Selin you mean for the (a) series right? Because the Phone (1) and Phone (2) both housed Snapdragon SoC’s.
Phone (1) used the Snapdragon 778G+
Phone (2) used the Snapdragon 8+ Gen 1
And I’m super excited that Nothing continues to use Snapdragon with the (4a)'s!
Connectivity, Power Efficiency and Performance are what I look for in SoC’s and you do not get better than Snapdragon.
