This information comes from TENAA database. Most of the specs align with the picture painted by leaks and gossip already available, although at least one of its elements is drastically different than predicted:
– 6,5′ OLED display, QHD+,
– Snapdragon 855 CPU,
– 8GB RAM, 256GB space for data,
– 24 mpx selfie shooter,
– 52 x 26 x 8 mpx main camera, LED flash,
– 3680 mAh battery,
– Android 9 Pie,
– weight: 188 gram.
The main difference is in the phone’s battery: its rumoured size was 4400mAh. Oh well.
