As of July 2026, most new 5G smartphones use newer Snapdragon modems (X65, X70, X75), but a handful of models still rely on the older Snapdragon X55 modem for voice calling and connectivity. These are typically mid‑range or slightly older flagship devices that remain available in the market.
📱 Smartphones with Snapdragon X55 (Still Available in 2026)
⚙️ Why X55 Still Matters
Multi‑mode support: Works across 2G, 3G, 4G LTE, and 5G (sub‑6 GHz + mmWave).
Voice over 5G (VoNR): Enables high‑quality voice calling on 5G networks.
Peak speeds: Up to 7 Gbps download and 3 Gbps upload.
⚠️ Trade‑Offs in 2026
Battery efficiency: Newer modems (X65/X70/X75) are more power‑efficient.
Network compatibility: Carriers in Malaysia (CelcomDigi, Maxis, U Mobile) are shifting toward X65+ devices for better spectrum aggregation.
Availability: X55 phones are mostly found in refurbished markets or discounted stock, not in brand‑new flagship lines.
🧠 Copilot’s Take
If your goal is voice calling on 5G, X55 devices still deliver reliable performance. However, for future‑proofing (especially with Malaysia’s rollout of 5G SA networks), I recommend considering at least Snapdragon X65‑based models.
Would you like me to list Malaysia‑available refurbished retailers that still stock these X55 smartphones, so you can compare local prices and warranty options?
Hi Copilot , does the SAMSUNG Galaxy S20 Ultra 5G smartphone come with SAMSUNG DeX so that i can connect the SAMSUNG Galaxy S20 Ultra 5G to my 40 inches HDMI-enabled External Monitor ? THANKS for the answer Copilot.
Yes — the Samsung Galaxy S20 Ultra 5G fully supports Samsung DeX, meaning you can connect it to your HDMI‑enabled 40‑inch external monitor and use it in a desktop‑like mode. You can do this either with a USB‑C to HDMI cable/adapter or wirelessly if your monitor supports Miracast/Smart Monitor features.
🔌 Connection Options for Samsung DeX on Galaxy S20 Ultra 5G
HDMI Cable/Adapter
Plug a USB‑C to HDMI adapter into your Galaxy S20 Ultra.
Connect the HDMI cable to your external monitor.
The phone will automatically switch to DeX mode, showing a PC‑like interface.
Wireless DeX
Works with Samsung Smart Monitors or any HDMI display that supports Miracast.
Swipe down → Quick Settings → Tap DeX → Select your monitor → Start.
Your phone can act as a touchpad/mouse for navigation.
🖥️ Compatibility with Your 40‑Inch HDMI Monitor
Since your monitor is HDMI‑enabled, the USB‑C to HDMI cable method is the most reliable.
Wireless DeX is convenient but requires Miracast support — check if your monitor has this feature.
Resolution support: FHD (1920×1080) and WQHD (2560×1440) are supported in DeX mode.
⚠️ Things to Keep in Mind
Performance: DeX runs smoothly on the S20 Ultra thanks to its Snapdragon 865 + X55 modem combo.
Peripherals: For best experience, connect a Bluetooth keyboard and mouse.
Power: Use a Samsung fast charger while running DeX to avoid battery drain.
Cable quality: Samsung recommends official or high‑quality HDMI adapters for stable performance.
🧠 Copilot’s Take
Your Galaxy S20 Ultra 5G is fully capable of turning into a mini desktop when paired with your 40‑inch HDMI monitor. If you want maximum stability and resolution, go with the USB‑C to HDMI cable setup. Wireless DeX is great for flexibility, but HDMI gives you the most consistent experience.
Would you like me to walk you through a step‑by‑step setup guide for connecting your Galaxy S20 Ultra to your external monitor using Samsung DeX?
