My family just switching from sprint to tmobile. As a result i had to give up my iPhone 6 64gb for an iPhone 6 plus 128gb. Lately i have noticed my iPhone getting hot in the upper right hand corner. None of my previous phones have done this. Im not doing anything processor or grafic intensive. Just texting calling and the occasional snapchat. I have called apple and restored which has caused me to lose all of my stuff pretty much. i can't go to the apple store until this weekend because i am 15 and don't drive. The phone isn't like getting too hot to handle but too hot for my taste i guess you could say. please help me
