Position sensor or something?

Ok, it seems there is a position sensor in TyTN (correct me if I'm wrong). When my phone is in its case on my belt and it's turned on (usually by a call), it's rotated (as if the keyboard's open). It takes too long time for it to rotate, and I can't answer the call until it rotates back to normal. So my question is, can this sensor be turned off, or is there other thing, that makes the screen to rotate and eventually how can I solve the problem? Thanks in advance.
P.S. I'm useing Schap's ROM, but the problem existed in the official rom, and the Black rom, and the official WM5 rom

no position sensor that I know of and I have never had this problem :s

Yeah, there is a position sensor on the hermes. It's a magnetic sensor that detects whether the keyboard is open or not.
The problem is most likely your case. I've heard of issues like yours. The magnetic snap on the case fools the hermes into thinking the keyboard is open.
I don't believe that there is a fix to bypass the sensor, as it is hardware. But I may be wrong. If not then you might need to look at another case that uses velcro or something.

ah now that would make sense, i never use that stupid case that comes with it, they are really ugly! so that would explain why i never noticed it.

My wife came up with a great solution when I had this poblem (standard case causing phone to start in landscape) - turn the phone the other way round! Now I have the screen facing my belt and the phone is ALWAYS in portrait when I get it out.
Sounds silly, but try it - it works!

Yep, that's a sollution, but there is one other detail. There's no other position I can plug the earphones .

Solution..... Bluetooth Headphones.

It appears to be a magnetic switch...
Your case must have a strong magnet on it, I can't get it to effect the switch if the phone is completely closed. Only if I have it partially open.

I have exactly the same problem. Also, my phone is NEVER put into standby before closing the keyboard.
I'm going to try storing it with the screen facing towards my belt.

I simply use Brando case and HTC BT S-100 headset. and never have a problem with phone starting in landscape.

FINALLY... WHAT YOU HAVE ALL BEEN WAITING FOR

I've come to notice that no one REALLY knew how to fully disable screen rotation on WM devices.
Some offered 3rd party apps to get the job done, some only knew how to disable automatic rotation, but when the device went into standby and woke up again - the screen rotated back. So that didnt really work.
So if you're as desperate as i was about screen rotation,
this is what you need to do:
1. Get dotfred's free taskmanager HERE, and run it.
2. Go to "Devices" tab, and look for "MIS1:" device (oem_misc.dll)
3. Long-Tap on it, and tap on "Stop"
4. Long-Tap on it again, and now choose "Set Manual"
5. Go to "Notifications" tab, and look for "Notifications\NamedEvents\VCPowerWakeupEvent"
6. Tap on it to make it selected
7. Disable it
(In dotfred's taskmanager, there should be a button for disabling it, but for some reason some devices couldn't see the button icons, although the buttons are still clickable. Under the notifications list there is an empty light-blue line - the buttons are there, eventough you can't see them.
The disable buttons is somewhere i the middle of that light-blue line, just tap the center until a message box popps up and asks if you'd like to disable this notification - Tap on yes.)​All those steps are a one time deal - they stick even after an SR.
This has been tested on htc universal and works great.
The screen will keep its orientation even if you flip your screen, take out your built in keyboard, or turn the device off and back on.
The only time your screen will revert back to the original orientation is when you soft reset your device.
Hope this helps

It's also the way to receive less radiation in your body, because the GSM antenna is pointing away from your waist.

I can, and I used a Tesla-meter to measure them:
in-between the two magnets of the case and the lid, there are around 150 mT (Millitesla) which is pretty much!
for comparison:
a usual horseshoe magnet would have 1 mT, the magnetic field of the earth has about 0,05 mT!

Desire always on speaker phone..

Hey , I have had my desire a few weeks now. I have a problem with it.
Every time i make a phone call or accept a phone call the phone will switch to speaker phone. This happens before i put the phone up to my ear so it is not my face that is turning on speaker phone. If i hold the phone in my hand and dial a number and press call, it goes to speaker phone. If the phone rings and i answer it, it will always go straight to speak phone.
Has anyone had this problem?

My guess: somehow your phone thinks it's charging/docking. Check your connector for dirt.

If nothing else helps you could try this app (actually a widget) in the Market:
Car Mode
With this you can turn the speaker phone mode on/off. Unless your phone has a hardware problem that forces it to be always on...

Don't bother before you flash to stock ROM/do a full wipe (factory reset). If none of those work, it's likely borked

Hi all !
I have been stuck for 2 weeks on this issue.
I have tried all those things :
- Switch off and then switch on the phone
- Remove and reinsert the battery
- Remove and reinsert the SIM Card
- Clean up the USB connector (and there were lots of dusts inside)
- Hard reset to the factory settings
Nothing has solved the problem.
BUT I have found a SOLUTION and also a process to see if you have the same problem as me :
1) Create a shortcut on your home screen and add this shortcut : Shortcut -> Parameter -> Car dock (the icon is a padlock)
2) Click on this shortcut and enable Auto start feature
3) A little car icon will appear in the status bar if there is a short circuit at that moment
4) Take your mini usb cable and plug it into the phone usb connector (without connecting the cable to an electrical outlet nor your PC, we don't want to charge the phone, in fact it doesn't matter but I advice you to not charge it during the process)
5) Now track if the car icon is present, if it is, just move up and down and left and right the cable to check if it's not a hardware short circuit like it is for me (!!). If the car icon appears and disappears during the process while you are moving the cable, then it's a hardware short circuit problem (nothing to do with some kind of software bug as mentioned by some people).
To fix the problem permanently you have 2 choices :
5.1) Take your phone back to the shop
5.2) My solution if you are a lazy man like I am : use the cable to twist correctly the male connector (the one inside the phone) to the correct position. For me the correct position was : lay down your phone on a table, screen upwards, you must twist the connector upwards too. The direction to twist the connector is from the bottom (the table) to the up (the screen) = If you take your phone in front of you and you are looking at the screen, twist the connector towards yourself.
I have fixed the problem this way.
I hope you will be able to fix it too.
Jérémy.

I ve got HDH and I ve instaled 'all call recorder' since then everithing was okay...but after 1-2 weeks this issue was happening speaker always on on recieving call or making a call.so my oppinion uninstal(if you have) call recorder app.it will fix this issue.cheers!

Boot image in landscape mode

I've seen the method on the Tab S forum of XDA developers for amending the boot image but nothing yet for the Tab S2 8.0 (SM-T7130. Is anyone working on this?
My objective is to use my Tab S2 as a 'head unit' in my car and have it boot up in landscape mode. I've already changed the bootsamsung.qmg and bootsamsungloop.qmg with my own files and they are working fine in landscape. However, I don't know how to amend the boot image. The instructions for the Tab S don't appear to work for this model. Well, they didn't for me.
I'd much appreciate a pointer in the right direction.

Hi,
I am trying to do the same thing as you, use it as a head unit. How is it working out for you so far? Any issues?
Thank you

Nothing yet - and I'm unable to devote any time to it at the moment. Good luck with your search for a solution.

Well, I am in the design phase right now, just ordered the tablet.
Getting the boot logo in landscape mode is the least of my concern, I am more concern about everything else, specially how the tablet integrate with the rest of the hardware

I can help with other stuff (than the boot logo 'problem') as I've set my TabS2 to provide a sort of Driver Information System (DIS) for my campervan.
Some of the changes I've made are as follows:
1. Auxiliary output from vehicle radio to 3.5mm jack on TabS2 so it can use the vehicle's excellent speakers. Bought the connector on the internet but some modern vehicles come with a connector fitted.
2. Fused electrical connection from 12V Cigar Lighter feed through 12V-to-USB (5V) mini-connector (also bought on internet) to TabS2.
3. Wifi reversing camera (GoVue RVS-020813) connected to reversing light 12V power feed. (Wifi because I didn't want to hardwire through the vehicle).
4. Created a slide-in frame on dashboard using plastic name holders, with draught-excluder tape behind to hold TabS2 off vibrating stuff.
5. Rooted the TabS2.
6. System/bin/lpm file moved sideways and replaced with one that contains
#!/system/bin/sh
su
/system/bin/reboot
which forces the TabS2 to boot when power is applied (via mini-USB connector). ie. when the vehicle is switched on and power then goes to the 12V cigar-lighter circuit and also the spur connection via the 12V-to-USB connector to the TabS2.
7. Replaced the boot animation (not boot logo) with my own animation in landscape. For which I used Samsung Theme Designer (look on Youtube for how to do this).
8. Enforced landscape mode (for post-boot animation) using the 'Set Orientation' app for those applications I have that are otherwise restricted to portrait mode (the inbuilt portrait/landscape setting doesn't work for these).
9. Bought/installed 'Sygic for Truck' navigation app.
10. Installed 'Govue' app to use with reversing camera.
11. Using 'Cronoid' app got it to fire up Sygic on boot.
12. Using 'Automagic' (premium) created flow to check for reversing camera (ie. when actually reversing vehicle, reversing camera gets power and Govue wifi pops up. This daemon checks for it). When it is detected the Govue app fires up to display the picture. This flow also checks for when vehicle stops reversing (forward gear or neutral selected); it then kills the Govue app and displays Sygic navigation.
13. To ensure everything could be controlled via the screen (a bit difficult getting to the buttons on the edges when you're driving along), I downloaded one-touch 'ScreenOff' and 'Power Off Click' icon apps for sleep and power-off, respectively. The 'Handy Soft Keys' app allows a touch at the top of the screen which will display icons to avoid using the physical buttons. The volume is easily controlled with swipe down from the top and moving the displayed slider as needed. (Note that the power cannot be switched off while there is power via the mini-USB connector, which also means that when it is being charged it will always be booted up).
The Tab S2 is a very good bit of kit. The reason for the sliding method of attachment is because it is far too useful to devote entirely to 'Head unit' duties. I use it as my everyday slate (it also means it isn't on show to potential thieves when I park up).
Was all the above necessary. It's a moot point. I enjoyed doing it. At that time I was able to spend the hours researching the techniques on the internet.
Hope this gives you some ideas.

Nice!!!
Looks like you got everything figure out, thank you for all the tips, will sure come in handy when I start the install.
I went to Best Buy to get the S2, but saw the Tab A right next to it. I finally decided to get the Tab A 10.1 inches (2016 version) which has an octacore cpu and 2gb ram/16gb rom. Unlike you I plan to use this solely in my car, so I am planning a permanent install. My dash has a big opening, so the 10.1 inch will fit nicely, I am planning to fabricate a custom bezel to mold the tab case into a metra stock bezel, might be a tight fit, but I want it to look factory when done. I have a 2015 nissan murano.
As far as the sound, I was planning on using a usb dac, since now marshmallow support usb sound, but now that you mention it, I might just use the 3.5mm jack to feed my clarion eqs755 which is then connected to my kenwood amp. This will save me from buying a DAC.
How is the sound from the 3.5mm jack compared to the usb sound with a DAC?
What are you using for bluetooth?
The wireless backup camera is a good idea, will do the same. I thought that the camera will open the app once it detects power (by you shifting to reverse), no additional app is required?
I did not want to root mine, but looks like I need to, since that is the only way to be able to use the usb port for data and charge the tablet at the same time.
I also plan to use my steering wheel connectors to control the tablet (vol+/vol-, ok google, switching between app, etc...)
Will let you know as I progress...
Would be nice to see some pics of your install.
Here are the components I bought so far:
These will allow me to tab into my existing speakers, since I added a amp:

To connect tablet to eq:
https://www.amazon.com/gp/product/B00DI89NPE/ref=ox_sc_act_title_10?ie=UTF8&psc=1&smid=AQJ30SX0INWVM
I plan to use this for the bluetooth, will connect it to my eq using an rca splitter, for hands free call and bluetooth streaming from phone:
https://www.amazon.com/dp/B0168GBMC...TF8&colid=218K2YEKLKIR3&coliid=I3IWHA254QICIF
I installed Tablet Talk to get my calls and text messages forwarded to the tablet. When I get a call I can answer from the tablet, but the sound will use my Bluetooth.
I wanted to use samsung own SideSync app, since I also have a samsung note 4 phone, for hands free calls, but it only works when connected to the same WIFI network. Tablet Talk works with WIFI/Hotspot and bluetooth.
https://www.amazon.com/dp/B0168GBMC...TF8&colid=218K2YEKLKIR3&coliid=I3IWHA254QICIF

How did you get the Tab S2 to boot on power EXACTLY? I've been trying for DAYS and i can't seem to get it to work. It's rooted and everything, tried altering the lpm file and it just shows the grey battery icon each time.

I blame the youth

What a difference a day makes. Yesterday my rad new Xtrons Android headunit was working almost* fine and today, after following conventional wisdom and letting my 15yo nephew pimp it, it's in all sorts of...well fckd.
Keen on some help from the collective wisdom. Before anyone helpfully suggests a factory reset... well, that's been done, sooo many times. When your nephew CHANGES the factory settings, it becomes a cycle of hell.
Unit is an Xtrons PB86MTVP. 8" HD, Android 6.0' Octa-Core 64bit 32GB.
Current main problem is that the touch screen inputs are reverse and diagonally opposed. What the hell do I mean by that? If I want to type on the qwerty keyboard or simply tap an icon, I have to use my cunning and hit an area or button diagonal and opposite for it to work. If I can get past this issue then maybe I can move to the next one which is that the unit doesnt power on/off with the ignition.
To be clear, things tried (multiple times in some cases) include
Reset via reset button
reset via software app section
undoing car battery
pulling unit back out and disconnecting
turning on and off again
swearing
So, who can help? got a silver bullet?
TIA
Joe

You could go to settings start right down the line set your home screen back and you should have a setting there for different keyboards also that should get yoy back to normal

thanks for the reply djkeylenux. I've got the right keyboard though, thats not the problem. the problem is the touch input on the screen, no matter which screen I'm on.

Well beside calibrate witch I thing you tried you could also go to developer options take a kook at running process see if there's something running causing the problem,

I think you lost the MCU settings.
Go to settings and then into Factory Settings menu. Password is 126.
Then in keys tab re-calibrate the screen. During calibration you will first see a "+1" in one of the corners. Tap it with your finger. Then in opposite corner "+2" will appear. Tap it too. Then accept and apply ypir settings and the unit will reboot. The touchscreen will work correctly then
In the same screen you can also re-configure the touch buttons and physical buttons of yoir device.
It looks like someone potentially did an MCU upgrade/flash. If there was no backup of the settings then you lost it all. Which also means you might have lost bluetooth connectivity as the bt module type on first page of factory setting might be wrong too. Also canbus and other things might be affected. I recpmmend to check out the discussion threads on MTCD devices here. Someone with the same unit might tell you the right settings.
Hint: If you have trouble tapping the icons with non-calibrated screen. Try connecting a standard USB mouse to any of the USB ports.

Screen Mirroring problem

Hi guys, why I can't see the button top right to enable wireless display?

Noticed that as well when swiping down and not finding the wifi or bt icons to enable them. I also noticed that when i plugged the phone on t o charge the charging icon in the battery displayed that it was charging. Then when i went to pull down the USB connecting options drop down menu it wasnt there. Then once it did appear it was on the last option i used "transfering pics" instead of defaulting to "charging" like every other phone ive ever owned.

How can I fix it?

Wireless display is not officially supported by Google, so you won't find it in our phone. The only option is Google Cast (to Chromecast).
