The Samsung Galaxy M40 boasts of many features such as a hole-punch display and a vibrating screen for an earpiece. It features a bright and vibrant 6.3-inch full-HD+ PLS TFT LCD display.
It's powered by a Qualcomm Snapdragon 675 SoC. There's only one variant, which comes with 6GB of RAM and 128GB of storage. The latter is expandable but it's a hybrid slot so you can’t have two SIMs and a microSD card. One UI runs well and is based on Android 9 Pie.
The 32-megapixel primary camera at the back shoots decent pictures under good light, but in low-light, the autofocus is slow and images lack good detail. The 5-megapixel depth sensor works well for objects and pets. The 3,500mAh battery lasts all day on one charge, which is a good thing.
