Samsung M40 has many problem by Its current firmware version. Need a better firmware Update for its solution. Led notification function isn't  working. Fingerprint sensor sometime missed to unlock phone, when i press the power button and screen lights turned on then fingerprint can work. And many functions isn't here, where i used those options or functions in lower priced phones for example Samsung galaxy j7 (2016). So basically it's unfair.
