HMD Global relies on a number ODMs like Foxconn (and its subsidiary, FIH Mobile) and Longcheer to manufacture its Nokia-branded Android smartphones. While the practice is certainly useful to keep costs down, it has unintentionally exposed the company's internal firmware hosting servers multiple times. For example, the pre-release Android 10 update packages for the Nokia 5.1 Plus and the Nokia 8 Sirocco have been leaked quite recently. The latter has now started receiving a stable Android 10 update across the globe.
Following the footsteps of the Nokia 3.2 as well as the Nokia 4.2, HMD Global has opted for a staggered update rollout plan for the Nokia 8 Sirocco to ensure a smooth transition. The Android 10 OTA should reach 100% of users across 43 regions that the company currently operates in by April 20th. The build itself (software version V5.120) comes with the April 2020 security patches and is about 1.4GB in size.
The Samsung Galaxy A30s, on the other hand, is also getting a stable Android 10 update with Samsung's One UI 2.0 software on top. The base version number of the new build is BTD1, which is now available for several regional models of the phone (SM-A307FN/GN/GT) except the American variant, SM-A307G. The Android security patch level (SPL) of this new firmware is March 2020.
The OTA is rolling out in batches, but users can bypass the queue and download the updated builds directly from the Samsung update server using tools like Frija. Samsung has yet to publish the relevant kernel source code on its website, though. They also skipped the bootloader version update so power users still have the freedom to downgrade their phones to older Android 9 Pie-based builds.
