I already have reported for some time, but it didn't solve....it was all okay for that update... can any of you help me in this matter???
Please follow the easy troubleshooting steps which might help to solve the Wi-Fi issue.
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.
1: Settings >> Connections >> Wi-Fi >> W-Fi network >> Tap and hold the Wi-Fi network that you're having trouble with until the menu allows you to select Forget Network.
3: 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.
4: Disable flight mode. Find the Airplane/Flight mode option and turn it off.
kindly perform some basic steps which should resolve the Bluetooth issue.
1. Menu>apps>settings icon>connection>scroll until you get more connection settings>nearby device scanning>turn it on.
2. Reset app preferences: Apps screen>Settings>Apps>More option or on three dots at the top right corner of the screen>Reset App Preferences.
3. Try to connect your device: 1. Open the settings app>connections>Bluetooth. 2. This screen will display all the devices you have connected to in the past as well as all available devices. 3. Tap on the device you wish to connect.
Please note: Most Bluetooth devices need to be actively paired to be displayed as available devices. To turn on Bluetooth pairing refers to the instructions for your specific device.
4. If the issue still persists, try to connect the Bluetooth device with another smartphone. If the same issue persists then, it means there is a problem with the Bluetooth device.
5. If the issue has not been resolved then clear paired list: Apps> settings>connection and turn on Bluetooth>setting option along with the paired device>unpair.
6. If the issue still persists, clear the cache and data of Bluetooth app data. Apps>settings>apps>Filter and sort>show system apps>Tap on "OK">>search and type "Bluetooth">Bluetooth>storage>clear cache(Note: Clearing the app cache is kind of like a cleanse for your apps. It will get rid of residual files that could be slowing down the app) >>Clear data(Note: Clearing the data will reset the app to factory default settings. Any personal settings saved on the app will be removed)>>Tap on "OK"
