This handset shipped in September 2019 with OS 9 (Pie) paired with One UI 1. Here is more information on 1xbet promo code for registration stop by our own webpage. 1. It received two official major upgrades: a move to OS 10 (One UI 2) and then to OS 11 (One UI 3). There is no official upgrade beyond the third major release for this model from the device maker.

Security maintenance followed the major releases: monthly patch cadence during the first year after each major update, then less frequent deliveries and eventual end of vendor updates around mid-2022 for many units of this lineup. Expect up-to-date security fixes only while the device remains on an officially supported build.

How to confirm and update: open Settings → About phone → Software information to see the current OS build; then Settings → Software update → Download and install to fetch official over‑the‑air updates. Back up data to your Google account and a local copy before applying a major upgrade. Ensure at least 50% battery or connect to a charger and use a stable Wi‑Fi network for the download.

If you require features from later releases (OS 12+), options are: 1) migrate to a newer handset that ships with those releases; 2) install a third‑party custom firmware (example: LineageOS) – this provides newer builds but requires unlocking the bootloader, voids any remaining warranty, and increases risk of instability. For most users who prioritize reliability and security, remaining on the official OS 11 (One UI 3) build with monthly or quarterly security patches is the recommended course.

Identify the Android version installed on your A30s

Open Settings → About phone → Software information and read the "OS release" and "Build number" entries to get the exact installed release immediately.

   Follow this path: Settings → About phone → Software information.

   
   
   • 
     
   • OS release – core platform number (examples: 9 (Pie), 10, 11, 12, 13).
   • 
     
   • UI layer – manufacturer's interface name and its release (for example One UI 3.1).
   • 
     
   • Security patch level – date in YYYY‑MM‑DD format showing the latest security update applied.
   • 
     
   • Build number – full build identifier; use it when searching firmware lists or support pages.
   • 
     
   • Kernel version – kernel release and compile date (useful for low‑level troubleshooting).
   • 
     
   • Baseband version – modem firmware identifier (relevant for connectivity fixes).

   Use a quick mapping to interpret API/SDK numbers:

   
   
   • 
     
   • API 28 → 9 (Pie)
   • 
     
   • API 29 → 10
   • 
     
   • API 30 → 11
   • 
     
   • API 31 → 12
   • 
     
   • API 32 → 12L
   • 
     
   • API 33 → 13

   Advanced check via ADB (for users with a PC):

   
   
   • 
     
   • Enable Developer options: tap Build number seven times in Software information, then enable USB debugging.
   • 
     
   • Connect via USB and run these commands:
     
     • 
       
     • adb shell getprop ro.build.version.release – returns the release number (e.g., "11").
     • 
       
     • adb shell getprop ro.build.version.sdk – returns the API integer (e.g., "30").
     • 
       
     • adb shell getprop ro.build.version.security_patch – returns the security patch date.
     • 
       
     • adb shell getprop ro.build.fingerprint – returns the full build fingerprint for exact matching.
     •

Open Settings → About phone to read Android version

Open Settings → About phone → Software information and read the OS release and build fields immediately.

Note the exact entries labeled OS release (release name or number), Build number, Kernel version, and Security patch level. Also record Baseband or Modem version and the device IMEI shown under Status.

Capture a screenshot (press Power + Volume Down simultaneously), or copy the Build number into a note. Retrieve IMEI with the dial code *#06# or via About phone → Status.

Use the captured Build number and security patch date to check the manufacturer's support pages or carrier update notes for matching firmware releases. If an update is available, connect to Wi‑Fi, charge above 50%, then go to Settings → Software update and select Download and install.
