Water damage, no taptic function- but does this mean bad Touch ID too?

So I accidentally took my iPhone 7 underwater in my swim trunks for about 5 minutes, and it was probably 3 feet or so under.

Phone still works, however it claims "Unable to activate touch ID on this Iphone" when I reboot it, and I get no vibration from the taptics functionality. I know that taptics engine is likely shot and needs replaced, but sine it's saying "Unable to Activate touch ID", is it just saying that because the engine is shot, or is that indicating that the touch ID function of the button is shot as well?

In other words, is it possible that JUST the taptics engine is shorted out, and if I replace that, the touch ID functionality will return? Anyone have any stories of seeing this message when JUST the taptic engine was burned out?

I have the same problem just wondering what did you end up doing? How did you fix it?

So I had a life proof case thinking that it’d be water proof and brought it into a hot tub and the home button doesnt let me press it but Touch ID works any answers, and its a regular iPhone7

Thanks for the answers guys. However both the touch ID and the home button seems to be malfunctioning. Neither of them work. Right now I'm using the software version of the home button.

What I'm wondering is if I replace the Taptic Engine only, well that return functionality back to the home button as well as the touch ID functionality? I don't want to buy both parts if I can avoid it. I'm just curious if someone has had the same experience and just replaced the taptic engine and was successful in getting both the home button and the touch ID working again by just replacing back.

Or is it likely I'm screwed and have to replace both pieces?

I had washed my phone with soap and water because of all the shower water that got in the case

If I have a water proof case for the 7, but it doesn’t cover the home button, will it be ok if it goes in water? I’ve tested the case and it works, but the open home button scares me

The root cause is dead home button, or contaminated connector/ board, not taptic engine.

On iPhone 7, the home button is entirely solid state instead of a mechanical switch. It has a capacitive touch sensor, a fingerprint sensor and a force sensor. Data for at least fingerprint and touch run on an encrypted SPI link.

In order for the system to register a home button press, touch sensor and force sensor must send valid data at the same time. the phone simulates the pressing and releasing of the button with taptic engine vibrations. The taptic engine is just an iron weight driven by magnetic coils, it is unlikely for it to actually break.

My suggestion is to take it to Apple if you want the phone to be repaired at all. It is possible that Apple missed water damage signs and just replaces the phone for free, if they do notice however, the price will be $319.

If you decide to repair it yourself, please note that there is at least 70% percent chance that you can't do any improvements. Since iPhone 7 home button is all digital and requires both touch and press to activate, the replacement button not only destroys fingerprint, but also as a button itself. In other words the replacement button is ABSOLUTELY USELESS. If you find out that the root cause is indeed fried home button or board, unless you can somehow restore the original parts to working order, you can't repair it in any sense.

Tom, how would one go about repairing the home button themselves ?

Would you look on the physical home button or on the logic board for the issue ?

On the iPhone 7 the home button is not mechanical, it uses the haptic engine just like the screen does so if your home button is responding then the haptic engine is functioning. If only you Touch ID is being affected you may try cleaning off the home button to remove any dirt or deposits from the water. If that does not work since the phone is rated as water resistant I would take it to the Apple Store and see if they may swap it out under warranty.

The OP could certainly try but Apple Support specifically states:

This Warranty does not apply: ...(d) to damage caused by accident, abuse, misuse, fire, liquid contact, earthquake or other external cause; ...

https://www.apple.com/legal/warranty/pro...

On their Technical Specs page, they also say the following:

iPhone 7 and iPhone 7 Plus are splash, water, and dust resistant and were tested under controlled laboratory conditions with a rating of IP67 under IEC standard 60529. Splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear. Do not attempt to charge a wet iPhone; refer to the user guide for cleaning and drying instructions. Liquid damage not covered under warranty.

That is the Canadian version but I'm sure it applies worldwide.

I would certainly try...it can't hurt.

I figured it couldn't hurt, I actually edited the answer when I noticed it should still be under warranty. To add onto my answer Ted until you go to the Apple Store do like Minho said and do not charge the phone or even turn it on as any electricity can cause more damage if moisture has gotten inside the phone. If the warranty try does not work take it to a repair shop that offers water damage treatment. If you take it to a shop ensure you ask how they perform the process. To give you some pointers they should do the following:

-Remove the screen and battery

-Remove the logic board

-Perform a thorough inspection (Under a Microscope) to look for corrosion

-The logic board should be run through an ultrasonic cleaner (Not a jewelry cleaner) with proper cleaner.

-The logic board should be hand cleaned with IPA and dried thoroughly before re-assembly.

In my experience I have found on several occassions that there is more than likely contamination on the connector (where the button connects to the screen) it is clearly visible beneath a Microscope & probably noticeable using a good quality Magnifying glass.

using 99% alcohol & a toothbrush clean the connector (do not douse the connector, alcohol has a tendency to get beneath the screen & cause damage) make sure the connector is both dry & clean & then reconnect the home button..

I find that at least 50% of water damage Home Button problems on Iphones (inc Iphone 7s) can be remedied by cleaning the connector

I can not stress highly enough to need to disconnect the home button connector cautiously!!

the Home Buttons are very easily damaged whilst trying to remove them (the Flex is very easily torn!!)

if the flex is torn then you will open a completely different “Kettle of Fish”

I hope this is of help

Can a charger damage an iPhone in less than 24hrs of use?. Please I need responses

I put my iPhone 7 in a bucket of water and exposed it to jets of water , then left it in the bucket filled with water, I knew it was low on charge and it’s gonna die later I wiped all the water out and used paper to remove water out of the charging port and plugged it in , it turned on and when I tried to unlock it with Touch ID , I couldn’t because the home button became hypersensitive, then used the passcode to unlock my iPhone , I knew the home button was screwed thanks to the water , later the home button stopped working completely but Touch ID was functioning, I also saw a white diagonal line on the screen , after googling I learnt that it was due to water damage , I then freaked out and tried to heat my phone to get rid of all the water by charging it with screen on full brightness and video playback, but it was of no use I noticed another mark on the screen after that , It was 11am, I left my iPhone 7 next to my bed leaning against the wall and turned on the fan hoping it will dry out the water within the phone , when I woke up I turned on my iPhone 7 and found that all the lines and marks on my screen were gone and the home button was hypersensitive and not dead , I then left my iPhone under the sun for 7 hours , hoping that all the water within my iPhone 7 will evaporate , that evening I turned on my iPhone 7 and found that home button started working just like new and Touch ID didn’t seem to work but after rebooting Touch ID started to work and my iPhone 7 is just the way it was before I put it in water , thankfully it was fixed.
