Samsung Galaxy S3 and Note 2 smartphones will not receive an upgrade to Android 5.0 Lollipop, the latest version of Google's mobile operating system.
Samsung revealed the news on Twitter in response to a tweet requesting information about the possible rollout of Lollipop to the smartphones. The tweets below show Samsung UK's answer.
The decision not to push Android 5.0 to the smartphones, which are now several generations old, could be designed to prompt customers to buy the latest Galaxy S6 handset.
Buyers who are keen to get their hands on the latest version of Android can opt for the third generation of the phablet, the Note 3, which Samsung confirmed will receive an upgrade to Lollipop.
"We can confirm that the Note 3 shall be receiving the update. We'll be sure to let you know as soon as it is ready," the firm said.
But Samsung did not indicate when the Note 3 would receive the upgrade. "Unfortunately we would not be able to give you a time frame. We really do apologise for this," it said.
Samsung may be apologetic, but users of the older smartphones could be stuck on KitKat for longer than they want, which in turn could prompt them to purchase more recent Samsung models.
Samsung would no doubt welcome this, as a report from Reuters said that the company has not shifted as many Galaxy S6 handsets as it would like, forcing the firm's investors to lover earnings expectations for the second quarter.
Samsung has denied that it is suffering from less than stellar sales of the smartphone, and analyst firm Gartner debunked the talk of weak Galaxy S6 sales.
However, the release of the Galaxy S6 failed to improve Android's UK market position, leaving Apple's iOS to capture an increasing share.
The performance of the Galaxy S6 is still significantly better than the examples in V3's top 10 quirky smartphones that stand out from the iPhone and Android crowds.
