If you work in a factory or farm then it’s likely dust or particles built up in the speaker grills on your frame. Try cleaning these out with a toothbrush and see if that makes a difference. Also while it might sound dumb, was there film covering the new part? Sometimes replacement parts come with film over parts of the new components.

When I was first working on phones I had trouble getting the home button connected correctly on the iPhone 8 Plus. Both the 7 and 8 lines are very similar and the home buttons connect exactly the same. For me the problem was that I did not have the connector plugged in correctly even though it appeared to be. Another explanation is that the home button extender cable on the new screen is not working. Did the repair shop you took it to try a new screen? After checking the home button for physical damage I would try reconnecting the home button then I would try a new screen. If that doesn’t work then it may sadly mean that your home button is broken. In that case you will either always have to use a digital home button or replace your phone. There are also Bluetooth home buttons available however I’m not sure how good they work. If you can not get your original home button working you will also loose Touch ID.

It’s possible the battery needs to be replace. Well, that is if it can be replaced and if it’s actually worth it. A bad battery could explain why the device is getting hot. There might be some internal protection that is causing the device to then power off to prevent damaged or a fire risk.

Where did you get the battery from? If you got it from iFixit they you will be covered under warranty. To me this sounds like a bad battery. You’re phone is on the older side some some of those batteries could have been sitting around for awhile. Lithium Ion batteries can sit around for a decent amount of time however they are still loosing charge and this can cause major problems from them. I see this happen from time to time when we repair devices even with a product that comes from a reputable vendor. Get a replacement and you should be good to go.

Unlike Apple, Samsung does not screw over their customers when it comes to the fingerprint scanner. You can safely swap out this part with no effect on the function at all.

If your batteries are completely dead they likely are shot and you need new ones. How do you maintain your batteries in the off season? If they are not on a tender they will continue to drain down. Once the batteries hit below around 12.5 volts, sulfation on the plates inside the battery starts. This causes permanent damage to the battery and once that happens they will never come back. Protect your investment when you purchase your new batteries with a battery tender if you do not have one already. Good properly maintained batteries can give you sometimes up to 10 years out of the batteries.

Honestly, parts will probably be hard to find and if you do, they will likely be around the cost of the device itself.

Not sure on iPads but on iPhones if the device does not have a home button connected to it this can cause this issue. Not sure but it’s possible even with the new button that the device can’t tell it’s connected. The new button should not make a difference other than Touch ID not working. Return to home should still work.

First, rice is a myth. While the theory makes sense, it just creates a huge mess inside the device. If the device was fully submersed in water then the battery likely needs to be replaced. It’s also possible the screen needs to be replaced as well. These are the two common things that needs to be replaced in water damaged devices. What you really need to do is get the device opened up and get any water out of the device and clean up any corrosion that may be starting. If you don’t have the skills or tools to do so take it to a local repair shop that does water damage recovery work.

Here are my thoughts looking through what other have posted. I ran into an issue where I was working on an iPhone 7 and tore the home button extender cable because the screen slipped on me as I was opening the device. It’s possible that’s what happened here. Was the screen an original part from Apple or was it a replacement? It’s possible that if it was an aftermarket part, there could have been some damaged done already and reopening the device finished it off. A few other thoughts are pinched cables can sometime cause odd things to happen but it sounds like a new screen solved the problem. There is a lot of room to play with the connectors on the screen on this model but you always need to be aware of how much tension you put on the cables as well.

This guide does not show how to do a factory reset but rather shows how to force the device to restart.
