Detailed Description of the Samsung Galaxy S21 Ultra

Display & Outdoor Visibility: 6.8-inch QHD+ 120Hz Dynamic AMOLED 2X

The screen is a 6.8-inch Dynamic AMOLED 2X at 1440 x 3200. That is QHD+ at a high pixel density, so text and 4K video look clean. The refresh rate adapts up to 120Hz. The front glass is Gorilla Glass Victus. There is an always-on display. The camera island is the contour-cut block that sits proud of the back.

Samsung rated this panel among the brightest of 2021. In a lab test that year it reached well over 1,000 nits in automatic high-brightness mode, which is enough for midday maps in Nairobi if the film is not badly scratched. Because these are renewed units, look for burn-in and hairline marks on the island before you pay.

Processor & Storage: Exynos 2100 or Snapdragon 888, 128GB or 256GB

Samsung sold two chips. Many African and European units used the Exynos 2100. Some other regions got the Snapdragon 888. These are renewed, so we read About phone with you. Both chips are 5 nm flagship silicon from 2021. They still run WhatsApp, Chrome, camera, and most games. They run warmer than today's chips.

We sell 128GB and 256GB for cash. There is no memory card slot, so pick the storage you will live with. RAM is typically 12GB. The weekly plan on this page is listed for the 128GB Excellent grade. If you want 256GB on the same renewed plan, ask us on WhatsApp because the financier did not publish a live weekly for that size.

Camera System: 108MP Main, Real 3x and 10x Telephotos, 12MP Ultra-wide

All four rear cameras are real sensors. The 108MP main is the daylight workhorse. The 10MP telephoto gives true 3x optical zoom. The second 10MP periscope gives true 10x optical zoom, which is the one you use for a sign across the street. The 12MP ultra-wide covers rooms and groups. The front camera is 40MP.

Video goes to 8K on the main camera and 4K at 60fps across the rear cameras. Night mode is stronger than the S20 Ultra. The S21 Ultra can use an S Pen for notes and video editing, but the pen is not in a silo in the body. If a pen matters, confirm we have one to add, or look at an S22 Ultra where the pen lives inside the phone.

Battery & Charging: 5,000mAh and 25W

The battery is 5,000mAh. In published endurance tests from that year the phone lasted a long mixed day when the cell was new. Battery health on a refurbished phone varies, so we show the reading on the unit you pick.

Samsung rated wired charging at 25W, which is slower than the 45W label on the S20 Ultra and S22 Ultra. A 25W USB-C charger fills it in a bit over an hour. Wireless charging is on the spec sheet. The original box shipped without a wall charger, and a renewed pack may or may not include one.

Kenyan Network Connectivity, Audio & Software

It is a 5G phone. Safaricom 5G works where the network is live, then 4G on Safaricom, Airtel, and Telkom. Most units take two nano SIMs. Many also have eSIM. Check the tray and Settings on the phone you are buying. There is no headphone jack. Stereo speakers sit at the bottom and in the earpiece.

The phone launched on Android 11. Samsung promised three major Android upgrades and four years of security, which took most units to Android 14. Do not buy it expecting another long run of major versions. DeX still works on a monitor.

Buyer Guidance: What It Is Not & Alternatives

Know what it is not. Every S21 Ultra on this page is renewed. The S Pen is optional, not built in. Charging is 25W, not 45W. There is no memory card slot. Software is near the end of the four-year promise.

The Samsung Galaxy S21 Ultra price in Kenya is the 2021 way into 108MP with real 3x and 10x zoom. If you want the pen in a silo, look at the S22 Ultra. If you want a later Ultra with seven years of updates, look at the S24 Ultra.

We sell genuine units from The Bazaar Plaza, Moi Avenue, 10th floor, Wing A, Suite 1038, Nairobi. WhatsApp +254 739 238 917. Cash can leave the shop the same day or travel. The renewed weekly plan stays in those five counties.
