Yes, at medium settings! The Dimensity 6300 handles BGMI and Call of Duty Mobile at 30-40 FPS on medium settings. Perfect for casual gaming. Heavy games like Genshin Impact run at 20-30 FPS on low settings. Plus, 7000mAh enables 8-10 hour gaming marathons!

❓ Does it support expandable storage?

Yes, via microSD card! This is a rare feature in 2025 – most phones dropped microSD slots. You can expand storage beyond 128GB/256GB internal storage. Perfect for storing offline movies, music, and documents!

❓ Is the camera good enough for social media?

Yes, for social media! The 50MP main camera captures good daylight photos perfect for Instagram, Facebook, and WhatsApp. Night mode helps in low light. While not flagship-level, it’s excellent for the ₹22,999 price point!

❓ Can I use it for underwater photography?

Yes, with IP68 rating! The phone is rated for 1.5m underwater for 30 minutes. It includes dedicated underwater shooting mode for pool and beach photography. Perfect for vacation and adventure shots!

❓ Does it come with charger and case in the box?

Yes, both included! Unlike many competitors, OPPO includes the 80W SUPERVOOC charger AND a protective case in the box. You also get USB-C cable, SIM ejector tool, and quick guide. Complete package!

❓ Is ColorOS 15 good or bloated?

ColorOS 15 is based on Android 15 and brings many useful features, but it does have some pre-installed apps (bloatware) that can be uninstalled. The UI is colorful and feature-rich, though not as clean as stock Android. Overall, it’s improved significantly!

❓ Does it support 5G in India?

Yes, fully! The phone supports all major 5G bands in India including n1/n3/n5/n8/n28B/n38/n40/n41/n77/n78. It works with Jio, Airtel, Vi, and BSNL 5G networks. VoLTE calling also supported!

❓ Why is there no NFC?

To keep costs down at ₹22,999, OPPO removed NFC. This means no contactless payments via Google Pay tap-to-pay (though UPI QR codes still work). If NFC is essential, consider Nothing Phone (2a) or Samsung Galaxy M35 at higher prices.

❓ How many years of software updates will it get?

OPPO typically provides 2 years of Android updates and 3 years of security patches for F-series phones. The F31 launches with ColorOS 15 (Android 15), so expect updates through Android 17. Not as long as Samsung’s 4-year support, but adequate!

❓ Is the 120Hz display good for the price?

Yes, excellent! The 120Hz AMOLED display with 1400 nits peak brightness is rare in budget segment. Smooth scrolling, vibrant colors, and excellent outdoor visibility. Better than LCD displays on competitors at this price!

❓ Is OPPO F31 5G worth ₹22,999?

Yes, if battery is priority! The 7000mAh battery + 80W charging + IP69 protection + 120Hz AMOLED + microSD slot deliver ₹30,000+ phone features at ₹22,999. Best value for heavy users and travelers. If gaming is priority, consider Realme Narzo 70 Pro or Poco X7!
