After installing Android 5.0 on by Note 3, my cell signal strength got much worse. At home, where my signal was decent but not strong before, I can no longer make calls. If it does connect, voice quality is poor and the signal drops constantly. I often cannot even send SMS messages now because of poor signal strength. Often, even when I go to an area with good signal strength, my phone will not connect, and I have to reboot it to reestablish a cell connection. At work, where I used to get full or nearly full signal strength, I now get only one or two bars. My daughter has a Galaxy S4, which she luckily has not updated to Lollipop. Side by side, it gets much better signal strength than my upgraded Note 3. What did the OS update do to the cell reception? My phone has become almost useless. Is there any way to fix this?
