For many regional SKUs the vendor pushed an OTA package to move the build to 9.0 (Pie); users expecting releases past 9.0 should treat them as unlikely from official channels.
How to confirm your exact build: open Settings → About phone → Software information and check OS version, Build number and Security patch level. If the OS line shows a numeric value starting with 8.1, the box software is Oreo-era; 9.0 indicates the Pie-era update. Record the build number before attempting any manual modifications.
Safe update recommendations: install only vendor-signed OTAs via Settings → System update; back up user data first (full account sync + local backup). If no official updates are available for your SKU and you require a newer major release, consider reputable third-party ROMs listed on enthusiast sites (XDA Developers). Flashing custom firmware requires unlocking the bootloader, installing a custom recovery (TWRP), and following the ROM maintainer’s instructions precisely–proceed only if you accept warranty and security trade-offs.
Quick troubleshooting: if Settings reports the latest official build but apps require a newer platform, check for Google Play Services and app updates, clear app caches, and verify Play Store compatibility settings. For advanced needs (security patches, feature backports), look for vendor-provided security patches or well-maintained unofficial builds specific to your model.
