nexus 4, after screen replacement

so guys i need help
broke my display on nexus
ordered new one from ebay, ive changed it, everything went smooth, didnt damage nothing coz i was paying a lot of attention and was carefull
but since then ive met 3 problems, when you send a message, all sent messages appears on the top and recieved on the bottom, i mean sent messages goes from the top to the bottom and received from the bottom to the top.
second problem: when you make a call, screen turns off, even if youre not talking anymore still cant see nothing, if you press power it blinks for a second and goes back black untill other person wont hang up
third problem that came after i rechecked all contacts, now when u turn it on it goes Google, then 4 dots hanging on the screen and thats it, so basically its not starting
please i really need to solve this because right now im with an old iphone and it kills me
