This problem is a little trick. When this iPhone 5 unlock it is normal until 2s, after that some lines shows up and keep there. I have already replaced the battery, flex cable and the last one was the display from china. I really don´t know why the owner was so cute with this little iPhone. kkk Could anyone help me?
Thats 100% bad display, seen it countless times
If it’s not the display, which it sounds like you’re using cheap parts, then take a look at the digitizer socket, see if it looks clean and in good condition
