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:

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.
When putting my device on wireless charger I get ui as shown in fotographs added.
Unfortunatly this ui shows up too, when I put it in my wireless charging car dock. Due to vibritations etc while driving, it shows up very often and overlays running apps like navigation, which is very anoying if you miss turns.
Thats why I am searching for a way to temporarily dissable (toggle on/off) this ui
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).

do you have root access if yes there's some props you have to add it to build prop
let me know if your phone rooted
Hello,
I have a rooted ( Magisk-v14.5 ) OnePlus 5t with Android 7.1.1.
Without me ( knowingly ) changing any settings suddenly the following behaviour occurs:
While I am typing in an App like Tinder, E-Mail etc... the virtual keyboard keeps sliding down like i touch the little triangle button on the left bottom corner. But of course I am not accidentally touching it.
Sometimes the Keyboard is sliding down without me even touching the phone.
This behavior seems rather random, sometimes it works for hours ... sometimes I can hardly type anything.
For me it looks like some "App / Process / Command " is trying to take over the input controls of the phone but it never shows up
I use the most updated version of "Gboard"
I tried the following:
1. de-install "Gboard" and use other keyboards like "SwiftKey Keyboard"
2. changing all settings the I somehow would relate to keyboard inputs
3. I used the " developer options -> input -> Show taps / Pointer Location " to check if maybe my touchscreen sensors are broken and the phone actually registers an touch at the point where the little triangle button on the left bottom corner of the keyboard is. => No touch registered
Can someone help me or has similar experiences and a solution ?
Just got my XZ2C two days ago and I cant find a solution to one problem:
How can I disable this "ambient display" lockscreen, which additionally is "over my lock screen".
I want to directly see the content of a new message via notification when I receive it.
Now with the XZ2C, the phone lights up and I have this black screen with a clock and a small new notification icon. (I guess this is called the ambient display?)
I then have to double tap the screen to be brought to the lock screen, where I then can see a notification with the message content...
I was not able to find a solution for this online.
Can anyone help?

Note, this hasn't devolved to the H8314 yet. Perhaps next update. It doesn't appear to be in 52.0.A.11.32 which has the 11/1/19 security update.

If you're referring to the 'Ambient Mode"....
I have the Sony H8314 XZ2 compact - Verizon-USA (with Nov21 security update 52.0.A.11.32) and I do indeed have it on my phone. It's accessed thru the Google account. You can get to it via the Android Google app\(…more)\Settings\Google Assistant\Assistant\Phone or thru home-screen\right swipe\Google account icon (top right)\Settings\Google Assistant\Assistant\Phone. It might be a server-side thing still rolling out. idunno.
Note: I've tried it and it works and is nice and all, but I've turned it back off b/c I thought it might interfere with the 'Battery Care' function. No info/evidence of a problem, just makes sense that it might preclude Battery Care from doing its purpose. I mostly charge overnight anyway so no real need to use phone when charging.

[update] Took a few days, but apparently within the last 48 hours it has become available on my H8314, too. I think it might have been bundled in a Carrier Services update, which also enabled RCS on Verizon handsets.

Sadly, this does not help.
That is also the first settings category I checked and tried to use, to disable that "feature".
Problem: e.g.: If I get a new WhatsApp message,
- the phone screen turns on, shows a black screen with:
- a clock
- a message icon for a new message notification in the middle
I would prefer to:
- the phone screen turns on, with my normal lockscreen picture
- a notification is shown, which also shows me (part of) the message content.
If I remember correctly, this was the behaviour with my previous XZ1 compact

Ok so I tried turning off my 'ambient display' and I get the same result as you, namely a new message icon appears on an ambient screen....even tho the ambient screen is turned off and without picking it up(which is what normally activates the ambient screen). So a bug is there in the coding I guess. If you turn off the 'wake screen for new notifications' then you get a blank screen with a blinking light at top left.
You can get your lockscreen pic to show with a text preview if you press the power button or do the double tap.
Hope this helps.

I thought all of this (how and where notifications appear for WhatsApp) are controlled from Settings->Apps & Notifications->WhatsApp->Notifications.
