Network services is poor on samsung M40. Wifi connection working good but sim network doesn't work properly in 3G/4G . Is anyone facing this problem?Any solution here?
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 light...
Well, there are some Battery problem issues or short circuit problems. I mean hardware problem. If you had warranty of those buds, you may contact Samsung service centre otherwise there are nothing to do.
