Hello Nisha Lini,

Well, if you are searching for Indian top youtube channel for hacking then you can refer to the YT channel of Infinity Hacks of Prasant Asoliya ( https://www.youtube.com/channel/UC-qM4Yx4a3SgkaVsITguIXA )

His Paid Advance Android Hacking Course is definitely good...

Also if you are searching for just a good course and comfortable in English then you must go to Udemy courses as they provide a quality content and here is a recommendation by me ( https://www.udemy.com/course/the-complete-android-ethical-hacking-practical-course-caehp/ ) Rest you can search yourself as per your specific need...

Hope This Helps, and feel free to ask any further query...
