Amazon has told owners it will soon stop supporting older Kindle models - a move which has left some users outraged.

In emails from the tech giant, affected users were thanked for being a “longtime Kindle customer” but told devices released during or before 2012 would no longer receive updates from 20 May.

The move will mean owners of older Kindles, including its earliest models such as the Kindle Touch and some Kindle Fire tablets, will be unable to download new e-books.

Amazon said it has supported affected models for years and their active users have been offered discounts to help “transition to newer devices”, but some have criticised it for making up to two million devices “obsolete”.

“I have a Kindle Touch that I’ve had since 2013, it works great, I bought a book on it a few months ago, and suddenly it’s obsolete,” one X user wrote in a post tagging Amazon.
