Semi jailbreak benefits

These themes are different from Houdini Semi Jailbreak benefits.
Normally, Jailbreak requires device setting changes (disable Touch ID, enable Airplane mode, disable Find my iPhone ) / iTunes installations / Windows or Mac computer support / USB cable plugging / Third party software installations. But Semi jailbreak never asks to fill its.
At this time untethered jailbreak not available for latest iOS 9.3.4 version. So Semi jailbreak is the only option for it.
Some jailbreak tools are specific for one computer operating system Ex- TaiG jailbreak released iOS 8 - 8.1.2 jailbreak only for Windows. However, Semi jailbreak not requires computer support.
Some jailbreak tools, not compatible with OTA (over the air) firmware upgrade. Example Pangu jailbreak not compatible with OTA and iOS users should use iTunes update method before use Pangu jailbreak. But SJB works on OTA updates.
