The first hint is a photo of Razer founder Min-liang Tan with Tom Moss, the general manager of Razer's Mobile unit. Inside Tan's pants is a product with a green Razer logo, it could definitely be a phone. Tom Moss was the co-founder and CEO of Nextbit, a smartphone company that
was bought by Razer in January 2017.
A firmer clue is a GFXBench profile that got spotted by Phone Radar. The listing shows a "Razer Phone" with Android "Razer Edition" 7.1.1. The device features the 10nm Qualcomm Snapdragon 835 octa-core processor with a frequency of 2.4GHz, the Adreno 540 GPU, and a 5.7" touchscreen with a 2560 x 1440 pixels resolution.
Other features include 8GB RAM, 64GB internal flash, a 12MP digicam, a 8MP front camera, Bluetooth, GPS, WiFi, NFC, an accelerometer, barometer, compass, gyroscope, and light sensor.
Take it with a grain of salt as the listing could be fake, but there are definitely a lot of clues here that we can expect a Razer smartphone on November 1.
