AT&T has updated three smartphones from Samsung and LG to make them show 5G connectivity logos, even though none of them are capable of connecting to 5G networks.

Now, when the Samsung Galaxy S8 Active, LG V30, or LG V40 are connected to portions of AT&T’s LTE network that have received some speed-boosting updates, they’ll show an icon that says “5G E” instead of “LTE.”
