I have had my Samsung Galaxy S5 for about a year now and it has been working fine until a few days ago. I would use my wi-fi when I have access to it and then I would switch to my 4GLTE when I don't have access to any wi-fi. This has been working for the longest and I only had to switch to 4GLTE when I'm at working or driving. But recently, my phone would not switch back to 4GLTE when I lose wi-fi connection or even turn off the wi-fi option on my phone. Restarting the phone would temporarily fix the issue but I was wondering if there is anything else that I can do?
I got the phone from T-Mobile but I been using MetroPCS ($60 unlimited data plan) since about 2 months after using T-Mobile.
