My phone is having problems saving and editing contacts. As far as I know, I don't have a lot of contacts, only 20, so I don't understand why it won't save new ones. And also, if I try to change the name of someone or change the number, that won't save either. This is becoming a problem as I have resorted to save the numbers and names onto a notepad app. My phone hasn't exactly... worked a lot, as I have had various other problems regarding music and speakers, etc. But this problem is sort of recent so... yeah. I don't know if this is relevant but I did accidentally format my SD card recently, around the same time the problem but I just don't understand why it is doing this. Please, if anybody has anything that could help me it would be deeply appreciated.
