TF700 very sluggish after waking up

Disclaimer: I searched the forums but couldn't find anything relevant.
Am I the only one whose tf700 acts really sluggish after it wakes up for a minute or two?
Is there any solution to this? It kills my main use case of the tablet (pick it up when I want to look at something in a pinch, and put it away when I'm done).
I'm on official ROM, rooter but not unlocked. This has been happening with the previous firmware versions as well.

I had the same problem for a while... most of the time I woke the tablet from sleep it'd be very sluggish.
I noticed that this happens when the wifi disconnected during sleep... it would have to reconnect and therefore all the services that required wifi would all start at the same time, throttling the system.
Turns out its the special setting in ASUS Customized Settings, "Disconnects network during sleep" that was causing this. It does exactly what it says, suspends network-related tasks when the screen goes off and resumes on screen on.
I initially turned this on because i was worried network tasks would drain my battery on sleep, but there doesn't really seem to be much of a performance difference with it on or off. So I'm leaving it off for now.

Hmm, I disabled that with the same battery concerns, but I'll give it a shot, thanks!

Also try a clean boot.
Hold down the volume down and power button when you power it on from cold. Let it go through the next screen without touching and it will clear cache automatically.
This does help as well anyway.

It's probably still quicker than most of us after we wake up..... Have you tried coffee?
Try turning off all bloatware. Mine used to be incredibly sluggish when waking up, and when I checked it turned on about 25-ish apps everytime i woke it up. Rubbish like Google Now, Talk, Gallery, etc. This slows the poor thing down to an insane level. Turned off all the random crap I would never use anyway, did a coldboot (sbdags describes the process up one post ^) and now it's instantly awake.

[Q] Wifi issues and battery drain lollipop 5.01

Purchased the shield tablet with controller yesterday. It came with 4.4 and seemed to run fine (wifi speed very fast etc) Soon after upgraded to 5.01 and the problems started..
There seems to be the Miscellaneous entry under the battery settings which is using around 40% of the battery according to the info. Battery drain seems to be quite fast.
Since then, today I decided to unlock bootloader and root the device which was successful. Miscellaneous entry does not seem to appear anymore
However there is the wifi issue that has occurred since I updated to 5.01. When the tablet goes to sleep and when I wake it up, connection is lost (and rather annoying where a game needs to download 1gb+ of data). It does also occur while I am using the tablet. Wifi sometimes just disconnects (and the entry on the wifi list for my router is showing as "saved" - clicking on connect, starts it up again..
I have checked through the settings and disabled the wifi off when sleep option as well as gps only for location etc, but still to no avail.
Has anyone encountered and solved this issue on lollipop? Or is this also an issue with 4.4? I did not use it for long before updating to 5.01 hence not sure If that problem would occur then (but seemed blistering fast for the hour or so when I was testing it)

I'm having the same issue. I looked on the forums on their website and it seems this is still a problem for a good amount of people. Can't find any solutions though. Thought maybe a hard reset might do the trick but that didn't help. Pretty frustrating...

Wifi connectivity seems ok when I am near the access point, but seems that the sensitivity somewhat has been reduced since the update (as the connection was more stable and reliable further away from the router on 4.4)

Hows your battery after rooting? Does it still drain horribly?

I have the same problem

THAT DRIVE ME CRRAAZZZYYYY!!!! the same happens to me everyday and I can't find anything about it online.. somebody please solve our problem!

I think I have partially solved the problem. The below is what I have done (Will at some point activate some of these options one by one and see which one would be the main culprit)
Settings->Wifi->Advanced Wifi - Turn off Ethernet override and turn off "scanning always available"
Settings->Wifi->Advanced Wifi - Keep on "turn wifi on during sleep" - Can turn this option off for some additional battery life
Settings->Controller->Disable "enable gamepad mapper" - From other sources it seems that this may be one of the main culprits in battery power sucking
Settings->Location->Turn this off (If wanting to keep on, leave it on GPS only)
Using the above settings, and charging the tablet approximately 15 hours ago, the battery life of the tablet has decreased by only 6% (and currently there is no - miscellaneous showing on the battery option)
There is still the issue with weak wifi (It works perfectly well when the device is near the access point) perhaps a future update may increase the sensitivity somewhat

One other important thing.. I decided to hard reset the tablet after upgrading from 4.4 to 5.01. This may help. Once this is done, then follow the steps above

Did miscellaneous ever come back for you? I did reset and changed all the settings and miscellaneous wasn't there for about 2 hours and then came back. Down to 50% battery with miscellaneous taking up 17%. I'm now wondering if this is an issue with the software or my tablet in particular...

For me, once I disabled the gamepad mapper, I no longer experience the outrageous battery drain issue, and misc. no longer appears in the battery status page and has not returned.

I didn't experience this miscellaneous battery drain until the most recent 2.2 update. When I upgraded to lollipop I did a complete wipe, rooted and unlocked the boot loader. When I updated to 2.2 I just flashed via recovery and wiped dalvic/cache.
I'm wondering if I need to do a complete wipe. I haven't seen any solutions to this, but it's strange that it just now started to be a problem for me.

The main culprit seems to be the "game mapper". - the system that maps the controller to touch screen controls. I guess perhaps updating to 2.2 turned it back on. Turn it off via settings and reboot and see if that makes any difference.

Thanks for the reply,
I turned the game mapper off via settings, and still got the misc. drain, so I froze the nvidia game mapper and a few other nvdia controller system apps via titanium back up and I'm still getting the misc. battery drain. I just wiped the cache, and dalvik cache 3 times, but I doubt that will do anything. It's looking like I will have to wipe and do a clean install, just seems so weird that something that didn't even change the android version number would give me this problem.
It's really annoying as the battery drains soo fast (like 20% just reading a book in my e-reader app)
before I wipe I just wanted to see if others had this problem with the latest update, as it doesn't appear too common I will do a full wipe later when I have time. I hope that fixes it.

I have the exact same issues as you describe. WiFi is about 25% of what it should be even standing right next to my netgear nighthawk. All other wifi devices work fine in the house. Disabled game mapper and my misc is still running the battery down. Tried wiping to factory with no luck. System UI crashes sometimes and the tablet freezes up constantly (especially when using Chrome and Google search). I'm thinking it could be Google play services related but not definitely sure.

Sheild LoLi screen changes orientation, goes black then to homescren
So seems you peeps having same problems I have experienced and troubleshot as well, but here is one I can't figure out...
Playing game (TaiChi Panda mmorpg) which only runs in landscape mode. I will be playing and all of a sudden tablet tries to change orientation away from landscape, the screen goes black (or has game shrunk and stuck in middle of screen) then will go black and puts me at my homescreen which is non-responsive and most times I have to hard power down. I've turned off screen/device rotation and still does it. The problem also happens with other apps and stuff at times as well. I've even turned all notifications etc I could cause thought maybe something was trying to interfere.
I have the screen flicker as well at times, feel like watching old black and white movie way it flickers.
Battery lifes went up with some tweaks found here (ty vm!).

Sorry to bump such an old thread, but has anyone figured out what it causing these issues on Lollipop?

Anyone else's S7 waking up randomly?

My screen will turn itself on every now and then, I can't seem to find anything consistent about what causes it to do this. Maybe some app I have installed is causing it but I've never had the issue on other devices (ambient display is set to off in my case)

It sometimes happens to my phone too. I don't know what causes it. And I have no problem about battery drain, I have just used phone for 1d2h33m35s with 6h20m screen on time. It was happenig to me in S5 too. I use same apps. I think an app causes it.

Mine woke up twice yesterday in the middle of the night, definitely strange.

Yeah I wish there was some place to see what apps have recently used wake lock or keep awake permissions to see if it's something I installed or what. I disabled most samsung bloat and use mostly just the google apps and then a few casual games like hearthstone

I have disabled lots of Google apps and Samsung bloatware since I use phome first day. Maybe we all disabled one wrong app

Mine does it too occasionally

Mine does as well. At one point it stopped and battery was much better, but it has started again.

yeah I'm pretty bare bones when it comes to android phones, I like minimal background apps and go for battery life and speed. still can't figure out what on earth is waking my s7

I am having the same problem with my Galaxy s7 edge. it will randomly wake the lock screen, even when not getting a notification. Its really anoying. I was also having a problem with the screen lighting up when I recieved a text message using Verizons message + app. changed to samsung message and had the same problem, even with notifcations turned off! finally got it to stop by using google messages, but now when my phone is face down it doesnt do the cool light up on the edge. really frustrating.

[Completed] [NeatRom] [TerribleConflict] [BUG] [ScreenGlitch] [HELP] Samsung i9100 Galaxy SII

Good morning every1,
I installed NeatRom on my i9100 and worked marvellous for months, now is a living hell! Not blaming the Rom itself but some kind of conflict between hardware and software.
Bug Description: screen strange behavior, in certain conditions won't turn on or will show strange colors, over illuminate or darken display, while at start up it will always work fine.
Trigger: locking the screen normailly causes to blackout but it will not turn on again on most tries, pushing the power buttom or the home buttom is equally uneffective most of the times. However, reseting the phone by removing the battery (since there's no display is the only way) will allow the phone to start normally: normal brightness, normal colors and normal operation everytime.
Fixes tried so far: I've reset the phone to factory, erase all cache, partition and delvik, and reduced the amount of apps to keep ram very low in usage. Also, I've removed the phone cover to check the screen connections, check the cable to see if its not broken and everything its fine. The display is not broken or otherwise damaged.
Opinion: since the display works fine at start up and would be working normally for as long as I don't lock it, I'm discarding all hardware problems of the screen itself; and I've removed all apps to avoid conflct of other software and it still has the same problem. Therefore, I think there's somekind of conflict between NeatRom and the screen (drivers maybe).
PLEASE HELP! :crying:

Touch lag issue when using Adaptive smooothness

I got my Note 20 Ultra back on November and encountered an annoying issue when Adaptive refresh rate is turned on and watching YouTube videos. When YouTube first starts the display will run at 120hz, but after a few seconds it will drop to 60hz. When the refresh rate drops, the first touch of the screen is interpreted as a touch and hold instead of a single press. The display will then jump back to 120hz, but the display still thinks I'm pressing and holding the screen when I've already let go. If I then touch the screen again while in 120hz the phone thinks I've done a double tap (presumable completing the first tap and then immediately registering the second tap), which causes the video to seek forward or backward, depending on where I pressed on the screen the second time. If I tap the screen the one time but allow the screen to drop back to 60hz after it jumps to 120hz from the first tap, then the first tap seems to be ignored as my second tap acts like a tap and hold again.
What's interesting is that as long as the display stays at 120hz, all taps after the scenario above work fine. A single tap will open the playback overlay (pause/play button, seek arrows, etc) like it's supposed to, but once I leave the display alone and it drops to 60hz this whole problem starts all over again. Since adaptive refresh is tied to the brightness sensor, this problem does not present itself in a dark room since the display stays at 120hz in a dark room. Also, if I turn off adaptive refresh rate and have the display stay at 60hz all the time then the problem is not present either. I also will occasionally get non responsiveness on Brave Browser but I can't say for sure if they are related.
This has frustrated me so much I did a factory reset and interestingly the issue did not re-appear at first with a fully updated YouTube. Once I updated/installed other apps (including Galaxy store apps) the problem returned. I don't have display overlay apps installed, so I suspect it's a Galaxy store app but I can't pinpoint which one. I don't believe this is a hardware issue, so I'm curious if anyone on the thread has had a similar issue. I'd like to report this to Samsung but I have no idea where to even report this.

Sounds like you've figured it's a software program. You should update one at a time and see if you can pinpoint the issue. Try to not to install 3rd party software until all you need to update gets updated and phone is working fine.
Or
I would say try using a package disabler and try disabling the apps you suspect to see if any improvements. It might not be a Samsung app as others would be facing the same issue you're having.
As always don't restore settings/app data from backup etc other than media, messages, logs.
I'm using adaptive and everything is working fine on my end. Snapdragon variant here. Albeit I keep a number of Samsung apps disabled as i don't use or need them running in background for no reason.

Can you provide a list of apps which you have disabled through adb?

have you tried diff version of youtube that can help

I use package disabler pro bought from their website. It gives me a great on demand enable/disable option.
My use case might be a bit different from yours as I have about 160 packages disabled at a given time. I guess I can provide a list and you chose what you want from it.

I'll try uninstalling apps again to see if the problem can be resolved that way. On the latest version of Youtube it worked fine before I started installing more apps. I kind of don't want to do a full factory reset but if I have to so I can narrow that my be my only option. I'm wondering if there is another software I can run on my phone to see if any apps are interfering with the display or adaptive refresh rate?

I ended up doing a factory reset on my phone. The issue went away for the most of the day but returned again by night time. Same issue - when at 120hz and drops to 60hz the issue is present. It's not just Youtube, it's on any app, including the home screen. The first tap is always interpreted as a tap and hold, so single tapping an app icon brings up the tap and hold menu, and single tapping on the home screen brings up the home screen customization screen. Another test I did was turn off auto brightness, then turn my brightness down to the lowest setting. After that the display stayed at 120hz and the issue did not return until I either set the brightness up manually or turn auto brightness back on. I also tried in safe mode, and the issue was not present there either, but I can't tell if the device every went into 120hz or not since all 3rd party apps are disabled. At this point I have no idea what it is. The app setup was fine during the day, no new apps were installed, but the issue returned. Seems like I have no choice to but turn adaptive smoothness off and leave it at 60hz.

Just to add a little more interesting information here. I had someone else use the refresh rate monitor app on their Note 20 ultra (Tmobile variant), and their display operates differently than my Verizon variant. On the Tmo variant, when the screen drops to 60hz and the screen is tapped, the refresh rate drops to below 60 (12, 34, 48, etc) but then goes back up to 120hz after the app opens. Mine just goes immediately to 120hz and then gets that tap-and-hold behavior. So clearly the screens software or firmware is behaving differently here. I'm wondering if we have any other Verizon variant Note 20 Ultra users on this forum that could also test?
