Honor 10 will have a 3.5mm audio jack like the P20 Lite and Honor View 10
The Honor 10 is no stranger to the rumor mill, but there still are new details coming to light every day. The phone will use the same 5.84 LTPS display panel as the Huawei P20 Lite, including the notch. The selfie cam in that notch should be the 24 MP module from the P20 and P20 Pro (the Lite model comes with 16 MP).
The mix of features continues with a 3.5mm audio jack, unlike the Huawei P20 and P20 Pro.
Unfortunately, the Honor 10 will miss out on expandable memory it will not have a microSD slot like the P20 Lite and Honor View 10 do. It will use the Kirin 970 chipset, however, which places it between the Lite and the View specs-wise (and probably price-wise).
