A software update is a modification of existing code that corrects security and functionality problems in programs. It can also improve a program’s performance or make it compatible with other programs. It can be applied manually or automatically by the manufacturer. Some updates are rated as critical and should be installed immediately. Others are categorized as important or moderate. The software publisher usually provides the update free of charge.
One of the most compelling reasons to keep your phone’s software up to date is that it can protect you from cybercriminals and viruses. Hackers can use old software to access your information or hijack your device to attack other devices and users. Newer software uses more effective protocols that are harder to crack and that can block many of the exploits used by hackers.
Updating your phone’s software can also give you exciting new features. For example, you can get health features that track your steps and give you accurate weather reports, or a faster operating system that enables you to download apps more quickly and easily. Your phone may also have improved voice recognition and more accurate face identification.
When a company releases an update to its mobile products, it should provide clear, concise, and detailed release notes that explain how the update works, what it does and doesn’t do, any known limitations or dependencies, and how it will impact the user experience. A good set of release notes can help users understand what’s being changed and decide whether to install the update or not.
