Samsung's latest flagship Galaxy Note 10 and Note 10+ have started receiving software update for September 2019 security patch from Verizon and T-Mobile.Two weeks earlier, Sprint had released a similar update which the build number is N97*USQU1ASHB for the updates on all three carriers.According to SamMobile , the update includes improvements to audio quality over wired earphones, for the T-Mobile devices. Meanwhile, Verizon doesn’t list the audio improvements on its support page for either the Note 10 or Note 10+.Hence, this September update for the Note 10 and Note 10+ on T-Mobile and Verizon can be downloaded via OTA “over the air”. To download it, simple navigate to your phone Settings and scroll down to Software update menu.Undoubtedly, the OTA release can can take some time to reach all users, so if you don’t see any update right away, you should just try again after some time. Hence, you can as well flash it manually if you can't be able to wait and thus, you need a PC to achieve this.
