Speaker phone option is greyed out

Apple is aware and will replace your phone if you bring it in. They just replaced mine so this thread was very helpful - thanks!

I'v had this problem with iPhone 6 (ghosted loudspeaker button) and replacing the AUDIO (codec) IC solved it.

"If only 1 Mic, or 1 component isn't working correctly, most likely a bad component...Mic (Charging Flex), Ear speaker (Front flex assembly or ear speaker) etc...

But when you are greyed out, or if multiple issues with Mic or speakers, most likely a board level repair by replacing or reballing Audio Codec (IC)."

I had the same exact problems listed above. I started talking to apple support via phone Saturday April 26th and all they could offer was to back up my phone and restart it as new phone and see if it worked. That didn’t solve the problem. I took it to Apple on Wednesday and explained what was going on, and all he did was again restart it back as a new phone which didn’t solve the problem. Apple rep was not helpful at all. Only suggestion was buy a phone from directly from them for $319. I said no. Took it to an off brand iPhone repair shop and they confirmed that upgrading to new IOS killed my microphone, speaker & board (?) and there were software issues detected. They avised me to get a new phone and also to get insurance going forward. Especially if you get the X as the screen is $550 to replace. Not exactly what I wanted to hear, but off brand repair shop was way nicer and explained more than apple rep. So I took the defunct phone to att, asked for a new phone and traded in my broken phone. I also did NOT mention it was broken. I just wanted to get rid of it the easiest way I could. Frustrating situation to say the least, but feel better having a phone that works. I feel for everyone who is going thru this problem!

"I experienced this problem this week. My phone is a 7+ that I've had for 16 months so definitely out of warranty. Two days ago I suddenly couldn't use my apple headphones (not bluetooth), I couldn't hear out of the earpiece and the speakerphone and add call options were greyed out. I tried several different things: upgrading to 11.4, restarting several times, backing it up and wiping it out, and restarting over and over (even though this now took twice the time it took before the issue).

I contacted the apple support via chat online, they then set me up with a genius bar appointment. The guy at the store knew what it was immediately. They have to run a diagnostic on your phone to make sure there are no other damages to it and if it checks out they will exchange your phone for a refurbished model. I was lucky that they had mine in stock, and I didn't have to pay but the cost is $349 if for some reason they try to charge you."
