I got my screen changed!
I recently got my screen changed on my iPhone 7 plus. Now my speaker, to hear people while talking, and finger print button won't work! Also, my screen is dim in the lower right corner. The phone still works but I fear it will stop working in the near future. I brought it back and he said the phone was defective and that I should bring it to apple... He also told me not to tell them I got it fixed! They will know that the screen has been changed. I don't know what to do and I don't know if I should try and bring it elsewhere to get fixed and end up even more screwed!
