Not so long ago you said “cellphone” and meant a device that make calls and send texts. It was a simple thing with only one purpose: to make phone calls easy and portable. Even at that time it was one of the most popular device type on the planet except maybe a PC.In modern works each and every person has a smartphone or/and a tablet. People use them for everything starting from regular phone calls, creating grocery lists, writing messages, browsing web to making it their main work station for drawing, editing documents, creating music and having meetings. For some people a portable devices like smartphone or tablet is the main way to communicate with outer world.Same with PCs - everyone has them, everyone uses them, they are everywhere and this is not going to change.That is the reason a whole industry of app development has appeared and grows day after day.And on market with such high density there is no room for low quality products, which makes requirements very strict, and one of the main of them is to make sure your app works seamlessly on as much devices and platforms as possible.Here is a base information you need to know when thinking of cross device testing, what to use and how you should do it.
This one is pretty straight forward. There aren't much operating systems and screen resolutions so it will be relatively easy to test your website on them. Here are the basics:• PC. Windows 10 is one of the most commonly used platforms with screen sizes ranging from 20” to 24” desktop monitors with screen resolutions 1024x768, 1366x768 and 1920x1080. Of course, those are just the most popular ones that are easily available and make the most sense to test on.• Desktop Mac. Lots and lots of corporations use desktop 27” Mac as main workstations for their employees. They are sold with Retina displays that is a brand name for screen resolutions. They are extremely popular among a large variety of users both for work and at home, so if you are developing an enterprise app you certainly should test on Mac• Laptops. There is a vast amount and variation of laptop sizes, but most popular ones are 14” and 15.6” screens, you can call those a standard of some sort. They all feature 1366x768 resolution by default.
• iOS phones. Apple`s market share in US is about 30 to 40% of all smartphone market and about 15% of all world`s smartphone market. Although the second index does not seem very large from the first glance, if you think about it you will understand that either you have an iPhone or a person sitting next to you has it. So it's crucial to test your website (and obviously your native iOS app) on a number of iOS powered smartphones. You will need to test with iPhones from 5s to 7 generations (iPhone 5s, 6 and 6 Plus being most popular around the world at the beginning of 2017) and at least iOS 9.x, 10.x and 11.x OS versions.• Android phones. They are literally everywhere. There is almost infinite variety of devices and screen resolutions, which makes its absolutely impossible to test all of them so as always we recommend you to stick to most popular ones. Pick one of each top manufacturer and this should be enough: Samsung, Huawei, LG, Lenovo, Motorola, Sony, Xiaomi are at the top so far in 2017. As for OS versions it's easier: 6.x is at the top, then 5.x and 4.x. Also remember that Android 7 came out not so long ago so almost any new device come out with Android 7 or will get an update in the near future.
• iOS tablets. iPads are the absolute kings of this field with 25% of worldwide market share. They will be relatively easy to check since there are only 3 screen sizes on the market at the moment 9.7” being most popular of them and it has been since first iPad came out, followed by 7.9” iPad Mini and 12.9” iPad Pro. OS versions priority is same as for iPhones.• Android tablets.There are a lot of manufacturers that treat their customers with a huge variety of screen resolutions, so we recommend you to stick with most popular manufacturers being Samsung, Huawei and maybe Amazon. Android versions priority is also same as for Android phones, but less Android 7.x devices on the market.• Windows Surface tablets. The idea on of a half laptop half tablet device is growing and it also has its own place on the market, so if you want your website to have a true multi-platform status you may want to consider testing on those, especially since there are not as much manufacturers on the market: Asus, Lenovo and Microsoft are the largest of them, they all use Windows 10 and screen sizes from 10” to 13.5”.
