Welcome to Android Central! Photosphere requires a gyroscope, which the Zenfone 4 doesn't have, so it won't be possible.
I really doubt it. Photospheres require the phone to know if it's pointing up, down or straight ahead. That requires a gyroscope. I don't think any of the other sensors (like the accelerometer) can emulate that.
You could always try installing it from Google Play Store. If the Play Store says it's incompatible, it probably also needs a gyroscope.
Do you have a link to the apk?
