I would like to enable Do Not Disturb on a phone via ADB. I have located the settings namespace and key which controls Do Not Disturb: adb shell settings put global zen_mode 2 But when I run this command and then get the key its value remains set to "0". If I enable Do Not Disturb manually on the phone, then look at the key, it shows "2" as I expect. I am using stock Samsung S7/S7 Edge phones, with Android 7.0, not rooted. Is there a step missing in order to toggle this particular setting via ADB? Thus far I haven't had issues changing any other settings in this way, so it's confusing why this does not work.

I'm trying to have my Samsung Galaxy S7 phone start up into normal operation when USB power comes on. I have tested all the suggestions in [this post](https://stackoverflow.com/questions/4169387/how-to-make-android-device-boot-when-power-is-plugged-in) and several others, but whatever I do the phone will not reboot into normal operation. My result is no reboot or reboot into Recovery mode. I have also tested several ROMs with same result. There seems to be a problem when the \system\bin\reboot is called in LPM (Low Power Mode) mode. Script: #!/system/bin/sh /system/bin/lpm_orig & while [ true ]; do sleep 1 ps | grep lpm_orig && sleep 3 && /system/bin/reboot done (The "lpm_orig" is the original lpm file). Linux owner and execution rights have been checked. Does anyone have an idea what to try next?

After I recently updated my phone about a day ago, this strange sign that looks like a 3/4 circle with a plus inside it showed up on the top left that I have never seen before. Does anyone know what it means? Or how to get rid of it?

I am using a Samsung Galaxy S7 Edge on Android 8.0. I want to remove app suggestions on the search bar. I already checked for some solutions on YouTube. Everyone tells me to go to Home Screen settings and then go to suggestions, but there are no options named suggestions.

I'm having trouble with my new branded Vodafone Samsung Galaxy S7 Edge.  How can I get a copy to the full logs (and other files), without rooting, for places I do not have the required access? I can read the logs in recovery booting, but how can I transfer digital copies of these logs as text to for example my email?

I have a manufacturer-unlocked Samsung Galaxy S7 Edge (purchased directly from samsung.com), which came with Marshmallow but has been updated OTA to 7.0 Nougat, and is not rooted. One new feature Marshmallow brings is the Blue Light Filter, which has options for automatically turning on and off, either according to a schedule you specify, or at night based on your local sunset and sunrise. I'm using the latter option, and while I've found the filter to reliably turn on every day at sunset, I frequently have to manually turn it off the next day. It's not 100% of the time though, and in fact, on rare occasions, I have woken up before sunrise and been *using* my phone when the filter suddenly turned off, so I know it is at least *capable* of working properly. (Note that it has never, to my knowledge, failed to turn *on* at sunset, regardless of whether I'm using it at *that* time or not.) I'm speculating that maybe it's failing to turn off if the phone is in deep sleep mode at sunrise. The times of sunset and sunrise are determined based on your location, so an as-yet-unnoticed issue with Location Services could theoretically be a factor as well. I did a Google search and was able to find informational articles about the feature in general, as well as multiple forum posts from users experiencing problems getting the feature to turn *on* or work *at all,* but found no reports of it otherwise working properly, but not automatically turning *off.* Am I the only one experiencing this issue? Is it something specific to the S7 Edge, or to Samsung builds in general, or is the same problem known to occur on other devices? And of course, most importantly: **How can I get the Blue Light Filter to *reliably* turn off at sunrise?**

I have a Galaxy S7 and it is locked so I can't add new languages. Can someone tell me if this is possible without root?

I have Samsung Galaxy S7 Edge on Android 8.0 Oreo (). Until yesterday, application notifications were flashing on the LED indicator, but from yesterday to today it stopped happening, even though nothing updated on the device. It warns that it is charging with the red LED, and it warns when it has finished charging with the blue LED, but it does not flash to notify that there are new notifications as it used to do. I checked if LED it's enabled, and yes it is. I already checked if the applications are activated, yes they are. I checked if it's in DO NOT DISTURB mode, and it's not. I haven't changed any settings from yesterday to today, however, this is happening. What can I check to try to find the problem?

I have an app that performs automatic actions, but for that it needs to unlock my screen. It doesn't have the Swipe + Pin option. Pin only. In version 8.0 of Android (latest for Galaxy S7 Edge) is there a way to make the screen turn on already on the screen where you type the Pin instead of having to do a swipe before it appears? It is currently swipe then pin, see:

I have a S7 Edge Phone (G935FD) Single SIM, after googling the only CF Auto Root file was here CF AUTO ROOT LINK Which shows for G935F however some said it works for FD as well. While rooting via ODIN I got the message that says "Recovery Is Not Seandroid Enforcing" and then it rebooted and stuck on the Samsung Boot Logo after the S7 Edge logo. Tried all known possible ways yet not booting any advises please?

My phone is not allowing me to download the VR app for my Samsung Gear... The download button is not coming up for me to tap.I tried restarting my phone several times.

I want to remove old saved networks that are no longer in range. I can forget visible networks, but out-of-range networks are not visible anywhere so I can't do the standard long-tap => "Forget Network" action. There is no option for "Saved Networks" or "Manage Networks" under the built-in Wi-Fi app's "More" menu. I have tried a third-party app, [WiFi Manager](https://play.google.com/store/apps/details?id=org.kman.WifiManager&hl=en) , where the networks are visible but reported an error on forget: > Android 6 allows apps to change (edit password, forget) only those networks that were originally "created" in same app. I quite distinctly remember being able to view saved networks on previous Android phones... --- My phone *is* rooted, so methods requiring root are acceptable, but it's better if that's not necessary. --- I have an Australian (CSC XSA) Galaxy S7 Edge (SM-G935F). --- Apparently this was a problem with the S6, where the 'solution' was to use third-party Wi-Fi management apps that no longer work in Marshmallow. * http://forum.xda-developers.com/galaxy-s6-edge/help/how-forget-range-wi-fi-networks-t3137257 * http://forums.androidcentral.com/samsung-galaxy-s6/596840-how-do-i-forget-saved-wifi-networks-when-they-out-range-samsung-devices.html * http://forums.androidcentral.com/samsung-galaxy-s6/567924-how-do-i-remove-saved-wifi-other-locations-my-samsung-galaxy-s6.html * http://ericscorner.blogspot.com.au/2016/02/how-to-remove-out-of-range-wifi.html But that no longer works, as per the error message above...

Since last week I upgraded my Samsung Galaxy S7 Edge from Samsung's stock firmware to LineageOS 18.1 by using this message of the XDA forum and installed the "full" edition of NicGApps. Since yesterday the camera does not always work, which is a behavior I never experienced on the stock Samsung firmware at all. When I open the camera app the screen is black. Also, when I change to the front facing camera. The only **temporary solution** is to reboot my device and everything works again. During these two days, I rebooted my device three times, and that cannot be the intention. I tried this with several apps: OpenCamera, Footej Camera, the QR Code scanner of my banking app, all the same and as I wrote, after a reboot everything runs normal again. Does someone know a permanent solution?

My Samsung S7 Edge (Android 7.0) has lately developed the following problem: every once in a while, at seemingly random times, the internet stops working - in any app, and both on WiFi and on mobile. Connectivity is only back to normal when I restart the phone. This occurs maybe once every 2 days or so, and is as you can imagine very disruptive. I've let it update the OS but even the most recent update did not fix (it may not even acknowledge) this bug. Any ideas?

I rebooted my Samsung Galaxy S7 Edge this morning, however, upon restart any applications that are on the SD card and in a folder get the message "App Not Found" when trying to launch. These apps also have the grey SD card icon. Moving the app out into the root tray allows the application to launch. However, moving the app to internal storage doesn't. Uninstalling and reinstalling an app doesn't help. Neither does clearing system cache. Is there a fix for this? The workaround is to move all apps out of folders, but this means I can't organise them as well.

Recently my S7 edge got blank screen and last thing I saw was samsung logo then it turned off and I don't see anything else only black screen. I tried using that vol up/down power/home force restart but device didn't respond it's fully charged and when I charge the phone fnothing shows up. I don't know if this is correct community for troubleshooting this kind of problem but I need help.

I have a somewhat old Samsung S7 Edge phone which (strangely enough) has only the lower half of the screen not working. This is, the whole screen lights up and displays everything, but ONLY the lower half is unresponsive to touching. As such, I cannot unlock it and turn usb debugging on. It is not rooted nor do I know how to do it; I don't really know a thing about coding. I have seen many previous threads and web pages about this, but at most I am very confused and don't want to brick it. It doesn't have any really important files, but very old GBA roms I would really like to keep, as well as some photos and pictures I may have. Any help appreciated!

I never wrote my password down for my old S7 Edge and managed to forget it. Overthinking the security and privacy, I also never signed up for Samsung's service and Google's Find My Phone only recognizes my current phone -- so I can't use those online services to reset the password. I'm wondering if there's a super-user method to get into the phone (or extract data) ***without wiping the data with a hard-reset***. In the Android Recovery screen (volume-down, home, and power buttons held simultaneously), I have the "Apply update from ADB" option but sideload seems to be the only functionality and the handshaking seems wrong. The resulting messages on the Android are:

Finding update package...
    Opening update package...
    E:footer is wrong
    [...]
    E:signature verification failed

I found online somewhere that the password file for the phone model is in

/data/system/gesture.key

and

/data/system/gesture.key

would be *ideally* what I'd like to bring about. However, I can't use a command such as

shell

on it without the password. I also haven't figured out a way to inject and run a script (particularly with the handshaking and with adequate privileges for the phone) with that

command using

sideload

. More details or seeming dead-ends: - The phone was not rooted. - I'm *fairly* certain I enabled USB debugging. - It's a SM-G935W8 (Canadian) model with hero21tebmc (firmware?). - Samsung's Smart Switch software is also not an option to transfer data (w/o knowing my old password). - The third-party software I've seen and tried on a friend's Winwoes laptop doesn't have the password-reset capability on the S7 Edge... it would work if it was an S6 or older unfortunately. - the Android Recovery screen has other options including: "Apply update from SD card", "Mount /system", "Wipe cache partition", and the dreaded "Wipe data/factory reset". - I'm using a Linux distribution (Ubuntu 18.04) and would use heimdall on the command line (instead of the Odin software). These links, [Official TWRP for Galaxy S7 edge (hero2lte)](https://forum.xda-developers.com/s7-edge/development/recovery-official-twrp-hero2lte-3-0-0-0-t3334084) or [Flashing Firmware on Linux/Ubuntu using Heimdall](https://forum.xda-developers.com/s7-edge/how-to/guide-flashing-firmware-linux-ubuntu-t3486298) , are likely to be the instructions I'd follow with due care. If I persist and try to use [TWRP](https://twrp.me/about/) or some sort of program to "recover" my data it seems highly likely to wipe it (even if I don't proceed to root it). Along the same line, I suspect installing [LineageOS](https://www.lineageos.org/) would wipe the data in the process and there's probably no way to sift through the wreckage of the data (which is probably without pointers/inodes but presumably not outright erased) in some kind of brute-computational-force way either. Is there any way to get at the data (instead of waiting every hour to try to re-discover a strong and essentially gibberish password)?

One of my phones is a Samsung Galaxy Edge S7. One of the apps, Samsung Pay, is uninstallable bloatware. The problem is that when Samsung Pay is running it takes up the bottom edge of the home screen such that it interferes with the upward swipe operation when opening the home screen after the screen is locked. I discovered that I can get rid of that problem temporarily by force stopping Samsung Pay. However, at some point in time either via a reboot or a system update or something else, the Samsung Pay app gets restarted. Then, I have to hunt through the menus every time and force stop Samsung Pay again, manually, which is a hassle. So, how do I arrange it so that Samsung Pay is forced stopped at some point after each reboot, or better yet, every time that Samsung Pay is running? I searched the Google Play Store for app killers, and none of the ones I examined explicitly state that they provide a way to kill a user-specified application after each reboot. Or, if there is such an app, it would force me to try hundreds of ad-infested apps before I found the right one, which is also a even more annoying hassle. I would be happy if I could install an app on the home screen that, when clicked upon, would force-stop only the Samsung Pay app. That would not be fully automatic, but it would suffice. Buying a new phone is not an option. Rooting the phone is not an option. Any method that requires signing into Samsung Pay which requires creating an account which is tied to the phone is not an option. For example: https://www.androidcentral.com/how-disable-samsung-pay probably would disable it, but my experimentation shows that it is requiring an account just to get to the screen that allows you to disable it: thus is a email harvesting scam.

I have been searching a lot, and, I am unable to identify this app on the notification bar as showed in the image. The icon with a blue circle and a rabbit on it. If anyone can recognize it, that will be very helpful.
