[Q] Screen turning on randomly - Transformer TF300T Q&A, Help & Troubleshooting

I feel like I'm the only one with this problem.
I updated my TF300T to 4.2.1 the other day and it's fantastic. Super fast and smooth. However, when I attach it to the keyboard dock and lock the screen, it will randomly turn on a few minutes later and stay on. This is SO annoying because it drains the battery without me realizing it. I looked around and I think it's an Android 4.2 problem, but I'm not so sure. Any suggestions? Thanks.

Hi,
I think the only way to know if its an Android 4.2 problem it's to try a rom on 4.1. Did you have the same issue before or its new ? Perhaps it can be a hardware problem on your dock like touchpad ( You can wake up your tablet when you touch it normaly )
I'm on Cyanogen 10.1 ( 4.2.x ) and haven't this problem
Which rom do you use ?

I have the same problem after updatinmg to 4.2.1 and it was not present before. I have already done a factory reset but it didn't help. I have found out that the screen is switched on and tablet is connecting to wifi. So I have tried to disable synchronization and still the issue is there. Then I have tried to disable WiFi and this seemed to help. So I would say there is some application that wantst to connect to internet and cuses tablet wake up. But how to figure out which application?
I am swithing my wifi router off during the night and swithing on in the morning. Tablet connected to wifi after I open it and pres power button and unlock with 4.1 but with 4.2 it connects without touching anything. And I have disabled WiFi in sleep mode in wifi advanced settings settings and also in Asus settings.
Any hints? Thanks.

Download BetterBatteryStats from google play and run your tablet for a day while this app is installed and you should be able to tell by looking at wakelock information as to what is turning on the screen.

Thenk you for your hint, I have run the app, but not it is not so clear to me, how to interpret the results.
The only thing I could recognize is, that the problem is only when tablet in in dock. Between 7:00 and 17:00 it was undocked not touched at all, and between 19:00 and 6:00 it was in dock. So obviousy the problem is somehow related to dock. Custom reference has been set after connecting to dock.
Could you please help me?

My Infinity is failing to go to sleep, and instead overheating

I have had a tablet overheat since I had the Transformer Prime which after a few updates for ICS from ASUS the tablet started overheating when I thought it was sleep.
Now I'm seeing this symptom return with Jelly Bean on the TF700T. Is anyone else having this problem?
If it's happening like that it is most likely an issue with an application you have installed. Check to see what's using the most power in the power section or install something to see what's keeping the device awake.
Mines been solid since jb and have had no overheating or sleep issues.

Google maps does that, turn of gps and location service....i think its the last update of google maps.
and because i dont use that software, i "delete" the app
I've had the same problem and posted in the Q&A section but I didn't know which app. I'm going to uninstall maps (or at least all updates) just to make sure.
I'm certain it's not an app but the OS. My Infinity wasn't overheating until it got JB.
It worked fine in ICS with the same software that I migrated over from when I had a TFP.
It did it again today, it was getting low on battery with only 50% left on the tablet and the dock completely depleted which I was going to recharge, I turn my had and look back and noticed it self-rebooted, but right after the ASUS logo it went to a black screen and it's just stuck like this until I can scramble around and find something that will fit into it's tiny little reset hole.

I'm also having this problem. Turning off gps didnt help but toggling the wifi was effective. Ive had it on for 1 day and 6 hours and still have 95% with relatively little use. The biggest battery draw was tablet idle.

Mine's done this a few times since JB, too. Never before.
You can hold down all three hard buttons to force a reboot. Hold them for about 10 seconds and you'll feel a quick vibe.
If its ok with wifi off sounds like the tablet might be trying to access the network
As you can see mine has wifi on all the time and its been 15 hours

The particular problem with mine is google maps forcing the wifi on when its supposed to be sleeping. When I manually toggle wifi off it behaves correctly.

[Q] Auto off WiFi never comes back on

Anybody else having trouble with the WiFi not turning back on after waking from sleep? I'm using the "Only when plugged in" option for "Keep Wi-Fi on during sleep" to conserve power.
What I'm seeing is when I am connected to a WiFi network and then lock the phone long enough for the WiFi to turn off, the WiFi will say it's on in the settings menu but won't show any available networks even if I hit "Scan". The only way to reestablish the connection is to toggle the WiFi on and off.
I've disabled Smart Actions because I thought that was interfering but it didn't help. I've also booted into Safe mode with the same problem.
My router is a Linksys WRT54GS. The settings are: SSID broadcasting, WPA2 Personal (AES), G-only.
I've attached before lock and after wake screenshots to show what I'm seeing.

I kind of see the same thing. Wi-Fi works fine until I leave the range of the router (e.g.leave the house to go to the store). Upon my return I see the same thing your screen shot shows. Turning off wi-fi and turning it back on solves the problem No other phone I've ever owned has ever done this.
I've tried auto connect, leave it on and off during sleep, reset the router and nothing has had any effect.
So it's not just me. I wonder if this is present on all phones or if we just got a bad batch.
EDIT: Well... for some odd reason the WiFi came back on from a sleep just now. I don't remember changing anything other than installing the 4.2 camera and changing the build.prop to a Galaxy Nexus. I shall investigate further.
EDIT 2: Could this perhaps be an ICS issue? (I came from a DROID X with GB) I ask because a GSIII in our house seems to be doing the same thing.
Not sure. My GS III will connect automatically without fail. I just got home with the Razr Maxx HD and had to go through the off and on routine to make it connect. I had the GS III last evening and it reconnected as usual once I got home.
There's an extensive thread on the Moto support forum where everyone is complaining about the wifi signal dropping randomly when connected. You are the only other person I've seen with our issue.
I haven't played with the GSIII extensively so it might have been a fluke that it did that.
I did see that thread but the Motorola support site has been loading very slowly on my end so I haven't been able to look through the whole thing due to my impatience with it.
Something's definitely wrong with the site. There's a thread for that as well LOL.

Blake_wakelock - Wireless Shield controller driver seems to be the culprit

Hey there, good people.
I don't know if someone has face this wakelock before or not, neither if there is a workaround for this.
I found that the Wireless Shield controller driver is the culprit of this wakelock. In short, this service is the one in charge to pair your wireless controller with your tablet.
The service start everytime the tablet boot up, so is auto triggered without reason, and becomes a wakelock that last the time you have your tablet ON. I've tried disabling the boot receiver but after reboot the control won't pair, which is kinda silly, considering that blocking the autostart on boot doesn't disable the app itself.
This service will autostart and will keep running even if you turn off the controller. The only way to stop it is by killing it, and that's quite annoying. Is there any possible fix for it or i am the only one facing it? I'm on OTA 1 or whatever comes with the tablet (Stock)

Did you get your wakelock issue solved?? I had the same issue also. Download 'disable service' from the app store and navigate to the system apps and find the 'SHIELD Wireless Controller Service' and disable the service. It solved my wakelock problem .

But if you do that, the controller becomes useless because it wont pair.

You are correct sir. I recommend leaving it off until you need to use it, otherwise it will just be a drain on your battery.

this is an issue with 4.4 kitkat. to fix it temporarily, toggle airplane mode or restart the phone, then toggle wifi.
for a permanent fix, i've read that deleting the wps_supplicant file under data/misc/wifi will do the trick. note that this will also delete all your saved wifi networks and passwords.
what i'm trying at the moment is just editing that wps_supplicant file - cleaning it up and just keeping 2 wifi networks in it (one for work, one for home). So far it's working well.
Just to make it clear, search the internet, other phones on kitkat intermittently have this problem.
What I'd try is turning off BT temporarily and see if WiFi works. Also, some people have reported WiFi issues after installing and using certain apps (a flashlight app, the app GasBuddy.) If you have one of those, try uninstalling and restarting the phone.
If that doesn't help, try restarting in safe mode to rule out another third party app. Long press power like you want to power off until the power off dialog shows, then long-press the "power off" until the safe mode prompt comes. If BT and WiFi works in safe mode, it's a third party app problem.
Hey mines was broken and I tried everything in every post around the web.Slap it,wipe cache,Factory data reset, safe mode nothing worked? then I enabled developer options and switched select runtime from Dalvik to ART and a reboot happened...Android is updating it said as I waited patiently. Maybe just maybe,BOOM I got WiFi Yes.update
WiFi gone again fix was temporary

Thank's once again.

Bluetooth creating constant notifications

So with bluetooth on, I get a constant notification whether a device is connected or not. This is all after the MM upgrade.
Steps already taken:
- Verified reminder is turned off in accessibility.
- Cleared cache.
- Removed all BT devices
- Factory reset.
PLEASE HELP
@jasong127
Try settings > wireless and networks > nearby device scanning > off.
Let me know if this works. It uses BT even when off. I turned mine off long ago. Never had your issue and unsure if this may solve it.

That was already off. I think that when my car (chevy mylink) was connected, there's an option to "Allow Contact" or something like that. Problem is, when the truck is no longer connected, all the other options move to off, except this one.
Happens with one other device too (my home phone system). I have to unpair them and it stops. Pretty much seems like a bug to me.
I will have to test this on my ford transit the next time i use it. I do know it always resets the 911 link, which is annoying.
I'm having the same issues. Just did a factory reset and have not paired any bluetooth devices. But the minute I turn on bluetooth I start getting notifications. Help before I flush my phone.

Did you have items at one time that were paired? The way I found out the solution is to unplug ever BT device in my house and start one by one. BTW, I have 1 home phone, 3 speakers, and a computer that all use BT. Turned out to be the home telephone that was the cause of it.
