The One UI 2.0 Beta with Android 10 for Galaxy Note 10 & Note 10+ phones are coming soon to the USA & Germany. The official Samsung team has posted the banner on the forum of the Samsung community and revealed it. Yesterday, the official banner has posted in South Korea about the announcement. The post on the Korean Samsung community also mentions Galaxy Note 5G series will also get the Android 10 Beta version in the coming days.
In both the countries Unlocked users will first get a chance to test the Beta version before other carriers. In the US, Sprint & T-Mobile Galaxy S10 customers were lucky to install the beta version in the first phase, but for the Galaxy Note 10 series, it is only unlocked users. The customer executive at Samsung Germany has mentioned that Samsung will open One UI 2.0 based Android 10 Beta on October 24. If this is true, then tomorrow (Oct 24) we may see launching banner with register link in the Samsung Member app.
To join the Beta program, first, register to the Samsung Members app. On all Samsung smartphones, the Samsung Member app comes pre-installed. If not then download it from Play Store. Last time, the Beta version for Galaxy S10 was available only for limited users. It is not clear for Galaxy Note 10 users whether it is available for all unlocked customers or only for the first few customers. The launch date will be announced on the Samsung Member or community forum in the coming days. You can refer to the below links of Samsung communities in both countries.
