The Samsung Galaxy A51 is the successor to one of the most popular phones of 2019... So, naturally, my expectations for this device are very high, and that's why I've put it through its paces to find out how it fares in the new decade. Much like its other A series brethren, the Samsung Galaxy A51 has a beautiful OLED screen. It's 6.5 inches across and has a resolution of 1080×2400 pixels. There's no edge to edge action happening over here, and instead, you have to settle for a flat screen, which is perfectly fine for your video watching and gaming needs. The punch hole for the 32 MP front camera is also less distracting than the Infinity-U notch so it’s really not going to bother you. Additionally, the in-display fingerprint sensor isn’t as fast as a physical one, which is why it can take a bit of time for the sensor to register the print.
