjoy playing on my mobile devices. It also got my hopelessly addicted to the genre. Again.

For me, mobile gaming has always been about filling the time normally spent awkwardly waiting for something. A quick time suck while in line at the store, or out in the car as my kid finishes up practice. Every once in a while, something grabs my attention and I play it during other points in my day, but the core gameplay mechanics are the same and I can stop whenever I need to get up and do something.

Vainglory is nothing like my normal mobile game. It's a online game that forces me to sit down, block out at least half an hour, and focus intently on a larger mission. When the beta for Android started a couple of months ago, I wanted to see what it was like to immerse yourself in a mobile game in the same way I would a PC or console title. The genre is most commonly known a Multiplayer Online Battle Arena — MOBA for short — and is usually something I'd prefer to play at my desk in front of my rather powerful gaming PC. Instead I find myself curled up on the couch tapping away on the screen for hours at a time, and I'm unlikely to stop anytime soon.
