GoSolo Read / what it means7 takeaways

camera

108MP main, 3x and 10x opticalThe 108MP 1/1.33-inch sensor with 0.8µm pixels handles well-lit scenes with fine detail, while dedicated 3x and 10x periscope lenses deliver true zoom without cropping or losing sharpness on distant subjects.

display

120Hz AMOLED, 1500 nits peakThe 6.8-inch 1440×3200 screen at 515 ppi stays readable in direct sunlight thanks to the 1500-nit peak brightness, and the 120Hz refresh keeps scrolling and gaming smooth.

battery

5000 mAh, about 1 day heavy useWith moderate to heavy screen-on use (video, gaming, browsing), expect roughly 12 to 16 hours before needing to charge, though light use can stretch closer to two days.

charging

25W wired, roughly 50 to 70 minutesThe 25W wired charger takes approximately 50 to 70 minutes to reach full from zero, while 15W wireless charging is slower (around 2 to 3 hours) but convenient for overnight top-ups.

performance

Exynos 2100 or Snapdragon 888Either chipset (depending on region) handles demanding games at high frame rates and can run demanding apps like video editing or 3D rendering without stuttering, though the Snapdragon variant is slightly faster in sustained loads.

durability

IP68, Gorilla Glass VictusThe phone survives dust and water submersion up to 1.5 meters for 30 minutes, and Gorilla Glass Victus protects the front and back from drops and scratches better than earlier glass versions.

connectivity

5G, Wi-Fi 6E, UWB, NFCFull 5G support (Sub-6 and mmWave on some models) plus Wi-Fi 6E and UWB chip enable fast downloads, lower latency, and advanced location sharing with compatible devices.
