Every time I use Touch ID my phone thinks I click the Home Button

Who replaced the battery? If it was someone without sufficient expertise, they may have damaged something. You don't have to live in the U.S. to get service on your iPhone (unless that's where you purchased it). Apple offers service in many countries. However, if someone unauthorized has opened the phone, that avenue may be closed to you.

I am no expert, but I know how things work. I replaced the battery. The issue with the home button isn't always there, trough. It appears 4/5 times and it may be unfixable.

Well, it's certainly unfixable by Apple now. Sorry.

And what could Apple do to fix it? They would just replace the home button. And beacuse every iPhone is coded to its original home button, TouchID would stop working after the replacement, which is worse.

Not true. When Apple repairs a home button, they can repair it and it will continue to work properly.

True. The button would work, yeah, but I doubt it that they would made a home button especially for me. So TouchID would not work (fingerprint sensor)

Yes, it would work. Apple, and only Apple, can replace a Home button so that Touch ID continues to work properly.

I didn't damage anything. The damage done to the phone was caused by seawater and corrosion.

I see you can't back up your "facts" so don't tell me that I damaged the phone myself.

NO, the seawater did the damage. If you had taken it to Apple immediately theye would have replace the whole phone for $229. Now they won't touch it.

She was telling you facts. Apple doesn't have the home button coded to your particular phone by hardware. It is done in the software and they have the ability to recode a new home button to the phone. The problem is that apple will not fix it now that you voided any warranty by replacing the battery yourself. That is the point she was trying to get across but you kept missing it.

I would take it to apple store for options in terms of repair

Done here. As you've already opened your phone and most likely damaged it, this is a pointless hypothetical discussion.
