Fake-5G: Samsung Galaxy S20 Ultra in JRE teardown without mmWave 5G antennas

Im JRE-Teardown zeigt sich, dass nicht alle Galaxy S20 Ultras aller Länder das gleiche Featureset bieten. Hier fehlen die mmWave 5G-Antennen.The JRE teardown shows that not all Galaxy S20 Ultras of all countries offer the same feature set. The mmWave 5G antennas are missing.

(Update: Even in Europe without mmWave support?) The inglorious saga of Samsung's sometimes rather shady marketing promises regarding the Galaxy S20 series and the Galaxy Z Flip continues weeks after the launch. The teardown of the JerryRigEverything Youtube channel shows that in some regions, specifically South Korea, Galaxy S20 Ultra models are delivered without mmWave antennas and thus only the slower Sub-6-5G is supported, as with the base Galaxy S20 5G.

There have already been two teardowns of a Galaxy S20 Ultra: the official one from Samsung itself and the repair profile of iFixit - so what should be discovered exciting with the third deassembly of the JerryRigEverything Youtube channel, which is not already known anyway?

Missing mmWave 5G antennas

That is how you can be deceived. Up to minute 10, the video of Zack Nelson (see below) is indeed worth seeing but not exactly a sensation, but after that it becomes more than exciting. Because where the other two teardowns reveal the three separate mmWave 5G antennas, the tester's Galaxy S20 Ultra 5G has a yawning void.

Missing nets as an argument?

Zack speculates that his model, purchased from South Korea, does not include high-frequency antennas because korea lacks the corresponding networks, i.e. only the more extensive but slower sub-6 frequency bands are active. This may be the case at the moment, but it does not have to stay that way in the future, and a South Korean might expect to be able to use the mmWave networks in the US and elsewhere with his not exactly cheap 2020 Samsung flagship.

Intransparent product pages

The fact that Samsung is taking some features, especially space-hungry as mmWave antennas, from the smaller and cheaper Galaxy S20 variants is perhaps still understandable - but with the Galaxy S20 Ultra, which costs 1,350 euros to 1,550 euros in this country, it should probably be really all there and not further slimmed down regionally. Moreover, Samsung's own websites are highly opaque not only in this matter. The official regional product pages do not provide detailed specifications for the individual models.

Here are the concrete specs

Only those who take the trouble to search on Samsung's global or German press pages will find what they are looking for in terms of Specs. We have only foundhere about the following regarding the Samsung Galaxy S20 Ultra in Germany :

To help users take full advantage of the new technology, every Galaxy S20-series smartphone, consisting of the Galaxy S20, Galaxy S20+ and Galaxy S20 Ultra 5G, is equipped with the latest 5G technology. The Galaxy S20 Ultra 5G is compatible with both low-frequency bands and high-frequency bands, while the Galaxy S20| S20+ low-frequency bands to connect to the 5G network.

This suggests that at least the Galaxy S20 Ultra is equipped with mmWave antennas in this country, but not the 6.7 inch Galaxy S20+. By the way, this is different in the US market, where only the small Galaxy S20 5G does not seem to offer mmWave support after reviewing the specifications in the global pressroom, but Galaxy S20+ 5G and Galaxy S20 Ultra 5G both seem to offer no mmWave support.

For security reasons, we have made a request to Samsung Germany to confirm that the Galaxy S20 Ultra actually supports millimeter wave 5G in this country and is also delivered with the necessary antennas. After the already known scandals around "fake glass", "fake zoom" and " fakeslow motion" the partly "fake-5G" is definitely not an award for the Samsung marketing team.

Update 20:00 But no mmWave support in the German Galaxy S20 Ultra?

Unfortunately, an initial response from Samsung Germany leaves us even more perplexed than we already were. The answer suggests that Galaxy S20 Ultra models sold in Europe are only equipped with sub-6 support up to about 3.8 GHz - the Samsung spokesman justifies this on the grounds that there are no corresponding mmWave networks in Europe and that the Federal Network Agency also does not provide any.

However, this would be a very short-sighted attitude, because mmWave networks in Europe are planned for the end of the year or 2021 and a Galaxy S20 Ultra bought today for more than 1,300 euros could not use them, if this statement is correct. So something else would be certain for the future. In addition, as a buyer of a German Galaxy S20 Ultra, you may also want to log in to US mmWave networks to use the short-wave download speeds of up to 1 Gbps - that wouldn't work either.

The Samsung Exynos modem 5123, which is used in the European Exynos 990 version of the Galaxy S20 Ultra, basically supports bothSub-6 and mmWave, so it can't be because of that. There is something else that is swirling around us. Not only do samsung product pages not provide any data sheets on the configurations actually delivered in the respective country, Samsung Germany also indicated that the press release linked above appears to be only a translation from English and therefore incorrect.

However, this cannot be true, because the text differs between German press release and the global Samsung Newsroom by diverging technical information, see picture below. We are sticking to it. In any case, Samsung provides plenty of criticism, the lack of clear, detailed data sheets on the websites alone, and the resulting lack of transparency in the apparently quite dramatic differences between Asian, American and European models are more than shameful for the number one in the smartphone market.
