Why doesn't the speaker work when using apps after I updated my iPhone 4S to 6.1.2

I've seen many people with this issue. Poor iPhone 4S users. Anyway, as long as its not on silence, it should work. If not, it is a software glitch if it worked before and I am not able to help you. Hopefully Apple patches this soon.

Same issue after I updated to 6.1.2. Ringer/music doesn't work on speaker but does using voice memo. The phone is now useless (due to apple) I can't get an appointment at the apple store for days. I've tried to get help in apple community's but "roaminggnome" who was rude, was no help. We have no appreciable help in sight either. Each update has had worse issue than the previous for me. Help!

I upgraded my iphone 4S to IOS 6.1.2. Since doing this I've completely lost all sound function on my phone. Also, the volume buttons have become disabled. Every update Apple has been doing has been making the situation worst. I'm eligible for an update and have been on the fence about getting another iphone or getting a Samsung Galaxy 3. The Galaxy is looking like the better choice.

Same issue here with 4S upgrade to 6.1.2. I told my wife to hold off...thank god. She would be far more upset with me.

iOS v6.1.1 sucked... not 6.1.2...they should have caught this in QA during the first couple of minutes of testing. Volume = nope, reject and send back to dev team. done.

Nice to know that i am not the only one having this issue on my phone, and its very unfortunate for us. I moved my sim card to a spare phone and used my iphone 4S as paperweight until FIX will be released!

Bad Apple! Fix 1 problem and cause more problem.

My volume issue has been resolved. Played with my phone all day... tried plugging in power and headphones, unplugging (maybe 100 times, lol), rebooting the phone and issue persisted.

Then tried this...was listening to TuneIn Radio, without closing, pausing or stopping the stream, I unplugged the headphones and the missing volume slider re-appeared, paused, but visible. Pressed play and it worked. LOL

Checked Music, Video and yes...Angry Birds...now the volume slider appears as if nothing was ever wrong. Hmmmm. Scratching head but happy volume in now working.

Immediately after updating my 4s to 6.1.2, I lost my volume bar and ability to use the volume buttons on the side of the phone that control ringer volume, etc. I did not lose the ability to hear phone calls or the alarm. This issue mainly affected my ability to listen to music and videos.

In my instance, the volume bar and ability to use the volume buttons returned when I did not have service to make phone calls, etc.

I tried restarting the phone and resetting the settings. No luck. I also tried blowing into and cleaning out the ports. Still no luck.

When I described the issue - and the interplay with the service - my boyfriend suggested that I put the phone into airplane mode. When I did this, my volume bar and ability to use the volume buttons returned. I then switched off airplane mode while keeping the music playing and - so far - I've restored my volume bar and ability to use the volume buttons while my phone has service.

I'll repost if this solution stops working.

This is VERY similart to the issue I have with my Ipad3 after installing ios 6.1.2 - I 'chated' with the Service Organisation, and they didn't seem to recognise this, but it seems a common issue with ios 6.1.2 - hopefully they'll fix it soon - it seems to afftect BOTH iphones AND ipads.

it dint work for me 😟

still no reply from Apple... hope they fix SOON! its so frustrating missing calls. what a useless phone!

But has APPLE accepted that its a bug and they working towards the fix.??
