Do you guys have the GPS issue?

My phone on 4.4.4 start to have GPS issue since a month ago, have been working fine since I got the phone end of last year until a month ago. Now its very slow to get a fix, and once get a fix, easy to loose it. Its quite easy for me to confirm that its a hardware issue as my wife's n5 from the same order do not have this issue.

Any of you tried this? I just ordered the ipod opener tool from ebay.
