HTC One X not saving contacts & continuous reset of ringtone.
Hey everyone. New here, so apologies if this may be in the wrong section.
Anyway, for the past month or two, I'm not exactly sure, my HTC One X will not save contacts - I'll add them into my phone, save the number, and then it will delete them after a few minutes. It's quite frustrating, and I haven't found anyone with the same problem as me so far. My searching as yielded fruitless.
My phone also will reset my ringtone after a while - not as quickly as deleting the contacts, but after a week or a few days I'll notice my ringtone changes back to some really bad default one. Quite annoying indeed.
My phone is currently version 4.1.1 Jellybean and there are no updates that I can install, according to my phone.
So any help would be appreciated here, guys and girls. Thanks in advance.
