Update: IT turned out that the tweet was actually a mistake and it was since deleted. While Sony does plan to release 5G devices, the Xperia XZ3 has no equipment ready to handle the next gen networks. Here's the correction issued by the Sony press team.
We want to clarify an earlier tweet to confirm our Xperia XZ3 does not support 5G. Whilst we're not there just yet, we are excited about the future of 5G and Xperia.— Sony Xperia News (@SonyMobileNews) September 6, 2018
Move along then - nothing to see here.
Sony has confirmed that the Xperia XZ3 is its first 5G smartphone and possibly the first 5G ready phone to come to market.
5G networks are still not in use but once up and running will provide up to 2Gbps of speed. Qualcom's current X20 modem inside the Snapdragon 845 doesn't offer 5G speed, but the upcoming X50 modem (along with the X24 modem) will enable 5G support for phones coming in 2019.
It's logical to assume that the Samsung Galaxy S10 family will also bring support for 5G and we know Huawei is planning the same step for 2019.
SD835 also dont support 5G i have no information about that. And so i cant confirm whether you lie or saying truth.
