S9 Wi-Fi And Bluetooth Does Not Turn On

Problem: Hi I’m using a Samsung galaxy S9. Android version 8.0 There seems to be an issue with the Wi-Fi and Bluetooth. It doesn’t seem to switch on at all. The issue has been going on for days. I went through the steps to find out if it’s a software issue. Apart from factory reset. My fear is if I do this I may lose some data. Is there any way to figure the issue out? Is it worth taking it Into a repair shop and asking them?

Solution: It’s very likely that this problem is caused by a faulty Wi-Fi/Bluetooth chip. You can however check if the problem is caused by a software glitch by doing a factory reset. Make sure to backup your phone data before doing the reset. In case the problem still persists after the reset then you should bring the phone to a service center and have it checked.

S9 Not Connecting To The Internet

Problem: Hi there ! I hope you’re doing fine. me not so much to be honest, my brand new samsung S9 2018 (less than a month old), doesn’t want to connect to the internet even though it is connected to my wifi, I tried disconnecting the wifi and only use 4g (mobile data) but same problem appears. It shows in the far right corner that it is  connected but no data is actually exchanged so I appears like I have no internet at all which is odd. I tried restarting multiple times but I does not work. I thought that maybe my wifi was freaking out but my 5 years old Iphone 5c can still access youtube and all. I thought that maybe it is hardware related but I can still receive and send text messages. Once on campus I tried connecting to my Uni’s wifi and it still cannot work. Do you maybe have an idea as to why this is happening ? Should I  go to the store to have it replaced (I bought it last month so I still have a warranty) or a factory reset should do the trick?

Solution: The first thing you should do in this case is to check if the problem is caused by an app you downloaded. Start the phone in Safe Mode then check if the issue occurs in this mode. If it doesn’t then it is likely caused by a downloaded app. Find out what app this is and uninstall it. In case the problem still occurs even in Safe Mode then you should consider doing a factory reset. Make sure to backup your phone data before doing the reset. Once the reset is complete check if your phone has the correct APN settings so that you can access the mobile data network. If the problem still persists after the reset then you should consider having the phone replaced.

S9 Mobile Data Keeps Disconnecting

Problem: I have an issue with my S9 that T-mobile can’t figure out. I bought this unlocked phone thinking I would be switching to other carrier from T-mobile in the near future. That plan has changed, but I like my phone so I kept it even though I am on a T-Mobile Plan. The problem is that the It keeps losing the network. I will have plenty of service, but the Data will not stay connected.  I am not sure if it is a related issue or not, but I can not receive group texts or image texts regardless of whether or not I am on wifi, or on the rare occasion when mobile data happens to be working. Any help would be appreciated.

Solution: The first thing you need to do in this case is to make sure that the APN settings of the phone is correctly set.

To access your phone APN settings

  • From any home screen, tap Apps then Settings.
  • If using Tab view, tap the Networks tab.
  • Under ‘WIRELESS NETWORKS,’ tap Mobile data.
  • Tap Menu then Mobile networks then Access Point Names.

Make sure to check that your phone has the following settings

  • Name: T-Mobile US LTE
  • APN:
  • Proxy: <Not set>
  • Port: <Not set>
  • Username: <Not set>
  • Password: <Not set>
  • Server: <Not set>
  • MMSC:
  • MMS proxy: <Not set>
  • MMS port: <Not set>
  • MMS protocol: WAP 2.0
  • MCC: 310
  • MNC: 260
  • Authentication type: <Not set>
  • APN type: <Not set> OR Internet+MMS
  • APN protocol: IPv4/IPv6
  • APN roaming protocol: IPv4
  • Enable/disable APN: <greyed out unless there are multiple APNs>
  • Bearer: Unspecified

If your phone has the correct APN settings but the issue still persists then this could be a network related problem where the mobile data signal is weak in your area. You should contact your carrier if this is the case. You should also consider doing a factory reset to eliminate the possibility of the problem being caused by a software glitch. Make sure to backup your phone data before doing the reset.

S9 Cannot Connect to Wi-Fi Network

Problem: Dear Droid Guy,Hopefully I have reached the end of my quest… I am from the Netherlands (the ‘Other’ country), and I am (was the proud) owner of an S9. The original carrier is T-Mobile, judging from the IMEI, which was confirmed by T-Mobile here in the Netherlands. The phone was rooted when I got it (a hand-me-down from my daughter…), and of course I succeeded in deleting some files, with the result that the thing would not work anymore. After having tried numerous images, stock ROMs, would-be stock-ROMs, CMW and TRWP recoveries, always the same result. I even had the thing restored to the original firmware but after 4 hours I gave up: no start screen. I have the American version installed now . I can connect to my home network but, yet again, cannot get onto the Internet. I do NOT (and really do not want to) use data over mobile networks: a simple bundle will suffice for me. And the problem has nothing to do with my SIM-card, which I have been using for over a year now, before the problem manifested itself. Apparently some files necessary to connect my phone to the Internet through WiFi-network(s) are missing; could this have to do with any radio or modem files? I am rather desperate now, so, could you help me, please?

Solution: If you have deleted some files from the phone and it does not connect to the Internet over a Wi-Fi connection anymore then the best thing to do right now is to flash the phone with its stock firmware file using Odin. You can get this file as well as the instructions on how to flash your phone from the Sammobile website. If the issue still persists even with the stock firmware installed then this is most likely caused by a faulty hardware component. The best thing to do right now is to bring the phone to a service center and have it checked.
