[Q] How to calibration the accelerometer..?

My TF101 the sensor not balance , how to fix the problem..?

I've got the same issue and there s no way to calibrate the sensor !!!
I tried to hard reset the device : no joy
I tried calibrating with gps status, it only works in gps status, in all other applications, sensor is faulty !!!!

Same here! Don't know if this is since the 3.1 update (updated after 1 hour ownership of the TF )

I am experiencing the same issue...It's super sensitive.
Issue was there before update as well...
Sent from my HTC Vision using XDA Premium App

It also feels a little too sensitive indeed, but the biggest problem is the calibration:

I had mine changed today, it's far better but still choppy and inaccurate.
I would say on 3 degrees discrepancy, instead of 10 degrees on the previous one
Look at the first one :
In every case our g sensors are responding well, it's just a matter of calibration, I hope ASUS will releanse soon a calibration tool. Or maybe someone else.....
Is there a place where we can post some suggestions to ASUS ?

The calibration is done the same way for every android device, wave it in a figure 8 on the x axis, this will calibrate both the compas and the accelerometer.

I have contacted Asus, and the issue, including a link to this topic, is being forwarded to the Asus HQ. Currently there is no calibration tool available. I hope Asus can fix the issue soon.
As stated, calibration using the app GPS status don't have any effect on the tf (maybe not honeycomb compatible for altering sensor values?).

I too think mine is off by about 3 degrees.
Interested parties can grab the MyBeer live wallpaper here.

thankfully that's one weird thing mine doesn't do...3.1 here also.

I had this same problem with my phone. The solution was to spin it rapidly several times on all three axes. Worked like a charm.
Unfortunately, this is a lot easier with a phone than a 10" tablet ...

I wrote ASUS about it and they answered there was a calibration option in the Display parameters menu.
Thts where it s supposed to be i agree, but it s not there.
They don t even know their product.
They don t even check before answering, we re not blind.....if we say it s not ther, that's because it's not there.
I found the solution : i returned mine back to the store and had one well calibrated now. not perfectly but that's far better.
I suggest you all do the same and maybe then, they will check and notice the option is not here !!!

Once rooted with Prime or another rom, is it possible to calibrate the accelerometer with the "sensorcalibutil_yamaha" command, as mine seems to have a slight problem as well ?

I tried on my root TF and it doesn't work.
the calibration file accessible is "sensors-config" but I failed to run it in order to calibrate the tablet

Mine is fine. But for some games and apps it's off.

@ThaiM : the animated wallpaper with the ice is also perfectly horizontal for you ?

I'm using the Lochness Monster one. Yes, docked on my desktop, it's perfectly level. Only in some games and apps do I notice that it may be off. But I think that's because of the angle of the device I have it on while I start that program.
Maybe try that?
Make sure you're level, and reboot. Let me know! Maybe it calibrates on startup?

Good idea, but I rebooted in a perfect horizontal position and the problem is still there.

I sent my tf to Asus RMA, due to left speaker problem and accelerometer. The status was 'waiting' for some time and asked what it was waiting for. Asus told me that it was currently waiting for a new speaker AND accelerometer. Unlikely, but maybe this is also a HW issue
DHL is now under its way, hope to see a perfectly working tf with calibrated accelerometer tonight

...
I have the same problem, and there is about 10 degrees rotation in accelerator, I hope that the developer solve it as soon as it is possible, it takes too much time if we wait for Asus supports!

[Q] Changed the main flex ribbon cable and its panel, touch screen error.

Hi,
My wifi and bt modules didn't work for the past two months, and after searching trough the Q&A forums, I came to the conclusion that I have to change the ribbon cable, perhaps thats the problem.
So, I've ordered the panel, and it arrived yesterday, it was this piece:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I've swapped it with the old panel, phone fired up nicely, I even saw the BT connections logo appear on the status bar. Yay.
But.
The touch screen doesn't register my touches anywhere on the screen. I've checked the connections, everything connects good.
I've dismissed the idea of a faulty digitizer, since before the ribbon cable/panel switch, everything was working as it's supposed to be.
I'm fully out of ideas, so I'm doing these steps as a last resort: (I'm currently at the third step)
1. Discharge the phone all the way (until it shuts down).
2. Remove the battery and press the power button (as if you were trying to turn the phone on).
3. Leave the phone without the battery overnight (or for at least an hour).
4. Put the battery back and charge the phone without touching the screen.
Make sure you don't touch the screen whenever you're charging, until the issue disappears. This should happen within 2-3 days. If the problem persists, you ether did something wrong, or (as explained above) you have a different issue... Most common related problem is a faulty digitizer.

If this fails, the last option I see could be this: http://forum.xda-developers.com/showthread.php?t=1360638 (thank god I have a backup)
Please note, that I've tried the responsiveness of the screen with both with and without the battery cover installed, so I've dismissed the little silver pin as the issue. And as I said the touch screen was fully working before the cable/ribbon swap. Touch doesn't even work in recovery.
So (after a long intro), my question would be, does anyone have any ideas, what could be wrong? TBH, I don't want to buy a new digitizer (even if thats the issue), because I don't want to spend any more $ on this phone (bought a new battery, battery door, some misc stuff)
PS:
I haven't changed anything software/firmware wise during/before/after the swap.
Current setup is:
ROM: latest android1234567 CM11
Kernel: Sultans r53, slight undervolt, slight underclock
Recovery: TWRP
S-OFF
Thanks in advance!

Auto-rotation not working

Hello, everyone!
Yesterday I discovered that my device doesn't detect its own orientation. It was after I tried to record a video and it came out vertical. I thought it was a ROM bug (since I was using the CyanogenMod nightlies), but I flashed with RSD Lite (cleanly) both 5.0.1 and the latest 6.0 ROMs and it still doesn't work. Sensor apps detect changes in the numbers when I move the device, though. I haven't dropped my Moto MAXX, and I always use it with a case...
Is there any way to recalibrate the sensors or something? I can provide any information or log if you tell me how to grab them.
Thanks!

Okay, this is REALLY weird. After a whole afternoon believing it was something software-related, I gently hit my device against the table three or four times and now it rotates correctly...

I was kind of desperate about the matter, probably I would have gone with the hammer option if the table hits hadn't worked.
By the way, and following my original post, is the gyroscope a mechanical thing? Or is it electrical?

It's the accelerometer.
Here's an issue Samung had with the Galaxy S6 at launch a year ago:
Samsung confirms screen-rotation problem with some Galaxy S6 Edge phones
http://www.computerworld.com/articl...-problem-with-some-galaxy-s6-edge-phones.html
Some Edge users have raised various theories about what causes the problem. One theory is that Samsung's fast-charging cord fried the chip that controls the accelerometer sensor, which affects rotation of images on the display. Another theory is that certain apps on the Edge — either third-party or pre-installed apps — have not been updated sufficiently to be compatible with recent minor Android OS updates. That lack of compatibility could somehow restrict the software controlling auto-rotation.
A Samsung technician on the 800-support line told Computerworld that users affected by the auto-rotate problem are being asked to test the faulty device by first going to "safe mode" to allow the phone to operate without third-party apps loaded by the user. If the problem persists after that test, the users are then asked to try a "hard key re-set" of the phone, which basically wipes all personal data and contacts and initiates a factory reset upon a reboot of the phone. The technician said personal data can first be stored to a remote backup location through the Samsung Kies or Samsung Smart Switch applications.
The technician didn't indicate what Samsung might do if the hard key re-set fails to fix the auto-rotate problem. A Samsung tech will walk users through the various steps required to perform the tests or Samsung can do the tests remotely.
The Samsung technician's course of action seems to indicate the problem is related to incompatible software, not hardware, but Samsung is not saying officially what the cause or the solution may be.
An Edge user named "IDOG" reported early Wednesday at Android Forums that he may have found the culprit. He said the rotation problem occurred when using the third-party Nova Launcher, but not when using TouchWiz, which is Samsung's own front-end touch interface. Nova Launcher, a third-party Android app by TeslaCoil Software, replaces a user's home screen with one that is customizable.
IDOG said Nova Launcher has so far worked fine after he uninstalled it and then re-installed it without borrowing any of the settings from his prior install of the launcher.
As a result of IDOG's field work, in theory, something as seemingly insignificant as user settings inside a third-party app could be part of Samsung's problem with some Edge screens not rotating properly

None of those seems to fit with what happened. Well, let's hope it stays functional. Thanks.

Nexus 5 freezing, screen acting up, camera unresponsive, WiFi stuck on 'turning on'?

Hi all, new member here, so apologies for any mistakes I make.
A friend of mine has passed on to me his Nexus 5 (2013), stating that there were a number of issues he was having with it. After using the device myself for a couple days I can confirm that the following issues are present:
- The screen will sporadically freeze and become unresponsive to any touch input, and the only way to solve this is to lock the device and unlock it again. The time between instances of this is random.
- The screen will occasionally cut to black, but the display is still active (i.e. you can only see the backlight). This happens for a number of seconds before returning to normal on it's own.
- The camera is completely unresponsive/broken (See picture 1 below). Possible loose connection?
- The WiFi is stuck on 'turning WiFi on' in the settings, and stuck at searching for networks in the notification bar(See pictures 2 & 3 below).
The device was dropped at some point in the past, but the damage is typical (See picture 4 below) and I see no immediate reason why this damage should cause these issues in particular, but I'm by no means an expert, hence why I'm here. =) The device has only been dropped one time, and has not suffered any other damage, including water damage.
My first instinct was to boot into recovery mode (where it should be noted that the freezing and display issues I mentioned above didn't occur, leading me to believe it is more of a software issue?) and clear the cache partition, which did not solve the issue, and neither did a full factory reset.
So, with all that being said, what would you guys suggest? Should I try flashing the factory image to see if that works? Rooting? Flashing a custom ROM? Any suggestions would be most appreciated!
If you require any additional information let me know and I'll happily oblige.
Thanks in advance guys!

It could be the motherboard or screen. You won't know for sure until you replace one or the other.
The wifi chips do fail on the Nexus 5. I a motherboard that also tries to turn on wifi but turns itself off after a few minutes.

My first thought was that it was a hardware issue to begin with, but due to the sporadic nature of the issues (excluding the camera obviously), and the fact that it didn't happen whilst in the recovery menu, I'm more inclined to believe it to be a software issue? I could be wrong of course, I'm just wondering if it's worth flashing the factory image on to see if that solves the issue?

You may as well flash the stock image and see what happens.
The lines showing on the screen does not look like a software issue to me.

Those lines are what appear when I open the camera, they're not there otherwise. THAT is almost definitely a hardware issue, granted.

I have a Nexus 5 that has the wifi issue. I flashed a bunch of different Android versions (like Android 7 and 6.0) which none have worked. At one point I opened my Nexus 5 and left it like that for about a month, then afterwards I assembled it back together and the wifi worked for a little bit and then went back to its broken state. I've concluded that it is a hardware issue since data was working fine and was the only way I could get internet on my phone.

Hmm. I have to be be honest after looking online it appears that wifi failure is a somewhat common issue on the Nexus 5 devices. It has to be a hardware based problem it would seem.
Thanks for letting me know, I appreciate your input. =)

Note 10 Lite's screen stops working after some time

I've had a Galaxy Note 10 Lite for some time now and it started displaying this behaviour where the screen stops working after some time of the phone being on.
There's no apparent connection to how hot the phone is.
I've also re-sat all the straps and cables and cleaned them with isopropyl alcohol.
Sometimes during use, I'll see some quick greenish/purple-ish glitches on the screen. But, apart from that, it'll look amazing the whole time.
Also, sometimes, as I use it, the screen will freeze during whatever is happening on the screen and the image will refresh if I press it down on the 2/4 area from the top down.
Then, if I leave the phone for a few minutes with the screen either on or off, I could come back to it being unresponsive. At first, I thought it was turning off. But if I press the screenshot buttons, it'll vibrate and save the screenshot that I'll be able to see after I soft reset the phone back to life (it'll reboot by itself from time to time, though).
The time it takes for it to "die" varies from seconds to minutes to hours. But it's become unreliable and had to buy a new phone.
I thought about replacing the screen, but it costs as much as a new phone here in Brazil.
What I'm thinking is maybe there's some cable or something I could access on the screen to inhibit this behaviour.
Can anyone help me out with insights?
Cheers,
Uriel

Try in safe mode.
Clear system cache.
Try a hard reboot.
Any uncased drops or water exposure?

Just tried safe mode and the screen started all messed up, with elements that should be organised scattered all over it.
Now... I'm soft rebooting it and it goes straight to a dark screen after showing the Samsung logo.
I was going to try clearing the cache next, but now I need to get access back to the system.
I've done a hard reboot to no avail.
It was exposed to water years ago, which resulted on a screen issue that was fixed by Samsung by replacing it.

Ok. I got safe mode successfully activated now. I'll give it time but I don't feel too optimistic about it.

May have water damaged ribbon cable contacts, or water damage on the mobo is now showing up; corrosion never sleeps. Maybe another display failure. Maybe a loose cable; carefully inspect all display cables on both ends and their sockets. A failed ribbon cable.
Finally a corrupted rom or user data partition.
These phones are relatively inexpensive now, even new ones can still be had. The N10+ be an upgrade if you like it. If repair doesn't work you have other options.
The newer Samsung's suck. This generation of Notes was the zenith for Samsung and the Note... in my opinion. I have two N10+'s and they run like bats out of hell. Solid, well built, work horses that just keep running. This one in my hand has over 8k hours on it, looks, feels and runs like it's new with one battery replacement. Zero display flaws, current load is over 2 yo, still fast and stable with minimal maintenance. That's what these phones are capable of.

Never know, could be a 3rd party app.

So, this happened. And it rebooted right after I stopped recording.

Yeah looks like the display but you won't know what it is without opening it up.
Don't think a factory reset or reflash will help... I could be wrong.

Yep. I'm pretty sure it's a hardware issue.
I don't know how to get access to the other end of the ribbons that go into the screen, though. I'll see what I can do.

Watch some tear down vids. Have the right tools and take your time. With used ones going for a couple hundred that's another option.
I'm surprised how well my N10+ has held up, it's always cased. Water exposure is a killer. Even if it's IP68 rated, keep it away from water, especially salt water.

I hope is the backlight issue on the logic board
