The text to speech stopped working. Also, making/receiving phone calls and calling the voicemail stopped working. I need to explain this part a liittle more though... On her phone, you can call someone, it will be dialling, without any dial tone, then once the other person answers the call, it immediately ends the call. The same thing happens if someone tries to call her. She gets the call pop up, but once she accepts the call, the call ends.
I almost titled this, "Galaxy S5 Text to Speech & Making/Receiving Calls Stopped Working," but as writing this I found that no sound is coming from the phone at all.
So, I'm guessing this sound issue is what's causing the other things above to not be woking.
I figured out the sound was the issue after remembering the dial tone didn't play if I tried to make a call with her phone. Then I went to her ringtones, but when cycling through the ringtones it wouldn't play their preview tones. Then I went to youtube and tried to play a video and no sound played even with all volumes turned to max. Bluetooth is turned off, btw.
Nope. All issues are still present in safe mode. Interestingly enough, though, the phone wouldn't give me the option to go into safe mode the way you suggested, but I got itinto safe mode the other way (by powering the phone off, then turning it on and holding the volume down button until it got to the home screen).
The phone also doesn't even play a sound on start up. Just vibrates.
I doubt either of those would be the issue, however it did give me the idea to see if audio would play if I plugged headphones into it... but still nothing.
I cleared the cache partition in the recovery mode. Regarding bluetooth, are you suggesting to see if it will connent to something else that should play audio?
Ya, I kinda figured a factory reset might be the only solution as long as it's not a hardware issue. Sadly, though, I cannot test the bluetooth sound because I don't have bluetooth headphones and I don't know where the power cord is to my bluetooth speaker. For now, she is trying out the Galaxy A01 just to have a phone that works until we either fix her S5 or she can get the S10+. Thanks for the suggestions and I will be sure to post again if the factory reset does or doesn't fix it.
