Bug/trick allows playing Pokémon GO in landscape mode
Note: The following is not my own work. I copied and pasted it from another website. My understanding is that I cannot post links to sites that are not in the Mobile Nations network, hence my omission of a link to the site where I obtained this information. If you must read the material at the site where I found it, you can send me a PM and I will share the link (if I’m allowed to do so).
I have personally tried this and it works.
Step 1: Fire up Pokemon Go and turn your iPhone into landscape mode and keep it in that orientation throughout.
Step 2: Tap the Poke Ball at the bottom of the screen.
Step 3: Tap Settings in the corner of the screen.
Step 4: Scroll down and tap “Report High-Priority Issue.”
Step 5: Tap “Yes” when asked if you’re sure that is exactly what you want to do.
Step 6: Your iPhone will then be kicked out into Safari to load the Pokemon website. We don’t actually need that, so press the Home button.
Step 7: Fire Pokemon Go up one more time and marvel at its landscape-ness.
