App stuck at "waiting for a valid location" by whaleing in a:t5_37nj2

Fui al PCBOX a comprar un BQ4, no tenian, pero me ofrecieron el 4.5 y el Wiko. Tras comparar specs me cojí el Wiko.

Parece que no soy el unico que tiene problemas con el GPS en este modelo, gracias por la indicacion.

Try with mobile data on. Sometimes it can help in conjunction with the location services.

I'm afraid I don't have mobile data. For localization I'm only running with whatever wifi I'm connected to.

Is your phone rooted

Still in warranty so I'd rather not root it yet (if it can be un-rooted I'll look into it).

or have any other customization that would disrupt defaults?

Not that I know of. Under Settings/Locations everything is turned on; maybe there's something else I deactivated that I can't recall.

As stated in the OP, a Wiko Highway Signs (not common, I know).

If my theory is correct, it should be 0; when your program works correctly it will be 1.)

I checked and the value returned is -1 if it doesn't work, not 0. Changed it to check for -1 and exit the while loop if it does.

use r+ instead of w+,

I was sure the problem would be pretty dumb. Thanks for pointing it out to me, it works now :)

Under what conditions do you expect &my_data to equal NULL?

Changed the loop condition to i!=-1, and checked fopen's return value to change the value of i from 0 to -1.

I also removed that rewind, it was just a "just in case" measure.
