Random...haptic feedback?

My Evo, no matter what ROM or kernel I run, will give me a random "bump" every once in a while for no reason. Sometimes I'll feel it when I pick up the phone, sometimes it does it while I'm using it and right now, it's sitting on my desk, asleep, bumping every so often. It does this all day, with or without haptic feedback enabled or anything set to "Vibrate". Someone with the EVO Shift has a similar problem but I don't think it's as random as mine.

Do you have any apps (Tweetdeck/Facebook/etc) set to notify by vibrate but turned sound/notification icon off?

No sir, I ran a naked ROM setting up nothing and in airplane mode. It would still do it in no particular time frame. This thing is possessed lol

My phone has randomly done it a few times. Like i pick it up and my hand glides across the bottom pad and it never turns on, but then vibrates funky real quick. I never paid attention to any specific rom ro kernel though. It has happened maybe 3-4x before.

[Q] How to Change Screen Timeout...

...while on the phone? The screen goes black in a matter of seconds and isn't affected by the general timeout setting. This can be a real PITA while navigating a VRU system.

Have you tried going into settings/display/screen timeout?

That is the general timeout setting I was referring to, and it doesn't affect screen timeout while on the phone.

That's strange it shouldn't be timing out on you then. Maybe check the settings on the application your using and see if theres a reason it might be shutting off then.
i know when i had the mt4g and even my current G2x the display would turn off while talking on the phone then re-appear anytime i held it away from my head, probaly just the sensor.

Mine does this too.. If I am on a call, the screen turns off rather quickly. I need to be able to toggle the mute during conference calls and it is a real PITA to have to hit the power button first every time.

Pain in Le Tush!

This sounds like a really stupid solution but I have experienced the same issue before hand. What I realized was in many cases when I was going to touch the screen my hand was getting close to the sensor on top that shuts off the screen while on a call. You know like when you put it next to your face to ensure that you aren't pushing buttons. Not sure if that is it, but just speaking from personal experience.

Mine does this sometimes , it just did it on this xda app and i know it wasent 30 seconds yet. also sometimes it doesnt lock just comes right back on after i hit the button

This is what I figured out after 20 or so times hitting the power button while on the phone.
The screen automatically comes back on in 1-2 seconds when you pull the phone away from your ear. Once I realized this, I stopped fouling it up by turning the screen off and on again with the power button. It would be nice if this delay could be adjusted, but it seems to work alright as is.

There is nothing wrong worth any of your phones as far as I know it's not adjustable yet.your phone does this while making a call to prevent your face from making a three way call or accidentally hanging up on whoever your talking to. Some one can correct me if I'm wrong but that's what I've heard and read several times and my samsung captivate did the same thing.
If you pull the phone away from your face so that the sensor can pick up the change in ambient light, or what ever it is that it does your screen should come back on shortly.to be honest
I kind of wish it would react faster, but it's still pretty good.

[Q] Notification problem

So I've searched everywhere and I haven't seen anything for this issue. Even though all the settings are correct and i have vibrate checked in the messages app, my phone won't vibrate for notifications like text messages all the time. Sometimes it will vibrate and sometimes it won't. So my phone will be in my pocket and I'll check it 30 minutes later and see 3 or 4 texts but it never vibrated. I exchanged my phone and am having the same issues. Everything is stock. Has anyone had this problem?

the phone vibrates, it just does it too softly for you to feel it... that's the problem with light phones, the original epic 4g could cause an earthquake but that's because it was gigantic, I never felt the epic 4g touch, and this one I feel it at times...
Sent from my SPH-L900 using xda app-developers app

no it definitely doesn't vibrate. I've set it on the table and texted it and it'll vibrate on every 10th text or so. usually it'll just light up for the notification but it won't vibrate.

menu/settings/sound...........make sure sound and vibration are checked. that is the default for the entire phone even if vibration is enabled in messaging. also make sure your vibration intensity is all the way up.

Yes that's already been checked and vibration intensity is all the way up. The phone does vibrate on some texts, but not most, which is what the problem is.
I've noticed it'll vibrate normally when the screen is on and I get a text, but it won't when the screen is off?

I've definitely seen bugs in phones in which things like notification LEDs didn't work when the phone was in sleep mode. Whaddya know, I recall one of them being a Samsung (Intrepid). Granted it was years ago and Windows Mobile 6.5, but whoever was coding notification and power management back then wasn't fully aware of the point of "notifications".
Then again I just sent myself a test to the Note 2 while the screen was off... phone vibrated, screen turned on briefly (I hate that), blue light started blinking, heard my notification sound, and screen turned back off.
So there's something interfering with your phone's ability to wake up while it is trying to notify you. Have you done any power management modifications or installed anything designed to save battery power?

I haven't changed any power management settings or downloaded any apps designed to save power. I've tried factory resets several times. The phone will vibrate for texts but after about 30 minutes or so goes back to not vibrating. I've called samsung and taken it to the sprint store and no one can figure it out. I first thought the motions was causing te problems but it still doesn't vibrate when those are off. I'm completely out of ideas.
EDIT: I may have figured it out, if I turn on "Wake up in lock screen" in the settings in S Voice, the phone stops vibrating on texts. When I turn it off, the phone vibrates again. Toggled it on and off and the changes were immediate. Does anyone else have this problem??

Doubletap2wake randomly/periodically does not work?

Why does doubletap2wake randomly stop working? It has nothing to do with phone being idle, still doesn't work after movement, have to unlock to get it back to work again.
Is this because of deep sleep or power saving mode enabled in sense?
Is my M8 defective - is this a hardware issue?
Running ARHD and ElementalX 0.18. Had the same issue on stock kernel - can't remember if I had it on stock ROM but someone else told me he had the issue too on all ROMs.

This is a stupid question, but I have to ask: Are you sure that you are holding the phone vertically so that it is in portrait mode?

sometimes i notice that the double tap to wake won't work because i have some stuff on my screen or something that registers as a screen press. i'll have to wipe my screen down.

It's all in the finger action. One to wake the sensor at any corner of the phone, then 2 deliberate taps, not 2 quick taps, on the bottom half of the screen.

I have this exact problem. At least 1-2 times a day, motion gestures will stop working and I have to use the power button to turn the screen on. I have tried everything when this happens (making certain phone is in portrait mode and held straight up, shaking the phone, tapping the corner of the phone before doing the gesture, etc.). I am well aware that the phone has to be moved before doing the gestures. This is my second HTC One M8 from T-Mobile. The first had scratches all over the back out of the box so I exchanged it. I don't recall this ever happening with the first phone. Maybe some app is messing things up? Could this be a hardware issue? I'm hoping it's a software issue.

Make sure you don't accidentally swipe up while the screen is off as this seems to lock the gestures out.

Really? I haven't heard that being mentioned before. It's possible I accidentally swipe up just a bit when I'm trying to DT2W. Has anyone else mentioned about accidentally swiping up while the screen is off and it locking the gestures out here on XDA?
mhajii210

I've noticed this as well, but only with the double tap(swipe up or to the side always works). I would say mine only does it about 2% of the time though so I haven't been too concerned about it.

Hi guys. I just wanted to report that I updated to the latest stock 4.4.4 OTA 4 days ago. I no longer have any problems with the gestures randomly not working (including DT2W of course). I'm a happy camper =D

Also make sure when you pick it up the meat of your thumb or other part of your hand is not touching the screen. I've caught myself doing that a few times.

Your title pretty much sounds like it is referring to my brother.

I am having this problem too with or without the dot view cover
Sometimes it does't wake up... it's like its in deep sleep like the OP is saying
Any help

two large speakers and some gabba techno should do it
Lol think the phone needs to be at a slight angle when using double tap. i have noticed before when my phone is flat on my desk at work and the screen has been off for a while, its seems to be in deep sleep mode, however when i pick it up, double tap works

It happens to me maybe a couple times a week. I reboot, fixed.
Poop happens is my explanation.
I wouldn't be very concerned. Things get screwy in the system every now and then, that's all.

Whenever it does that, I just rub my finger across the proximity sensor back and forth a few times and then try the double tap again and that always works.

Difficult to turn on screen in dark

Has anyone else noticed that when in a dark area, pressing the main button will turn on the screen but it will then automatically and immidiately turn off?
Several times I've gotten into a battle with the phone only to lose, turning it on and it turns off, then turning it on again and so on...
To compound the issue, in these situations it seems that double tap is signifigantly less responsive to activate the screen as well.
I'm pretty sure this phone is using some sort of facial recognition, it has smart stay doesnt it? I think it has gravity/accelerometer to turn on the screen when you pull it out of your pocket. In the back of my mind I'm thinking that since it cant see me it is shutting off but this doesnt seem consistent...
I'm running stock rom, rooted with twrp. Any ideas?

I have not experienced that. Did your G3 do that out of the box?
Sent from my LG-D851 using Tapatalk

Never heard of it. Screen is set to auto off in 30 seconds. Change it to 2 min and you should be good. If u running without a case then maybe the hand is touching the edges of screen this will also shut screen off in double tap.
BAD ASS G3

I didn't notice it until the last week or so. but I kind of feel like that was because I hadn't used the phone that much up until then. I didn't make any major changes to the phone immediately before I started noticing it either, I had already had it rooted for about a week. I feel like the stock rom does have some glitches to it.

The G3 does have a "smart screen" feature that detects your face (Settings > Display). Disable that and see if it helps.

I've not run into this in the dark but have when I try and use my arm band holder when running. The holder covers the ambient light sensor so the phone thinks it was accidentally turned on like in a pocket and shuts right off. Super annoying.

Noticed similar behavior when the phone is in my bike mount at night. Basically it's acting like the proximity sensor is covered. In my bike mount's case, it is covered by a clear screen cover, but normally that doesn't trigger the proximity sensor. But when it's very dark out (not under a street light etc.), it seems to think it's blocked and turns itself off. Annoying.

Tried but remains the same... This was the only thread I found concerning this.

Ive had this issue too investigating now

Had that issue when I was using the lock screen face unlock. In the dark it didn't see my face and then it shut off. Setting is in lock screen section

Lol.

I have the same issue EVERY night. Why is that? It's very annoying

Same issue here
it seemed to resolve itself when I factory reset my phone
but after I got my apps reinstalled from my google backup it started again
so it seems like it's a software issue - not sure to which app it is related to
let me know if you find a fix - this is quite annoying

Me too. I've been facing this issue at night, when it's very dark.
Me and my buddy were in the car during a roadtrip and it was very dark, I mean like: No lights outside, no lights inside the car, the double tap feature didn't even work to begin with and whenever I tried to use the "Power Button" It would come on and then suddenly 'boom' Turn off, now this would happen a few times until it stays on. Weird...

I just experienced this myself, first time I've seen it happen in the 30 + G5's that I've sold. If it's in the dark it just doesn't turn on at all. I hope LG is fixing this. I'm about to Factory Reset it right now and hope for the best! Someone else mentioned that this is the only forum that is disccusing this issue. It must be a very few that are effected. I'm testing another one as we speak.

Has this issue been resolved? My friend's G3 also has this issue. Day time no problem. When it is dark the screen wont' stay on.

Same problem, no fix yet
Same problem here - Pointing it at any light and pressing the power button will turn it on. (As will plugging it into power). Tried tinkering with all sorts of settings (face recognition/auto dimming feature/etc) nothing worked. Tried factory reset, that didn't work either.
My issue started after i had my screen replaced (by a shady shop) who probably didn't do a good job of packing it back together....I'm going to see if I can have someone open it up and clean it out a bit..

I have the same issue on my G3. Even if you're under the covers in bed, the thing doesn't turn on until it gets light. It basically doesn't turn on in the dark through double tap and actually not even with the power button. It could become a safety hazard for someone in an emergency situation.
