1. HARDWARE/SOFTWARE
Typically, smartphones made by apple like the iphones are high in quality and performance. Since only Apple makes iphones, it has good control of the hardware and software including how they work together. Their smartphones are also unlikely to overheat.Android phones are a different story. It's hardware and software are used by multiple manufacturers like LG, Motorola, Samsung, etc. Because of this, Android smartphones vary in shape, size and weight. This means choosing your smartphone will be all the more difficult, first choosing the brand then the model. For example, the LG (brand) G4 (model). Unfortunately, in some brands, Android smartphones are more likely to overheat due to a poorer quality . We wouldn't want another Samsung note 7 incident anytime soon (insert sinister laugh here).
Some people like Apple's simplicity of choosing high quality devices while other may prefer Android's greater, inexpensive selection choice.
2. APPS
Apple and Android smartphones have their own little hubs to download apps being the App Store and Google Play respectively. You can usually find the same apps on both of these download hubs though some apps are made specifically for Apple and vice versa for Android. In addition, there will be some apps that will be available on both Google Play and the App Store but on different times. For example, an app may be available on Google Play now but weeks later on the App Store. Overall, the two download hubs are excellent at their job. The deciding factor will most likely be which apps will be available for download on which platform earlier.Personally, I prefer using Google Play more than the App Store simply because of the ease of access and colourful design. There will most likely be a separate review covering the more specific details of the two download hubs.
3. SECURITY
Apple and Android smartphones all have excellent security features to protect the precious smartphone you are going to buy. For example, lock screens, download confirmation buttons and advanced password options are available at your disposal. Want to unlock phone with face? Sure! Want to create a PIN number that's almost as long as the digits of pi that you'll probably never remember? Sure!
However, it is usually not those security features that fail when there is something wrong with your smartphone. Just like computer viruses, there are ones made to invade smartphones as well. Some download random apps without your permission while others restart your phone repeatedly or at the most random of times and some even do both! But how does any of the available features prevent you from downloading these viruses? To put it simply, they don't. The only feature that somewhat prevents this is a ineffective confirm download button. Not only that, almost all smartphone viruses are designed to be downloaded on Android smartphones due to the plentiful brands and models that use Android.
Because most smartphone viruses are meant to be downloaded on Android, it is far more safer to download random things on the internet using a smartphone made by Apple than on Android; not that you should... right? Not all is lost though. There are various antivirus apps available for download in the App Store or Google Play.
