GoSolo Read / what it means6 takeaways

display

90Hz AMOLED, 750-nit peakScrolling feels noticeably smoother than 60Hz phones, and the high peak brightness keeps the screen readable in bright sunlight despite the relatively modest 409 ppi density.

performance

Snapdragon 768G, Adreno 620This 2021 chipset handles everyday apps and video calls without lag, and runs mid-range mobile games (Genshin Impact medium settings, PUBG) at playable framerates, but not consistently smooth AAA titles.

camera

64MP main, 8MP ultra, 2MP macroThe f/1.7 main sensor captures sharp daylight shots and performs better in low light than smaller apertures, while the 8MP ultrawide covers group photos and landscapes, though the 2MP macro is too low-res to resolve fine detail.

battery

4300mAh, about 1 day moderate useWith mixed browsing, messaging, and occasional video, expect roughly 18 to 20 hours before needing a charge, though heavy gaming or video streaming cuts that to 12 to 14 hours.

charging

65W wired, 35 minutes fullThe 4300mAh battery reaches 100% in the stated 35 minutes, so you can grab a meaningful top-up (50% in about 15-18 minutes) before leaving home.

connectivity

5G, dual SIM, no microSD5G bands 1, 3, 28, 41, 77, 78 cover major networks in most regions, and dual nano-SIM lets you use two carriers simultaneously, but the fixed 128GB or 256GB storage cannot expand via card.
