★ Our Verdict

The Samsung Galaxy M40 offered a modern display and capable performance for its price segment, but its LCD panel, smaller battery, and lack of a headphone jack were notable drawbacks.

The Samsung Galaxy M40, released in 2019, was a mid-range contender offering a modern Infinity-O display and a capable Snapdragon 675 processor. While its triple camera system performed well in good lighting, the phone's PLS LCD screen and 3500mAh battery were compromises compared to other M-series models featuring AMOLED displays and larger batteries. The absence of a 3.5mm headphone jack and the hybrid SIM slot were also points of consideration for potential buyers. Given its age, it's unlikely to be available new, but if considering a used device, assess battery health and software update status (it received up to Android 11). For current buyers, newer models offer better value and features.
