I had been complaining about the GPS issues with my phone in the past (read about it here). That's because I use them for navigating when I am driving the car. The GPS issues were resolved after buying the Galaxy S7 and disabling the My Optus app (read about it here). But I never talked about how I was mounting my phone in the car.
Initially, I ordered a Handsfree Bluetooth Smart Phone Holder from Kogan as per my cousin's recommendation. However, the ETA for it was a bit too long, so I cancelled the order.
I then went to the JB Hi-Fi and bought the Cygnett Dashview Universal Car Mount which was much cheaper and I could buy it on the spot. It wasn't a great product and the price probably reflects that. The arms of it which held the phone in place scratched the body of my phone's case because they were so tight. The tightening dial (I don't know what it is called, you just have to tighten it for the mount to stay fixed on the windshield) would loosen every now and then, although the mount never came off all by itself. But it at least got the job done.
But few weeks ago, I ran into a new problem.
I was in Beaconsfield and heading towards Melbourne City on the Monash Freeway M1. The phone lost GPS and never recovered. The phone felt hot and very sluggish, so I cleared all apps and when it didn't do anything, I rebooted the phone. Still it did not recover, so I just switched to my wife's phone for the rest of the trip. A few days before the first incident, I installed Optus Sports app to watch cricket on the phone. (I could use it freely with my plan) I thought that app messed up my GPS, just like the My Optus app did a few months ago. The phone had gotten a bit slow as well over the months, so I decided to do a complete factory reset and start from the scratch. I didn't get any issues with GPS afterwards, and I thought that it was just a software issue and that it was resolved.
And it occurred again on another day, around the exact area!!!
