Review on Samsung Galaxy S20 FE G780G 4G Dual 128GB 8GB RAM Factory Unlocked International Version - Cloud Navy (GSM Only) by Ninh Quang Truong ᠌

These problems concern the phone on Exinos. 120 hertz is pure marketing. In this mode, the charge melts before our eyes. With even the slightest load (working in several applications, installing or ating applications, maps, navigator.), The processor heats up and the phone automatically resets the screen to 60 Hz, after cooling it returns back. And such swings occur many times a day, if you actively use the phone. I switched to constant 60 hertz for the sake of saving charge, in general, I did not suffer from this, BUT ! For some reason, the fingerprint scanner works well only in 120 hertz mode, at 60 it's a complete torment. Works through time, and even less often. Logging into banking applications and others where biometric fingerprint authorization is needed is just a nightmare. Very often the case ends with a password. It turns out a vicious circle with a display refresh rate and a fingerprint scanner. I tried all the methods known on the Internet to improve the performance of the scanner, but nothing helps. At 60 Hz, the scanner can be said to be unusable. This is confirmed by other users from popular forums. Because of this problem, someone even manages to return the device. The devices on the snap do not consider these problems. The percent is less heated, hence there is less swing with a hertz screen. The scanner works fine and at 60 Hz. The screen time of the smartphone is noticeably longer. In general, if you want this device, then take it only on a snap, but in 2022 these are gray phones with all the consequences. Otherwise, I don’t advise you to take this raw and stillborn product at all.
