Verizon's Note 10 5G tests confirm the audio jack's demise with official schematics
Said phone is none other than Verizon's 5G version of the Galaxy Note 10, and the tests, unearthed by Droidlife, include Samsung and Qualcomm input, as both are 5G modem suppliers for the handset, depending on which chipset it is using.
Among the mmWave and Verizon's 5G Ultra Wideband n260 (39GHz) and n261 (28GHz) frequencies parlance, one would be forgiven to pay the most attention to the actual 3D CAD renders of the Note 10. Since these are coming straight from the manufacturer, they kind of serve as an official confirmation for the first demise of the audio jack on a high-end Samsung phone.
Other takes from the Verizon's Note 10 5G testing is that the phone is compliant with the radio emission limits of the FCC by using something Qualcomm calls Smart Transmit that scales down power when the emission levels start getting out of hand.
It is aided by smart antenna placements that prevent interference and excessive heat, just this small paragraph can tell you what goes on behind the scenes of fine-tuning 5G connectivity on the Note 10.
