Samsung will continue launching three flagship smartphones with the upcoming Galaxy S21 series, just like the Galaxy S10 and Galaxy S20. Recently, the leaks started popping up regarding the 2021 Galaxy S smartphones. According to Sammobile, Samsung has started developing the firmware for the Galaxy S21 smartphones.

Obviously, the operating system will be based on the all-new Android 11. The 2021 flagship smartphones will be running on Android 11 based One UI 3.1 out of the box. Even the Galaxy S20 smartphones launched earlier this year came with One UI 2.1 based on Android 10.

Samsung started working on Galaxy S21 Firmware

The company is currently working on the firmware for three devices with the model numbers SM-G991U, SM-G996U, and SM-G998U. Moreover, these are expected to be officially launched as Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra. The firmware currently under development is for all the major carriers in the US and is limited to only 5G variants.


Looks like Samsung seems to skip launching the LTE variants of the Galaxy S21 smartphones in the US. Nevertheless, the major US carriers have already started offering 5G services, and all of them are now in the expansion phase. Recently, Samsung promised to offer up to three generations of OS updates for its flagship devices.

There might be no 4G LTE variants for the US market

With the extended software support, many new users will be using these devices for a longer duration. Compared to 5G variants, the 4G variants will become inferior in the next couple of years. Since there is no official confirmation, this early analysis must be taken with a pinch of salt.

Recently, the Chinese certification website revealed the battery capacities of the Galaxy S21 and Galaxy S21+ smartphones. The two certified batteries with the model numbers EB-BG991ABY and EB-BG996ABY come with a rated battery capacity of 3,880mAh and 4,660mAh respectively.


In real life, the Galaxy S21 and Galaxy S21+ could be coming with a 4,000mAh and 4,800mAh batteries respectively. In comparison, the Galaxy S20 and Galaxy S20+ sports a 4,000mAh and 4,500mAh batteries respectively. Additionally, the rumored Galaxy S21 devices could make their debut as Galaxy S30.

Samsung recently released the all-new One UI 2.5 with the Galaxy Note 20 series. By the end of this year, the company is expected to begin rolling out Android 11 based One UI 3.0 to its latest flagship devices, at least. In the next few weeks, Samsung might release the One UI 3.0 public beta for selected smartphones. Stay tuned!
