Update guarantee
The update guarantee is a manufacturer's promise to supply a device with new Android versions and security updates for a certain number of years.
What does Update guarantee mean?
Two things need to be told apart: new versions of the operating system with new features, and security updates that close vulnerabilities. Some manufacturers give the same number for both, others different ones.
Long commitments are mainly common in the high end, while cheaper devices often get less. The longer the commitment, the longer a device can be used safely and the easier it is to sell later. That does not mean that all new features also reach older hardware.
A general explanation of the term, not from a video. How it plays out on a specific device in everyday use is covered in the reviews below.
