AT&T rolls out Samsung Galaxy S8 Active, LG V30 update that adds 5G Evolution logo
In other words, “5G Evolution” is AT&T's enhanced version of 4G LTE, so it's not to be confused with 5G connectivity which will have a different indicator displayed on compatible smartphones.
Now, AndroidPolice confirms that the first smartphones to receive an update that adds the said indicator are Samsung Galaxy S8 Active and LG V30, two flagship smartphones that were launched on the market back in 2017.
There's a major size difference between the two updates. While Samsung Galaxy S8 Active's update weighs in at 123MB, the LG V30's is quite huge at 1GB. The former is also getting the December security patch along with the 5G E indicator, but that's about all we've been able to learn from the changelogs.
We expect other smartphones to be updated with the 5G Evolution logo, although AT&T hasn't named any of these devices, so your guess is just as good as ours.
