Wifi issues - maybe TW related

Ever since I installed the Wifi based TW ROM I have had issues with the wifi stopping. The issue continues with the official rom (with root and deoxed). It is set to be on in software but says disconnected. If I reboot device it works fine again.
Anyone else have this issue? I am very close to going back to stock even though I like the new way of doing notifications.

Same problem here. Simple way to solve it to enable and disable Airplane Mode... But yeah.. its really annoying. So any fix would be very helpful.

I've had the same problem recently. Did either of you install the free wifi server app that the Amazon store offered a day or two ago? That's when it seemed to start so I just removed it so see if that fixes my issue... here's hoping!

Same problem here, but it just started the day before yesterday. I've had Touchwiz since a day or two after I bought the device (almost two weeks). Hadn't thought to toggle airplane mode, thanks for that tip. Beats power cycling every morning.

I had similar issue with the stock Galaxy rom. Since the TouchWhiz update however, it has been running extremely well.

So after uninstalling the WiFi File Explorer Pro my WiFi has worked fine without any connection issues. Just like before and after TW. I also had a weird issue that wouldn't recognize finger presses on the lockscreen after waking up once every 10 to 20 times.
If you installed this app or something similar it might be worth a shot to remove it.

[Q] Nexus 7 screen turning itself on?

Hi all,
I'm experiencing an issue on my stock 4.1.1 Nexus 7. The screen seems to be turning itself on randomly. It normally turns off again but may toggle on/off quite a few times. Then it seems to go for a while whitout turning on. Bit odd.
Anyone else experienced this or have any thoughts on a reason for it?
Thanks

Same problem here, except with a Samsung Galaxy Nexus.
I just updated to 4.1.1 today and this is the first time I've seen it happen. Was previously on 4.02 without issues.

I have had the same problem. It seems to happen in the evening and I wondered whether the case was causing it to overheat. Seems to be OK when I take it out of the case. I phoned Google and was told that it hadn't happened before. I will contact them again if it doesn't get any better.
Sorry. Misread the post. Mine goes to sleep, not turns on

Same here but mine is not exactly stock.
I have installed Apex Launcher plus numerous apps. I thought maybe it was the launcher doing it. But at this point... I have no idea. Just noticed it tonight coming on and then going off within 1 sec. but its random. it may do it once within an hour, or it may do it up to 5 times within a min... then go several minutes completely black screen. Crazy stuff. I thought maybe it was getting a message at first but then realized I had the WiFi off on my phone so it was dead to any incoming messages/wifi. I am really curious as to what is causing it and will be following this post as well as others quite frequent. Also.... the latest app that I have downloaded was OSMOS HD. it wasn't waking then sleeping before that app... just my 2 cents.

Hi Qbensis,
By stock, I just mean not rooted and not running any custom firmware. I had various apps and the like installed.
I have actually since rooted my N7 and installed a few custom ROMs and since then have not seen the issue at all. If you want to stay stock, I assume the issue will be fixed in the next update

I have seen this a few times. Middle of the night I look over and the screen is on then off. I check the power usage overnight and I see little blips of screen on when looking at the graph. Not sure whats causing it (I figure a app).

Same Problem over here, any solutions???

I'm on stock 4.1.2 and having the same problem, not rooted. Creeped me out in the middle of the night when it goes on and off.

N7 Random Turn On
Same here on 4.2.1. I carry in front pocket all the time with screen facing leg and feel heat when it happens. Has even done it when in Power Off mode and still does it. I thought that would prevent it for sure. Very irritating and drains battery. We Winter in 55+ community and drive around in golf carts. I am starting to wonder if WiFi spots trigger it. Will continue to track behavior and search other forums. Curious that there have not been any solid suggestions or solutions.

Happens to my rooted but stock 4.2.1. It happens randomly when I recharge using a battery pack (4AA) as opposed to charging using regular AC. It's annoying as heck! I don't know how to get this fixed!

I've been getting this on both SmoothROM and raspbeanjelly, and it's very irritating.
It has to be an app that is causing this. I initially thought perhaps it was GPS Status, because I caught it in the notification bar a few times when the screen turned on.
My device definitely isn't hot when it happens.
I'm suspecting the Email app, Maps, or Facebook.
EDIT - not any of them either. I'll test Beautiful Widgets next.

Okay guys, try this.

I'd been suffering from this for weeks, factory reset, reinstalled and changed out ROMs, installed apps one by one over the course of several days to keep an eye on what might be triggering it etc. Nothing worked for more than 2-3 days at most, and the issue always came back in one way or another.
It was causing me to have to turn the Nexus off when not in use because it would be draining battery (15-20% overnight compared to 2-3% when the issue wasn't present).
Then I stumbled upon that guide and using Gemini I disabled Maps from auto-running, turned off Latitude, and so far so good.
If it works for you too, be sure to hit thanks on Karpfenhai's post!

I was having this same problem on my Nexus 7 running stock 4.2.2 rooted with SuperSU. Finally tracked it down to having installed BetterBatteryStats and for some reason, I had not granted it perpetual root. It was causing the device to wake and turn the display on for random times (up to 13 hours, which killed the battery), not always showing the SU request dialogue. I granted perpetual SU privilege to BetterBatteryStats and problem went away.

Try taking out the battery and clean out the USB port with a toothpick. This worked for me. All the dust that accumulates in the post can cause the phone to think it's charging.

[Q] 4.1.2 Issues?

I've had my Nexus 7 since July and I've been completely satisfied with it. Once I got the 4.1.2 update some strange things have been happening and I'm trying to pin down the reasons since it seems to be a software issue and not a hardware one. The first event happened when I was trying a Live Wall Paper, Oceans HD. After setting the LWP and using it for a few minutes the next time I picked the tablet up and tried turning it on I noticed it had reset. No problem, except after the splash screen everything would go dark again and the power button didn't seem to work at all unless I waited for a while, and tried long pressing it and rebooting the device. After a few reboots of this the screen began to behave weirdly, sort of looking as it there was a problem with the video driver since it looked like a an old TV screen with static. I thought the video hardware was toast and was relived the next day when I tried to reboot again that the tablet rebooted to the default WP. No problems after that. I contacted the maker of the LWP thinking that was the problem. However, after trying out another LWP from another maker, the same thing happened after a few days of use. Jumped through the same hoops and got the WP changed to a static one. I went online and read through a few forums to see if anyone had the same problems but was not bale to find the same issue. I read something about the auto brightness and turned my auto brightness off to see if that works. What do you guys think about this? I use the tablet a lot and for professional purposes often. I cannot afford to have it go bonkers during a presentation.

Are you stock or rooted? I'd re-download a stock 4.1.2 ROM and re-flash if your rooted. Regardless I'd try to redo the 4.1.2 update. Or go back to 4.1.1 see if the problem persists, if not try the update again.

It's the stock ROM. I think I know what the problem is. It appears the contacts of the battery may be loose, or that the battery's charge may be draining very quickly, since, after the tablet goes out, after waiting some time, I plug it back in and it reveals the charge to be 0. I know for a fact that it isn't 0, but this reveals the battery either was discharged or the contacts are loose. It is also charging up quite slowly. I'm beginning to think it is an electrical problem.

[Q] Delay for screen wake

Hi, one morning i woke up and my nexus 7 had a major delay when pressing the power button to turn the screen on. It is constantly taking 3-4 secs for it to wake. I have tried turning off currents but that has no effect, nor does a factory reset. Just so happens the first time it happened was after charging, i know there have been issues with charging bit not sure if this is the cause. Any help would be much appreciated.

I know it's a bit late to reply, but I just got my tab and after charging it to 100%, this started happening...
Hopefully now that I've uninstalled G+ and Currents (and rebooted), it'll stop...
Just erase any app you don't need (especially the stock ones) and see if that helps... I mostly blame Currents and GPlus...
I see that's on the 4.2.2 update, and it's also happening on custom ROMs based on it (PAC, CM, etc.)...

I encountered this too. screen rotate seems to be the culprit for mine

I sometimes encounter this also. But the thing that really annoys me is the slow auto-rotate. I decided to disable auto rotate and just turn it on when I need it. Accidentally, it seems to have also fixed this delay. It seems like the auto rotate is causing delay to the display of lockscreen since the lockscreen also rotates.

Could try raising your minimum frequency, it fixed my issues.
Nexus 7

intermittent serious UI-feedback lag

Most of the time, my Note 7 is instantly responsive no matter how heavily loaded it is.
Every few hours, though, it gets into a mode with serious UI-feedback lag. In this mode, when I tap any key or icon, the corresponding click-and-vibration feedback is delayed by up to one or two seconds. Often I can type several characters with no feedback, followed a second later by a rapid-fire sequence of the delayed clicks and vibrations.
When the phone is in lag mode, the lag occurs in all apps and with both keyboards I've tried (Samsung and Google). And it's not just during typing; tapping on any icon produces the same lag. Lag mode is not fixed by closing all apps, turning on Airplane mode, clearing the clipboard, switching to a different keyboard app, or clearing the keyboard cache or data. (Clearing the clipboard did seem to fix the problem on one occasion, but not subsequently.)
Rebooting the phone does fix the problem--until it comes back again a few hours later. I've tried booting into recovery and clearing the system cache, but the problem still comes back in a few hours. I have not had time to try a factory reset. But the phone is completely stock (APH1), no power-saving turned on, no debloating or esoteric settings or apps.
As I said above, most of the time the phone doesn't have this problem, no matter how many apps are running. And when the lag occurs, the phone is not hot and is not draining the battery. So it's not a matter of the phone being overloaded; rather, it's a specific bug in the UI feedback.
The problem arises at seemingly random times. I have not noticed any pattern as to what triggers it.
Here's a video demonstrating the problem, both for typing and for icon-tapping:
https://vid.me/iYya
And just for contrast, here's a video of the phone when it's working properly, with no UI-feedback delay:
https://vid.me/GF82
Again, when the phone is in lag-mode, it lags in all apps, for typing and for all icon-taps, etc. The videos show only one particular app for illustration.

Yes this pretty much seems to be happening across Note7...hope Samsung fixes this

I exactly have the same issue u clearly described above. My phone lags intermittently and no matter what I do, it doesn't go away. After some time, magically it comes back to normal.
Not sure how to fix this.. very frustrating!

Same thing for me as well. I've heard whispers it's an AT&T thing. Been trying to fix by turning off Battery Optimizer for certain apps and using package disabled. I've noticed it's most consistently caused by locking and unlocking again within a specific time window. Like if you're using the phone, then you put it to sleep, and come back within about 10 min, it does it's lag mode.

If anyone who's having this specific UI-lag problem tries a factory reset, please report whether or not the problem comes back after that.

I did the factory reset multiple times but it didn't solve the lag issue..

After the factory reset, did you restore using backups (e.g., smart switch, directly transferring SD card) or did you set up as a new phone. I was having very bad lag. I used Smart Switch the first time. After a factory reset and rebuilding from scratch (without Smart Switch) my lag problem is gone. There is some discussion of this over at Android Central.

Thanks. That's disappointing but important to know, both diagnostically and also to save everyone else the effort of duplicating the attempt.

I'd be very curious to see if an unlocked (no AT&T bloat) N7 has the same issue on AT&T. If I get a N7, I'm hoping to wait until unlocked versions become available.

I have the same problem. It's the only thing I don't like about the phone. Hopefully they will update it soon.

All samsung phones has that. A new custom rom will fix it.

Same problem, sprint... Stock, TouchWiz. Switched to nova and it doesn't seem to have helped much.

I'm finding the problem may be gone. It hasn't shown up in the last 48 hours (compared to several times a day up until then).
There's nothing I'm aware of doing differently now, other than having turned off Report Diagnostic Info in Settings|General Management. I'm skeptical that that has anything to do with the reversal (but not quite skeptical enough to try turning it back on just yet).
Perhaps the improvement is due to an app update, or perhaps it's a delayed effect of clearing the system cache (though the problem did crop up once or twice after the cache-clearing, before it stopped occurring). Has anyone else seen the problem go away?
UPDATE: The feedback-lag returned after about 60 hours. Again, no obvious trigger. Very annoying.

Hi guys,
I am having similar issues. Most of the times the UI is pretty smooth, but intermittently it starts lagging, opening apps takes 1-2 secs and scrolling the pages isnt smooth, its very annoying esp considering the device is barely few days old. Need some fix to this, or its a dead investment!

Wait, are you talking about the same feedback problem that this thread is about? Taking a second to load an app isn't necessarily unreasonable. But a one-second lag for haptic feedback defeats the whole purpose of the feedback and is clearly a bug.

What i mean is that the lag isnt just restricted to feedback, the phone seems to stutter overall, scrolling on pages and apps is jittery. And this is noticeable since when it doesn't occur the phone is buttery smooth! I tried the google now launcher and it still persists. Turning the animations to 0.5x didnt help either.

Oh ok. Yeah, I'm using the Google Now launcher too. For me, the lag problem disappeared about 58 hours ago though. Just out of curiosity, do you have Report Diagnostic Info enabled in Settings|General Management?
UPDATE: The lag came back after about 60 hours.

Just for completeness, I should mention that after the phone went into lag mode, I also tried turning haptic/audio feedback off and then back on. But the lag did not stop.
