Galaxy s10 vs s10 5g build materials

[scantrell33]

Does anyone know if the glass used on the galaxy s10 is different on the galaxy s10 5g. I have the galaxy s10 5g and the back cover feels almost like plastic not hard like the s10

I just realized it's TRUE it doesnt feel like glass back on the s10 5g
