Debut of the Samsung Galaxy S21 series, with changeable shooting and UWB positioning

Samsung officially announced its first flagship series of Galaxy S21 mobile phones in 2021. In addition to the ultra-flagship S21 Ultra, there are also two mainstream-oriented twin Galaxy S21 and Galaxy S21 + machines with similar specifications and looks, focusing on diversification. The trigger function and the UWB bandwidth positioning function.

The appearance design of the Galaxy S21 and S21 + is almost the same, because the camera modules on the back of the camera have the same three openings. Only by comparing side by side can you find the difference in size. The S21 measures 6.2 inches and the S21 + is 6.7 inches. The display panels of both mobile phones use FHD + Dynamic AMOLED panels, which automatically adjust the refresh rate between 48Hz and 120Hz. Yes, comparing the S20 series they all have Quad HD + resolution and 120Hz attributes, the S21 dual machine seems a bit “downgraded” this time. However, considering that 5G will consume more power, and everyone may prefer to sacrifice high pixels for a more sensitive high refresh rate, so FHD + / 120Hz may be the best solution in mainstream mobile phones.

Speaking of endurance, the battery capacity of the Galaxy S21 is the same 4,000 mAh as the previous generation, but that of the S21 + will go up to 4,800 mAh. I think the usage time will be considerable, depending on whether there will be an opportunity to measure it later. The Samsung Galaxy S21 series packaging box will no longer be accompanied by a charger and headphones. Only the charging cable comes with the phone. If necessary, you can start it separately. The S21 series is equipped with 5nm process processors, estimated to be Qualcomm Snapdragon 888 and Samsung Exynos 2100. RAM is unified at 8GB, supplemented by 128GB and 256GB of storage space.

The specifications of the Galaxy S21 and S21 + cameras are the same as the previous generation. All are based on 12MP wide-angle, combined with 12MP ultra-wide and 64MP telephoto cameras to achieve up to 30 times the hybrid telephoto effect. Like the S21 Ultra, the S21 and S21 + will have the Zoom Lock function to stabilize the 30x telephoto image, and there will also be a “director mode” that displays all cameras at the same time.

Lastly, there is the functional difference between the two S21s. The Galaxy S21 and S21 + are not only different in size and battery, but the larger S21 + also supports over-band positioning. Both mobile phones have SmartThings Find positioning functions, but the S21 + with UWB can be used with the new SmartTag + for clearer direction positioning when searching for objects.
