Help i9300 on its last legs

[treforest]

Hi everyone! First post, thanks for having me.

My S3 seems to be dying. It has the following problems:

* it is really hard to get it to charge (some cables better than others)
* people can't hear me very well during calls
* sometimes it drops the network (mobile phone network I mean, not wifi) (a reboot fixes this).

Any ideas on how to fix gratefully received.

Best wishes and happy holidays

Try a factory reset first. If that doesn't help use Odin to re install the whole firmware for your model and carrier. You can find firmware on sammobile.com

OK thanks. Have tried factory reset, did not make any difference. Will try the firmware also. I think it might be a hardware thing, as has stayed the same across ROM changes (Cyanogenmod to Replicant).
