What are these icons in Tetra Lockscreen screeshoots?

[Windows Central Question]

Hello.

I think Microsoft published a very odd screenshot of Tetra Lockscreen app where BT, Wi-Fi and a unknown icon are in the middle. This app is supported only on WP 8.1 and up which eliminates WP 8.0 (because 8.0 had BT and Wi-Fi in the middle).

May this be a Windows 10 mobile tease or something else? Perhaps they do support WP 8.0 or is there a way to have these icons in the middle?

Thanks,
Jernej Kavka

That was the WP8 screenshot, the strange bell icon looks to me like a ringer/vibration indicator. W10 already showcased icons on the left top corner
