[Q] Vibrate/Haptic Feedback Randomly Stops Working (Evo 4G)

I am having a problem where all vibration/haptic feedback will just randomly stop working completely. Then a few hours (and sometimes days) later it will randomly start working again. It will keep working again for a few hours or maybe days, and then randomly stop again. There seems to be no pattern to it.
I have no idea what is causing this. Has anyone else experienced this, or does anyone have any idea how to fix it?
This is extremely frustrating as I am someone who never uses the ringer; I just always have my phone on vibrate.
I'm running the latest stable release of CM 7.1 for the Evo 4G, but I had this happen before on stock Sense as well.

I am having this same issue as well. It must be software related because the vibrate function works just fine when the phone rings. I am running CM 7.1 stable on an Evo 4G. I noticed the issue as well on CM 7.0.3.1 or whatever the latest stable build was on CM.

Does the phone ever always (or never) vibrate under a certain circumstance? i.e. incoming text, email, incoming/outgoing call, typing, etc.? Also, do you have any toggle widgets that could affect vibrate/ringer status?
I ask this because, and this may sound silly, it may be that you are modifying settings unknowingly. I've had that happen where I have my hands in my pockets and next thing I know I've accidentally got my Facebook up and running and typed half a book in the status field.
Again, I know that sounds silly but I ask because it's happened to me before.

That's fine, its an important clarification to make. But no, I am absolutely sure I have not changed any of the options unknowingly. As I said in the OP, ALL vibration/haptic feedback will cease to function entirely. I've often had it happen that in the middle of typing something, the haptic feedback for the keyboard will just go away. Immediately after this if I check the soft key buttons or test the vibration for notifications, none of these will produce any sort of vibration response either. Then randomly a few minutes, hours, or days later, all haptic feedback will just return. Its been an extremely strange and frustrating issue.

For me, when the vibration stops working, it stops working for everything, even when the phone rings. But that's what I can't figure out: if it is a software or hardware related issue. I was having this problem on stock Sense, and I figured if it was software related, perhaps flashing a new ROM (in my case, CM7), would fix it. However it hasn't, so I'm beginning to think if it is indeed a software issue, it must be a bug somewhere very deep within the code, otherwise it has to be a hardware issue. But if its a hardware issue, I can't figure out why it would randomly stop/start working like it does, and the thing is, most (75%) of the time, it is working. Its just the other 25% that annoys the hell out of me. That's why I thought I'd ask and see if anyone else had experienced it or found any solutions.

Its a CM7 thing I've noticed it on Xplod, Decks, and CM7 I don't really mind it cuz my ringers are loud as hell but yeah its pretty weird :shrugs:
Usually AOSP ROMs for some reason have that problem cuz on sense ROMs it never happens

I've never had that problem on CM and I've been using many different versions of it for a long time. I don't know if I am lucky or what but people complain about a lot of issues that are claimed to be CM issues....yet I've never had a single one of them.

Well I kinda had the same problem that he's run into on CM but I figured it out but I figured since he's had the problem on a sense ROM also then maybe its not the ROM but I jus went into everything that had the option to vibrate and turned them all on cuz I've flashed a couple ROMs and the vibration would be off I try not complain about anything about any ROM its a person hard work they've done for free I try to figure things out on my own as much as possible before I create a thread not bad talkin the OP but jus sayin you know?

I don't think that it's rom related. I've been having issues with my haptic feedback since I got the phone, even before rooting it. I think it's just a crappy vibrator. (If there's a better name than "vibrator", please someone tell me.)
I had vibration problems on my first Evo as well, it was never rooted. My second Evo was a HW004 and the haptic feedback was perfect - it was softer instead of the shock-like haptic feedback I've experienced with my 003s. My current and third Evo is also a 003, so I assumed it had something to do with the motor used in 003s.
I've just turned haptic feedback off. I thought I'd miss it, but I've gotten used to it. I still use have my phone set to vibrate for notifications and calls and I've seen fewer issues.
If you think you can go without, I'd suggest turning haptic feedback off. Otherwise, unroot and take it into Sprint. You may have more luck calling, because if you can't replicate the issue in front of them then they can't do much.

Yeah, its definitely not ROM related...I don't know if people aren't reading the posts, but I've said several times that this occasionally happened on stock Sense, both before and after rooting.
Dang. I didn't want to have to bring it in to get it fixed, but I guess that's what I'm gonna have to do if its a hardware problem...I was really hoping it was software related or if someone would know of a way to fix it so that I could avoid dealing with warranty services...I got suckered into the Best Buy warranty, and it turns out that even though they either give you a new or refurbished model, they make you turn yours in and wait 5-7 days for the replacement to come in instead of ordering the replacement and then doing a trade with you when it comes in. I already experienced it once before when my USB port broke... :/
Not being able to replicate the issue is my main concern since sometimes it works and sometimes it doesn't. Trying to get it to stop working at a time when I can actually run out to the store is gonna be a pain...And I really don't want to waste a trip to the Best Buy store only to have it start working again with me trying to tell the GeekSquad Agent, "I promise, I promise! It was broken just 5 minutes ago!!" I can't imagine how many of those they have to deal with....

[Q] No haptic feedback ("vibrate on touch") in Galaxy Nexus

Hi everyone,
I've looked for a solution all over the net, but seems like no one had this problem before (guess i'm a special girl...):
The vibrate feedback when touching the screen just stopped working, in spite of the settings under "settings -> sounds -> vibrate on touch".
It started after an update to AOKP rom - milestone 5 (based on ICS 4.0.4) + Franco kernel nightly r151, but effects all the other roms. Maybe one untouched system file damaged.
I've tried everything: restore from previous nandroid backup, another rom (CM9), another kernel, another launcher, I even wiped everything and flashed new and clean rom-stock from google developers' page. And yet - no vibrate feedback.
The wired thing is that the haptic feedback is working in few specific applications, like the build-in ICS keyboard and the dialer Dialer-One, so it probably not some hardware failure.
All this time there are five softkeys that still have haptic feedback: the buttons of the nav-bar, the button that opens the applications drawer and the google-search widget.
I've tried using "KickBack" instead, but it's too aggressive and very uncomfortable.
PLEASE, PLEASE - Help me!

Same thing happened to me. I had the exact same setup and the haptic feedback went away after I flashed the kernel. Since I've had lots of issues when trying custom kernels, I just restored a nandroid and went back to the kernel included with aokp.

Restore fixed my issue, so I'm not sure exactly what to tell you.

Some kernels have haptic adjustment, see pic for kernel does.
I'm running Franco 152 and mines fine.
I know trinity kernels lower it

I'm also using Franco kernel, but I don't think this is the problem because i've tried some other kernels and none of them fixed my haptic.

Hi TaliKa
I've just had this problem myself but it happens long after I flashed aokp m5 + franco r152 (too) so I'm not exactly sure what caused it. However after I went to clear my cache and dalvik cache, everything seems fine again.

Thanks guys, but as I wrote in the first msg, those actions didn't help.
Is there any pro here who can offer a profound solution that I didn't tried before?

Which system file responsible for the haptic feedback?

Guess I'll have to stuck without haptic feedback...

just wanted to say...exactly the same thing happened to me (started with aokp milestone 5 and vibration gone afterwards...)
im trying several things to get it back...i use it alot (at work and most of the time..its on vibrate)
hopefully we'll find a solution

Yeah this just happened to me too. It was working fine for awhile on AOKP and then all of a sudden it stopped. No idea what happened exactly. I tried whiping everything and restoring CM9 but that didn't work either. I thought maybe hardware but the phone vibrated on boot so it isn't that. Hopefully we find a fix...

im starting to believe its a hardware issue (well at least for me) i mean i dont even get a vibration upon booting or turning off the phone...and i even went back to full stock...same thing
maybe it might have been some software issue that led to the overburning of the motor(doubt that though)
what is weird though is that the same scenario happened to us so im lost...
maybe i should start talking to samsung for my replacement
meanwhile...im very open to suggestions that might help my case
hope we find something soon...u guys, does it vibrate at all?when u turn on ur phone?turn off? unlock ?

Yes, it vibrates at boot and also when using application with it's own vibrate settings, like "dialer one" for example.
Did you try using KickBack just to check the hardware?
if it's some hardware issue, maybe you can apply to your warranty supplier about that, just flash stock rom and relock your device before.

Good to know. I went ahead and flashed the base image and it restored vibration, then I rooted and flashed AOKP again. It worked for about that day and then this morning when I woke up the vibration is gone again. I'm almost positive it's AOKP's software. I'll test another ROM (Android Revolution) for a day and see if it happens again.

[Q] s3 stuttering/twitching

I have tried searching for this problem but I must be using the wrong terms... so sorry in advance if I missed a post that addressed this issue.
My sprint S3 does this twitchy/glitching thing on every touchwhiz based jellybean rom (does not do it on TW ICS ROMS) I have tried. It basically makes it nearly impossible to do sliding animations, IE it can actually get stuck and start flashing halfway between screens, or when pulling down the top menu, however you can open new programs just fine if you are already on the right screen for them. Luckily it does not do this all the time, but when it happens it keeps doing for 10 minutes or so and its annoying as hell.
I figured this must be a rare issue even though it effects both my wifes phone and mine, since I have never read anything about it, however I just got a new replacement phone and it does the exact same thing, even on dead stock TW JB ROM.
Oddly enough I discovered last night that if I turn on my screen filter app it stops completely, but it starts right back up when I turn off screen filter..... any ideas how to fix this?

Try grabbing cache clear from the play store and set it to run every 12 hours. It helped my phone a good bit.

Urgent and Serious issue with audio! HELP needed. please!

Guys, I have this one major issue with audio in my phone and its the rarest of the problems! The whole audio output stops completely. By completely, i mean even the receiver sound. completely dumb! cant hear anything if someone calls me. This has been occurring since a month or so. I am running on Cyanogenmod 11 M8. Even if i restart the phone its stays the same way. And all of sudden, randomly, the audio back again, working properly. when it goes dumb it stays like that for 5 6 hours. it happens quite often. this is throwing me off totally.
Device : Galaxy S3 SGH i747 - At&t
This problem happens:
1) when i am on call, suddenly it goes mute.
2) when the phone is kept idle for more than 3 4 hrs. So every morning its dumb when i wake up.
These are what I've tried and what I've found out:
1) I reverted back to stock 4.3 to check if its the problem with audio hardware. But in stock it worked perfectly and flawlessly. no issues there. SO its definitely got to do with cyanogenmod.
2) I flashed ktoonsez kernel on CM 11 M8, to check if its kernel problem. But its happening again. SO its not the problem with kernel.
3) I recently found out that if I wipe the cache from recovery, audio is back working. SO its definitely something in the cache thats messing with the audio. Some app may be.
this thread can be referred for more details on this issue:
http://forum.cyanogenmod.org/topic/81373-audio-stops-working-from-time-to-time/
and I dont know what else to do now. Ive tried uninstalling all the apps that access audio. But the problem still persists.
I really really need help fixing this one. PLEASE HELP.

I've had that issue a month or two ago but haven't seen it on the latest ROMs. I'm not sure what causes it but I would suggest you flash another ROM if CM messes up with your sound (or another version of CM).

Hi, Thanks for the response. I personally like CM and the extent of customization it offers. I actually dont mind switching cuz sound is bigger deal. Would you mind suggesting ROMs that are similar or comes closer to CM and also good at the same time? which ROM are you on?

Hey it got fixed in the latest nightly ( cm-11-20140721-NIGHTLY ). I had put it in cyanogenmod forum, I guess they read the issue and fixed it. Audio is perfectly fine now! Feels so great to use cyanogenmod again.
Thank you cyanogenmod!

I have this issue too but it doesn't have to do with the audio disappearing; it's simply gone from the get-go after clean flashing a ROM.
As you've said, stock FW and ROM works fine, but anything custom will just totally break it. Seems to be a very isolated issue with the phone itself, I've searched all over for people with the same problem but could never find anything.

Oh. It used to happen to me once or twice. No audio when I install CM, after it boots the first time. I think you should check the new nightly of 7/23. Looks like its fixed. They've fixed a number of audio issues over the last few nightlies. And I've always preferred CM over any other roms, so I've no idea about why it isn't working on other roms.

Thanks for the suggestion, I may as well give it a try since most everything else I've tried has had the same issue.
edit:
Clean flashed latest CM nightly, sound worked for around 2 minutes, then stopped when I plugged headphones in. Rebooted, got it to work via speakers again but then DSP manager force closed and left me without sound.
Rebooted into recovery, cleared cache, still no dice.
Going to try another clean flash to see if I can get sound to last a while longer.
edit 2: It seems to be screwed completely now, no sound after install + reboot.
Same logcat lines as in http://forum.xda-developers.com/galaxy-s3-att/help/audio-wide-custom-roms-t2825135

My device freezes in a black screen

Hey all!
This is happening to me for 2 months now, I was running official 12.1CM and now official 13CM
I tried to also use some stock based rom but im pretty sure it happened there too.
Whats happening to me is that randomly throughout the day my phone's screen turns black and I cant reboot it by any home button combination, only by getting out the battery.
When this happens the phone just totally freezes and I cant get it to respond or make a sound.
I don't think that the phone dies because sometimes when its freezes I can still see the notification led blinking.
Does anyone know why this might happen? or where can i copy some logs that might help you guys figure it out?
Thanks in advance!

sounds like you have the sleep of death issue? Personally I haven't been on CM roms much on my G3 so I haven't really encountered this issue but on my previous phone I've encountered this a few times on CM.
EDIT: Though it shouldn't happen on stock are you sure it happens on stock as well?

I have this issue as well using the Exodus rom. I never had it while using a stock rom, so I think this is a cyanogenmod issue (Exodus is a CM based rom in 5.1).

I have the exact same issue with my vs985. Seems to happen the most when viewing any sort of video, but I have had it happen at other times as well. Pretty dang annoying, probably 3-4 times a day. Using CM 13.0-20151217-nightly-vs985 but it started when I first flashed CM. Never had the issue on stock rooted rom.
