Clicked Deny during a Samsung Dex install/connect and cant reverse option - Samsung Galaxy S9+ Questions & Answers

I know this is probably an easy fix but i cant find the USB options anywhere, or find any way to reverse the accidental tap on my phone. I was on a road trip and during the Dex install on my windows tablet while in the car, accidentally tapped the Deny connection on my phone. Now it wont connect to my main PC either for Dex and seems to be stuck in Charge Mode only for USB and the Developer options dont seem to have an effect. I dont have the drop down options in the main notifications tab anymore, i think one of the more recent updates killed those options.
Quick edit for clarification: I cant access any files over USB currently through windows, cant access Dex, or anything. Just charge.
Id like to back up all my current stuff before my new phone arrives so getting a data connection is pretty important...

[Q] Change/Fix ROM Settings/Menu Options via ADB

Hello,
Rather an unusual problem, i dont intentionally want to go the difficult ADB way, being the novice I am. However I cannot access a usual settings in my current favorite ROM, so I need a way to get to it.
I have been using this ROM on my S4 i9500. I am unable to find an option in the ROM for Day Dream. In other ROMs, when on the daydream setting screen, there is option via the menu button, to choose when the DayDream should work "While Charging" or "While Docked" on while on either of them.
In Ozcan 6.3 ROM we can only choose the daydream to be ON or OFF, the menu button does not work to let us choose the conditions for daydream.
In my case I have a Samsung multimedia dock which I normally use for charging as well. So when I dock the phone , it is recognized as "Docked" hence the daydream is never activated. Otherwise if I simply connect a charger to mobile, the daydream starts after a while.
So I need to know is there a way we can change this settings to be able to daydream also when the phone is DOCKED, it serves me well as being a bed side alarm clock.
I guess there should be a way to change this settings directly via the ROM settings files or via ADB. Only need your guidance and support to know how.
Hope I was able to explain my problem.
Thanks.

Galaxy S3 i-9300 Cracked screen + touch screen. Need to view call history or SMS.

I dropped my s3 and now it has a very thin crack on it. First I was able to see some colours but now it is only black - touch screen gave no response aswell. I was also lucky enough to get the battery out on the initial drop so now all I can do is turn the phone on with or without simcard and let it connect to Wi-Fi. There were no SD Cards aswell.
The phone is not rooted, it is just "stock" in every way.
Getting it repaired costs more than what I paid for it while buying it from a friend years ago so I'm not even considering to get it repaired, I will buy a new smart phone, probably a Galaxy Note 4 or 5. (I'm not sure but this info might be useful. My smart phone knowledge is not much but may be there is a way to fix my issue(that I am explaining below) with the use of a Galaxy Note - without disintegrating the new Note)
My problem is that I need to retrieve a phone number that I didn't have the chance to save yet at the time of the drop. The number is probably one of the latest 5 in Call History and there was also an SMS that came from that number - that specific SMS was saved on the phone, not the simcard.
Absolutely nothing happens on computer side(Windows 7 Ultimate) when I plug it via USB. Can't see the content of the phone in File Explorer or anything else. I updated drivers. The phone starts charging, though.
Samsung Kies does not work as it does not recognize the phone when connected via USB and I need to scan the QR Code to connect it via Wi-Fi which is impossible since I can not give any commands to the phone nor see anything but a black screen.
I have this Samsung Link program. It recognizes the phone through Wi-Fi and I can browse files in the phone from my computer. I checked all files, there is nothing SMS or Call History related. On my web searches, I found out that SMS messages are stored in "/data/data/com.android.providers.telephony/databeses/mmssms.db" but there are no such folders that start with "com.android.providers".
I did not have debugging or other things active at the time and I can not turn anything on or off. It only has Wi-Fi enabled.
I can't even turn the phone off except for pulling the battery out since I need to touch the shut down option that comes in the menu when you hold the power button on the side.
Is there a way to view my Call History or SMS messages from my computer? Please bear in mind that I can not install any apps or give any commands at all to my phone by the use of its screen and it is not recognized by the computer when it is connected via USB.
Most success I've had is the program called Samsung Link that allows my computer to connect to the phone by Wi-Fi and browse files, pictures, videos and such. (Also I did another check for both USB and Wi-Fi connections while typing these. USB still does not work)
I do not have access to another phone to swap screens-motherboards-whatnot.
Kind regards.

You won't be able to view the stuff you're looking for with a file manager on PC, Windows can only view the MTP portion of your sdcard, it cant access or view your system partition which is where mmssms.db is located. You will need to have the device rooted in order to retrieve the files you're after.
You can connect a USB mouse to your device and make selections using the mouse instead of touch, the tricky part is knowing where things are on the display to select them, you can use screenshots of the needed screens from another device like yours. If you can get it to connect to PC via VLC you can share the screen to your PC and navigate that way(you'll need root to access the folder you're after), if you can get it to screencast you can navigate that way also.
Regardless of whether you repair the screen or not, you will have to root the device to do what you're doing.

You can also try flashing a custom recovery(CWM if you can get it, what I'm talking about might not work with TWRP and if it did it would still be tricky). CWM can be used by the hardware keys to make selections where TWRP is touch which wouldn't work for you. With a CWM custom recovery you could make a backup of the device then copy the backup over to PC then extract everything you need. You could even root and flash TWRP then boot to TWRP and connect to adb and use adb to create a backup, there are instructions that are easy to find for creating backups with adb, just make sure you understand the instructions so that you're sure you're retrieving everything you need. Then extract what you need from the adb backup.
Maybe easier but more time consuming, contact your service provider and have them send you a copy of your call history, it should all the numbers you've called during the period of time that you ask them for.

OTG keyboard help / Accessing broken screen device

A coworker has a Galaxy Tab S2 with a broken screen. He also let the battery die, so fingerprint unlocking no longer works. I do have an OTG adapter so I can plug in an external keyboard to get the thing unlocked.
I'd really like to enable developer options, or at least allow USB file transfers (it's not enabled either). I've been testing on another device to try to make a walkthrough for myself, but it's proving to be a bit of a pain. Is there an OTG keyboard shortcut to launch settings or open the all apps folder?
He did buy an identical replacement tablet that arrives tomorrow, so I'll at least be able to attempt to operate them together each with their own OTG keyboard.
End goal is to enable debugging so I can take a full backup.

USB Settings

I have my USB Config set to MTP and USB Debugging ON under Developer Options. However, whenever I connect a USB device, it always resets itself to Charge only and I have to switch it back to File or Photo transfer in order to connect to PC, AA, etc.
Any ideas on how to make the USB setting 'stick' with what I set in DO?
Is there an ADB command? Other setting I should be looking for? Any help is appreciated.

Strange, I *know* that mine 'used to' stay at whatever setting it was left at before. I just tried it now, and it still stays on whatever it was last set to, BUT... It automatically toggles the 'allow debugging over USB' to OFF every time I plug my phone into my computer. Now I know it didn't do this before, I wonder if it has something to do with 'always trust this connection' being set? Also, it really seems like this stuff is behaving just a wee bit different since I unlocked my bootloader. Hmm, could it be they have set a flag where USB debugging always turns off when the device is connected to something, IF the bootloader is unlocked?

I can confirm that this happens on mine too, really annoying, but I think this is not something a lot of people are facing, as there are literally NO other references to this that I can find. The reason why I think this is a very specific issue is that I recently got a Mate 20 X, which is essentially the same phone, and noticed that when I plug in the USB to a PC, I get a dialog pop up at the bottom of the screen asking if I want to transfer photos, files or to charge only. I NEVER saw this on the Mate 20 Pro, but that might be because I messed something up. I did do a lot of fiddling over ADB when the phone was new (mostly disabling apps) and giving permissions to apps like lightning launcher and System UI tuner and I'm wondering if this what has caused the issue.
Obviously even before I did this, I necessarily must have connected to the thing via USB, but strangely, I don't remember seeing this dialog... Having to go into developer mode to change this setting can't be how it's set up normally, as then basically no-one will be able to get connected via MTP (I suspect everyone on XDA knows about this setting, but suspect none of the average Joes even knows the option exists).
So the question is, what did we do wrong and how do we get this diaglog back because I have found that Developer mode is not accessible for other Users set up on the phone so I can't access the phone at all via USB now when the other user is using it...
I'm hoping we can work together to find out what we did wrong!
PS: I find like kaibosh99 that the USB debugging also toggles back to off. I am not rooted or bootloader unlocked
After a lot of faffing and looking into it some more, I don't get the pop-up dialog but have discovered that it is in the notification menu where it shows
USB icon . Charging via USB
Expanding that notification and tapping on it, gives the option to choose file transfer and a load of other stuff. It's a pity that a pop-up dialog doesn't open like on the Mate 20 X, you can see what I mean here

Much easier than having to go into the notification menu!

Wireless Dex

Hi guys,
I recently got my Galaxy Tab S6 LTE version in Germany and I am amazed.
I wanted to know whether someone has already looked at "force desktop mode on secondary display" and has attempted to replace the "desktop mode" with dex ...
All the best and thanks for your time,
Kevin
This is actually Android 10 feature - Android 10 Desktop mode
I know
I am wondering whether it is possible to replace the android desktop mode that is forced upon secondary displays with samsung's iteration of a desktop mode

I just tried it. Currently this option doesn't make anything when is on.
If I connect the tablet to another display just duplicate the screen. If I turn on DeX, the tablet stays in tablet mode and DeX runs on the external display.

Yeah, I've seen videos of that before
I still think you misunderstand, though I might be unclear
I do not mean starting dex.
I mean the option to FORCE desktop mode on external displays, so when I connect to a cheap chromecast-alternative from ebay (or the connect app on windows 10 for testing purposes) the internal desktop mode starts on the external device.
I wonder whether it is possible to "force dex instead of desktop mode" thus enabling me to use dex wirelessly.
I know that standard-behavior is using dex, but I need a cable with that. The force desktop mode makes the thing wireless.
SO technically it is possible to use a desktop mode (dex-like) without attaching wires.
I wonder whether it can be done in a simple way by modifying dev-settings to force dex instead of desktop mode
sorry if I am being unclear or it does not make any sense
Sure it's interesting to try but wireless displays' capability quality and latency wise are lacking. So is of dex's too.
I hear you.
I am certainly mit Up for the Task ?
If I Recall correctly, Huawei offers Wireless Desktop Mode. I hope either some clever devs or Samsung will come Up with a brilliant wireless solition...
With native Desktop Mode I guessed it being here earlier rather than later.
