I totally agree...lot of people changed their home button paying up to 80€!! And finally its clearly a software problem!!
To all people here who paid for changing the home button if i would be you i would claim the costs showing this thread.
Hopefully they pay you the money back...
Until now i was never afraid of doing an update, i believed in Apple costumer service. Now we know we cannot trust.
Like it's not even posible to go back...
The worst, i claimed in Apple bug reporter, the telefon hotline but until now nobody asked me if my phone is ok now.
Nobody never recognized that there is a "homebutton bug" in iOS8...This is really a no go...I hope they will improve this again..
I changed to Apple to save time, but this time calculating useless "restores" of my phone i can buy a android phone as well...
