Series 30+



Series 30+ is a user interface used on Nokia branded feature phones made by Nokia, Microsoft Mobile, and HMD Global, succeeding Series 30 and Series 40 in 2013-2014.

S30+ is based on MediaTek MAUI. Java applications are not supported, with a few exceptions like the Nokia 222 and Nokia 230 on 2016 firmwares as well as Nokia 216, but some models support MRE.

Later S30+ phones, such as the Nokia 105 (2019), 110 (2019), 215 4G, 225 4G and most other models released since 2020, are based on a Unisoc chipset, using Mocor OS instead of MAUI. These can be identified by the bubble keypad sound and SONiVOX MIDI synthesizer.

The UI shares many similarities with S40, but with a simpler design. Supported screen resolutions are 120×160, 128×160, and 240×320.
