Razer phone 2 out of warranty repairs

Does anybody know if it's possible to get out of warranty repairs done by Razer? I can't seem to find a way to contact them since my Razer phone 2 is well out of warranty. I'm having trouble with the GPS and I think the battery is about done. Also with the GPS is it possible to re-calibrate the compass? Kinda wondering if that would fix things with that part but I haven't been able to find any kind of instructions on that. I've tried it some newer phones but... I dunno I just can't seem to like them as much as my old one so is really really like to get it fixed. Thanks for the help and for taking time to read this. It's much appreciated.
