Getting a new phone should be exciting. But the moment you think about moving your contacts, photos, chat history, and even your home screen layout all over again, the excitement quickly turns into dread. Samsung clearly understands this pain, which is why Smart Switch has become one of the most firmly established preinstalled apps on Galaxy devices. Its official purpose is simple: help you move everything from your old device to your new Galaxy with as little friction as possible. But while the app has racked up over 511,000 reviews on Google Play, its rating tells a more complicated story. User complaints center mainly on permission requirements and the limits of what it can actually migrate. So is it any good? Let's break it down.
What can it actually move? More than you'd expect — and less than you'd hope.
Smart Switch's core strength is acting as a data ferry for the Samsung ecosystem. The official list of supported content is impressively long: contacts, calendars, messages, photos, music, videos, call logs, memos, alarms, Wi-Fi settings, wallpapers, documents, and even home screen layouts. For Galaxy-to-Galaxy transfers, it can also move app data, which means some of your apps may retain their login states and settings when you upgrade to a new Samsung phone. That saves a lot of repetitive work. But there's a critical limitation: when transferring from a non-Samsung Android device, app data cannot be moved. You'll have to reinstall and log into those apps manually. A highly upvoted negative review on Google Play pointed directly at this: "The most important thing — app data — cannot be migrated."
Switching from iPhone? Wired is king, wireless is a compromise.
For users considering jumping from iPhone to Galaxy, Smart Switch offers three paths: wired transfer, iCloud import, and PC/Mac transfer via iTunes. The most reliable option is wired. All you need is a Lightning-to-USB-C cable (or an appropriate adapter), and you can move contacts, messages, photos, videos, memos, calendars, and even voice memos directly across. But iMessage is the exception: if you don't turn off iMessage beforehand, your SMS migration may run into problems. iCloud import is convenient but has one hard limitation — it cannot migrate music, because Apple Music's DRM protection leaves Smart Switch powerless. As for wireless transfer, while it supports sending contacts, calendars, photos, and videos from iOS, the experience is far less stable than wired. It's fine for lightweight users who only need the essentials.
That "all permissions required" complaint — what's really going on?
In the Google Play review section, one negative review with 13 upvotes reads: "It won't let you use it unless you grant every permission." This is genuinely one of Smart Switch's most frustrating aspects. According to the official description, the permission list is daunting: phone, call logs, contacts, calendar, camera, SMS, storage/files and media, nearby devices, location, and notifications. Samsung's official response is that "backing up and restoring various types of data requires these permissions" — which makes logical sense. If you want to transfer messages, it needs to read messages. If you want to transfer call logs, it needs to read call logs. But the problem is that when a user only wants to transfer photos, they're still forced to grant SMS and call permissions. This "all or nothing" design feels particularly heavy-handed in an era of growing privacy awareness. Even more noteworthy is the data safety declaration on Google Play: data is not encrypted, and cannot be deleted. For an app that handles all of your personal data, that statement is more than a little unsettling.
The process is simple — but that simplicity comes at a cost.
Setting aside the permission controversy, Smart Switch's actual usage flow is smooth. When you first set up a new phone, it appears as part of the setup wizard. If you've already skipped it, you can always access it through "Settings > Accounts and Backup > Smart Switch." Bring the two devices close together, scan a code or connect manually from the old device, select the content categories you want to transfer, and wait for the progress bar to finish. It also supports a "quick setup" mode where the old phone scans a QR code on the new phone's screen, automatically carrying over Wi-Fi passwords and account information, saving you from manual entry. But there are two hard requirements: both devices need at least 500MB of free internal storage, and it's best to keep both devices sufficiently charged during the transfer, or it may be interrupted.
Updates are improving things, but long-standing pain points remain.
Samsung hasn't stopped refining Smart Switch. According to 2026 update information, with the rollout of One UI 9, the iOS migration experience has been upgraded: you no longer need to install the Smart Switch app on your iPhone separately. Simply scanning a QR code on the new Galaxy starts the transfer. The range of migratable content has also expanded, adding support for passwords and passkeys, call history, accessibility settings, and even eSIM information. This is clearly aimed at making the switch from iPhone as painless as possible. But for users migrating from older, non-Samsung Android devices, the core pain points — app data cannot be transferred, and some third-party account data doesn't sync — remain unresolved.
Who is it not for? And when should you skip it entirely?
Smart Switch is not a magic bullet. It can only transfer from non-Galaxy devices to Galaxy devices, not the other way around. If your old phone is a Windows Phone or BlackBerry, what it can move is even more limited — mainly contacts and basic files. Additionally, DRM-protected content (such as iTunes-purchased music and some videos) cannot be transferred at all. More importantly, if your core need is migrating WeChat chat history or game save data, Smart Switch can't help you. That kind of in-app data is usually tied to each service's own ecosystem and requires the app's built-in backup or cloud sync features. For these scenarios, honestly going through the in-app migration process is far more reliable than hoping a system-level tool will handle it.
Final advice: treat it as a safety net, not a perfect solution.
Smart Switch is a classic "official preinstalled tool": it covers about 80% of common migration scenarios, has a low learning curve, and is especially friendly for users upgrading from an old Galaxy to a new one. But its permission strategy feels clunky, and its functional boundaries when migrating from iOS often leave users confused. If you're about to switch phones, here's how to use it: start with Smart Switch for the basics — contacts, photos, videos, and messages — then use each app's own backup feature for chat histories and game saves, and finally log into the apps that require accounts manually. It won't disappoint you, but it won't surprise you either. When it comes to switching phones, that might just be the most practical choice.
