AT&T Galaxy S6 update seemed to fix my signal issues
Shortly after I upgraded from the Galaxy S5 to the S6 I started having severe problems with the phone. I didn’t necessarily want to stay with Android, I wanted to go back to Apple, however I had purchased a Galaxy Gear watch early this year and I didn’t want it to become useless.
With the S6 I started having problems maintaining a data connection, even if my device said I had full bars and LTE. The internet would simply stop working on the phone for no reason. I would try turning airplane mode on and off and occasionally this would work for a few minutes, but the data connection would slow to a crawl and be entirely useless. This would happen at work and all throughout Boise where previously I had a strong signal everywhere. This issue was so frustrating because I had grown to rely on having an internet connection in my pocket wherever I went and now it felt like I went back to having a flip phone. I would also experience dropped calls even when I had full bars.
I talked to AT&T tech support and they couldn’t come up with any solutions, and in the end they referred me to Samsung tech support. I talked to Samsung who also were no help and denied that this issue even existed despite there being forum posts all over the place from users experiencing the exact same issue.
Yesterday my phone took an OTA update, a 146MB update that changes the build number from OE2 to OF3, and now it seems my phone is functioning normally again (knock on wood!). I hope this was the fix because I was seriously about to just go out and pay full price for an iPhone 6. If you were experiencing the same issues go ahead and update your phone and let me know if the update improves anything. Best of luck!
