So, I have an application I'm trying to use, and on one phone, the buttons are soft-buttons on-screen, and on the other phone, the buttons are hardware buttons.
On the hardware button phone, when I launch the application, I don't see the triple dot to open the menu (The phone has the Box [hardware button] and Back Arrow). On the software phone, there's the triple dot on the screen (Triangle, Circle, Box, Triple Dot).
I think my generic question is enough to answer the question, but here's the rest of the details if you're one not afraid to read the less relevant details:
The application I'm trying to use is: KTSync
The phone with software buttons is: Motorola Moto E
The phone with hardware buttons is: Samsung Note 4
Edit: Firelord suggested this, which works perfectly for devices you can access with ADB, but in my case I'm looking for how to do this without ADB:
adb shell input keyevent 82
