Home button on iPad doesn’t work

I am having a problem with my iPad. The home button clicks in but doesn’t register. This happens every time I come home at night and it doesn’t happen at a specific time. It may take like 30 minutes for the home button to work again and maybe in the morning to find out it doesn’t work again. Touch ID still works fine and tried all the methods online and sometimes they worked (maybe pure coincidence) and sometimes they just doesn’t work. I am covered by apple’s limited one year warranty but I would want to avoid getting a new iPad if possible.
