Samsung Galaxy M51 Specifications
Samsung is a pioneer in displays, and they are not holding back with the M51 either. We get a 6.7-inch FHD+ Super AMOLED Infinity O display with an aspect ratio of 20:9. The selfie camera is housed in a small center punch hole at the top. The peak brightness is a bit low, though, at just 420 nits. And we only get the dated Corning Gorilla Glass 3 protection in the front. Under the hood, we get the capable Snapdragon 730G, which is a bit old but still a competent processor. It can handle most games and heavy-duty tasks easily.
With the Samsung Galaxy M51, we also get Android 10 onboard running on top of One UI 2.1. And we get two RAM options with this device, a 6GB base variant and an 8GB upper variant. The internal storage remains the same at 128GB. In terms of optics, we get a quad-core setup at the back with a 64MP Sony primary sensor, a 12MP ultra wide-angle sensor, a 5MP depth sensor, and a 5MP macro sensor. On the front, we get a 32MP selfie shooter. The front camera support 4K video recording along with Front Slow Motion Video, AR Doodle, and AR Emoji.
The Galaxy M51 is not a 5G compatible device, and you get only 4G(LTE) here along with the other basic connectivity options like Wi-Fi, Bluetooth v5.0, GPS/ A-GPS, USB Type-C, and a 3.5mm headphone jack. You don’t get the modern In-display fingerprint sensor, though. Instead, you get a side-mounted fingerprint sensor. The base variant is priced well at 24999 INR, and the 8GB variant is priced at 26999 INR. And it will go on sale on the 18th of September at Amazon and Samsung.com.
