NeoTeo's verdict
Which of the two is the better buy
The Oscal Tank 1 is the pick for performance, screen, cameras, and battery capacity: its Dimensity 7050, 16 GB of RAM, and 20,000 mAh battery put it well ahead of the Blackview Oscal FLAT 2. The FLAT 2 is much lighter and thinner.
The Tank 1’s screen has 1080 px horizontal and 2460 px vertical resolution, plus a 120 Hz refresh rate; the FLAT 2 has 720 px, 1612 px, and 90 Hz. Their builds differ just as sharply: the Tank 1 weighs 640 g and is 29.5 mm thick, versus 192 g and 8.7 mm for the FLAT 2. The Blackview is easier to carry.
The Tank 1 pairs a 64 MP main camera with a 50 MP front camera, while the FLAT 2 has 13 MP and 8 MP, respectively. Its 20,000 mAh battery dwarfs the Blackview’s 5,000 mAh, and 55 W charging beats 10 W; it also supports reverse charging. The FLAT 2 is the better buy only if it costs less.
