iPhone x freezing

I have problem with my iPhone X, after I changed back glass it started to freezing but its not like you cannot do anything whit that, its like I went to settings after first freezing, tap on general then tap on reset and it happend again, you can only go to home screen and try it again after like 5-10 seconds, sometimes it works but its very annoying, and I have also problem with Apple Wallet I cant launch it, When I try to launch it on home screen I just got black screen for like 1-2 minutes and than it crashes, when I tap Apple wallet in setting, the whole bar its grey like I am holding finger on it and nothing is happening and all you can do is swipe to home screen and try it again and again byt nothing is going to happen and App store is broken too in this phone because I want to instal something and when I tap on blue button buy or what you have there in your languange, I only got spinning circle and nothing is happen and yes I checked my connection and it was perfect. I dont know what should I do so I am asking you for help, that what part should I replace in that phone if nothing would help.
