The ASUS ZenFone 8 Flip launched in 2021 as ASUS's answer to the notch: instead of a cutout or a pop-up module, the entire triple-camera block rotates to face forward for selfies. Model number ZS672KS paired that mechanism with a Snapdragon 888 and a 5000mAh battery, aimed at buyers who wanted flagship speed and a genuinely edge-to-edge screen without giving up a headphone jack. It still holds value because the hardware was capable at launch and the flip camera remains a rare design choice that collectors and repair shops look for. Pick your storage tier and condition above for a live cash offer, or see how the process works before you commit. If you have more than one device to move, our page to sell your smartphone covers the rest of your Android and iOS lineup.

Confirm you have the ZenFone 8 Flip

Go to Settings → About phone. The model line should read ZS672KS, and the same screen shows your Android version and total storage. If the model field is blank or unreadable, dial *#06# to pull the IMEI and cross-check it against the box label if you still have it.

ZS672KS (ZenFone 8 Flip)

  • Only model number sold for this device
  • 128GB and 256GB storage variants share this model number
  • Global and select carrier-unlocked units use the same designation

Prefer a visual check? Look for the camera block on the back that spans the full width of the phone and physically rotates when you open the camera app to selfie mode. There is no separate front-facing camera cutout or notch anywhere on the display. The frame is metal with glass front and back, and the phone is noticeably taller and heavier than most 2021 flagships because of the flip motor.

Core hardware

Processor

  • Qualcomm Snapdragon 888
  • Same chip across both storage tiers

Memory (RAM)

  • 8GB LPDDR5 paired with the 128GB tier
  • 16GB LPDDR5 paired with the 256GB tier
  • Soldered, not user-upgradable

Storage

  • 128GB or 256GB UFS 3.1
  • No microSD expansion
  • The 256GB/16GB configuration typically holds the most trade-in value

Cameras (flip module)

  • 64MP main sensor (Sony IMX686)
  • 12MP ultra-wide with autofocus
  • 8MP telephoto, 3x optical zoom
  • Same module serves as both rear and selfie camera via rotation

Display & audio

Display

6.67-inch Samsung AMOLED, FHD+ resolution (2400 x 1080), with a 90Hz refresh rate and HDR10+ support. Because the camera flips rather than cutting into the panel, the screen has no notch, hole-punch, or bezel-mounted sensor.

Audio

Dual front-facing stereo speakers tuned by Dirac, plus a 3.5mm headphone jack, which ASUS kept on the ZenFone line even as most flagships dropped it.

Security

Fingerprint reader built into the side-mounted power button. There is no under-display sensor and no dedicated face-unlock hardware.

Ports & connectivity

The port layout is simple: one USB-C for charging and data, and a headphone jack the flip design didn't sacrifice.

Wired
  • USB-C
  • 3.5mm headphone jack
  • Dual nano-SIM tray, no microSD
Wireless
  • 5G (sub-6GHz)
  • Wi-Fi 6
  • Bluetooth 5.2
  • NFC

Battery, build & more

Battery

5000mAh with 30W wired fast charging. There is no wireless charging, a trade-off of building the moving camera block into the chassis.

Dimensions & weight

Larger and heavier than a typical 2021 flagship, a direct result of housing the rotating camera assembly inside the frame.

Build

Aluminum frame with Gorilla Glass front and back. ASUS did not publish an official IP water or dust rating for this model, which matters if the phone has seen regular outdoor or bathroom use.

Known issues

The flip mechanism is a mechanical moving part. Confirm it still rotates smoothly and fully in both directions before you rely on the quoted condition grade, since motor wear is the main age-related failure point on this model.

Frequently asked questions

01 How do I find the model number and exact configuration?
Go to Settings → About phone. The model line reads ZS672KS regardless of storage size, so check the storage figure on the same screen, or under Settings → Storage, to know whether you have the 128GB or 256GB unit. The IMEI, reachable by dialing *#06#, is useful if you need to confirm the device against a receipt or box.
02 How do I tell it apart from the standard ASUS ZenFone 8?
Check the back and the display size. The regular ZenFone 8 has a fixed front camera in a small punch-hole and a 5.9-inch screen, while the ZenFone 8 Flip has no front-facing cutout at all and a larger 6.67-inch panel, because the same triple-camera block rotates to handle selfies. If the camera module physically moves, you have the Flip.
03 Can I sell it with damage, a weak battery, or if it won't turn on?
Yes. A cracked screen, a battery that no longer holds a charge, a stuck flip mechanism, or a phone that won't power on can still be sold; the condition picker above adjusts the offer to match. What can't be worked around is an active lock: any Google account (or Samsung/other account) tied to the phone under Find My Device or FRP must be removed before you ship it, since a locked device usually can't be resold or refurbished.
04 What raises the trade-in value the most?
A smoothly working flip mechanism matters more on this phone than on most, since it's the one moving part and the first thing a buyer tests. Beyond that, higher storage (256GB/16GB), a screen free of cracks or burn-in, an unlocked carrier status, and having the original box and charger all push the offer up. Removing your Google account before you send it in also avoids delays.
05 How do I erase it and get paid?
Back up anything you want to keep, then go to Settings → System → Reset options → Erase all data (factory reset). Before or during that process, remove your Google account under Settings → Accounts, and confirm the screen lock and any FRP protection are cleared so the device isn't tied to you anymore. Once it's wiped, ship it to us using the free, insured label we provide. We test it against the condition you selected and pay by PayPal, Venmo, Zelle, CashApp, or check.
