The OS It is the software that every mobile phone has, if we are to consider the most widespread of all is Android, followed from afar by iOS and then in the background comes Windows Phone. In many mobile phones, updates allow us to change the version of the operating system, often improving it in a notorious way, some do not allow us to change anything at all.
Change mobile operating system
In my personal case, recently my Samsung Note 5 changed to the Android 7.0 Nougat version and the change was really surprising, it seemed a different OS than the one I had, obviously with a change of interface and even operation in some things, the battery worked a lot better, its autonomy was different and the fluidity of the operating system in general had improved considerably, that kind of changes is simply beastly.
In the case of Android operating system It depends a lot on the phone you have, since in some cases you can have several versions of Android that have been released and in turn you can use Custom ROMs to even further improve the phone with different versions of Android that are considerably different from each other.
The issue is that as it is said to change, change, actually a mobile that comes with Android, with Windows Phone or with iOS, especially in these last operating systems, leaving aside the version, you cannot change the OS itself, you cannot have on a mobile with Android, iOS installed, it is impossible.
So basically you have to settle for the OS that you have now installed on your device, the only thing you can do is simply cachange the operating system version With a newer one or in case you know how to install firmware you could do a downgrade to be able to lower the OS version and install a slightly older one.
How to change the operating system of my Android
In any case, you can also go to the part of Settings, Then in About my device and finally Update software and you will be able to verify if you have any pending updates to be able to change the operating system of your phone to a more recent one, although these generally appear automatically, it may occasionally not appear or you will delete the notification itself.
It is for now the only thing you can do if you want change the operating system of a cell phone either a Samsung Galaxy SGH 798 or a Nokia Lumia, etc.
