I recently upgraded my phone contract and got a new phone, Galaxy S6. Since I got it (around 20th July this year) it was just fine, except that it would overheat sometimes and turn off for no significant reason, but I thought it's just an Android being silly. During that time I got some scratches, barely noticeable, and also I scratched one corner. Today the phone was acting just crazy - first it took ages to connect to the wifi, tthen it suddenly died (still not connected), and when it turned on, the starting screen was a bit glitchy. I don't have pictures, but it was just random colours and lines. The menu screen was fine, but when I tried to connect to wifi again, it did the same thing and then the menu screen was bright red rather than pink and looked glitchy as well. I panicked and plugged it in for charging, but when I tried to turn it on it didn't do anything. After a while it turned on, but was still glitchy. Now I don't know what to do. Is it something that I can fix, or do I have to take it to the manufacturer. If so, will they repair or replace it since it's damaged on the outside? Thanks a lot for all the answers.
