One of the best things about the latest technologies and the internet is they can be updated with time in terms of software which was no way possible back then. Today you have the power in your hand to buy a smartphone and then you get the latest software updates as a service and guess what your phone works like a new bought model.
This applies to all the smartphone brands available in the market. That people often search for iPhone 4 update to iOS 10. This is the drive of technology that made us starve for the latest versions of gadgets in terms of hardware and software.
But as everything comes with a limitation the same applies to this handy benefit of mobiles. The very basic idea behind this is the hardware of your device is responsible to accommodate the respective programs that make your phone run. Whenever your phone finds an update, it is these programs that get updated. And when you download these updates your handset starts working like a new one with the latest technology.
However, as I stated earlier if your device is not compatible with the latest version of programs then it will not update. It depends upon many features such as the processing units of your device, their RAM, and many more. So, when an update comes which cannot be supported by your device it stops to receive updates.
To make it easier let’s take an example of the iPhone 4 and see if we can update it to iOS 10. And the answer to this question is NO! Why because the iPhone 4 is as ancient as the Roman Colosseum. Its central processing unit is not capable to run iOS 10.
The last update is received was on 22 July 2019 for iOS 9 which actually dragged Apple to a controversy of providing bug-filled updates to the costly devices. Therefore, they have to start a downgrading window for people who updated their iPhone 4 to iOS 9. Yet, it is the only iPhone that received 5 iOS updates.
