Same thing happens with mine. While charging the screen will frequently come back on and then go off again in a few seconds. I haven't noticed the behavior when it's not charging. It's almost like something is running in the background causing it to wake up when charging.

I've noticed it slightly in low brightness but not as bad as the Tegra3 based N7 and TF700t. I'm guessing it has to do with prism if that's the case.

[Shield General] Eat it iPhone:
Screen "Flicker" is the auto brightness, try changing to a manual brightness. I have noticed the orientation is very sensitive, sometimes when sitting down or moving a bit it will flip orientation on me, seems overly sensitive, whereas ive used other tablets that were not sensitive enough. Sounds like you may have had a few bad ones but the screen "issue" seems to be common, the light sensor seems to be overly sensitive (assuming changing to manual brightness resolves your case).
[Shield General] falconw13:
I haven't noticed any type of flickering on my TN7 or my new shield tablet. This could partially be because most of the time i have the brightness setting to manual. Its seems as when i have it on auto the screen is just a little too dim for me. Although, when using the tablet outside i usually have it on auto and the screen chooses the correct brightness so it can be best viewed.
[Shield General] Linuxslate:
As I mentioned, I haven't seen anything I would call a "flicker", but I am glad someone mentioned the auto brightness.

To me, the auto brightness seems a bit "hyper" -- too much gain.

A slight change in orientation to or away from room lighting causes a drastic change in screen brightness.

The same for a shadow from my thumb if I hold the tablet in landscape.

I guess it could cause a flicker, but it depends on the context of timing --- Kinda like "the dinosaurs died out quickly", vs. "the quark decayed quickly".

Also I want it to be clear that I am not complaining about my Shield Tablet. It's just that xda-forums are a place where things are discussed in minute detail. It is not a problem, issue or complaint.

I have no interest at all in using my Nexus 7 (2013) (or any other Tablet) since I got my Shield Tablet.
[Shield General] rushless:
The weak wifi appears to be the priority focus Nvidia is now giving the tablet. Question is will they go into denial mode like Asus did with the T700, or address early and revise the design IF needed. Sales were badly impacted for the T700 and a high return rate, per Best Buy.

Hopefully a simple firmware fix, but weak wifi is almost always antenna related for devices like this.
[Shield General] bryctucker:
I don't think any of the shield tablets I've used so far have had Wi-Fi problems.
[Shield General] markymark567:
I have a similar issue. Check it out here:

Shield tablet screen defect: http://youtu.be/PUP_zAgpbxs

I have been on and off the phone with Nvidia trying to get them to ship me a new one for free. They refuse and I refuse to pay more shipping charges just to get a working device. Great tab otherwise. Just was unlucky and Nvidia has terrible customer service. I'm just returning it
[Shield General] bryctucker:
Man, I'm glad I don't have that issue. That looks like some sort of video driver.
[Shield General] markymark567:
Tell me about it. Its been like that since I first turned the tab on 3 days ago. Nvidia refuses to acknowledge my issue and insists I pay return shipping and a restocking fee. I don't understand why I should pay more than every other customer just to get a properly working device. Nvidia has pushed me away from sticking with this tablet.
[Shield General] Techguy18:
The flickering when the content changes is probably Nvidia's PRISM at work. Basically, it tries to optimize brightness and colour so that power usage is reduced.

Instead of maxing the backlight and telling the pixels to display dark grey, it dims the backlight and tells the pixels to display light grey, saving power.

It is an advanced form of autobrightness, and I think it can be disabled. But a continuous flickering should not be caused by this. This should happen only when the screen is refreshed.. like new page or picture

That IS a probelm.. for some reason the bottom is getting clipped and being sent to the top.. send them a picture.
[Shield General] vimjam:
I don't have the flickering problem either...but the tablet used to wake up constantly when charging ...but after I did a factory reset everything is fine now .... My only complain is the poor WiFi performance
[Shield General] Linuxslate:
Mine seems to have "caught" both problems.

The screen flicker only happens under certain conditions; perhaps ambient lighting conditions. Next time I see it doing it, I will try turning off auto brightness. It is not doing it as I type this, even if I scroll around, switch apps, etc., but I am under dim, natural morning light.

The constant waking while charging is far more iterating.

Factory reset seems to be a drastic way to fix it, especially if it just comes back. I do not have any need for a tablet I have to factory reset every week.

I tried to do a logcat in a terminal while it was doing it, but of course the logcat isn't running while the tablet is sleeping, so it did not tell me much. Just periodic "onResume called", but no indication of the cause.

I did see something that led me to think it was looking for the shield controller or some other input device. I do have the shield controller, but I have connected to BT input devices (keyboard and mouse), and those devices were not around when it was waking. BT was off.

I'll post if I find out anything.
[Shield General] Seanichigo:
there's an option to turn off the screen while charging in the developer options.
[Shield General] Linuxslate:
That's not what we are talking about. It's not that the screen is /staying awake/ while chargeing, but it is constantly re-awaking (from being off) during sleep.

Mine was doing it approximately one a minute during charging.

Interestingly, mine has stopped doing it. I had tried several reboots, various settings, etc.

Then, one morning, my Shield Tablet crashed -- Spontaneous reboot the first time I woke it after taking it off charge. It is the first and only time I have had a spontaneous reboot (my Nexus 7 Flo did it almost daily, sometimes twice a day with general use).

Since then I have not seen it wake during charging.

So what's it's latest affliction? It's disease duo jour?

It is now failing to rotate the screen. I am using it for work note-taking, so this is a lot of wake - sleep - wake cycles. After a few of these, rotate will just stop working -- freezing it in what ever orientation it was. The lock screen will not rotate, and it will not rotate after un-locking.

It works fine, but it is stuck in what ever screen orientation is in.

It takes a reboot to fix it.

If the pattern continues, I assume this problem will spontaneously abate in the next day or so, and my Shield Tablet will develop a new one -- perhaps spontaneous occasional levitation, or something like that.
[Shield General] Keithn:
Have you tried flashing one of the otas? There is a thread with the links to download them from nvidia's server. That and or a factory reset ?

Sent from my One M8
[Shield General] Linuxslate:
^^^^^^ (jealous)

As of right now, my Shield Tablet is working fine. It has only done the screen rotation lock issue once this morning. Things would have to be worse that they are right now for me to do a factory reset.

I also realize that the simplest explanation for these "errors" that seem to cure themselves is operator error.

I only reported the wake while charging issue because some else posted about the same problem.

I am still 100% percent happy with my Shield Tablet, and the thought of going back to my Nexus 7 2013 has not even begun to have the faintest inkling of the merest start of even beginning to cross my mind.

[Shield General] g1xx3r:
I bought one on launch day to replace my aging GNex10. I was verry happy with it until I read about the crack issue. Lo and behold when I checked mine, it had a crack. Also the power and volume buttons were a pain to use with little to no feedback. My wifi was okay using the Asus RTN66R 5ghz.It would fluctuate but nothing showstopping. Well today, I decided to get a replacement from Gamestop. I dont know if it was a first bad batch, different factory or what but this one is a definite improvement. The power/volume buttons are spot on, wifi is more consistent only dropping to 150mbps were it would sometimes bottom at 24mbps. No cracks out the box and I have run quite a few benches to get it hot. Seems to bench higher under Davlik as I havent changed to ART yet like I did with the last one.Time will tell as the last one had a crack in less than a week of usage. Is there any way to tell batch, plant , etc?? So far so good! :good:
[Shield General] markymark567:
+1 I got my second tablet from GameStop on Friday and I am completely happy. My first one (from nvidia store) had a bad screen driver causing the screen to not display correctly. For the record I have never had an issue with WiFi or Grid streaming on either device. I have a crappy century link router too. Works fine. Just hope cracks don't develop.
[Shield General] timskyline86:
If you are rooted you can turn off PRISM. (Rooting is not hard on this tablet and you loose nothing)

Install a terminal emulator.

Then run:

$ su

# echo "0" > /sys/devices/virtual/tegra_dc_ext/tegra_dc_ctrl/subsystem/tegra_dc_0/device/smartdimmer/enable
[Shield General] Lostatsea23:
The flickering is prism. Most likely will be able to be turned off in an update.
[Shield General] Linuxslate:
My problem with screen rotation is related to the browser.

I mostly use the default (AOSP-like) browser, not Chrome.

When it won't rotate, I just swipe away the browser (in the normal task selector), and it immediately rotates as it should.

Could be related to 'Open Pages in Overview ' or 'Auto-fit Pages'.

At any rate, it is a much easier work around than rebooting.
[Shield General] roustabout:
On some of the T4 devices, the flickering wasn't actually from the Prism feature but from a dynamic backlighting feature called "smart dimming" that was changeable only (afaik) on rooted devices by changing an /etc file.

The screen flicker at low ambient light levels and low screen brightness was pretty bad.

You might want to get a look at /etc/power.xxx.rc (don't know the device string for the ST) - on the HP and Asus T4 based devices, the file was /etc/power.fig.rc)

As shipped, smart dimmer was enabled at all power settings even if the "tegra prism dynamic backlight" feature was disabled in the Settings panel.

If there's a screen resolution in that file that matches the NST resolution, edit that line; if there isn't, change the values in the last line of the file from "1 1 1" to "0 0 1," which applies to any unmatched resolution:

/sys/class/graphics/fb0/device/smartdimmer/enable 1 1 1

to

/sys/class/graphics/fb0/device/smartdimmer/enable 0 0 1

Sorry if this is addressed elsewhere but i could not find it.

I have a T999. I moved out of TMO coverage and changed to straight talk using AT&T. Everything (call data) works great.

I am looking for a AT&T Kit Kat TW stock port if there is one out there. I looked in the Dev pages and didn't find any.

I can build it if I need to. but need to know, can I just take the stock AT&T rom and change the modem and flash with ODIN or with a custom recovery?

Right now I'm newest stock rooted. I used to do a lot, but it's been a while.

Never flash firmware from another device. Currently there is only likewise. TMS3KK will be out very soon. I've got an NE4 port in the works but just haven't been home much so haven't finished it.

You can flash AT&T roms, but unless properly ported you may have some issues, primarily with the network.

[Android Q&A, Help & Troubleshooting] jdmanley87:
I mean I guess the reason I ask this question is because the radio firmware on most if not all phones is closed source, and hence we don't really know what it does when you tell it to turn off. Is there ever such a thing as an open modem for GSM?

In regular Linux, some WiFi radios have fully open source drivers.
[Shield Q&A] dcaplinger76:
Having some bad WiFi with my new Shield tablet.. Where my Note 3 or Tab S have full bars my Shield only gets 2 of 4... Low link speed too. I was hoping it was a software issue but not so sure anymore..... When holding the tablet in portrait, my hands hold the bottom part of the tablet, moving my hands increases the bars and then move them back and they go away. I guess the WiFi antenna is down there? Either way, it is easily blocked. Anyone else notice this?
[Shield Q&A] Turbo Brian:
there's a big thread over at geforce.com about it. you're not alone. 2.4 is OK-ish though still weaker than my other devices but 5ghz is terrible. where my note3 gets 108mbit 1 floor down the shield tab gets 6-12mbit and sometimes no signal at all. heck, same floor as the router and 1 room over with 1 wall between and 15ft total distance and it only manages a meager 24mbit connection when my note3 is at 150mbit and my surface3 is 300mbit. hoping its not a hardware design flaw and is just poor drivers or firmware.
[Shield Q&A] dcaplinger76:
Yeah its a shame really. I wouldn't expect bad WiFi signal really with any device released recently.
[Shield Q&A] rushless:
Maybe they lowered the mW output of the wifi to help mitigate battery drain from the gpu. That can usually be fixed with firmware, for about a 3% hit on battery life.

If antenna related, a power increase will not help much if at all. Only fix then would be a production revision.
[Shield Q&A] dcaplinger76:
Well I guess I will hope for the first possibility.
[Shield Q&A] rushless:
I might be a bit under on the battery life hit. Maybe 5% is closer. I hope so too, since was going to get the 32gb model when released.
[Shield Q&A] dcaplinger76:
Here's a look at Note 3, Tab S, and Shield all sitting on the router. Note the link speed on all.

It could be that your 802.11ac router is using the wireless-b/g standard instead of n

Does the Shield not support ac? Dang, I thought I read it did before I bought it.
[Shield Q&A] Goodeman:
Nope only up to n
[Shield Q&A] rushless:
There is already a way to increase the power with the wifi optimization setting and reports are minimal if any improvement. Looking more like an antenna issue, but always a chance something else. Need to get a response from Nvidia. If they go silent on the matter, that would be bad.

Wonder if the 32GB will have the issue as well? A delay in the 32GB (beginning of September) would suggest a design revision might be in place.
[Shield Q&A] aznmode:
I just got mine today and the wifi is pretty bad on this compared to my note 3. I tried running a test by walking away from my router with both the note 3 and the shield tablet. Eventually the shield lost communication with my router while the note 3 still was able to acquire at at least 2 -3 bars. I was really looking forward to this tablet but if I can't go to another room without losing connection then it's pretty pointless.
[Shield Q&A] aznmode:
Damn it. This is unbearable. I can't even play modern combat 5 which requires constant connection. It keeps disconnecting.

Running wifi analyzer I noticed the connection jumps a lot. I would love to open her up to see if it's a connection issue but not sure how to. Have to wait for a tear down.

May I ask which router you have ? I had a lot of issues with one particular brand- Netgear, which is very picky in terms of devices . It works with Mac retina, but it did not work with my Vaio , Now I am using cisco ea4500 and all of my problem gone, I might be wrong but it always good to check in on other wifi-s
[Shield Q&A] dcaplinger76:
Netgear r7000 Nighthawk. Shield tablet is my only problem device on the network.

My Tab S does great in the same spots. This morning has been actually great though, not as good as my Tab S but it also costs a lot more so probably expected. Here's 2 speed tests for comparison. First one is Tab S and second is Shield .
[Shield Q&A] Evo_Shift:
Mine works fine with an older netgear router. The classic 802.11g 2.4Ghz. Same speeds as my nexus 5 gets pretty much everywhere in my house. I don't use the streaming feature though so can't comment on it.

An nVidia guy did respond to a report of that 24Mbps thing. Maybe that bug affects more than just the WiFi Analytics app.

In my case, my issue is more range. The shield has a weaker wifi.
[Shield Q&A] aznmode:
So I received a replacement last week which had slightly better signal than my original but it had a much warmer yellowish screen so there was no way I'm going to keep that. I figured then that this has to be a hardware thing so I opened up the back and made sure all the connection for the radio was properly seated. And to my surprise it made my wifi on par with the replacement and with my Samsung note 2014. I don't recommend you open yours of course but maybe there's potential QA issue with these tablets? I recommend maybe you get a replacement from Nvidia and hopefully you get one with better wifi.

Top is note 2014, bottom left original shield, bottom right replacement.

[ONE Q&A, Help & Troubleshooting] hashim71:
Hello All,

I got the Chinese OPO 16GB because it satisfied all the frequency requirements for my Carrier (Rogers Wireless, Canada).

I absolutely love the phone its an amazing device.

But I am having major issues when it comes to reception with this phone. I am coming from and iPhone 5S. This phone works very nicely with LTE and speeds are good and everything, but it has issues locking signal when it comes to 3G/HSPA. When I am indoors I get absolutely no 3G coverage at all... where I used to ger 2-3 bars with this phone thats impossible it completely loses coverage as soon as I step indoor somewhere. Just for kicks and giggles I experimented with this at the mall. I turned the phone settings to WCDMA only and managed to lock 5 bars on HSPA standing underneath a sunroof at the mall. As soon as I stepped in a covered area merely steps away from the sunroof I would lose coverage.

It is beyond me to understand how a phone can have such a sensitive antenna.

My main issue isn't 3G... Since I get LTE everywhere with this phone. But the problem is when someone is calling me the phone keeps looking for 3G signal to drop to but cant because it cant find 3G signal and all my incoming calls go to voicemail.

Anyone have any ideas? how I can fix this? or is anyone else going through the same thing I am?

Thanks in advance.

P.S I am running the latest CM Nightly.
