The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.

Android Authority's launch-day report gives the shipped specs: "6.0-inch 2,880 x 1,440 P-OLED", "2,700 mAh" and "3,520 mAh" batteries, "octa-core 2.35 GHz Qualcomm Snapdragon 835", 4 GB RAM, IP67 and the 12.2 MP f/1.8 camera.
TechCrunch similarly reports Google confirming an October 4 launch via its own ad campaign and landing page, again one day earlier than the pin's stored 5 October date.
Fortune reports Google scheduling its Pixel 2 unveiling event for 4 October, one day earlier than the pin's stored 5 October date, a discrepancy likely reflecting the difference between the announcement event and the device's actual on-sale date.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
