Home Button Not Working - Which Route to Take?

Error 53 is luckily history for long time now. If you replace your home button you will lose touch ID but clicking will still work as expected. If you take your phone to Apple for a screen repair they’ll fix the touch ID too, but you’ll have to pay a nice bill..at today’s market conditions close to the iPhone residual value. It’s more an economical choice than anything else. You can still try making a backup and do a factory restore to rule out possible software glitches. You may also open the iPhone and inspect that everything looks fine, reseat connectors in place and even replace the screen metal shield plate with home button cable attached..if you don’t try you will never know what’s wrong..try and error is the only possible approach but will cost you time and spares.
