Bug: bottom speaker not working until reboot - One (M8) Q&A, Help & Troubleshooting

I sometimes experience this. The bottom speaker stops working until I reboot the phone. I am investigating to find a correlation with some apps I use, yet this should not happen. Anybody else experiencing this?

Is the phone modded or stock? If modded, what custom ROM? Did you do a clean install?

Stock Sense rooted (unlocked bootloader + installed SuperSU). No other mods except for swipe to sleep.
EDIT: I say the bottom speaker stays silent "until I reboot the phone", but actually I reboot it as soon as I notice this, maybe if I waited some more time the problem would disappear without a reboot. I believe this only happened to me twice or three times at most so far.

Confirmed using Chrome
I encountered this issue and was able to narrow it down to an issue with Chrome(34.0.1847.114).
After visiting certain webpages I noticed the following issues:
1. When adjusting the volume the device shows that I am adjusting the “In-Call” volume.
2. No audio comes out of the bottom speaker.
3. The top speaker level is very low.
4. Wired headset will play at the previous level and it cannot be adjusted.
Here is a site that you can try that will put the device in this mode 100%: sci2.tv Go to the site, select home and you will notice all of the symptoms listed above. Go back to Chrome and close that page and the issues will clear up. Opening this link with other browsers does not create this issue. It also happens on the GS5.

Chrome 35.0.1916.122 fixes this problem.

4.2.1 bugs on GNex

I hope there is no similar thread on this yet and I request to all to add bugs here
my device: GSM international yakju-rooted
bugs:
1. clear recent apps in landscape mode, then switch to portrait mode and the cleared recent apps are BACK!!....and vice versa!!
2. Did OTA update with Bluetooth on and cannot switch off Bluetooth now with devices paired. Bluetooth switches back on automatically as soon as I try to switch it off. Correct me if this is a change in 4.2.1 or if this is indeed a bug.
Other complaints
1. apps on lockscreen widgets starting up randomly
2. 3 sec lag to start daydream and camera app
3. butter gone
4. laggy
luckily no random reboots and broken Bluetooth as others have reported on my device yet. I am not happy Google.
1. doesn't happen with me
2. can't test that (no bluetooth accessories)
Others:
1. lockscreen needs improvement (like clock widget auto resizing itself to full screen when swiping through screens)
2. my camera app starts in less than 2 seconds
3. 4.2 is a little heavier than 4.1.2 but still buttery compared to other high end phones
4. not on my phone
Something which happens to me when creating events on calendar... If i manually type in the end time of the event and the minutes are 59 (e.g. setting the end time to 22:59) when i press okay the time goes back one hour (e.g. 22:59 becomes 21:59). Anyone else?
I have none of the issues any of you have specified.

I got the same Recent App bug, which I didn't notice before!
But overall it is running smoothly. Did you try factory reset or flashing stock image?

* I listen to podcasts via Bluetooth car audio during my drive to and from work. Ever since 4.2, I get frequent Bluetooth disconnects while I am listening to audio. This never happened before 4.2. Unfortunately, 4.2.1 did not fix it.
* When third party apps such as Locale or Tasker turn WiFi on, it will not connect to any access points in range. However if I turn WiFi on via the WiFi settings, it connects immediately.
* Car mode is broken in 4.2 and 4.2.1. A "car home" app used to be able to invoke a mode where the home button would return you to the car app instead of the desktop. Now, the home button drops you to the desktop and crashes the launcher (Android's desktop process).
* Overall, much more lag and delays. Looks like 4.2.x is optimized for the Nexus 4 and its 2GB of RAM. 4.1.2 seemed perfect -- too bad we only had it for less than a month.
Well, my screen shuts off at random.. I can still press stuff, but it's totally black!! I have to put the battery and restart

I cannot use my BT headset, it disconnects when screen is off.
Camera is very very laggy.
Wipe phone and flash complete stock image!
I have none of these bugs! Bluetooth works like a charm.
Stock browser omnibox issue. When I open bookmarks and links from 3rd party appss, it's all good.
But when I try to type a search or url, the adress bar freezes and stays frozen on the screen. Rotate the screen and it becomes a black empty wasted space.
Is it a bug in in 4.2/4.2.1 or is it my phone?

Firstly, It sounds bit too much to do a complete wipe and re-flash or a factory reset for just a dot.dot update.
Also, I have been reading that for some wipe and re-flash did not fix the Bluetooth issue. Also, a just a factory reset after OTA hasn't worked for all.
Can we please have confirmation here that a the factory reset thingy works so that all of us having issues can give it a shot?
In case we should wipe and re-flash, can it be done in the following way?
1. full backup system (in my case using titanium backup)
2. factory reset
3. copy the relevant image , yakju 4.2 in my case, into memory and flash zip using cwm recovery (6.0.1.5 in my case). then flash 4.2.1 similarly.
4. restore root.
5. system data/apps restore
please let us know.
International Yakju here and I've get the most annoying out of the problems. Random soft restarts. I've done a soft reset and it didn't help. I'm getting really pissed at this. Thinking of rolling back to 4.1.x
I havent tested bluetooth but I have random errors, sometimes when phone is locked It vibrates, I unlock it and it is asking with wich program I want to open, I choose gmail and it attaches a bug report, a .txt file with 4mb and a screenshot tottaly black.
weird. 4.2.1 yakju

I agree with the 3rd and 4th points. Camera app is quite different from ISC 4.0 and Jelly Bean 4.1, both icons are rotating while the phone is rotated. However, Jelly Bean 4.2's icon, instead of rotating, they shift the position while the phone is put as horizontally. I hope these will be fixed in the near update.

I got the same bug on both my galaxy nexus and nexus 7. For those who said that they don't have this bug, did you leave at least one app on and rotate the screen while having the recent apps menu open? Try again.

Can I turn off updates
OTA update to 4.2, totally stuffed my setup, flashed 4.2.1, no difference, have now flashed stock 4.1.2. to make the phone work as it should do.
Problem 1: The signal strength meter vanished on my car screen, no indication that bluetooth had connected.
Problem 2: The speaker, as I am sure we are all aware, is rubbish. I am using the pucker car mount and have a small speaker system set up and hooked into this so that I can hear warnings from CamerAlert. The phone connects over bluetooth but the CamerAlert warnings are directed out of the device speaker and go via the car mount to the speaker system - works a treat. With 4.2 this totally disappears and I get half a warning from the device speaker itself.
Having gone to 4.2 and back I can vouch for the fact that it is the update that is wrong.It will take me another day to get the 'phone back as I want it and I will then do a full backup. Thanks a bunch Google for, really professional update.
All I want now is for the 'phone to stop nagging me to update, anyone know how to turn off updates ??
my phone freeze after taking a picture today, so weird it didn't happen before and i need to pull out the battery in order to restart the device because the power button not give a respond.. so sad.. in 4.1.x everything is good.. for the first time on my gnex i need to pull out the battery twice today.. huh!!
Wow. I was very pissed of with the overall lagginess of 4.2/4.2.1 update, but I thought I might wait and hopefully Google will fix that. But then I noticed just how ofter the stock launcher crashes (leaks from RAM anyways). 5-10 times in an hour after using heavy apps like Chrome, Pocket, Facebook etc I press home button and I get and empty wallpaper. WTF? How is this even possible for a stock app?. And then there are things I've mentioned in other similar 4.2-reated threads like camera animation that lags and music widget that stops responding and keeps playing after headphones are unplugged...Gosh, that's the worst update (for me at least) ever. And now I noticed that recent apps bug. It does exist. Awesome.

Bugs on stock AT&T firmware (4.1.1)

I searched the AT&T Galaxy S III General forum and saw no other posts similar. Essentially, I was wondering if anyone had experienced other bugs in the stock firmware. I am not rooted and have not modified my phone's software from stock.
There are two bugs I currently have seen. One I can and will provide screenshots of. This is where during the lockscreen the formatting will be incorrect, such that the last number on the time will be small and the charging text appears on the same line. Also note that the lockscreen shortcuts at the bottom are spaced oddly. I always have five icons, yet sometimes only 3 or 4 show spaced unevenly. I can reproduce this by watching Netflix and while a video is playing, I lock the screen. When I first unlock it, this will happen. This will fix itself if I relock the screen and wake the device again.
The second bug is in the messaging app. Sometimes when my device falls asleep by itself while I have the keyboard up and active on a thread, and I wake it, the keyboard is unusable. I can click on the message block to bring up the keyboard, but all of my keystrokes are not entered into the message block. I have to back out of the keyboard and thread, to the thread list, then go back to the thread. My previous keystrokes are still not showing, but the keyboard will then work.
Anyone else noticed any bugs?
I'm fine on my phone

I've had the second bug happen with the keyboard maybe a handful of times since I got the phone but definitely not a regular occurrence.
I wouldnt worry too much about it but if it bothers you that bad just try a factory reset.

I've only experienced this issue that you describe. I've gotten used to it, so I'm now indifferent towards it.
I've had issues with the battery life however and how the actual "percentage" is being reported, but I think that it's just Jelly Bean that is causing the issue when my device is restored to stock setup as opposed to running ICS. Sometimes, my phone gets really warm overnight (and I can assure you that nothing is running in the background). Looking at the battery graph, I see a sharp drop within the space of about 20 minutes. This causes the back cover of my phone to be discolored. My i747 is only 5 weeks old and I'm the original owner.
phone minimizes
I have an issue where my phone screen turns off when I'm it for a while (typically at work I use a wired headset). When I wake the phone up and swipe on the lock screen, the phone shows the phone "app" for a second then it jumps to the home screen (as if I hit the home button). Typically I'm unlocking the phone so I can either hit a number on the phone (like, press 1 for English) or I'm wanting to hang up. So I have to go back into the phone application to do either task.
ICS didn't do that to me.
Me and a few others have experienced a bug where the external sd unmounts itself at random. Mostly when the screen goes to sleep. For one freezing the MTP application with tibu solved his sd problem but by doing that you cant mount your phone to a pc. As far me nothing has helped yet. My external sd just unmounts at random and I have to remove it and put it back several times to get it to work again and sometimes and I have to format it in the pc to get it to work again. This has happened to a a lot of tmobile users. I never noticed this problem on ics so im assuming its a jb problem. Its not a micro sd card being bad because it does it with my other cards to and one is a very expensive Samsung card..

I think this has happened to me once or twice. But I guess with the scarcity it's happened I thought I was bumping the back button or home button with my face, i.e. a failure of the proximity sensor to correctly detect my face.
I just started noticing the Keyboard Messaging bug myself. Wasn't sure why it was happening.
I just remembered (or refreshed my memory since my phone just started doing it) that whether or not TalkBack is off or on, my phone needs to tell me which number screen I am whenever I slide my finger across the dots at the bottom of the home screen or the app drawer. Is this a different setting I am missing or is this another bug?
I have had the messaging bug occur a couple of times. No biggee to me considering it has only happened twice in a month's time. I have seen other phones with much more persistent and annoying bugs and by comparison, this is nothing.
no problems here... i like it a lot now
Problem on Stock/root
Hey, not sure if this is the right place for this post, but my GS3 is on stock jelly bean and rooted. For some reason I am not receiving incoming calls. I tried calling my phone from gmail and the phone rings, but nothing happens on my phone. Any ideas as to why this is

I'm not sure if this is the right place either, since this is generally non-rooted, although the topic doesn't specify that I suppose.
However, I would venture a guess that you may need to wipe your data and cache. Sounds like a default app issue to me.
If I use bluetooth headphones on my walk to work, then plug in wired headphones at work, the audio plays out of the speaker.
It's really annoying because it happens every morning (as it's too early for me to remember things like that) and blasts my podcasts to my coworkers. Removing the wired headphones and reinserting fixes the issue.

Actually, I've had a similar issue. I use Google Play Music (as a carry-over from my Nexus S). When the first song of the playlist would finish (using the headphone jack to play through my car stereo), the second song would start on the phone speaker.
It doesn't seem to happen anymore, but it did directly after the JellyBean update.
PIN Lock Instantly with power button
I am upset that the "Lock Instantly with Power Key" option missing from 4.1.1. I have been searching for a fix, but I must be the only one annoyed by this, or I'm bad at searching.
...
I have a pin lock but am used to a 15 min delay before I need to enter the pin, and being able to push power to shut the screen off at will. That is no longer an option as it always will lock to the PIN screen if the power button is pushed. It is very annoying to me.
Another bug is the Keyboard defaulting Samsung Keyboard on reboot. Every time I restart, I have to go back into settings to select Swiftkey.

Touch screen problem

Weird this. I sometimes find that the 'dock' area of the screen will not respond to new touches. Therefore I can't open the phone or the app drawer etc. Odd thing is that I can drag icons from elsewhere over the area which makes me think this is more a software issue than a hardware one. If I open Chrome links can't be opened if they are in the affected area. It's just weird.
Some times this requires a reboot to clear but other times it appears to clear by itself. From my observations it seems to start after using the camera app.
Any ideas? Could this still be down to a defective device?
Matt.
I experienced the exact same thing. Everything else works normal though. It happens after using the Camera app and goes away after I clear the app from the multitasking window (which I have to do app by app since also "Clear all" can't be tapped). I just hope its a software bug that can be fixed by an update.
Clearing running apps doesn't sort the problem on mine. Your problem certainly sounds very similar though especially given the connection with the camera app in your case as well. Tried a factory reset and the problem persists but it is very random and difficult to reproduce. Still not 100% sure it's not some sort of hardware fault as I can't really see any touch screen related problems being reported on the web and this one is very irritating.
I experienced this once - also after having the camera. I rebooted and haven't experienced it again.
I have the same problem where my touch screen doesnt respond in the corners sometimes. Really abnoxious when playing games and then i just lose because of this. I send my phone to HTC and i waited 20 days to get my phone back with the same problem as before. First i downloaded a touch screen test app, and there it didnt show any response in the corners but another touch screen test app registered every touch.
I have the same problem. Seems to be caused by either the camera or the photos app. Closing them doesn't help here, but a reboot does. It's something that started happening recently so I hope an update of some sort will fix this.
Very annoying... If anyone has found a permanent solution I hope they'll share it here.

Yes it is a software issue. U just need to revert the photos app back to the factory version. This can be done by going into settings >apps >photos app and the click on uninstall updates. Then reboot your device and the problem should be gone. Try it out and tell us if it works for u as well.

Notification bar pull down stutter after unlocking phone

I searched forum for similiar issues but could not found anything(though there are some reddit topics).
When I wake the phone with power button or fingerprint sensor, and try to pull down notification bar, there is a stutter/lag lasts 1-2 seconds. Lets say you pull up for app drawer there is nothing but pull down and there it is.
Also wallpaper seems to affect it a little bit but it might be a placebo effect as it still stutters(light the way wallpaper seems to solve it a little bit.).
It started after Android 10 update and I even tried to clean flashing whole rom but result is same and I do not have any UI altering apps.
It seems like a slow wake up issue and may be playing with sleep frequencies might solve it but I did not root so it is not a option for me.
Is anyone else facing this ? Vanilla or custom roms/kernels ?
Yep, I have the same issue. It's pretty annoying, but I did get it to stop, for me at least it seems the new gesture navigation is causing this because I can't get it to stutter while using the 2 or 3 button navigation methods. I've had this happening since I updated to Android 10 (stable release, not beta) but after a while it just fixed itself, unfortunately my phone ran out of battery yesterday and today after I booted it up it came back to haunt me :/
Alright I got it to stop, disabling both "New notification" and "Double-tap to check phone" did it for me. Hopefully this helps.

I have exactly the same issue on my Pixel 2XL, manage to fix it by disabling Google Feed on the left of the main home screen. Try it let me know if it works.
Update 1: disabling google feed doesn't work. I try to switch back to 3 button navigation and the issue gone.
I do not know how but now it is smooth everytime I try to wake phone and double tap+alwayson display is enabled. Also I tried all wallpapers and it works without any stutter.
Probably monthly updates fixed it, idk.

Ring, Notification, & Alarm sounds are silent/don't work (but Media & Call sounds DO work)

Hi all,
Hoping someone brighter than me can figure this sound issue out.
THE PROBLEM:
Half of my sounds don't work, rendering my phone useless in the current state. As the title says, Ring, Notification, & Alarm sounds do not work. You know, as in the important stuff that makes your phone, a phone? And makes you wake up in the morning? None of these respective sliders under Sound & Vibration settings make any noise when making adjustments. By contrast, my Media and Call volume sliders DO make noise when adjusting. And sure enough, once on a phone call, I hear things just fine (Call). And YouTube, Spotify, et al. (Media) also work just fine.
Because some sounds work but others don't, this has to be a software issue, right? This would be easy if it was hardware and 0% of sounds worked, but nope, it's partial.
BACKGROUND:
This pixel 3 xl is relatively new to me, but has ran A10 and A11 with a few different ROMs with 100% of sound working flawlessly. But out of nowhere, sounds suddenly stopped working correctly as described above. And it didn't occur immediately or shortly after a new rom flash or update or anything like that. Just stopped working, months into a well-running ROM.
I've tried a couple different ROMs now to fix the issue from a completely clean install (/format data + flash latest google factory image as 1st step) but none have fixed the issue. Specifically, pixeldust (A11) and evolutionX (A11) were my latest troubleshooting attempts with no avail. Pixeldust was the ROM that was formerly working and then after months of 100% sounds working, suddenly stopped.
It's odd that searching throughout the ROM threads that no one else seems to be having this issue. Again, this would be easy if it was a hardware failure. But that doesn't explain how it works for Youtube/Spotify but not for other things, so it has to be software.... I think?
I figured I'd start a thread here rather than start posting in each and every ROM I've tried to troubleshoot this. Thank you!
This might not be relevant because I'm using stock Android on a Pixel 4a but my notifications have gone silent and this report was the only similar search result I found. I tried changing the notification tone and none of them played a short snippet so I'm wondering if the problem is there.
I have not found a solution for this issue.
One thing I noticed recently is that when I'm on a call using the regular "earpiece" or whatever it's called (which works fine), if I switch to speaker phone, I can't hear anything. I have to switch back to the non-speaker ear mode and I can hear the call again.

I think I may have finally found the solution!! Sometimes it's the simple things in life that work, rather than reflashing a billion different ways that finally gets things working again.
In this case, I simply cleared the cache and storage for the 'Sounds' apps under Settings -> Apps & notifications -> See all apps -> Click 3 dots in upper right corner -> Show system. Then, I deleted cache and storage for TWO apps, both called 'Sounds' with 2 different icons. I'm not sure which is the system app and which is not nor do I know if clearing only one of them was necessary, but this is what has worked for me and has survived several restarts thus far. Good luck!
