GoSolo Read / what it means6 takeaways

performance

Snapdragon 888, Adreno 660 GPUThe flagship 2021 chipset handles sustained gaming (like PUBG at high settings) and heavy multitasking without throttling, though it runs warmer than newer rivals.

display

120Hz AMOLED, 1300 nits peakThe 120Hz refresh makes scrolling fluid and web pages scroll smooth; 1300 nits peak brightness keeps the 1080p 6.67-inch screen readable in direct sun, though 395 ppi density means small text edges are slightly soft.

camera

108MP main, f/1.8, 8K videoThe large sensor (1/1.52", 0.7µm pixels, PDAF) captures detailed daylight shots; 8K recording at 30fps is available but chews storage and needs a stable hand or tripod, while the 119° ultrawide is useful for groups and landscapes.

battery

4520 mAh, ~1 day moderate useExpect roughly 5 to 6 hours of screen-on time during mixed use (browsing, messaging, some video); the 33W charger tops it to 100% in about 52 minutes if you start from zero.

durability

IP53, Gorilla Glass 5IP53 protects against vertical water sprays and light dust but offers no submersion; the 7.8mm thickness and 196g weight sit between slim flagship and solid build, and Gorilla Glass 5 scratches more easily than newer versions.

connectivity

5G Sub6, Wi-Fi 6e, NFC5G bands 1, 3, 28, 41, 77, 78 (SA/NSA) give good coverage in most regions; Wi-Fi 6e and dual-band WLAN keep speeds competitive, and NFC enables mobile payments.
