Samsung S5610

The Samsung S5610/11 (also known as Samsung Primo/Utopia) was announced in September 2011 as part of a range of feature phones released by Samsung. It supports smile detection, records video in QVGA at 30fps. It also has FM recording and SNS integration. A slightly updated version was released in March 2014 as GT-S5611 model. Both run on single-core CPUs ranging from 460 to 469 MHz. The differences are that the S5610 uses NXP's processor and has 108 MB internal memory, while the S5611 uses Spreadtrum's processor and has 256 MB internal memory. However, the S5611 lacks WAP 2.0 functionality and the usage of the camera LED as a torch.

There is also an Indian CDMA+GSM version marketed as Primo Duos, with the internal model number SCH-W279.

It has also gained additional popularity due to unlicensed and uncredited usage by James Bond in the film Spectre.
