[Q] Can the Dell S7 be restored to factory...

So, I've just picked up a Dell Streak 7 and so far I'm not overly impressed with the Froyo OS. If I keep it I'll likely look at one of the custom ROMs here. But I'd like to know if after flashing to a custom ROM if I'll be able to return to the factory setting? I'm asking because I'm within the store return policy so if I really don't like the tablet I can return it for a full refund.
Thanks in advance.

Everything you want to know is in the custom ROM threads and in this section. Happy reading!

Thanks, I think?
I guess I'm off to wade through them.

To my knowledge, there is no going back to the wifi only version after trying honeycomb. I installed DJ_Steves and successfully got it back to a TMobile 4G image.
You then just have to disable the Cell Standby process by renaming two of the key .apk files.
I used another tool to replace the TMobile boot animation after rooting it, and removed the TMobile apps.

Thanks for this.
I'm actually giving up on the Streak. The screen just isn't up to snuff.
I think I'm going to pick up a Nook Color and play around with it.

No problem man. This device works perfectly for my application but I cannot recommend it as a general use tablet based on the screen.
I use it docked in the center console of my car through a custom fabbed mount based on the multimedia dock. Screen looks good on my desk when docked.
I personally think that they mounted the panel upside-down. If you are in an application that will rotate, just flipping the thing in landscape mode 180 degrees mitigates all the screen issues with having it on a desk.
The cheaper dell monitors suffer the same color drop off from below in landscape mode but most folks don't notice because most of the monitors sit on the desk at or below eye level.
I would have paid $50 more for a 1280x800 IPS version @ 8" or less.

The screen is fine except for a single angle. As a Galaxy Tab and iPad user, I can say without reservation that the screen issue is blown out of proportion. It's a budget screen, sure, but it's still as good as almost any laptop/netbook screen. The Galaxy Tab 10.1 it isn't, but it's a far cry from bad.

[Q] Can the Note be made to stop identifying as a tablet?

...if you know what I mean? Some apps work in tablet mode but I would like them to work in phone mode. For example FriendCaster Pro tries to squeeze loads of stuff into the screen but it looks fine on normal phone screens.
Cheers.

[Q] "reverse" accelerometer, or app problem?

Hello all!
I have been a proud user of Galaxy Note user for a bit over a week now, and I am trying to test (in real app-world) if all the sensors are working correctly to be able to bring change it at the store if something doesn't work, since I'm eager to root my device and I probably won't be able to return it then.
Yesterday I installed the game AirPenguin, which uses accelerometer controls, and it seems all messed up. Basically what happens is that as soon as the game starts, the bird goes flying way left, even though I am holding the phone still. What I found out after experimenting a bit was that the game itself is locked to portrait mode, but the accelerometer works as if it was in landscape. Meaning I have to hold it in landscape, and when I then tilt it left, the bird flies left in game-screen, but left is down from my point of view.
I was wondering if anyone else has seen such problem in this game or any other app, and if it is just a game bug or if there could be a problem with the accelerometer.
The stock accelerometer calibration works without a problem - when I tilt the phone left, the ball goes right, and when I tilt it right, it goes left (I suppose that's how it's supposed to be).
Thank you all in advance!

ME TOO
I'm facing the same problem on my Galaxy Note, I wonder if that happens also on other android devices or it's a galaxy note issue only?

i dont have the app, but is auto-rotate (that thing in the notification bar) turned off or on? try changing that to see if it fixes it?

Nexus and HTC Flyer, too any solutions?

Same problem with my Galaxy Tab 7+ P6200. I have encountered so many games in the google playstore with this problem. Too bad, i hope the app developers fix this problem for our devices.

afair there was a free app for comprehensive hardware testing, it was called Z-Device test, if stones interested, and google does not hello, I may try to find the link or apk later

MHL doesn't turn off the screen?

Hi
Any possibility for turning off the screen when I am using mhl tv out?
It doesn't makes sense that the screen it is on with the same image all the time.

How do you plan on doing stuff without using the screen? I can understand if you want to have it turned off during movies, but isn't it possible to turn the screen off and still get the image on the TV (when you're watching movies etc.)?

No, it isn possible.
If you turn the screen off, then the tv doens't play anything, thats because I ask.
For movies or flash on phone streaming to tv I don't want to have the screen on but I can't put it off and continue playing or I don't see how to do it

up ?

probably isnt possible, the same as with conencting a laptop to the tv via hdmi, the laptop cannot be shut and still plays the video

well i have a Blackberry Playbook + Galaxy Note, the playbook has an amazing option (would be great if they could put it in the Note) they have presentation mode for videos, u press it and then u can hit the off button, the screen will go off but the video will keep on playing

I am using Galaxy Note too. The reason why we need to turn off the Mobile Screen while playing movie, is because of the performance.
I read somewhere that the movie playing on TV is having bad performance because the phone has to render for 2 displays, hence it make the playback lags.
I bought MHL cable and it's really a waste that I can't have a smooth playback of movie...

I haven't tried it yet but maybe a combination of the TegraDisplaySelector.apk with chainfire3d will allow us to turn our screens off.

This widget app will give you the option to be able to switch between LCD and HDMI output, so you can preserver battery power, and disable any
annoying display enabled on lcd while using your TV.
you need to note, that managing the display is best with a mouse, but you can still use the disabled tablet screen for controlling your screen, but its not easy.
Remember you need to add this to your screen as a widget, thats the only way to access it, and it require root access to run the lcd vs. hdmi functionality. It does not work on android 3.x, as the library does not appear on that release for now

I get absolutely no lag on HD movie playing over MHL
but i agree that having both screens running is completely useless
when watching a movie

A little off-topic, but yes you can. Windows button + P will shut the computer screen off and only show the image on the TV.

nothing new?

Interested in a solution to this myself. Why burn the pixels when there is no need? Im a bit uneasy trying out the tegra solution presented above. I am heading to the play store to see what is available as far as presentation apps and such.

Wanted to bump this thread back up. Has anyond found a way to turn off or disable the phone screen while using the mhl hdmi out?
Like others mentioned its silly to have the phone screen on at the same time your watching a movie on a tv screen. There should at least be an option to disable phone screen while watching movie.

just did this to see that answer in ur notfications

No solutions yet? Would be nice if MHL mode could disable the phone screen for saving energy while improving HDMI video performance. I'd like to use my Galaxy Note as a netbook with external bluetooth mouse and keyboard, so keeping the phone screen on would be useless.

MHL does turn the screen off - but seems only while using built in player and playing a movie. At least it works like this on android 6 and Note 4. I am interested however in using KODI with the screen off while playing media...

[Q] What would make Google Cardboard rotate constantly?

I picked up a Google Cardboard for some fun, but the picture constantly rotates while trying to use it on my XZ. The axis of the rotation is that of going from portrait to landscape (Y axis??)
I've tested the accel, compass, and gyro using the service tests and they all seem to be fine. My XZ is completely stock and up-to-date (OTA).
Not sure what the problem could be? It works fine on my SGS5. I'd appreciate any feedback as the XZ looks and fits inside SO much cleaner than the SGS5, plus its not my daily driver so I won't have to take it out often.
I vaguely recall the same error happening on an app a long time ago, can't remember for the life of me what it was.

Hey. I also play with VR for almost month now(got two vr goggles with are WAY better lenses and quality than cardboard)
And also I have this problem of rotating screen. And to be honest its all depend on app and orientation provider. Most of the time app use indirect/direct sensor fusion but this method just suck...
I found only one solution for that and its to put phone on flat surface for few second with screen face up, and then phone calibrate sensor itself.
Of course its not helping for too long, but its always something...
My favorite VR game: Corridoom is best example for problem that we have.
Fast movement of device constantly move gyro starting point to one direction and when you sit in chair and look straight after a while you need to almost turn 180* because device lost this starting point. App does provide only simple calibration in main menu and Dev that I write about that said that for now its not gonna change this option.
So even if gyro in our xz is really accurate, because i use it as a VR goggles for PC gaming thanks to app Trinus VR
Only real solution for that is actual app that have option to block or reset roll effect. For example my main movie app for watching VR movies Cardboard Theater have such option and for most of time I dont have this problem when I watch movies.
I also tested it via service tests and you can see this problem, when you start app and this Rubik's cube is faced to you green move phone right and left and after few moves its not facing green, but red or blue... And for that app should have that option to reset yaw and roll when you stop moving, but for now most of devs that create VR apps and games just dont think to put such options.
And its not only XZ problem I tested it with galaxy S5 and galaxy Grand Prime and its also have that problem but not that often, mostly when I move my head very fast or for too long, screen start rotating.
maybe it would be possible to fix that in device it self to reset that roll effect but I dont think that anyone with knowledge would like to check that... :/

Trackers are pretty sensitive without some kind of reference point such as a camera. I expect a small amount of bias error over a duration, but using cardboard movie theater the screen turns 180 degrees (roll) in less than 10 seconds. The sensor tests are nowhere near as inaccurate.
Obviously any phone will have the issue over time though, they are cheap parts in small housing. There's multi thousand dollar systems with small degree of wander that are only IMUs. It's the severe amount the xz has that bugs me.
I'll try the laying it flat so it can reset its bias, might work. I noticed yesterday that when facing west it wasnt half as bad.
If you were actually able to enjoy a movie without locking the orientation then yours is far better than mine. My sgs5 I might have to adjust the orientation once every 30 minutes, the xz I have to reset it every seconds lmao.
Thank you for the input!
update:
Letting the bias adjust helped immensely. Thanks for the advice!

Hi did u manage to sort it out. I have xperia z and have same problem. I can play some games but everytime i use 'view in cardboard ' on youtube the screens spin, also when i use googke cardboard apps. Maby its a google problem and not our phones? Like you iv testedband recalibrated my phone byt to no avail
If you got it fixed giz a shout mate
Cheers
