Samsung Galaxy M40 latest update bring improvements to facial recognition and camera


Galaxy M40 or Galaxy M51

Samsung is rolling out a new update for the recently released Galaxy M40. The update isn’t as a big as a new Android version, however, it’s still an important one. After all, it’s an update that comes packed with improvements to the camera and facial recognition.

Worth noting that the new firmware also bumps up the security patch to June 1. That’s a bit disappointing considering that we’re walking to mid-July. However, it’s still better than being two months behind in security terms. The firmware carries the M405FDDU1ASG2 build number and measures 378.40MB.
