What Is Samsung Smart Switch? What Really Transfers to a New Galaxy — and What Silently Doesn’t

Samsung Smart Switch is at its most useful when you understand what it refuses to do. The tool itself is a free data-transfer application Samsung builds into current Galaxy handsets, and it moves contacts, messages, photos, call logs, Wi-Fi passwords and app data from an old phone — Android or iPhone — onto a new Galaxy without sending your life through a cloud round-trip. The problem is the gap between that description and what actually lands on the new handset. Some items do not move at all, and several fail quietly rather than announcing themselves: Google Authenticator codes stay behind, WhatsApp chat history will not follow an iPhone across, and photos can arrive blank if your iPhone was storing them in optimised form. What follows covers the three forms Smart Switch takes, the exact compatibility floors Samsung publishes, which cable or adapter makes a wired transfer work first time, and the migration steps most likely to cost you access to an account you still need.

Quick picks: what you actually need to buy

The transfer software is free. What costs money is the cable or adapter that makes a wired transfer fast and reliable — and the correct one depends entirely on which phone you are moving away from.

The destination handset itself is covered in its own section further down, because the receiving device matters as much as the cable.

What Samsung Smart Switch is (and the three forms it takes)

Smart Switch is a data-transfer application — not a subscription, not cloud storage, and not a paid upgrade tier. Samsung describes it as giving you “the freedom to move your contacts, music, photos, calendar, text messages, device settings and more to your new Galaxy device.” Where an app you used on your old phone has no direct Galaxy equivalent, it also suggests comparable apps from Google Play, which saves you hunting for replacements by name.

It is pre-installed on current Galaxy devices, though not on every Galaxy ever made — grey imports and older models vary, so check before assuming it is already sitting on the handset. On non-Galaxy Android phones it is a free download from Google Play.

There are effectively three versions of the same tool:

• Smart Switch Mobile — the Android app. It ships by default on Galaxy phones and is free to download on other Android handsets running Android 6.0 or higher.
• Smart Switch for PC and Mac — a desktop application that pulls data out of an iTunes backup and pushes it to a connected Galaxy. This is the route for anyone whose iPhone data lives on a computer rather than in iCloud.
• The iPhone side — there is no iOS app at all. An iPhone instead connects to the Galaxy by cable, or the Galaxy pulls directly from iCloud on the iPhone’s behalf.

According to Samsung’s Google Play listing, Smart Switch Mobile has passed 1 billion downloads and holds a 3.8-star average across roughly 533,000 reviews. That pairing is informative: it is plainly the default migration route for a very large number of UK phone owners, and it is clearly not flawless for every single one of them. The app carries a PEGI 3 rating, so nothing inside it is age-restricted, and it requires a set of standard Android permissions to read messages, contacts, storage and Wi-Fi settings during the transfer — permissions it needs precisely because those are the things it is copying.

Does Smart Switch cost anything?

No. Samsung does not charge for Smart Switch, and no feature inside it sits behind a paywall. The only genuine costs are the cable or adapter you may need to buy, and the time the transfer takes. That is worth stating plainly, because a great deal of paid software exists to do a smaller version of the same job.

What Smart Switch transfers: the complete list

According to Samsung’s app listing, the following moves across from an Android phone to a Galaxy:

• Contacts
• Calendar entries — device content only
• Messages — SMS and MMS
• Photos
• Music — DRM-free content only
• Videos — DRM-free content only
• Call logs
• Memos
• Alarms
• Wi-Fi networks and saved passwords
• Wallpapers
• Documents
• App data — Galaxy devices only
• Home screen layouts — Galaxy devices only

Those last two entries carry the important caveat. App data and home screen layouts move only when both devices are Galaxies, and both must meet the Android 6.0 floor described below. Come from a Pixel, a Xiaomi or a OnePlus and you still get your files, messages and media — but your apps arrive as fresh installs with their settings, logins and saved progress gone. If you are switching between Android brands, plan to sign back into anything that matters.

What doesn’t transfer — and why it catches people out

This is the section the tool’s own marketing does not lead with. Owner consensus across Samsung Community forums and Reddit’s r/GalaxyS points to a consistent set of silent failures, where the transfer finishes with no error message and the loss only surfaces days later.

Google Authenticator and other TOTP two-factor seeds. Authenticator codes are generated from secret keys stored inside the app’s own secure container, and those keys are not part of the transferable payload. If your only second factor for a bank, email account or workplace login lives in an authenticator app on the old phone, you must move those seeds manually before you factory reset it. Wipe the old handset first and you can lose account access outright.

WhatsApp chat history from an iPhone. This is blocked by WhatsApp’s own platform restrictions rather than by any fault in Smart Switch, so no cable, adapter or retry will fix it. Android-to-Android moves are a different conversation, but an iPhone-to-Galaxy migration will not carry your chat threads across.

Banking app logins and saved credentials. Banking apps clear their stored credentials when the app is reinstalled on new hardware. Expect to re-activate each one using your card, PIN or the bank’s own in-app process.

Offline downloads from Netflix, Spotify and BBC iPlayer. These files are DRM-locked to the device that downloaded them, so they cannot be copied. Nothing is lost except the time it takes to re-download on the new phone.

Secure Folder contents. Everything inside a Secure Folder is excluded from the transfer entirely. The container is encrypted and bound to the old handset, so move anything you need out of it manually before you wipe.

eSIM profiles. Smart Switch does not touch them. An eSIM has to be re-provisioned through your carrier, which for many UK networks means an app-based or online process rather than a shop visit.

RCS message threads. SMS and MMS transfer; RCS history does not. RCS is the richer, internet-based messaging layer many Android phones now default to, so recent conversations may simply be missing even though older texts arrive intact.

iCloud Photos in “Optimise iPhone Storage” mode. If your iPhone was set to keep only low-resolution placeholders on the device and hold the originals in iCloud, photos can arrive blank or at reduced resolution. The fix is to enable full-resolution download on the iPhone before you start.

Finally, one reassurance worth having: the old phone keeps all its data after the transfer. Nothing is deleted until you manually factory reset it, which is exactly why the manual steps above should be completed first.

Compatibility: the exact requirements Samsung states

Samsung publishes its compatibility figures on its Smart Switch support pages at samsung.com/uk/support (accessed 2026), and they are worth reading literally rather than approximately.

• Sending device minimum: Android 6.0 (Marshmallow). As a rough shorthand, that means phones from around 2016 onwards.
• App data and home screen layouts: Galaxy-to-Galaxy only, with both devices meeting that same Android 6.0 floor.
• iPhone, wired: iOS 12.0 or above, with a Lightning cable only. Every iPhone that can run iOS 12 uses Lightning, so no 30-pin connection is involved anywhere in this process.
• iPhone, iCloud import: iOS 4.2.1 or above.
• iTunes music: purchases made after 2009 under iTunes Plus are DRM-free and do transfer. Apple Music downloads, iTunes Match content and iTunes movie or TV purchases are DRM-locked and do not.

How to choose the right cable or adapter

Two decisions settle almost everything.

First: wired or wireless. A cable transfer is markedly faster and steadier than the Wi-Fi Direct route that connects the two phones directly to each other. For anything beyond a few hundred photos, the cable is the better choice.

Second: which cable your old phone needs. The split falls on the iPhone 15, which moved Apple’s handsets to USB-C:

• iPhone 15 and later need a USB-C to USB-C cable.
• iPhone 14 and earlier need a USB-C to Lightning cable, or alternatively a Lightning-to-USB-A cable paired with an OTG adapter to reach the Galaxy’s port.
• Android to Android uses USB-C to USB-C in most cases.

One hardware note that affects card-based content: no current flagship Galaxy, from the S25 series onward, has a microSD slot. If your photos or music sit on a card in your old phone, you cannot simply move the card into the new handset — it has to come across through the transfer itself.

The products

Samsung Galaxy S25 — the destination handset

Best for: anyone who wants the receiving end of the transfer to have zero compatibility caveats.

What you get: Smart Switch is pre-installed, so there is nothing to download on the receiving side, and the handset sits at or above every compatibility floor Samsung states. It accepts a wired transfer from an Android 6.0-or-later phone or an iPhone on iOS 12.0 or above, and it can pull directly from iCloud on an older iPhone’s behalf.

Standout strength: because the destination is a current Galaxy and the old phone is a Galaxy too, this is the configuration in which app data and home screen layouts transfer as well — the two categories that stay behind in every cross-brand move. Your apps arrive already signed in and laid out as before.

Honest caveat: no microSD slot from the S25 series onward. Anything stored on a card in your previous phone has to travel through the transfer rather than being physically slotted in.

Verdict: the simplest possible migration target — the tool is already there and every compatibility condition is met without argument.

Where to buy: UK mobile networks and high-street electronics retailers typically stock the S25 range, with pricing varying by model, storage tier and whether you buy on contract or SIM-free.

Anker USB-C to USB-C cable

Best for: Android-to-Android wired transfers, and any iPhone 15 or later moving to a Galaxy.

What you get: a single USB-C to USB-C cable, nothing else in the box. It carries the data connection between old phone and new Galaxy on the wired route.

Standout strength: wired transfers are markedly faster and steadier than Wi-Fi Direct, so a cable in the around £10–£15 band buys you a materially better migration than the wireless option.

Honest caveat: it only fits if both ends are USB-C. Buy this for an iPhone 14 or earlier and it will not connect, because those handsets use Lightning.

Verdict: the default purchase for most Android-to-Android switches, and the only correct cable type for iPhone 15 and later.

Where to buy: Amazon UK, Currys and Argos.

Ugreen USB-C cable

Best for: the same USB-C-to-USB-C route, for buyers who want an alternative to Anker at the same level.

What you get: a single USB-C cable. Like the Anker option, it is a one-piece product with no adapters or extras included.

Standout strength: the spine of this purchase is simply the price band — branded USB-C cables from either Anker or Ugreen typically land around £10–£15, so there is no need to pay more for a data transfer that is not demanding anything exotic from the cable.

Honest caveat: the same port-matching rule applies. If your old phone is an iPhone 14 or earlier, a USB-C to USB-C cable is the wrong item entirely.

Verdict: a sensible equivalent to the Anker cable, and a useful second brand to compare when stock or length options differ.

Where to buy: Amazon UK, Currys and Argos.

Anker USB-C to Lightning cable

Best for: wired transfers from an iPhone 14 or earlier to a Galaxy.

What you get: a single USB-C to Lightning cable — USB-C at the Galaxy end, Lightning at the iPhone end. That is the exact pairing Samsung specifies for iOS 12.0-and-above iPhones on the wired route.

Standout strength: it keeps the whole transfer on-device, with no iCloud round-trip and no dependence on your iCloud storage allowance. For anyone with a large photo library, that avoids the full-resolution-download step that iCloud imports depend on.

Honest caveat: it becomes obsolete the moment you upgrade to an iPhone 15 or later, since those handsets have no Lightning port.

Verdict: the sanctioned cable for iPhone 14-and-earlier owners, and the one to buy if you would rather not involve iCloud at all.

Where to buy: Amazon UK, Currys and Argos.

USB OTG adapter

Best for: anyone who already owns a Lightning-to-USB-A cable and needs to reach the Galaxy’s USB-C port.

What you get: a single small adapter that converts the connection so the cable you already own can plug into the new phone.

Standout strength: OTG adapters run approximately £5–£8, which makes this the cheapest way into a wired transfer if you would otherwise be buying a whole new cable. Samsung lists the Lightning-to-USB-A-plus-OTG combination as a valid route for iPhone 14 and earlier.

Honest caveat: it adds an extra physical joint in the chain, and it is one more small item to lose between migrations.

Verdict: a sensible £5–£8 shortcut for existing cable owners, and a genuine alternative to buying a USB-C to Lightning cable outright.

Where to buy: Amazon UK, Currys and Argos.

UK notes: retailers, disclosure and where the claims come from

Ofcom and Canalys data confirm that Samsung holds the largest single Android share in the UK, which is the honest reason Smart Switch matters more here than many other migration tools — it is the default first experience for a large slice of UK Android buyers, not a niche utility. If you need a compatible cable or adapter, Amazon UK, Currys and Argos are the retailers to check.

Every compatibility figure in this guide is taken from Samsung’s own Smart Switch support pages at samsung.com/uk/support (accessed 2026), and the download and rating figures come from Samsung’s Google Play listing. The failure patterns in the “what doesn’t transfer” section reflect owner consensus from Samsung Community forums and Reddit’s r/GalaxyS rather than any controlled test — they are the recurring complaints, reported consistently enough across many users to plan around.

FAQ

Is Samsung Smart Switch free to use? Yes. Samsung does not charge for the app, and no feature inside it is paywalled. The only real costs are the cable or adapter you may need and the time the transfer takes. It is pre-installed on current Galaxy devices and free to download from Google Play on other Android handsets running Android 6.0 or higher.

Can I transfer from an iPhone to a Samsung Galaxy? Yes, through one of two routes. A wired transfer needs iOS 12.0 or above and a Lightning cable, while an iCloud import works from iOS 4.2.1 or above and pulls the data down on the Galaxy’s behalf. There is no iOS version of the Smart Switch app, so the iPhone never runs the software itself.

Why did my photos arrive blank or at low resolution? Your iPhone was almost certainly set to “Optimise iPhone Storage”, which keeps low-resolution placeholders on the device and stores originals in iCloud. Enable full-resolution download on the iPhone before starting the transfer, and the photos should arrive intact. It is worth checking this before you begin, not after.

Why won’t my WhatsApp messages transfer from my iPhone? WhatsApp blocks chat-history migration across platforms itself — this is a restriction WhatsApp applies, not a defect in Smart Switch. No cable or retry will change it. If the history matters, export the chats from within WhatsApp before you switch.

Can I use Smart Switch with a non-Samsung Android phone? Yes. Download Smart Switch Mobile free from Google Play on any Android 6.0-or-higher handset and it will send your contacts, messages, media, call logs, alarms, Wi-Fi passwords and documents to a Galaxy. The catch is that app data and home screen layouts transfer only between two Galaxy devices, so apps will arrive as clean installs without their logins.

Do I need to wipe my old phone first? No — and you should not. Nothing is deleted from the old phone during the transfer; it keeps all of its data until you manually factory reset it. Completing the steps that Smart Switch cannot handle, such as moving two-factor authentication seeds, has to happen before that factory reset.

Do I need a different cable for an iPhone 15 or later? Yes. The iPhone 15 moved to USB-C, so you need a USB-C to USB-C cable rather than the USB-C to Lightning cable used by iPhone 14 and earlier models. If you are moving an iPhone 15 or newer and buy the wrong cable, the wired route simply will not connect.

The bottom line

Smart Switch is free, pre-installed on current Galaxies, and genuinely good at the bulk of the job: contacts, messages, photos, call logs, Wi-Fi passwords, alarms, wallpapers and documents all travel, and app data and home layouts travel too when both phones are Galaxies. What it will not do is rescue you from the quiet failures — authenticator seeds, Secure Folder contents, eSIM profiles, RCS threads, banking logins, DRM-locked downloads and WhatsApp history from an iPhone. Handle those by hand first, buy the right £10–£15 cable or £5–£8 adapter for your old phone’s port, and run the transfer before the factory reset rather than after.
