I had this problem. I realized that it wasn't actually a problem with the tablet. The case it was in was putting too much stress on the tablet, and this inhibited the home and other keys. Once I took it out of the case, it was fine.

I have the same problem, does this mean that we can't put the tablet in a case ?

による

You're right! I tried to put it off then it works! Put it on again, the home-search-back button not working again!

による

I just read this post because I was experiencing the same issue. I removed the case and boom all is working again! THANK YOU!

による

Same here...took it out of the case and now it works just fine

による

It's not "stress on the tablet"- it's the magnets in the folio that are affecting my device.

Hi Guyz,

Its very simple way to get rid of this problem.You just download an app from play store named as

"Back Button (No root)" install it and enjoy the functionality of all buttons like home,back etc.Its actually helpful if your androids menu main menu buttons are not working.

or you can search via browser here it is :-

Thanks,

One of the most common reason to android home button stopped working is system OS update or screen replacement. Let see some possible solutions that can fix home button not working on android phonehttps://www.bestusefultips.com/home-butt.... Also software key problem is the common hardware problem after update OS.

First of all restart your android phone or tablet. If not solve then try below solutions.

Fix home button not working android Nougat, marshmallow, lollipop:

Factory reset android phone:

Step 1: Open “Settings” app on your phone

Step 2: Tap “backup & reset” under personal section

Step 3: Touch “factory data reset

Step 4: Tap on “Reset phone

If you have a set screen lock on your device, you’ll need to draw pattern, PIN or password to unlock it.

Step 5: Tap “Erase everything

It will erase all data from you device’s internal storage

Step 6: When your device has finished erasing, select the option to reboot your device.

Step 7: After complete process, restore your data.

Reset android phone in recovery mode / Wipe cache partition:

Step 1: If turn on your phone, switch off it

Step 2: Press & hold the volume down button and the power button at the same time until the phone switch on.

You can view the Android system recovery screen on your device. By default “start” button seen on your android nougat 7.0.

Step 3: Press the volume down button until see recovery mode

Step 4: Press the power button to restart in recovery mode

You can see the above screen of android robot with red exclamation mark (red triangle) on phone screen.

Step 5: Press volume buttons to scroll to “wipe cache partition”, press the power button to select it.

This message seen on the screen: Wipe cache?

Step 6: To confirm, use volume buttons to scroll to “Yes” and press the power button to select it.

Clearing the cache data may take 1-2 minutes.

Step 7: Use the volume buttons to scroll to “reboot system now”, press the power button to select it.

I hope above given troubleshooting steps fix your home or power button not working android phone or tablet.

I've also had this problem intermittently - have taken it out of its Bluetooth keyboard case (after a full factory reset seemed to have no effect at all) and it seems to be working... will see if it reoccurs! Thanks - I was nearly going to send it back to Samsung to try and get it fixed!

I had this happen to, I flashed the rom 4 times and even tried a 5.1.1 rom and still no back button.

I reflashed my rom back to 4.2.2 and all is good.

I haven't seen any fixes yet but personally, I hate lolipop anyway.

Also had this problem and like a previous comment said, it was the magnet on my case that made it stop working. I folded the magnetic flap so that it would be easier to hold the tablet. Once I unfolded it and just let it hang there, the buttons started working again.

I had the same problem with my galaxy after I replaced the screen, was really annoying, tried a few things first like factory reset updates install uninstall, nothing worked so I replaced the usb docking port circuit board whatever you call with the help of YouTube and it has worked fine ever since, the component was only 8 quid! Buzzing!

Your battery is saving power,so get in there and turn off the restrictions in the Power Saving mode. I was worried too,I trust that you would figured it out.

Update (06/04/2016)

Your phone when to Power Saving mode, and that will restrict your lights, apps, etc. Go to your Power saving menu and toggle it off
