Activision testing controller support for Call of Duty Mobile
It's not just that much of the game's audience is coming from consoles, but playing a shooter of this caliber on a smartphone for many hours takes a toll on the player's fingers. Unfortunately, controller support was not available at launch, and it's not been confirmed for any future updates yet.
The latest update from the Call of Duty Mobile community on Reddit mentions controller support more than a dozen times and Activision addressed the issue with a direct answer: We hear you loud and clear that you want to know about controller support.”
The developer also confirmed that it's now testing controller support, but will not add it to the game until it's sure that it works as intended, so it can't commit to an ETA for the moment.
