GoSolo Read / what it means6 takeaways

display

6.8" AMOLED, 1440×3200, 120HzThe 516 ppi density and 120Hz refresh keep text sharp and scrolling smooth, and AMOLED blacks let you read in sunlight without losing contrast against the bright white areas.

performance

Exynos 2100, 2.9 GHz 8-coreHandles demanding games like Genshin Impact at high settings and fast switching between apps, but lags slightly behind the Snapdragon 888 in sustained load.

battery

5000mAh, about 1 day heavy useWith heavy browsing, video, and gaming, you will need a charge by evening; moderate use stretches it into a second day.

charging

Fast Charging, Qi wirelessThe wired fast charging speed is not specified on this sheet, so you will need to confirm the exact watts; wireless charging means topping up at a desk without a cable.

durability

IP68, Gorilla Glass, 8.9mmSurvives submersion in 1.5 m of freshwater for 30 minutes, and the thin 8.9 mm body fits most pockets without adding bulk.

storage

12GB RAM, 128–512GB storageThe 12 GB RAM handles multitasking and heavy apps smoothly; pick 256 GB or higher if you shoot 4K video frequently, since large files eat into space fast.
