After the latest software update, my Samsung phone (F545G) has started showing a serious issue. Both Wi-Fi and Bluetooth turn off automatically again and again. I didn’t have this problem before the update.
What I am facing:
Wi-Fi turns off on its own
Bluetooth also switches off automatically
Happens multiple times a day
Restarting the phone doesn’t fix it
I don’t know whether this is a software bug or some internal hardware issue.
If anyone has faced this issue or knows a proper solution, please guide me.
Thank you.

Dear Samsung Member,

Greetings from Samsung Customer Support!

We regret to hear about your experience with our product. Please believe that this is not a usual occurrence.

Please perform the below-mentioned troubleshooting steps, these may help in resolving your concern.

● Check Settings: Do you get any error pop up, on connecting your device to a Wi-Fi network?
Note: Any prompt that says "Authentication Error" is related to an incorrect password. Please contact your Internet Service Provider for assistance regarding changing your Wi-Fi network password.

● Forget the Network: Settings>Connections>Wi-Fi>Wi-Fi network> Tap and hold the Wi-Fi network that you're having trouble with until the menu allows you to select Forget Network.

● Reset Network Settings: Settings>General Management.>Reset>Reset Network Setting.

● Restart the Router and Mobile Device: → Switch off your Router (at the wall or with the power button on the router) and wait for 2-3 minutes before switching it on. While you're waiting, press the Power button on your mobile device and select Restart.
→Once the router has been successfully connected to the internet again, try to connect to your network on your mobile device.
→ Make sure there is no interference between the router and your mobile device. Concrete walls, fridges, and microwaves can all interrupt the Wi-Fi signal.

→Check Flight Mode by swiping down notification panel on your device with two fingers to access all of the Quick Settings.
→Find the Airplane/Flight mode option and turn it off.

→For Bluetooth issue kindly follow the below steps:

● Reset app preferences: Settings > Apps > More option > Reset App Preferences.

● Kindly try to connect your device with "other devices" and check.

● Clear cache: Settings > Apps > Menu > Show system apps > Search and type "Bluetooth" > Bluetooth > Storage > Clear cache > Clear data > OK.

● The clear cache memory of a particular application: Settings > Apps > Now pick the app that you like to clear off the cache memory > Storage > Clear Cache.

● Reset settings: Settings>General Management>Reset> Reset all settings to their default.

● Reset network settings: Reset Wi-Fi, Bluetooth, and other network settings to their default.


● Disable flight mode: → Kindly check and disable the Airplane/Flight Mode on your device.

● You can reset your device by following the steps.
1. Kindly create a data backup of your device via the SMART switch mobile application or http://www.samsung.com/in/support/smartswitch pc suite.
2. Remember the Google password before resetting the device because it is required during initial setup.
3. If you do not remember the password advice you to reset (Forgot password) your Google account.

Path: Settings> General Management.>Reset>Temporary cloud backup or External storage backup>After backup tap on Factory data reset to reset your device to its factory default settings.
This will erase all data, including files and downloaded apps.

If the issue persists, kindly report the problems with a log file.

Warm Regards,

I’ve been facing the same issue for the last six months after a recent software update. My Samsung F23 has started restarting continuously in a loop, and I’m unable to use the phone properly.

The service center advised me to replace the entire motherboard, which costs around ₹9,000 — but the device was in perfect working condition before the update. This seems to be a software-related problem rather than a hardware failure, and it’s been very frustrating.

Here are the main issues I’m facing:

Wi-Fi and hotspot not working

Continuous restart loop

Slow and unstable network connectivity, especially in 5G mode

Phone overheating


It’s possible that the issue is caused by incompatible hardware drivers that are not fully compatible with the latest software update. I kindly request you to look into this matter and verify if the update is causing these problems. Please provide an appropriate solution or guidance, as many users are experiencing similar issues.

Our hard-earned money is valuable, and it’s disappointing to face such problems on a working device after an update. I hope Samsung takes this feedback seriously and resolves it at the earliest.

Thank you for your attention and support.
