7. Do I need to install Dolphin Jetpack separately if I have already installed Dolphin Browser?
You only need to install Dolphin Jetpack separately if you do not meet the below requirements. Otherwise, Dolphin Jetpack is already embedded into Dolphin Browser, and can be accessed from the settings.
Dolphin v11.3.4: Android 4.0+
Dolphin v11.1.7: Android 4.1+
Dolphin v11.1.6: Android 4.2+
