Please tell me your Phone's Codename
Every cellphone model and variant has a unique codename.
I am particularly interested in a:
Pixel XL codename 'marlin'
Pixel XL2 codename 'taimen'
LG G3 codename 'd855'
LG G5 codename 'd850'
Moto G7 codename 'river'
Moto G7 Plus codename 'lake'
Samsung Galaxy S7 codename 'herolte'
Samsung Galaxy S7 Edge codename 'hero2lte'
Samsung Galaxy S8 codename 'dreamlte'
Samsung Galaxy S9 codename 'starlte'
Samsung Galaxy S9+ codename 'star2lte'
How to Find the Codename
On most Android phones.
Press and hold the Volume Down button.
Press and hold the Power On button
The phone will boot to "Fastboot Mode", with the Android robot lying on its back.
The line: "Product/Variant: <codename>...", has the codename.
