Who even uses YouTube? Try the vanced one bro

It has something to do with google backup...try installing google photos and check if u find those pics there

What do u mean by only?? ... people are still living with 1-2Mbps ... he has the best possible internet speed through mobile data!!!

I removed it 2 years back from my redmi and Samsung phone... it's a very old trick...and fyi u are not uninstalling them... U are just disabling it.... Just go to play store and search for them u will find enable as the option 

Did u just root ur phone or installed any other os?
