Some potentially bad news for people thinking of purchasing an Samsung Galaxy S21, S21+ or S21 Ultra.
After watching the first video teardown of a S21 Ultra international version with a Exynos 2100 processor (https://youtu.be/cU3QXPoFOUI) I discovered an issue for me and maybe others. One of my conditions for getting a new phone was future proofing by getting a phone that would be compatible with the soon to be allocated mmWave 5G spectrum of 26 GHz and 28 GHz bands in Australia. In the video it is shown that the international version of the S21 Ultra does not have the required mmWave antenna — these antenna are however present in the Snapdragon version.
I contacted Samsung Australia, regarding this and I received the following: "The latest Galaxy S21 range of devices do not support mmWave in Australia. For the Galaxy S21 range, supported bands will be 5G Sub 6 FDD and 5G Sub 6 TDD. The mmWave band is only available in US and Japan markets. At the moment, Samsung Australia will also be unable to offer any form of repairs to make it compatible for mmWave as it requires special equipment to re-calibrate RF after device dismantle."
I hope this information is of use to some, I don't think I will be purchasing a device that is inferior to its other versions.
