I had my soft keys dead for a about a month. Read various blogs and articles and how to fix them. Finally ended up using tools like floating soft keys and pie controls.
I knew, it was because of power fluctuations that my soft keys were dead. There was nothing i could do about it. But today to my surprise they started working absolutely fine. I tried and analyse what happened to make it work. Following was different than everyday and one of these was what fixed it. Anyone with soft keys unresponsive issue can try these and confirm if it works for them.
1. I did not charge my phone with the cable slightly broken at the edge. (It charges just fine and the wire is not completely out but could have been the issue.
2. I did not charge the phone for a full stretch of 24 hours. Luckily did not run out of battery.
3. Charged only using use on my computer/laptop.
And so far it has been acting normal and haven't noticed any unresponsiveness since.
Try out and let me know if this simple thing works for you.
