My iPhone 6 was great up until last when the screen started clicking out of nowhere. I went to the store, and they replaced the screen. Great, but now I had weird light leak issues (top right was dark).. went in a 2nd time, and they completely replaced the phone. This time the bottom half of my screen is yellowish, while the top half looks normal. Can I just deal with Apple customer service instead of making trips to the store? It's quite far and I haven't got the time.
