Everything you need to know before buying a smartphone

I love buying new smartphones. Who doesn’t get a rush from buying the latest, coolest tech? Especially when it’s a device you’re going to use as often as your handset.

But when I head to the store, or, let’s face it, search online, there are a few very important things I keep in mind. Because like everything else in life, buying a new smartphone can be a lot more complicated than it seems.

If you follow these four tips and do a little research, though, you’ll be back home staring at your new phone and ignoring your friends and loved ones, just like me, in no time.

Before you leave the house, you’re going to have to answer one incredibly important question: What phone do you want? Are you an iPhone fan? Want the newest Google Pixel? Interested in Samsung’s latest offering? Looking at an LG, OnePlus or the Essential Phone? If you don’t know, you’ll need to make like Summer Sanders and figure it out.

How do you figure out which handset to buy? Well, if you’ve already got an Android phone, chances are you’ll still with an Android phone. If you’re an Apple (AAPL) fan, you’ll probably stick with the iPhone. If you want to take a chance and switch from Android to Apple or vice versa, though, you’ll need to take a few things into account.

The vast majority of your existing apps will easily carry over from iOS to Android and Android to iOS, but it’s good to understand that Apple’s handsets usually get new apps before Google’s (GOOG, GOOGL) Android. The iPhone also usually gets updated apps before Android-powered devices. The reason for this is simple: the iPhone has a larger install base in the U.S., so developers are going to build their apps for the platform with the most users first.

If you’re not sure what kind of phone to buy, there are a few specific features you should focus on: screen size, battery life, camera performance, overall performance and, most important of all, price.

Which carrier should you choose?

Many people already have a preferred carrier that they stick with each time they buy a new smartphone. And that’s fine. If you’re happy with your service and the price of your plan, then stick with it.

But if you want to move to a different carrier, the first step to take is to make sure that its service is reliable in your area. Ask your neighbors and friends if they experience connectivity problems near home. Check in with your coworkers to see if they can browse Snapchat (SNAP) and Instagram (FB) without any issues in the office. You’re going to want to think of the places you spend most of your time, and then see how service is in those areas.
