Android is one of the most common operating systems specifically designed for mobile phones, smartphones and tablets. Now it is used by almost all manufacturers of this equipment. Any operating system is periodically improved and improved, its individual parts are optimized. Such corrections and improvements are an update to Android.
You can check for modifications yourself. To do this, go to "Settings", find the item "Software Update" and view the update settings that have opened. To check if a new version has been released, click the Update button.
Why do we need new OS versions
In fact, updating Android is a good and good thing, so you should not treat this with suspicion or skepticism. As a rule, improvements make using the device more comfortable and faster.
The Android update is available on a micro and macro scale. Minor enhancements have a capacity of up to 100 MB and are designed for individual parts of the system. They are small patches, the elimination of minor flaws that are even invisible to the user. The purpose of such micro-actions is to improve and stabilize the phone or tablet.
And larger innovations already weigh about 500 MB and affect the entire device. In fact, there is a slight change in the OS version. Such a large-scale update of Android software can also change the appearance of the system, making it simpler and more concise.
How does this happen
If your device does not have permission to receive updates by default, then every time a dialog box appears with a notification and a proposal to install something new. You can postpone the download and installation for some time (from half an hour to two hours) or refuse the update at all.
If you selected “Install,” the system will display a notification that the device will restart. Therefore, it is strongly recommended that you close all running applications and save the necessary information, otherwise it will simply be lost. Immediately after notification, the device turns off, the screen goes blank. After a couple of seconds, an image of a typical android robot appears on it, and at the bottom of the screen you will see the progress of the update process in percent. On average, Android updates take from 5 to 20 minutes, after which a reboot occurs.
When the device turns on again, applications are optimized in it to work correctly with installed updates. The number of such applications is displayed. After this last action, a notification about the successful update of the device appears. It is recommended that you restart it so that all programs start working normally.
What are the problems after
As a rule, none. After the update, some applications that are not compatible with the new version, or individual icons from the Desktop may disappear (for the same reason). There is also the appearance of new programs in the device, which will be impossible to remove later - this is provided by the developers.
As a rule, problems arise only if the Android firmware was performed independently or unofficial software versions were used. And the guarantee for the same reason is lost, so a lot of money will have to be spent on bringing the device back to life.
How to return the old version
When you do not like the updates received, then there is a natural desire to "return as it was." But, alas, such an opportunity is not provided. Unless it comes to your mind to manually change the firmware, but this is better not to do. Why? See the previous section. It’s better to take a closer look at the new version of the OS - maybe you’re just not used to it yet, and in a couple of days you’ll already love all the changes.
