Problem #1: Samsung Galaxy S5 keeps on scanning and won’t connect properly
Hello, my Wi-Fi keeps scanning for a network even though I have allow for scan & smart network switched off. Then when I am connected, my connection optimizer pops up with this message.
I’ve tried a soft reset a few times and I’m wondering if you have any options before I do a full on factory reset. Thank you! — Ryan
Solution: Hi Ryan. An issue like this can be due to a rogue app. Have you considered uninstalling apps prior to contacting us? If you haven’t, uninstall apps you have recently installed including the connection optimizer app you are using to see a difference. You can boot the phone in safe mode first and observe the phone for a few hours before doing the uninstall. This is a trial-and-error method of isolating the offending app so if nothing changes, you really have to proceed to factory reset.
After wiping the phone via factory reset, make sure to observe the phone and the Wi-Fi function for a few hours before installing apps.
Problem #2: Samsung Galaxy S5 hotspot function not turning on
I bought a new Samsung S5 and found out that I am unable to turn the hotspot function on as it gives a verification error message. Also, tapping the hotspot setting and under configure the network SSID is Verizon-SCL23-510F if that might help figuring what is the problem.
I read your article about that problem and the difference is that I checked with the service provider (Aldi who uses Telstra network). Also hotspot function was normal on my old Samsung S2 using the same provider. — Ashraf
Solution: Hi Ashraf. If everything checked out as far as potential billing and carrier issues are concerned, the issue might very well be on your hardware. Please get a phone replacement or have the phone checked by a qualified technician.
Problem #3: Galaxy S5 hotspot not working
I always use and have my hotspot on. My phone died, I turned it back in but now hotspot won’t turn on. It says unable to connect, no data connection available. The internet on the phone still works. I’ve tried taking the battery out, SIM out, checked settings but not seeing an issue. — Jackie
Solution: Hi Jackie. The thing that caused your phone to die might very well be the same reason why hotspot function has ceased to function properly. Try doing a factory reset to remove all apps and downloaded contents then run hotspot again. Here are the steps:
- 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 key 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.
Factory reset deletes everything from the phone’s internal memory unit so make sure your personal data are all backed up.
There’s a chance that one of your apps is the cause of the problem so after doing a factory reset, make sure not to install any app until you have tested that hotspot function is working.
Problem #4: Galaxy S5 cannot connect to work Wi-Fi but can to home and shopping malls’ networks
I can’t connect to my work Wi-Fi, but I have no problem connecting to home and shopping malls networks. I have also checked with the IT guy, he has not blocked me on the Wi-Fi.
I have done the clear cache, I have even restored to factory defaults, then I even upgraded the software to the latest and yet still my phone does not connect to the work Wi-Fi. it is an open network no passwords needed. The moment I try to connect it just go to save connection immediately. I have tried to forget the network, and re-add it everything, I am out of options…please assist….My phone have the Vodacom default McAfee on, but I am not sure if this could be the app that stops me from accessing the Wi-Fi… I have seen some people had McAfee problems, but I couldn’t find the setting they talked about, nowhere… Please assist? — Pieta
Solution: Hi Pieta. The best thing that you can do is factory reset your phone one more time try to connect to that Wi-Fi network without installing any apps. We are not familiar with how third party antivirus apps work so there’s nothing that we can provide when it comes to navigation and changing settings.
In the event that your phone will still be unable to connect to your work Wi-Fi after a factory reset, you have to work with your IT department to resolve it.
Problem #5: Galaxy S5 keeps losing Wi-Fi signal after updating to Lollipop
Since the update to Lollipop, when the phone loses its WI-FI signal, it will not automatically connect to mobile data. Switching on and off mobile data does not help, the only way to force a connection is to go into airplane mode and then back out. — Peter
Solution: Hi Peter. The new Lollipop update has not been as smooth as anticipated and problems can sometimes appear depending on the state of the phone during the installation. If you haven’t read our post Why Android Lollipop Causes Problems yet, we suggest that you do so you will be guided accordingly.
Basically, the solution for this may either be the deletion of the cache partition, or performing a factory reset.
If you don’t know how to delete the cache partition in your S5, here are the steps:
- Turn the phone off.
- Press and hold the following buttons together: Power, Volume Up and Home.
- Release the buttons once the Android system recovery menu appears.
- Use the Volume buttons to navigate to Wipe Cache Partition option.
- Press the Power button to confirm selection.
- Select Reboot System Now option after deleting the cache. Wait for the phone to reboot.
The steps on how to do a factory reset are provided above.
Problem #6: Galaxy S5 won’t connect to T-Mobile network
I just bought a Galaxy S5 off a Facebook group. I put my SIM in expecting everything to start up normal but it won’t connect to T-Mobile’s network at all. My IMEI is 35342406041655/03. My APN settings show fast.T-Mobile.com 310 and 260 default supl mms ipv4/ipv6. There isn’t an update available to download. I have wiped and factory reset through recovery and settings. What can I do to get this working? Model number SM-G900T. Baseband g900tuvu1anch Keenan 3.4.0-964333. — Kirstyn
Solution: Hi Kirstyn. The IMEI you have provided appears invalid. Please dial *#06# on your phone and check its validity in this site:
https://www.imei.info/. If everything checks out fine, make sure to call T-Mobile so they can provision the device properly.
Problem #7: How to fix Galaxy S5 randomly dropping Wi-Fi internet connection
Phone intermittently drops Internet connection. Internet connection is set to Wi-Fi. — Timothy
Solution: Hi Timothy. An intermittent connection problem can happen due many factors. You need to narrow down the possible reasons for the problem before you can work on a fix. There are two sides to this problem–a phone issue, or a Wi-Fi network issue.
Troubleshoot your device
Your first task is to verify if your device’s Wi-Fi is working normally. This can easily be done by connecting to a known stable Wi-Fi network for a few hours. If you have Wi-Fi at work, try observing how the phone behaves when it’s connected to it.
You also want to perform a soft reset by turning it off and removing the battery for at least 10 seconds. This will ensure that the system reboots properly. This is an effective solution especially if the device has been up for a long time.
After doing a soft reset, try to connect to your Wi-Fi again.
If the problem remains, do a factory reset. After that, connect to the network again without installing any third party apps. Some apps may create problems like the one you are experiencing. If everything looks normal, try to install your apps again.
Troubleshoot your Wi-Fi network
Checking your Wi-Fi network’s reliability can be tricky but the first hint you should watch out for is when other devices are having the same issue as your S5. if there’s another smartphone, tablet, or laptop dropping Wi-Fi internet connection, your local home network must be having some problems.
If a wired device like a computer does not drop internet connectivity while only wireless devices do, interference may be the culprit. Here are the things you need to consider when troubleshooting a wireless network:
- Distance and location of the router. Ideally, your router should be located in the center of your house to ensure the best coverage possible. A standard router can broadcast wireless signal for about 30 feet in all directions but the strength may vary especially if there are thick walls, metal objects, bodies of water like aquariums, re-enforced concrete walls, or any other similar objects along the transmission path. If possible, move your router in an elevated position so the signal is not hampered by mentioned objects.
- Other interference sources. The ubiquity of wireless devices nowadays means that a typical home with a Wi-Fi network is a crowded place. Devices with antenna are all sending their own signals possibly on the same frequency. This can result to either intermittent connection or total loss of connection. Baby monitors, Bluetooth devices like wireless mouse or speakers, cordless phones all use the same frequency as a standard router. Unless you have a dual-band router and you know how configure it to work with your devices, your only viable option is to turn off these devices. Heck, even your neighbor’s Wi-Fi can also interfere with your own!
- Other wireless devices. If you have a number of wireless devices connecting to your Wi-Fi all at the same, this problem can also happen. Multiple smartphones or tablets simultaneously streaming Netflix coupled with a gaming console running can result to low bandwidth situation. Bandwidth “hogging” is the most common cause of random connection drops or slow, intermittent connection problems at home.
If you need guidance on what you need to do specifically to address a possible wireless network issue, please contact your internet service provider.
Problem #8: Galaxy S5 won’t automatically connect to remembered Wi-Fi network
A few times a day when i leave work and come back or get home, my phone won’t automatically connect to the remembered Wi-Fi connection. When i go to settings it still has listed Wi-Fi signals from where i just was which sometimes are miles away and they’re live. I’m not able to connect to any of them but they’re there. Its stuck in scanning and can’t find anything. If I turn Wi-Fi off and back on it corrects the problem temporarily. I wiped internal memory and factory reset 3 or 4 times and odined OF5 because i was stuck on OE1. Then factory reset 3 times again as well as odin OF5 3 times. It was fine for 2 days and then it started again. Any help would be greatly appreciated. Thank you. — George
Solution: Hi George. As mentioned above, a factory reset may become useless if you install the same set of apps after doing it. Consider doing another round of factory reset and observe the phone for a full day without your apps to see if that will make any difference.
If that won’t work, we don’t know what will. You may have to get it replaced if you still can.
