I have seen a tilt control device that you can use with some handhelds that emulates the iphones tilting display when you move it or turn it. Is there anything out there thats software based that detects motions through your camera and then changes the screen orientation? I know that Windows Mobile 7 will feature this. So just wondering if anyone beat MS to the punch...

I know this isn't exactly what you are looking for, but i remapped the PPT button to rotate the screen. Just search for the thread on here, I think I found it in the Tilt or Kaiser wiki, and use the buttons app under settings and set it to <rotate screen>. Works for me.
[Razer Phone 2 Questions & Answers] Gamesoul Master:
Just wondering if anybody else has experienced this. For me, specifically when playing Dissidia FF: Opera Omnia and one other game that I tried once but can't recall... When playing, sometimes the bottom speaker will not play sound at all or sound will play in "crackles" (as in, the game sound plays in crackle-length spurts). I can't find any particular cause for it, and messing with settings has done nothing.

Doesn't happen to me with watching videos, listening to music, or playing other games. But I'm wondering if it's somehow still something on my end, or if other people have experienced this. It doesn't happen constantly (sometimes the sound is just fine), but I'd say... Maybe 60% of my time spent playing, this issue occurs.
[Razer Phone 2 Questions & Answers] CurtisMJ:
This is indeed a known software issue on MR2 seemingly to do with low volume. Does briefly increasing and decreasing the volume make the problem go away for a while?
[Razer Phone 2 Questions & Answers] Gamesoul Master:
Hmm... Initially I had thought I tried that thoroughly enough. But I figured out a way to make the issue more repeatable, and I tried turning up the volume well past the halfway point (which is usually overkill on this phone... lol). Turns out the sound does indeed kick back in when the volume is put above halfway or so. Sorry, I didn't realize it had to go that high to realize what's going on.

It's still weird that it only seems to happen in this one game I play (and that one other random one). All my other games, music, and videos have no issues. Well, here's hoping they eventually fix it... lol.
[Razer Phone 2 Questions & Answers] thegregulator:
I had the same issue playing Clash Royale and Final Fantasy 7. Like you, turning it up to about 60% "fixed" the crackling. But it would return again eventually when I turned the volume back down. I ended up returning the phone because the Microsoft Store is an amazing place with 30 day returns. I love the phone so it sucks, but that issue is a real deal breaker. Once they get it fixed I'll look into getting another. On a side note; I did contact Razer support through twitter and they were going to send me an RMA. Had to go through the whole song and dance of "Did you try a hard reboot" and "Did you do a factory reset". If you decide to do an RMA and they say no let me know.

The image file, howe install boot or recovery with twrp
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Svirusx:
When you are in "Install Zip" and can choose zip in the bottom you can choose "Install Image". Than you need to choose Nethunter boot.img and choose in TWRP that is boot.img not recovery.img

After installing don't boot frezz directly on Superman Rom, work this with TGP Rom?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Svirusx:
I use Stock Oreo ROM with this kernel.

This kernel is made from Stock kernel source and inserted in Stock boot.img.

You could try some possibilities:

First try:

If you have encrypted data partition than try flash this kernel and then Magisk 18.1.

If you have unencrypted data partition than flash it than remove encryption.zip and than Magisk 18.1 (remove encryption.zip)

If you want yet trying than:

If it doesn't work maybe it could work if you extract kernel from boot.img and insert in your boot.img kernel but it can be complicated and no warrianty it going to working...

If you have soo much time for testing than but if you didn't used it before backup is recommended:

You can also try too Dualboot patcher and flash Stock ROM and then this kernel i tested S7 kernel first at second ROM before flash it on main ROM.

I have Galaxy s7 Flat so Flat version is tested by me this one i can't test :/

Need to know that
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Svirusx:
after flashing TWRP

1.flash G935F_Nethunter_StockOreo_v1.1.img

2.Install remove-encryption.zip (You don't need to install no-verity-opt-encrypt.zip its is in remove-encryption.zip and it may make errors or override settings from remove-encryption.zip)

3.Now Reboot to system (Without magisk because magisk corrupts remove-encryption if is installed without reboot to system and in effect of that you get encrypted data partition.)

4. after first configuration wizard reboot to TWRP and install magisk 16.1

If this doesn't help you than you can try WirusMOD version (Oreo Nethunter kernel based on TGPKernel)

1. Flash latest TWRP twrp-3.3.0-1+ ( to see data partition with enabled disk quota)

1. TWRP Backup your ROM

But when i copy and try to install G935F_Nethunter_StockOreo_v*.img from TWRP, it asks me where to flash this image. root or recovery partition. first time, i flashed on boot directory and i got a boot loop. then i recovered boot and flashed on recovery petition. then i got stuck on boot image. after that i recovered it from backup again.

so please tell me where to flash this G935F_Nethunter_StockOreo_v*.img file?

To let you know, i already rooted my s7edge (sm-g935f) (Exynos) With SuperSu and i did not have backup of my original ROM. I have installed TWRP and Rooted. Then which steps i need to follow now? I tried to remove SuperSu and install magisk but i could not. so i downloaded nethunter from nethunter app store.

I have Kali net hunter already installed but i want your karnel to support usb bluetooth devices and all other fixes you did. my current kernel is 3.18.19-19497658-QB34216502 #1 SMP PREEMPT.

Hello

hello @Svirusx

Is this still working or have installed it on custom ROM since then?

I'm with Pixel Experience (A11) right now but I'm interested in installing it on stock ROM (oreo). That's why I'm asking

Do you recommend rooting it or it doesn't make any difference using Kali Nethunter with a rooted/non-rooted phone?

Thank you for the guide!
[Android Head-Units] maricmilan:
It was not happening before, but recently, every time i turn on the key, head unit does full reebot sequence instead of turning on immediately whicht was the case before. It did full reboot, only if i did not turn the car for couple of days. Olso, sometimes when i turn key just one step - it turns on - and when i turn ignition on - it again goes to reboot cycle :( But recently, all the time it just does full reboot even I was not in car for couple of minutes :(

Is there ans solution/setting for this, what should i do? Its anoying waiting full cycle all the time :(
[Android Head-Units] surfer63:
There are only 2 possible reasons:

- Bad battery: It is winter and when starting your car your battery voltage drops too much thereby "under powering" your unit which causes a reboot.

- You installed an app that keeps a wake lock or you installed a badly written, badly behaving app. The screen switches off almost immediately. The android part of the unit is switched off after 4 minutes to do it "clean". If the unit detects after 20 minutes that it can't stop Android because some app "keeps it alive", the power is simply cut off to prevent that your car battery is drained in 2-3 days.

So check them both.
