My phone keeps switching from Data network to Data roaming…even in the drop down menu. I’m not incurring additional charges but I am getting a continued annoying pop up notification telling me my device is trying to connect. I think the issue lies with the fact that I bought my phone abroad and although it was unlocked it sees my new home network (in Ireland) as foreign. I have tried several things like re setting my device…changing default accounts in Google wallet upgrading my device but the problem persists. The annoying thing is I am connected to a TV so when I use Netflix the pop up stops the device. I am unable to click on the pop up in order to stop it. Please help. Thanks. — Paul
Solution: Hi Paul. The firmware running on your phone right now may be the cause of the issue so your best bet is to root the phone and to install custom ROMs to give you more control over otherwise inaccessible settings.
If you need the specific steps how to do these things, simply them via Google and you should be good to go.
I recently updated my S5 software to Lollipop and since then I cannot get online at all. My situation is a bit different because I have two phones currently and I don’t have a SIM card in my Galaxy S5. I’ve been able to use it for a computer of sorts getting online, working on Google drive with using only the Wi-Fi connection in my home. I tried the soft reset and it didn’t correct the problem so I guess I might need the factory reset? I didn’t want to try that step until I could ask you for any other possibilities to fix it. Thanks in advance! — Ileana
Solution: HI Ileana. If the problem started happening right after updating to Lollipop, try booting your S5 in safe mode first. This will prevent possible problem third party apps from running. Once in safe mode, try connecting to Wi-Fi again. If the problem fails to occur while in this mode, start uninstalling third party apps until the issue is gone. These are the steps to restart in safe mode:
- Turn the device off.
- Press and hold the Power key.
- When Samsung Galaxy S5 appears on the screen, release the Power key.
- Immediately after releasing the Power key, press and hold the Volume Down key.
- Continue to hold the Volume Down key until the device finishes restarting.
- Safe mode will display in the bottom left corner of the screen.
- Release the Volume Down key when you see Safe Mode.
You can also wipe the cache partition of the device to ensure that no corrupt or leftover files from KitKat are causing problems to the system. Here’s how:
- Turn off the device.
- Press and hold the following three buttons at the same time: Volume Up, Home, and Power.
- When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
- When the Android System Recovery screen appears, release the Volume Up and Home keys.
- Press the Volume Down key to highlight wipe cache partition.
- Press the Power key to select.
- When the wipe cache partition is complete, Reboot system now is highlighted.
- Press the Power key to restart the device.
Mobile data will not automatically connect after a Wi-Fi signal drops out. In the notifications, Mobile data is highlighted, but if I go into settings it says Mobile Data State disconnected. The only way to turn mobile data back on is to turn airplane mode on and off again. This is an annoyance as I regularly miss out on time critical updates I need when at work etc. If you could help with a solution that would be appreciated. — Craig
Solution: Hi Craig. Samsung has added a built-in feature in their S5s called Smart Network Switch to seamlessly switch to mobile data once a device is outside a Wi-Fi network. If you this enabled but it’s not working properly, try wiping the cache partition (steps provided above). Refreshing the system cache via cache partition wipe usually fixes this trouble but if not, perform a factory reset to revert all settings to defaults. These are the steps to do a factory reset:
- Power down the Galaxy S5.
- Press and hold the Volume Up button, the Home button, and the Power button together until you see the Android on screen.
- Use Volume Down to highlight the wipe data/factory reset option and press the Power button to select it.
- Use Volume Down again to highlight Yes – delete all user data and press Power to select it.
- Use the Power button to select Reboot system now.
- When the S5 restarts it should be completely wiped and ready to set up again.
By default, smart network switch is OFF so make sure to turn it back on after a factory reset. Here’s how:
- From the Home screen, tap Apps icon.
- Tap Settings.
- Tap WiFi.
- Untick the checkbox next to Smart network switch.
When I connect to Wi-Fi then go out of range with Wi-Fi my mobile data completely breaks and a have to restart my phone for it to work again. Only started happening recently. I have read your forums and turned the smart network switch off to see if that helped but it hasn’t. If you could please get back to me with a solution that would be fantastic thanks. — Sean
Solution: Hi Sean. That’s strange. Have you tried doing the standard software troubleshooting like the one we provide for Craig above? If you haven’t, please do so and let us know whatever the result will be.
I’m wondering if you can assist with some issues I’ve been having with my AT&T Samsung Galaxy S5 Active. My phone is scanning for networks almost constantly. It will scan every 20 seconds or so, even if I have Smart Switch turned off. It is draining my battery if I have Smart Switch on, and I’m using too much data if I turn off Wi-Fi. Even on Wi-Fi, it still scans and doesn’t give me a good connection. It acts pretty weird when I attempt to load anything or stream music. It will come up at first, and then just load, load, load, and nothing ends up loading. As soon as I turn off my Wi-Fi, and connect to 3G/4G, anything I’m loading comes right up. My brother has the same phone, and is having the same connection issues. We got both phones from AT&T, although he is out of town most of the time and still has connection issues like mine. He is also having an issue where sometimes his numbers on the lock screen turn into square characters or fade out and just disappear.
PLEASE HELP! Thank you! — Elizabeth
Solution: Hi Elizabeth. Looks like the phone is suffering from a firmware glitch. We haven’t heard of this issue before so this may be isolated to AT&T devices. Try wiping the cache partition and doing a factory reset to see any difference.
There’s also a possibility that an app may be the cause of this bug so you can also try to restart the phone in safe mode to see what happens when only the core apps and functions are allowed to run.
I have an S5 that has been rooted so I can connect my laptop. It has worked perfectly. Then all of a sudden, yesterday I couldn’t connect to my Hotspot. Thought it was my laptop, but after frustrating hours, I checked my Galaxy Tab and it couldn’t either. At first it doesn’t even pick up the network. I have to hit refresh multiple times, then shows it with no signal. When I click on it, it says checking network settings, then can’t connect to network. HELP! I have a girl scout meeting tonight and no way to print anything off my wireless printer!
Thanks for any help you can give me. — Donna
Solution: Hi Donna. We apologize if our solution does not reach you in time.
Was there anything that was changed in your S5 prior to noticing the problem? Did you update it or some apps before the trouble start? These are important things that you should check as they may hold the key to resolving this problem. If, for example, you updated an app before, consider uninstalling the said update and check what happens next.
It is also necessary to check if there are any account- or billing-related issues that may cause the internet in your S5 to stop working. You can check this by calling your carrier to ensure that the hotspot service is still active.
