TL;DR - The Samsung RF29DB9900 is a 36-inch Bespoke 4-Door Flex with 28.6 cu. ft., a FlexZone drawer, a Beverage Center, AI Vision Inside and a 32-inch AI Family Hub+ screen. Samsung rates it at 700 kWh per year. Samsung US sells it at $3,699 against a $4,999 list price in mid-October 2026, retailers ran from about $3,160 to $4,999 this autumn, and sale prices cluster near $3,400 to $3,800. Samsung's page already flags a newer model, the RF90F29EECR.
Cross-shopping? This is one specific product review. For the full market overview, see the smart fridge buying guide (pillar) and the best smart refrigerators 2025 round-up. Considering the smaller counter-depth Bespoke instead? Read the Samsung Bespoke 4-Door French Door review for the 23 cu. ft. option. Prices on this page are in US dollars; the round-up carries UK prices in pounds.
Updated October 2026: The old page described a "3-Door French Door" sibling, a 7-inch versus 8.2-inch screen comparison, a $2,800-3,500 price band and FlexZone temperatures in degrees. Samsung's spec sheet and retail listings don't support those. The page was rewritten around Samsung's RF29DB9900 sheet. The star rating and every hands-on claim were removed, because nobody on this site tested the fridge. A second pass on 14 October 2026 re-checked the prices against Samsung US and four retailers, raised the floor from an unsourced $2,660 to the $3,160 actually found, and dropped a "Full HD, capacitive" screen description no source stated.
Start with what you're buying. Samsung's sheet calls it the Bespoke 4-Door Flex Refrigerator 29 cu. ft. with AI Family Hub+ and AI Vision Inside. The usable total is 28.6 cu. ft.: 17 in the fresh-food section, 5.8 in the freezer and 5.8 in the FlexZone drawer. Retail listings give a bit different split, so treat the total as the number to trust.

What Does the Layout Get You?
The 4-Door Flex puts two French doors on top and two drawers below. Samsung's sheet lists a freezer compartment and a FlexZone drawer in the lower section, with a dual ice maker in the freezer and two ice buckets.
The advantage is plain. One drawer stays a freezer, and the other changes job: Fruit/Veggies for the week, Meat/Fish when you've shopped in bulk, Beverage when you host. Whether you'd actually flip it that often is the honest question. In my view, a household that never leaves the factory setting has paid for a feature it doesn't use.
What Do FlexZone and the Beverage Center Do?
Samsung's sheet lists five FlexZone settings, and no temperatures in degrees. Earlier versions of this page printed specific degrees for each mode, and I couldn't source them, so check the manual for the numbers before you rely on one for food safety.
The sheet also lists a Beverage Center with a choice of an internal dispenser or a built-in AutoFill water pitcher, which is a small but practical extra for anyone who fills a jug every day.
What Do the AI Vision and Auto Open Door Add?
Samsung says AI Vision Inside automatically recognizes what's in your fridge, and that you can see a list of the contents in the SmartThings app or on the Family Hub+ screen. It calls Family Hub+ the industry's largest fridge screen, and Samsung's own product title puts it at 32 inches. The sheet also lists Auto Open Door.
Those are big claims, and I couldn't find an independent test of how accurate the recognition is. A camera only sees the front row of a shelf, so assume it won't catch a jar at the back. If you already use a tablet or phone for lists, the screen is the part of the price I'd question first.
What Does AI Energy Mode Do?
Samsung markets AI Energy Mode across its Bespoke AI refrigerators. On its UK AI energy page and other regional pages it describes adjusting compressor speed and defrost cycles to your usage and room temperature, with savings of up to 10 percent in the headline and up to 15 percent in the body text, the larger figure measured with the AI mode switched on against the factory setting. Those are Samsung's own claims, made under its test conditions, and they vary by region and model.
The US spec sheet for this model doesn't list the feature at all, so check with the seller. What the sheet does give you is the number to use: 700 kWh a year.
What Are the Bespoke Panels Like?
Samsung's sheet lists eleven color options across glass and steel for this model, from White Glass and Charcoal Glass to Navy Steel, Morning Blue Glass, Matte Black Steel and Emerald Green Steel, and says the panels can be changed. The model number changes with the finish, so compare the suffix, not just the price.
The finish matters most if you own other Bespoke appliances and want a match. The mechanics under the panel don't change.
What Does the Warranty Tell You?
Samsung's sheet lists one year of parts and labor on the refrigerator, five years of parts and labor on the sealed refrigeration system only, and ten years of parts plus five years of labor on the Digital Inverter compressor. Read that as a limit, not a promise: the screen, the cameras and the water system sit under the one-year cover.
That's the real cost of a smart fridge. The cooling hardware has long cover. The electronics you pay extra for don't.
RF29DB9900 or the 23 cu. ft. Bespoke?
Samsung's counter-depth sibling is the RF23DB9900QD, with the same AI Family Hub+ and AI Vision Inside. Retail listings give it 22.8 cu. ft. (ENERGY STAR says 22.5), 631 kWh per year, and about 35 7/8 x 73 x 28 3/4 inches. The RF29DB9900 holds more and uses more electricity, 700 kWh against 631, and it is the standard-depth choice, so it will stick out past a counter.
If you have the kitchen width and floor depth, and you cook in bulk or host often, the 29 cu. ft. model's extra room has an obvious use. If you don't push a 23 cu. ft. fridge to capacity, the smaller one costs less and fits flush. Our 4-Door French Door review, linked at the top of this page, covers the older RF23BB8900, which is a different fridge again.
Summary
The Samsung RF29DB9900 is a large, well-equipped smart fridge with a flexible drawer, a 32-inch screen and a long compressor warranty. Samsung's own sheet backs the 28.6 cu. ft., 700 kWh per year and five FlexZone settings. The AI claims are Samsung's alone. Retail prices swing by about $1,800 between sellers, and Samsung has already flagged a successor, so shop around and ask about clearance before you commit. If you can't name what you'd keep in that flex drawer, you're paying for a second vegetable bin, and the smaller fridge is the better buy.
