[Q] [HELP]Microphone and speakers stop working

I had been doing a great deal of tinkering trying to get my phone's battery life back in the last few days, and I made good progress, but I severely jacked up something related to the microphone/speaker/video recording.
PROBLEM:
The problem, as far as I can tell, is that every app that tries to access the microphone can't do it--this shows up when I try to use Google voice input in various text fields with a little "Can't reach Google at the moment." Same with trying to do a search by voice in Google Now--brief brief flash of the microphone red, then back to gray, with "Can't reach Google at the moment". Additionally, my Touchless Input cannot be enabled--the box has automatically unchecked itself, and pressing it makes the button get a little gray, registering the action, but no checkmark will appear.
Additionally, other apps which would use the mic don't seem to have that functionality--Evernote, for example, would crash if I attempted to record an audio clip. This was before I performed a factory data reset last night--and the problem has persisted regardless.
There are two other, seemingly related, issues. First is the inability of the phone to capture videos. The camera opens fine, and I can take fine stills with it, but pushing the video recording button makes the red "record" flash for a moment before a "Not able to record media" message pops up, and the camera returns to the still photo mode.
Second is the inability to play videos. I have tried playing videos in as many formats as I could try, from within several players, including the stock "Photos", "Gallery", and "YouTube" apps. "Sorry, cannot play video" pops up, or the app simply crashes. Similar story for attempting to play music through the stock "Google Play Music" app. And it gets worse. I can't make or receive calls. Actually, let me revise that. I can't hear anything being said on the calls, over the speaker, or through headphones (though I've yet to try BlueTooth). The call appears to connect, but I can't hear anything from them, and they can't hear anything from me.
So--that's the basic summary of the problem--threefold.
1. No audio input through mic
2. No audio output through speakers--my phone doesn't ring when I get a call, although it will vibrate and the options to take the call appear as they normally would.
3. No audio/video playback whatsoever for other media.
I'm running Android 4.4 on a Droid Mini, unrooted, and I just completed a factory reset last night.
ANALYSIS:
Here's the wrinkle. I know this isn't a hardware problem, because I have found a surefire fix that makes all of this work properly if I absolutely need it, it just sucks. Rebooting into safe mode is what does it. Playback resumes as it did before I had the problem. I can play videos, pump music, and Touchless Input works flawlessly--although interestingly, it has me re-enter the catchphrase three times every time I get into safemode, like setting up from scratch.
My consternation comes from the fact that, to my very limited knowledge, all that safe mode is doing keeping any user-added apps from running. Which is all well and good, but I just did a factory reset. Literally when I boot the phone no user installed apps are running, and yet there's a definite difference when I boot into safe mode, cuz everything works there.
So, safe mode must do something more than just disable user-installed apps--and I need to know what that is if I'm going to fix this thing. I have added 4 apps since then-- App Ops, GSAM Battery Monitor, BetterBatteryStats, and Button Savior (Non-root), all of which I know from experience to be very "well-behaved" apps.
Anyone know what safe mode is doing besides disabling user apps? Along those lines, does it revert updated stock apps to their factory state? I ask because very, very briefly, while my phone was slowly trying to upgrade the 40-odd pieces of Bloatware from the Play Store, the microphone was working. Which makes me think that the culprit is one of the system apps in it's updated form. If safe mode runs these apps as they originally appeared on the phone, that might explain it. It would also hopefully let me painstakingly disable these apps, one by one, to find the culprit and disable it.
I say culprit because of something I stumbled across trying to research this--weirdly enough, in a message from the devs of Shazam. devs of Shazam They say that the issue has shown up on 4.4 and the cause appears to be one app somehow monopolizing access to the microphone. I could see this breaking the video as well, and potentially the audio playback if, as I assume, Google uses the mic to help tweak the sound of the speakers.
Anyone know any more about any of the aspects of this? I will be posting back myself as I learn more.

What happens if you factory reset without restoring any apps? In other words, factory reset, choose not to restore your apps (or don't attach to a Google account on initial setup, and do it post-setup). In other words, do you have an app that is blocking this access?

Trying this now. Thanks for the suggestion!
Update: Tried this. Did another FDR, signed in to one of my Google accounts afterwards, but haven't updated a thing. The audio/voice/video/bugs seem gone; however, the ****ty battery drain I had before is back. I'm playing around with some settings to find out what can be done. I'm also going down the list and updating the system apps one by one.
Does anyone know a good testing process (ie, should I run the app? do I need to restart after install? run the app and close? etc) that will keep me from getting false negatives (ie thinking an app isn't causing the problem when it is)?
Update again: I'm working down in alphabetical order through the factory apps. However, after the most recent factory reset, it appears that my battery drain is back, and as long as the battery drain is there, the phone works normally. So, not looking good in terms of battery+functionality for me. Went through the 40ish apps that were on the phone stock--after the fresh reset, the phone is working, but the battery life is shot to **** all over again. Not sure what to make of all this, and now back to being frustrated with a 4 hour battery life from the phone that never sleeps. UGH
Update yet once more:
For kicks and giggles, tried unchecking the "Touchless Control" in settings, to see what effect that would have on my battery. But, reasoning that whatever wakelock was keeping my phone up all the time had to be persisting after it was needed, I guessed I needed to reboot to get rid of them. Booting up again, I'm back to battery life without audio/video/etc. Very confused here. Apparently it has nothing to do with the apps installed, period.

Facing the Same problem please someone tell me What should i do

Same problem! No audio call

Please help me I have this same problem. No audio, cant play video, nd mic isn't working.

Z5 issues after rooting/installing Xposed

I'm currently with the latest version. I rooted my Z5 about a month after buying it and some weeks later I installed Xposed on it. Since then I have experienced these problems:
- On the YouTube app I can't watch any videos after watching a certain quantity of them (I haven't done the experiments to know what that quantity is). The only solution is to restart the phone.
- Similar to the previous problem, the fingerprint scanner stops working after some uses. Or maybe it's after a certain time, since once I experimented using it continuously until it stopped working but I stopped at about 30 uses because it was still working. It says the hardware isn't working, or something like that. Again, the solution is to restart the phone.
- The last (maybe) problem is probably related to Xposed or root. When going to the settings and trying to see the apps section, it takes tooo long to load. I do have a big amount of apps, but I feel like it's just to much. The worst part is that when I directly go to an app's settings (without going through the phone's settings and all) it is very slow, like it was loading all apps again
So, do any of these problems have solutions? Or does it only happen to me?
Oh, and I need to address this:
Is there a way to hide the headphone notification? I hate it and hate the fact that Sony put it there just because yes and with no option to disable it.

You can do it with the xosed module GravityBox.

Laggy Pixel - almost impossible to make/receive phone calls

Hi all,
Pixel 1 after one of the latest updates turned into almost unusable piece of junk ;/
I do not know if this is OTA update issue or hardware fault, but phone must be restarted frequently, otherwise is almost impossible to make phone call - phone is laggy, screen doesn't respond properly, sometimes must hold power button for several seconds to force reboot, as it is not possible to reboot using the screen.
After reboot seems to work fine until someone is calling - when I answer, the caller cannot hear me and I must restart the phone again to make another try. Sometimes it work and I can talk over the phone, but mostly don't.
Phone never been rooted or anything, always updated with the latest OTA software.
I did factory reset - no change ;/
Is there anything I could try? I was thinking to try to go back to older software, but I'm not sure if this is software issue, as didn't found any other posts on this forum describing similar problems.
It is unusable anyway, so I will try anyhing.

Ive updated to latest ota on pixel 1 and had no problems so far. You could check the dialer app is set as default dialer and all permissions are granted and maybe clear the apps storage/cache, force stop it and re open it and see if that solves anything? Could also check background apps and running services in developing options to see if an app is banging out the memory causing it to lag?

if you already did factory reset then it must be a sign of motherboard is dying soon or bad nand chip. motherboard failing on pixel is very common but it happens to less than 1% of people. there are plent of threads on reddit/xda on this.

What's the status of your Pixel? Is the bootloader unlocked? Rooted? Did you have any such problems on the December udpate?

As mentioned - I did factory reset as I thought it may help cure the problems, but it didn't.
I have never unlocked bootloder and phone is not rooted. All standard here.
I have the latest update installed and same problems persist ;/
I'll try another factory reset today.

Is my phone on the way out??

Hi All,
I've had the phone about 8 months, UK model.
About 2 months ago, when scrolling in Wikipedia pages on Chrome browser, the display would alternate between normal and blue light (eye comfort). It still does occasionally.
From a few weeks ago, the keyboard sometimes take about 10s to appear.
A few days ago when on voice call from the phone other person can't hear me but I can them while voice call on Whatsapp is fine both ways. Restarting phone seems to solved it for now.
Then yesterday while trying to access settings from either the home screen or app drawer, it fails but you can see its attempting to as you see the settings screen momentarily then a message comes up saying settings failed to start several times and whether to restore by clearing history. Doing that doesn't work. The only way that I can is to touch and hold the settings icon till the search option comes up and then type the particular setting I want.
Before I do anything to fix this, are these symptoms an indication the phone is on the way to a complete breakdown? Would it be a software problem and I suppose the 1st step to fix is factory reset.
Has anyone experience this on their phone?

Unfortunately it's the Oppo software that causes these issues... We hope we can unlock the bootloader soon and flash custom roms to remedy these problems since Oppo are just incompetent.
Chrome colour shift is fixed by typing into your chrome address bar and type: "chrome://flags" then search "Dynamic Color Gamut" and set it to disabled (or it was enabled, I forget since I didn't have the issue myself)
Oppo uses the wrong microphone on third party apps like whatsapp, signal, instagram etc. and we have to wait for an update to fix that. (Issue has been posted here before)
The rest of the issues you described sound like some software instability caused by the Android 11 update. You should save your data and do a factory reset.
If the issues persist after the reset and you didn't install any dodgy apps or modified the software using adb then consider sending the phone in for repair.

OK thanks for replies. So factory reset then...

Touchscreen unresponsive until locking and unlocking

First Ill describe my situation
I have a redmi 9a with ArrowOS12.1 rooted, but Ive seen this issue described for many many devices.
This video ilustrates how the issue presents itself pretty well
this happens mostly when the phone is working hard, when I have 2 or three apps runing at the same time, specially with youtube, the weird part is the phone keeps playing the video and doing the other proceses as if there is no issue, and I can lock/unlock and the touchscreen will work again for a while (commonly here I close applications becasue if not the touchscreen will malfunction again.
this alwasy fixes itself when locking and unlocking the phone, my phone had this issue pretty much since I bought it new from the store, it was not refurbished, I did not return it because I thought the phone was just slow at the time
Ive been looking for solutions for a long time already, most threads say its a hardware issue, but that doesnt make sense, if it was, why would it fix itself when locking unlocking, It never happens on a clean ROM install, but it starts to happen after installing applications.
Ive tried a few things
First I installed a custom ROM, and rooted the device, I installed a magisk module to improve touchpad sensitivity (by weareravens) and the issue did seem to get better, but it was still there.
I tried to modify build.prop, but reading a little on what those modifications did I dont think those wouldve helped, Im a total n00b, but I dont think its an issue of the screen not detecting my finger, its like "the phone kills the touchscreen event" when it gets overwhelmed and cant deal with it.
Ive been trying stuff today and activated show taps, and yeah, the phone doesnt even detect the taps, but I still tried some more and got to this posible solution https://forum.xda-developers.com/t/touchscreen-issues.2875959/post-68018932. it actually worked, the thing is the phone now is slower than before, but it clearly worked.
My question
My question is, is there a better solution for this, Im limiting the procesor to half it is able to do, is there any way to give priority to touchpad ideally on system config files so it doesnt just kill that event but kills background apps?
