1. All the major apps will be accessible.
2. All live TV channels of Sony and Star are not present now but after merger with Star they may be available.

Nat Geo, Nat Geo wild , Star movies select, star movies and their HD versions . all the kids channels like super Hungama, Disney HD, Disney Junior etc are not present on Jio TV + rest all are present including regional ones.
Sony Pix HD and Sony BBC Earth HD are also not present. Times movie channels like MNX, Movies Now and their HD versions are also not present. BBC,CNN are not present along with cartoon network HD , pogo etc.
IN 10 all channels like Epic , Showbox etc are available only through App. All discovery channels are also available through App. Eurosports is now not available in APP.
Some live TV channels open through App and that takes some seconds which is OK with me ( Hope they convert all of them directly in future). google play app is not available but major apps like fancode etc are available with subscription.
On the advantage side there are many channels which are not available anywhere. Refer my 1st post for updated channel list of Jio Fiber in my thread .
3. My experience is too excellent with only 1-2 downtimes due to external issues ( not because of Jio). I am with the backup plan 10 Mbps with box and pay only 400 Rs per month for all services taken during IPL offer . I am only using 2 mobiles ,1 TV and 1 Tab on the fiber internet and they work fine .The box is not laggy for me and UI too is excellent with remote everything working excellent. You can control through My Jio APP . I performed troubleshooting 1-2 times on jio remote through How To videos and remote issues got resolved accordingly. The billing and other alerts are regular and excellent .There is also the option of converting to universal remote.
