I have a Samsung Galaxy Grand Prime which hangs every time switch on my Mobile data/Wi-Fi. Why is this? It requires restart every day otherwise it hangs. How do i get out of this problem? Please help!!!
Welcome to Android Central! Try booting into Safe Mode, which temporarily disables all 3rd party apps. The steps on the Grand Prime are probably the same as on the S4: https://support.t-mobile.com/docs/DOC-11724
If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.
I use Google Chrome browser and I am not seeing any issues. I would try clearing the cache and data for the application and if need be uninstall and reinstall it.
