Overview
SUPPORT SMARTPHONE OPERATING SYSTEM UPDATES
A major goal for Smartphone operating system software updates is to get the updates and
security fixes installed on smartphones as quickly and as smoothly as possible without
interfering with the usual running of the device and the mobile network – to balance security
needs with usability.
There are many stakeholders involved in the process of developing, testing, distributing and
installing Smartphone operating system software updates. These include the operating
system developer (the platform owner), the Smartphone manufacturer (device OEM), the
MNO and the Smartphone owner. This process is represented in figure 2.1 below.

MNOs (MNOs) are an important part of the Smartphone operating system update process.
The majority of Smartphones purchased in the UK will be made through an MNO and as
such they will have a role in the operating system update process.
From a consumer point of view, the MNO will usually be the first point of contact for any
support contact that they will make as a result of a problem with a mobile device, including
operating system updates and patching issues.
The role of the MNO in supporting Smartphones on their network can include Smartphone
operating system customisation, where this is permissible. In the UK, Smartphone
