The Galaxy S8 (2017) predates MagSafe-style magnetic phone rings, so purely magnetic mounts need a thin metal plate added inside your case (most magnetic mounts include one) rather than attaching directly. Because of that, this list leads with clamp-style mounts that grip the phone directly and don’t need any add-on hardware, with magnetic options after for anyone willing to add a metal plate.

The picks, in detail
iOttie Easy One Touch 6
The latest generation of the best-known clamp-style car mount, opening and closing around the S8 with one hand and no add-on hardware needed.
- One-touch spring-loaded clamp
- Dashboard and windshield suction-cup base
- Fits phones with or without most cases
- No magnet plate or case modification needed — clamps directly onto the S8
- One of the most widely reviewed and trusted mounts on the market
- Suction-cup base needs a smooth, clean surface to hold long-term
Lamicall Car Vent Phone Mount
A budget clamp mount that grips the air vent fins rather than needing a suction cup, a common low-cost pick for exactly this kind of clamp-style mounting.
- Air vent clip base
- Spring-loaded side clamps
- Thick-case friendly
- One of the cheapest reliable clamp mounts available
- Vent-clip base skips any suction-cup adhesion concerns entirely
- Air vent mounting isn’t ideal if you need that vent for actual airflow/defrost
Qifutan Car Phone Holder Mount
Another budget clamp mount, available in windshield/dashboard suction and vent-clip versions, frequently discounted well under its list price.
- Available in windshield/dashboard and air-vent versions
- Metal spring clip for a secure hold
- Hands-free universal fit
- Frequently on sale for around $10
- Choice of mounting style (vent vs. suction) depending on your dash layout
- Build quality is basic compared to iOttie at this price point
Spigen OneTap MagFit Car Mount
A magnetic vent mount from a well-known phone-accessory brand — works with the S8 if you add the included thin metal plate inside your case, since the S8 has no built-in magnet ring.
- Magnetic mount with an included adhesive metal plate for non-magnetic phones
- Air vent clip base
- Compact, low-profile design
- One of the lowest-priced magnetic mounts available
- Very quick to attach/detach the phone once the plate is installed
- Requires sticking a metal plate inside your case first — not a true out-of-box fit for the S8
VANMASS Magnetic Car Phone Holder
A stronger-holding magnetic mount aimed at buyers who want a firm grip on rougher roads — same metal-plate requirement applies for an S8 without a built-in magnet.
- Strong magnet array plus suction cup base
- Aluminum alloy construction
- Dashboard/windshield mounting
- Noticeably stronger hold than budget magnetic mounts, useful on rough roads
- Requires the included metal plate to work with the S8’s non-magnetic body
- Pricier than the clamp-style options on this list
ESR CryoBoost Car Mount
A magnetic mount built primarily around wireless charging for newer phones — worth listing for S8 owners who want the same mount ready for a future phone upgrade, but the S8 itself won’t get wireless charging from it.
- Magnetic mount with active-cooling wireless charging (for compatible newer phones)
- Vent or dash mounting
- Metal-plate compatible for non-magnetic phones like the S8
- A mount you can keep using through a future phone upgrade to a MagSafe/Qi2-compatible device
- The S8 gets none of the wireless-charging benefit this mount is actually built around — you’re paying for a feature you can’t use yet
Belkin BoostCharge Magnetic Wireless Charging Car Vent Mount
A premium-brand magnetic vent mount, listed here with the same S8 caveat as the ESR above — buy it for the mounting quality, not for charging.
- Magnetic mount with wireless charging for compatible phones
- Air vent clip base
- Belkin build quality and warranty support
- Strong, name-brand build quality for the mounting mechanism itself
- Most expensive mount on this list, and again, the wireless-charging feature doesn’t work with the S8
Beam Electronics Cell Phone Car Air Vent Mount Holder
A budget clamp mount that grips the phone directly via air vent fins, no plate or magnet needed — one of the cheapest reliable clamp options confirmed for sale.
- Air vent clip base
- Spring-loaded side clamps
- Universal fit for phones with or without cases
- Confirmed real listing at one of the lowest prices on this list
- No hardware modification needed — clamps directly onto the S8
- Vent mounting means giving up that vent for airflow while the phone is mounted
Scosche MagicMount Magnetic Phone/GPS Vent Mount (2-Pack)
A well-known magnetic-mount brand sold as a 2-pack, useful if you want a matching mount in two vehicles — same metal-plate requirement as the other magnetic options for an S8.
- Magnetic vent mount
- Sold as a 2-pack
- Compact, low-profile design
- 2-pack pricing works out cheaper per mount than most single magnetic mounts here
- Same metal-plate requirement for the S8 as the other magnetic mounts on this list
Bestrix Premium Magnetic Phone Mount
A magnetic mount combining strong magnets with a suction base, explicitly listed by the manufacturer as compatible with older Galaxy S-series phones including the S8/S9 generation.
- Magnetic hold plus suction cup base
- Explicitly lists Galaxy S8/S9 compatibility (via included metal plate) on the product listing
- Fits phones up to 6.7 inches
- One of the few listings that explicitly names S8-era Galaxy compatibility rather than just ‘universal’
- Still requires the included metal plate inside your case, same as the other magnetic mounts here
Buying tips
- The Galaxy S8 was released in 2017, before Qi2/MagSafe-style magnetic phone rings existed — any ‘magnetic’ mount needs you to stick a thin included metal plate inside your case first, or it won’t hold.
- If you’d rather not modify your case at all, a clamp-style mount (iOttie, Lamicall, Qifutan, Beam Electronics) grips the S8 directly with zero extra hardware.
- Vent-clip mounts are cheaper and skip suction-cup adhesion issues, but consider whether you need that vent for actual heating/cooling airflow before committing to one.
- Wireless-charging car mounts (ESR CryoBoost, Belkin BoostCharge) won’t charge an S8 wirelessly through this kind of mount — buy those only if you’re mounting for a future phone, not for charging the S8 itself.
