Hello everyone,
So I got my screen replaced after I broke it and was recently in the bathroom and somehow the iphone 7 came in contact with the water for like 2 seconds. I quickly threw it off on the bed. After I came back from the shower, I saw that the phone was automatically rebooting. I thought it's updating the firmware but later "Your home button needs to repair" popup came up with assistive touch. The Touch ID was working fine & the the silent/loud switch was giving vibrations when toggled.
I put the phone in rice bowl ( I know it doesn't work but maybe placebo effect :P) and kept it there overnight. Morning i took it out, blew hair dryer for like 2 mins and started the phone. Works without any issue. :)
