[Q] Nexus 7 sensor coordinate system orientation? 90 degree offset like tablets? - Nexus 7 Q&A, Help & Troubleshooting

Anyone who's had an Android tablet knows that a lot of poorly coded apps get flummoxed by the default 90 degree rotated, landscape orientation of the device.
Thus my question, is the sensor in the Nexus 7 rotated as well? Or is the default orientation set to portrait, the same as a phone?
Google "sensors-overview sensors-coords android" to find the relevant developer page. The specific orientation details are near the bottom: Sensor Coordinate System
"One Screen Turn Deserves Another" is an excellent article that explains the problem quite well.
If anyone who has a preview device could check to see what orientation the N7 uses, that'd be great. I'm hoping for portrait.

I'd assume it would be rotated since they're very intent on educating users on using a 7" tablet in portrait like a book.

Yea I'm gonna say that it's probably not in landscape since the whole UI is portrait based. Seems a bit counter productive to have to rotate the device every time you launch an app.

I'm fairly confident the sensors will be in portrait orientation by default, but confirmation would be nice.
The reason I ask is because my current Galaxy Tab 2 7.0 has the 90 degree offset sensor issue. 99% of the time it's fine. It boots up in portrait, apps launch in portrait (unless landscape only apps, which launch in landscape with no issues). Certain apps that are poorly coded and expect all devices to be portrait by default tend to do all sorts of odd things though. I've only run across a couple in the Play store, and one of those has been fixed.
The real problem lies with custom roms, as all of the ones I have tried default to the landscape sensor orientation (boot orientation when laid flat is landscape), rather than compensate for it (the stock Samsung rom is portrait by default when laid flat). This has led to all sorts of aggravating (and unintentionally hilarious) issues with the custom roms.
So hopefully Google thought this through and the N7 sensor orientation is portrait by default and basically acts like a large phone minus the phone bits.

[Q] Screen Rotate 180

Hi,
Does anyone know if there is a way to rotate the screen from the normal portrait view by 180 degrees?
I am using my Note with a bottom hinged Noreve case (which I love) and this rotation would allow me to use the case as a stand?
Thanks
Even if there is this possibility, consider this: several times you'll answer the phone in the dark and wonder why that asshole in the other side isn't saying anything for the third time, then you realize the phone was upside down. That happened a lot with me and my old Atrix =p

i dont think the stock touchwiz will rotate but apps should rotate if you have enabled it and the app supports it

Landscape vs portrait mode inc. keyboard & rotation

I actually started using Android for the first time with ICS Elite ROM coming from a blackberry and didn't realise that some launchers do landscape mode.
As a result I've been using my i9000 locked in portrait mode to type and everything. The new ICS keyboard makes this feasible.
The thing is, I don't fancy doing a .zip unpack again even though Nandroid backup and Titanium backup is fairly easy. Is there a launcher to install that can do it or would I then find more apps that don't work so great in landscape? I don't like turning the screen all the time and also because if you lay on your side the auto turning is annoying, yet that's the only slick way to use both screen modes.
If I can find a launcher that can do it, it might be better to use landscape all the time.
Is there anyone else out there who uses exclusively portrait mode like I currently do?
"go launcher" has the option to either lock it in one position or turn with the sensor. some widgets get a bit distorted in landscape though

[Q] Nexus 7 homescreen-does it rotate?

Does the stock nexus 7 home screen rotate like a regular android tab into landscape or portrait, if not then i will need to get a launcher to remedy that problem. Does anybody know if that could be changed to have the homescreen rotate, if it cannot?
It does rotate as usual.

I have gone through every video I could find on youtube and not one of them showed the tablet with its home screen in landscape mode.
This review says it was clearly meant for portrait only because most apps dont rotate. I wonder if all the demo units just had auto rotate turned off?

Another review that says the home screen does not rotate.

There's an icon on the notification bar that locks the orientation to portrait or landscape or lets you have it free, most likely the presentation unit had it locked to portrait. Must say it would be weird as heck for a tablet to be made for portrait mode.
Also, awmagawd, the first review has a white version of the Nexus7, love it.

I have looked through many YouTube videos too and didnt notice it either, I hope with rooted, the home screen could rotate.
Wondering the same thing! I definitely hope it rotates...

I haven't seen any video showing landscape mode either. But soon enough custom launchers will be updated for JB and the problem will be solved. Nova and apex are updated quite frequently and I would assume they have plans to implement the new Jelly Bean features.
I've read reviewers who've stated that it does NOT rotate the home screens. I suppose they all could have missed the rotation lock, but it could easily be just for apps.

hopefully nova will update by the time that the things gets in all of our hands.

That's an APP rotating, people are talking about the 'launcher'...
I use my tablets in landscape more then portrait, so although I trust all rotatable apps will be fine, it's disjointing to go back to the launcher and have it 90 degrees out..
The Verge said,
One thing that struck me as odd, however, is the fact that the homescreen doesn’t have a landscape view. As in, you cannot turn the tablet to landscape when you’re on the homescreen. It’s actually a bit frustrating when you move from a landscape app back home — and I can’t figure out why Google would have removed this functionality, which was present in Honeycomb.
What I find mostly odd about not having a landscape launcher mode is the fact that the pins on the side for the to be released dock would allow the tablet to be docked in landscape! Perhaps there will be a separate dock launcher?

It will look a little silly sitting in the dock Asus announced today.
I have jellybean installed on my Galaxy Nexus and the homescreen rotates perfectly.
so i don't understand why it wouldn't rotate for them unless autorotate was off.
My TF does it but my Galaxy Nexus never has (and it doesn't on Jelly Bean either). I think it's one of the differences between 'phone mode' and 'tablet mode'.
3rd party hacks can enable homescreen rotating on ICS so it won't stay fixed for long.
Google wants n7 to be used in portrait on the home screen and it does not rotate idk why they did this but its something that can be changed by devs.

Gallery photo auto orientation incorrect...

On the Nexus 7 the gallery auto rotation of photo's is incorrect
i.e. landscape goes portrait and vice versa
They display fine on my Samsung Galaxy SII (source) and in the Google+ Photos from either any PC or the Galaxy SII
Is this a calibration issue? Or is there some other setting?
Cheers
David
Getting similar results
I am having this issue also. A portrait photo with the nexus held in portrait position auto rotates to fit across the screen in landscape view. This happens when auto rotate feature is both enabled and disabled. Any suggestions?
Exactly the same problem here. Photos taken on a Nexus S running Jelly Bean and uploaded via instant upload display in incorrect orientation (always over rotated by 90 degrees) in the Gallery on Nexus 7. They are in the correct orientation when viewed any other way including on the web via Picasa and on the Nexus 7 via 3rd party Picasa viewing apps. I really would prefer to use the stock Gallery app but this is so frustrating.....
Any solutions to this? Exact same issue and it is a real bother
very same problem here
If I take a landscape photo on my SGS II and have it "instant-uploaded", it will appear okay on my Nexus 7. If I take a portrait photo on the SGS2, the photo will appear in the right orientation for app. 0,1 sec, then gets rotated (falsely.) Then, if I email that falsely rotated photo to myself, the photo will appear in the email with correct orientation.
Btw in the Google Plus app both photos have the correct orientation, so it seems to be a Jelly Bean bug, not a Samsung bug.
Solution, anyone?
Same, but different....
I've got pretty much the same problem, but rather than actually rotating the picture so that it is in the wrong orientation, it keeps the correct orientation for portrait photos, but compresses them vertically into the same space that would be used for a landscape photo, thereby distorting the aspect ratio (hope that makes sense!). Same occurrences though, only in gallery, not G+, and only on this device and for portrait oriented photos uploaded via G+ instant upload.
It is driving me insane!
Same thing here except it doesn't do it to all the pics in my instant upload. Only some of them.
It's probably some Android bug as I have the same problem on my SGS2 with CM10 (JB). All photos look ok in the Gallery (although when I exit an opened portrait photo it turns 90 degree to the right in the animation. Very annoying as all portrait photos I post on G+ are wrongly oriented.
Galaxy S3 Same problem
Same problem with my Galaxy S3, i thought i was the only one with this problem, so its a relief to know I'm not the only one, its been months since this thread was created, and its still an ongoing problem, it would be nice to know if a fix is on the works, by the looks of it, it might be a bug with android not samsung, either way has anyone found a work around this?? or heard anything new on the issue

Buying advice & device impressions

Hoping to get feedback on user experience with the Mediapad M3. I have not seen a post for this and just purchased US m3 64GB - waiting on delivery.
It would be great to hear from you on the following:
- Are you pleased with the purchase?
- Country
- 32 or 64GB, LTE
- Stock or custom ROM
- Expanded storage size
- What you like most about the device.
- In reading through threads here, seems most everyone loves the hardware and build quality.
- Firmware updates have corrected issues seen early. Settings adjustments and launchers help too.
- 5ghz works if device is rooted and file tweaked
- Unlocking and rooting are possible but not as clean as we've seen with other devices. Untrusted screen popup on boot is annoying.
I will likely use stock and be hawkish for updates and would appreciate your insight.
Thanks in advance.
John
Just recently bought this and had it for an hour.
Compared to a couple of other tablets I own, I'm blown away by the sound quality so far (Its really loud..)
Located in USA 64GB on Stock rom latest update.
The main feature I look for in tablets is the expanded storage so it's a plus.
I like the size, weight wise it's not so bad, screen is bright indoors (Some people say it's not enough)
I'm saddened that this device isn't really popular, it doesn't have custom roms or kernels but I can make do with it with what ever it has. Besides that I have a OP3 power horse for anything else.
As the name suggest for this tablet it'll literally be only for media like books, manga, videos, and music(?).
You won't be disappointed and will be more eager to use it when it hits EMUI 5.0 and it's Nougat update :]

Thanks for the response! Great insight.
Did you get the firmware update when booted up or did you have to check for updates? I agree on Nougat and EM5. Come quick. ?
I have had Nexus devices since GNexus. Nexus 5, 7, 10, 6, 9 and 6p. Of these, the Nexus 9 had been the most disappointing by far performance wise. The sound is decent for movies and videos. However, been waiting for the right replacement and do hope this is it.
Thanks again.

It already had the update when I got it. Bought it used (like new) on Amazon. It's really snappy and kinda big for my small hands but a better keyboard fixed that right up. Using thumb keyboard and the layout fits very nicely when typing in either horizontal or vertically.
Performance wise you just need to switch it over to performance mode and you can forget about it being sluggish.
Have been looking at this as a replacement for my Samsung Galaxy Tab Pro 8.4 whose battery is slowly failing. The specs look great but the lack of development is kind of concerning, I love trying new roms on my android devices.
I've looked at the root and twrp threads and it looks like things have progressed to the point I can be confident of having a rooted device I can take nandroid backups of. As long as I can have root and put Action Launcher 3, TB, and the other basics on it I should be happy.
Now I just have to debate whether an extra $50 for the 64gb version is worth it considering I'm coming from a device with 16gb.

1. Yes. Very little traction on development. Would love to see this pick up.
2. Good progress on rooting. Wonder what the unlocked warning page looks like...but only want to see it once.
3. Action Launcher 3 is great & I will install even before rooting. I run Action 3 on my 6P.
4. Spend the $50 - you get a headset and twice the storage.
Mine arrives today. I will post feedback once I give it a spin. If the IMUI 5/Nougat beta program is open, I will register.
Too loud

It is loud indeed, unfortunately too loud for me. The lowest volume is the same as 50% on my Galaxy S6.
I've tried Fine Volume Control V2, which works great on my phone. But on the M3 you have to open the app itself to adjust the volume. Using the volume rockers resets the volume level.
Is there any other apps I can try? Thinking about returning it and wait for WMC.
Hi,
I'm also interested in buying this tablet, but I have some concerns:
1. I will be using the tablet 100% in landscape mode. Can I lock the rotation to landscape (*without* third party apps)?
2. In landscape mode, is the navbar to the right instead of bottom? Can it be changed to bottom in the settings?
3. I saw that it supports gestures on the fingerprint reader. Can the navbar be disabled in the settings, so only the gestures can be used? Can *both* be disabled (since the fingerprint reader is right where you hold it in landscape and it will get accidentally pressed) so I can use a third party pie control?
4. Is the lowest brightness low enough so you can use it at night without any problems (and *without* software filters)?
5. At the lowest brightness, does it flicker? Using a white background / picture, when you wave your hand / finger, is it continuous or "framed"? See https://m.youtube.com/watch?v=ru474L8N15w
6. Can all versions be rooted & TWRP installed, or only the US version? I will buy it in Europe. Can Xposed be installed?
Thanks.

This might not be the tablet for you if not rooted with ROM. Others may know differently but this is what I have found.
1. Landscape locking: if you use a launcher like Action 3, you can lock in landscape. However, this does not lock stock settings menu.
2. Landscape horizontal nav bar: no but you could turn them off. This is a phone OS with little thought of limiting phone centric features.
3. Disabling nav bar and finger print gestures: you can turn each off independently but not at the same time.
4. Brightness or dimming are fine. Low setting is low.
5. No flicker at lowest setting.
6. See the post of rooting devices. I think all can be rooted. Unsure about Xposed.
There's also a built in pie type control.
I pulled the trigger on the 64gb version today. It's $20 off at newegg this weekend and my son had given me a newegg gift card for xmas. Bought what looks like an ok case on amazon - will be looking to see if seidio/trident/otterbox come out with one in the future.
Now just have to wait for my new toy to arrive .

You are probably talking about the home screen orientation, which for most launchers is by default locked to portrait.
But are you saying that, if you hold it in landscape, the Android settings is still in portrait?

Correction: Actually, system settings display in landscape. I had the portrait screen orientation setting locked.
If you don't have security enabled, does touching the fingerprint sensor when the screen is off turn it on?

But can you lock the orientation to landscape? Or it behaves like a (giant) phone: either auto-rotate, or just portrait?

You can turn off the fingerprint ID so that it does not unlock and wake. However, the fingerprint touch pad continues to allow gestures once unlocked. I have not found a way to turn off security. I think I read you need to root before you can do this.

I'm not talking about the home screen (which is launcher dependent), but the "global" orientation.
For example, you're holding it in landscape with auto rotate on. Open Chrome. Swipe the notification shade, go to toggles, then toggle auto rotate off. Does Chrome remain in landscape, or it switches to portrait?

The button in the only has two options, auto rotate or portrait. So it locks both the homescreen and apps to portrait like lots of phones do.
Had the same problem with my old Galaxy Tab 7.7 and had to use an app to fix it.
