I was really getting annoyed that my Samsung Galaxy S5 would reboot as many as three times a day. The reboots would occur, oftentimes, at the most inconvenient times. One day I sat down and using my Mac laptop, I perused the Internet looking for a solution. Nothing came to light except one weird report that some individuals thought the problem was a local cell tower problem. I used that tip to find a few cell phone settings that might relate. Following is my last two day notes which reveals the single culprit.
March 26, 2016,
- BATTERY: I checked my battery for not being flat and it was perfectly non curved.
- SYSTEM UPDATES: I checked for system updates and it is up to date.
- SMART NETWORK: I turned off Wi-Fi > Smart network switch to see if this is the cause. This automatically switches between Wi-Fi and mobile networks to maintain a stable Internet connection.
- PASSPOINT: Under Advance options (upper left corner screen options) I also turned OFF Passpoint.
- VoLTE: Select Phone main menu item at the bottom of your main screen. Once Phone is selected you will see 4 menu items at the top of the new screen. Highlight the Keypad and you should see all the numbers for making a call. To the right are three vertical dots. Press on those 3 dots and then choose the following: Settings > Call > Call Settings. Then choose Voice over LTE settings and then “Do not use VoLTE”.

- In over one week, only one cell phone restart. I was on to a solution but which of the 3 was at fault?
- PASSPOINT: To narrow the problem down, today I turned ON Passpoint.
Settings > Wi-Fi > Advanced.
- VoLTE: I also turned ON VoLTE.
- SMART NETWORK: This left Smart Network still turned off. For me, this was the problem.
Solution: From what I read, Smart network switch has had problems. Once I turned off Wi-Fi Smart network, my cell phone only rebooted once since April 8, 2016.
This is how you can turn OFF the Wi-Fi Smart network switch:
- Press your screen Settings application which looks like a spiked wheel.
- Choose Wi-Fi once you are into the settings.
- Once you see the Wi-Fi screen look at the top of that screen and you should see “Smart network switch”. Turn that off. This automatically switches between Wi-Fi and mobile networks and also between 2.4 GHz and 5 GHz bands, to maintain stable connection.
Give this a try and if it does not work for you, come back and follow the above directions to turn this back on. Good luck to you.
