Are haptics in every android equal?

[Parvesh Khatri]

There are different android devices around, more than the number of people I have seen in my 21 yrs life. Brands started giving different types of haptics a few yrs ago. The vibration motors on older android devices are the same, hurrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr,    keyboard typing feels kinda like hmm, hmm, humm humm humm.

If I want to add good haptics in my android application, does I have to test on every android device with a haptic motor like Apple's taptic engine?

Or if I make it to create a "Tap!" effect, it will feel like a "Tap!" on every device with a haptic motor?

every device will be different, but not different enough that it will really matter.

Having android phones from Samsung, LG, Sony, and Motorola, they’re nearly all different.

They are mostly the same, biggest difference IMHO is between ultra budget phones (50-100$) and all other phones heh.

No, but I strongly recommend following material design principles:

And using haptic feedback constants:
