Cannot access any settings pages

[Kianee23]

Trying to connect new headphones to Galaxy Tab A8 and I cannot access any of my settings pages as they all close down too quickly. 

I've read that I might need to clear the crache however I can't open the 'general management' page. It only stays open for a millisecond before it closes down. 

Help appreciated please

What brand of headphones are they? Did they come with an app or are they just connected via Bluetooth?

Try holding down the Power and Vol Down until the Tab reboots and see if hat helps with settings.  If not boot to Safe Mode and try it.  If it works in Safe Mode the one of the apps you installed is causing it. 

Lastly to clear the system cache

Turn off the device 

* Connect to a computer via USB 

Press and hold Volume Up + Power buttons simultaneously till the device logo appears 

When it logo appears, release Power button but hold the others few more seconds 

Release all the buttons when Recovery Mode screen appears 

You can use the Volume Up and Volume Down buttons to scroll up or down, and the Power button to select 

Using the Vol Down rocker, select Wipe Cache Partition 

Press the Power button to select  

Use the Vol Down button to select Repair Apps 

Use the power button to select 

Use the Vol Down button to select Restart 

Use the power button to select

* Some devices need to be connected to a computer in order to enter the Recovery Mode.
