Not able to use 5g for my samsung s7 plus tab ... when is the update coming .?

It's been 8 hrs after unboxing and charging it full .. my s22+ 256gb variant even after 1gb update is heating and lagging 梁imagine spending 85k for this and facing these kind of things already  .. I have restarted it twice .. no help at all

How can we use Google discover instead of samsung free on galaxy tab s7+ lte version ?  I have turned off the samsung free already but I want google's .. if anyone know how to do it 

I'm having a massive issue in scanning my fingerprint... as these days everything is biometric protected  I'm facing a huge problem  in it .. after atleast 7-8 attempts of my right thumb it detects the prints and as far as left thumb is concerned it ...

With all the one ui 4.0 already out for a52 series even .. I still haven't got any update for my galaxy tab s7+ ... just feel like being robbed for premium tab with no nfc as well
