Bluetooth and S Pen is not working on my Note 10+ how to fix this problem Please help me 

After upgrading camera is too worst So much noise, blurry, laggy, focusing is mind blowing 勞 worst. What I'm using Sam's s20+ mobile cam or Chinese mbl. Pls resolve the camera issue

I didn't get any major changes in my mbl, same as previous version.But Software information displays 13, one ui4 We get only Lil bit chances with 2.5 gb Upgrading. I am totally disappointed  with this Upgrading.So funny of Sam we bought 70k to 1 lak...
