So, everytime i try to charge my phone it keeps coming up with this, it started early this week when i woke up to find my phone off and wouldn't come back on and came up with the battery charge and yellow triangle when i plugged it into the charger, i tried a friends S2 battery in my phone and it powered up straight away, woohoo new battery is all i needed... i thought, until about 10 minutes ago i was texting and my phone screen flickered, the phone turned off and i get this yellow triangle again when i try to charge it.
Google is all but useless, most references to the yellow triangle refer to rooting forums/problems of which i've never messed with anything like that...
I've just been onto T-mobile and i'm still in my warrenty period so i will pop into the shop tomorrow and see what they say, but i also have it insured through fonesure, would it be better to go through them?
feel lost now
Sorry for the horrible thread and if anyone as any advice, thank you in advance.
