Podklyuchenie SD-karty k smartfonu Samsung — prostaya na pervyy vzglyad protsedura, kotoraya mozhet prevratitsya v golovnuyu bol, esli ne uchest nyuansy. Dazhe opytnye polzovateli inogda stalkivayutsya s oshibkami vrode «SD-karta ne podderzhivaetsya» ili «Povrezhdyonnaya karta pamyati», ne govorya o problemakh s perenosom prilozheniy ili vyborom faylovoy sistemy. V etoy state razberyom vse etapy — ot fizicheskoy ustanovki do tonkoy nastroyki, a takzhe raskroem sekrety, kotorye proizvoditel ne vsegda upominaet v ofitsialnykh instruktsiyakh.

Osobennost ustroystv Samsung (v otlichie ot mnogikh drugikh brendov) — podderzhka dvukh rezhimov raboty SD-karty: kak portativnogo nakopitelya (dlya foto, muzyki, dokumentov) i kak vnutrenney pamyati (dlya ustanovki prilozheniy). However, not all models support the second option, and some require mandatory formatting before first use. My podrobno obyasnim, kakie modeli Samsung pozvolyayut rasshiryat vnutrennyuyu pamyat at the expense of an SD card, and which ones - only store media files on it, chtoby vy ne tratili vremya na bespoleznye manipulyatsii.

1. Kakie SD-karty podkhodyat dlya Samsung: trebovaniya i ogranicheniya

Prezhde chem pokupat kartu pamyati, proverte technical limitations vashey modeli Samsung. For example, flagship series Galaxy S22/S23 and Note 20 support cards up to 1 TB, while budget ones Galaxy A13/A23 can only work with capacity up to 512 GB. Older models (before 2018) are often limited by 256 GB.

Key parameters when choosing:

  • 🔹 Speed ​​class: to record 4K video you need UHS-I U3 or V30+. For ordinary tasks, it's enough Class 10.
  • 🔹 File system: cards up to 32 GB go to FAT32, above - to exFAT. Some Samsung require reformatting to NTFS to work with large files.
  • 🔹 Brand: avoid no-name cards - they often fake speed characteristics. Optimal SanDisk Extreme, Samsung EVO, Kingston Canvas.

⚠️ Attention: If your Samsung was released before 2017 (for example, Galaxy S7 or Note 5), it may not support cards larger than 200 GB without manual formatting via exFAT via PC. Check the model specifications on the official website.

2. Physical installation of the SD card: where is the slot and how to insert

The location of the slot for SD card depends on the model Samsung:

  • 📱 Flagships (S/Note/Z series): the slot is usually combined with the SIM card tray (hybrid slot). You'll have to choose either a second SIM or SD.
  • 📱 Budget models (A/J series): often have a separate slot for microSD, which allows you to use two SIM + memory card.
  • 📱 Folding (Flip/Fold): the slot may be located under the case cover (for example, in Galaxy Z Flip4).

Step-by-step installation instructions:

  1. Turn off the phone (required for models with one tray for SIM+SD!).
  2. Insert a paperclip into the hole of the tray - it will slide out.
  3. Place the SD card contacts down (for hybrid trays: if you use two SIMs, the SD card will not fit.
  4. Gently push the tray back until it clicks.

☑️ Preparing to install an SD card

Done: 0 / 4

⚠️ Attention: On models Galaxy S20 Ultra i Note 20 Ultra when installing the SD card carelessly the contacts of the slot can be damaged. If the card is not detected after three insertion attempts, contact the service center - bending the contacts yourself often leads to damage.

3. First connection: formatting and selecting the mode of use

After installing the SD card Samsung will offer to select its operating mode. It is important not to make a mistake here:

  • 📁 Portable storage: the card will be used as a flash drive - for photos, music, documents. You can easily remove it and connect it to other devices.
  • 📱 Internal memory: the card will become part of the system (section /sdcard). You can transfer applications to it, but removing the card without formatting will become impossible.

If you selected internal memory, the phone will offer:

  1. Format the card (all data will be deleted!).
  2. Transfer some data from the internal storage to it (optional).
Mode Advantages Disadvantages Supported models
Portable storage Compatible with other devices, easy removal Cannot install apps All Samsung models
Internal memory Memory expansion for applications, cache, updates Cannot be removed without losing data, slower than the internal memory Models with Android 6.0+ (except some budget ones)

⚠️ Attention: On models Galaxy A03/A13 and similar ones, the “internal memory” function may not be available even if there is an SD slot. Check this in the menu Settings → Device care → Memory.

Important nuances:

  • 🔧 After formatting, the card will be encrypted linked to the device. Removing it without formatting will make it unreadable on other gadgets.
  • 🔧 Speed of applications from the SD card lowerthan from the built-in memory (especially on cards Class 10). For games and heavy applications.
  • 🔧 Some system applications (for example, Samsung Pay or Knox) cannot be transferred to SD.

⚠️ Attention: On models with One UI 5.0+ (Android 13), transferring applications to SD may be limited. For example, Galaxy S23 this feature is disabled by default to improve security.

What to do if the "Format as internal memory" button is grayed out?

This means that your Samsung model does not support the Adoptable Storage feature. Try to bypass the restriction using the ADB command: 

adb shell sm set-force-adoptable true

But keep in mind that this may lead to unstable system operation.

5. Transferring data and applications to an SD card

  • 📱 Applications:
    1. Open Settings → Applications.
    2. Select application → Storage → Edit → SD card.

    • 🚫 Application updates may require temporary transfer back to internal memory.

      • ⚠️ Attention: On models Galaxy with One UI 4.0 and later transfer of applications to SD may be blocked for applications using Android App Bundle (format .aabThis applies to most games from Google Play.

      💡

      Moving applications to an SD card makes sense only for light utilities (messengers, e-readers). For games and heavy apps, it is better to use internal memory or cloud services.
