Updating your
android device, whether it is a smartphone or a tablet, is an important practice not only for the practical purpose of having new features and maybe even improvements, but above all to increase the security of your device.
In fact, every day vulnerabilities are discovered that can be exploited by malicious people to compromise or violate our devices. Therefore, the
android update assumes great importance.
Normally, android
updates are not released directly by Google, but by individual phone manufacturers. In fact, every company usually introduces specific improvements for their devices and many customizations. Updates for android devices are usually guaranteed for at least
18 months. Although it is not possible to find an update every month, it is good to periodically check its availability.
To check the availability of any
updates just go to
Settings ->
Software Updates and choose Download and Install

This way your smartphone or tablet will check for
OTA (over-the-air)
updates.
OTA updates are precisely those that can be downloaded directly from the device. Before
updating, it is advisable to check that the mobile phone is fully charged and it is preferable that the connection in use is WIFI so as not to impact the giga of your telephone plan. Then check that you have plenty of free space for downloading and
updating.
Normally, security
updates take up only a few megs (usually 100-300 MB), while
updates for new versions of android can be as small as 1-2 GB.
The
latest version of android is
Android 11, among the most important news we find the bubble notifications in the style of Facebook Messenger, improvements in artificial intelligence, a new shutdown menu, improvements regarding privacy, support for the brand new emoji 13.0 (well 62 new emoji), screen recorder with audio functionality.

Many phones are already upgradeable to

Before any update, especially when it comes to a version
upgrade, it is advisable to make a backup of your data. Each manufacturer usually provides backup solutions. For example for Samsung devices via the Smart Switch app.
What happens when the update starts? The mobile unzips the installation files and replaces and
updates all affected system files. The device will be restarted automatically and a nice animation with the android robot will show us the percentage of progress. Once installation is complete, the operating system will optimize the device's apps. This operation will take a few minutes, but in the end we will have our smartphone updated to the
latest version available and with the latest security
updates.
For more protection always make sure you also have a good antivirus such as Kaspersky or AVG (they can be downloaded from the Play Store).
