Had my iphone for less than a month, updated the os last night and noticed this this morning, wondering if it supposed to be like this or is it screenburn or a glitch..
it is only the notes app that is doing it which is why i noticed it..
the black 'no' before 'notes' looks a bit like a shadow but none of the other apps have it and are all normal.
bit worried because my samsung started doing this and it ended up being screen burn, my entire screen had shadows like this then my screen went totally pink so if this is the same thing i still have time to send it back.
picture included when it loads..
