Thank you, everyone, for your helpful replies! It seems that I am going to be unable to make either of these phones pick up GPS as they are and flashing stuff (which I know nothing about) sounds like more then I can handle. I will return the phones and get my refund and then.. I still need a phone. I've done more research and I just feel severely overwhelmed. It was a big enough deal to find this phone and finally decide to buy it and now I have to go through that all over again :( Would it be OK to change this into a discussing on where I could get an Android phone with 2GB ram for under $300max (camera power doesn't really matter, battery life does matter, NFC doesn't matter - never used it for anything before, storage space doesn't realllly matter but would like a microSD slot)?
So far I've found:
$299 MEIZU M3 note - hardware looks fantastic but I am unsure about the strange OS, I really just wanted Android 5.0.1+ (again, I don't know much about this stuff/flashing etc and wouldn't really want to mess around with that kind of stuff if it meant I couldn't return the phone if something went wrong).
$299 Huawei P8lite - hardware is smaller/lesser but has 2GB ram and is already running Android 5.0.2 which is a big plus.
$299 Samsung Galaxy S4 Brand New - what I originally wanted but 'new' this time, but again, how do I know this isn't an import which is also going to have GPS issues?
$240 DOOGEE HOMTOM HT7 Pro - something random, my last phone was a THL so I'm not adverse to randomly branded phones if they are going to do the job, has 2GB ram and running android 5.0.1 which is good.
Or, any similar phones any of you would recommend that would fit my needs? Thanks again folks, the above answers helped me work out that I really do need to return the phones as getting GPS to work on either of them may never work.
