Weak GPS, weak UMTS Internet
Since I replaced my screen on my iphone 4 I am experiencing issues with GPS reception and UMTS Internet.
Sometimes GPS seems to work fine, but more often it completely dislocates me a few hundred meters of my actual position.
Also, UMTS Internet (e.g. through MP3 streaming or Webbrowsing) seems to be weaker than before.
Wifi on the other hand still seems to work perfectly.
Do you have any idea what could be the cause for this problem? I checked the screws on the antenna cover (from Weak GPS Signal Signal) but all the screws are in the right place. Do you think that putting the PCB in the oven could fix my problem?
Thank you for your help!
Is this a good question?
