Series 30

The Series 30, often shortened as S30, software platform is an application user interface created by Nokia for its entry level mobile phones. S30 phones are not capable of running Java apps. In 2014, Microsoft acquired Nokia's mobile phones business and discontinued S30 for its Nokia-branded mobile devices.

Despite its similar name, Series 30+ is an entirely unrelated platform, licensed from MediaTek and used on later Nokia-branded feature phones made by Microsoft Mobile; unlike the similar S40 platform, it does not support Java apps.

The first ever Series 30 device was introduced with the Nokia 1100 in 2003. Originally, S30 was supposed to have just one menu key, but a second one was added with the release of the Nokia 1110. All S30 devices also don't have a 5-way d-pad, only a 4-way d-pad (except the Nokia 1100 which just has a 2-way d-pad).

The following is a list of Series 30 devices released by Nokia:
