Please who buy samsung s24 ultra mobile the display has many issues

I bought samsung s24 ultra mobile less than five days ago I was using samsung s22 ultra but s22 ultra display is better than s24 ultra display.

The Samsung s22 mobile that I am using does not work while answering an incoming call and the display does not turn on every time when I double tap.

I am using Samsung S22 Ultra, When I entered into no signal area, network not found , after coming back to the signal area still it not shows signal. Signal cames only after restarting the mobile. I raised this complaint several times.

After updating Samsung s22 ultra to Android 13 stable version when ever I went to the no signal area  tower not came, after coming to the signal area still it shows no signal, my mobile network settings are in automatic option still not getting signa...
