Samsung has announced that currently it has no plans to update Samsung Galaxy Ace 4 to Lollipop. The Galaxy Ace 4 was announced last year and was released a couple of months later.
This information about Galaxy Ace 4 has been shared through twitter. However, the official source did not mention any reason behind the cancellation or delay of the update.
This has come just after UK carrier Three announced that it won’t be updating Galaxy S4 Mini to Lollipop due to memory limitations. However, the Ireland carrier rolled it out some time after the announcement.
