Problem #1: Galaxy S7 Active does not receive notifications | Galaxy S7 Active can’t set vibration notification for SMS

I have been having issues with my new S7 Active from the start of receiving my phone on 12/21/16. The first issue is that even when my settings notification is turned on, I still do not receive a notification. It does vibrate, however I don’t hear a notification even though I’ve tried everything from your suggestions. It cannot be an app, because this is a new phone and this has been happening since I activated the phone.

The second issue is that I can not turn my text notifications all the way off, like I could with the S6. I can turn the ringtone all the way down to vibrate. With my S6, if I held the volume down button longer, it would go to off instead of vibrate. The only way for me to stop the vibration all the way is to turn off notifications all together through settings, but I don’t want my notifications off, just no sound. Again, this occurred from the start of activating my phone so I do not believe it can be a third party app causing the issue. Please advise! I work in a school, so must have it on silent and not vibrate however I do still need my notifications to come through silently so don’t want to turn all the way off. Thank you in advance. — Toni

Solution: Hi Toni. Just as there’s an app for almost everything, an app can also cause all sorts of trouble. Just to be on the safe side, we want you to observe the phone how notification works when you boot the phone to safe mode. As you probably have known already, safe mode blocks third party apps and services from running so it’s a good way to test our hunch. Restart the phone to safe mode and observe it for 24 hours. This will give you long enough time to see the difference. If you haven’t tried doing this before, here’s how it’s done:

  • Turn your Galaxy S7 off.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

If what you claim is true, that it’s not a third party app issue, the next logical troubleshooting steps should be recheck your phone’s settings. The first one involves going under Settings>Notifications and making sure that all the apps you’re expecting to give notifications have notifications enabled for them.

The other setting you want to check is the “Do not disturb” option under Settings>Do not disturb. If you enabled Do not disturb, your phone won’t receive any alerts so make sure that it is disabled.

For the second issue, you must change the settings under Settings>Sound and vibration>Vibration intensity>Notifications. If that won’t work, we don’t know what will.

Problem #2: Galaxy S7 Recent apps button not working

Hi. I am having issues with my Samsung Galaxy S7.

1.) Message Notifications and other notifications all disappeared — I can’t see the messages if i will not open the app

2.) Blue LED light — it keeps on blinking but there’s no notification seen at all

  1. The left button for the shortcut of all the apps and all the stuff opened is not functioning. I can’t see the open apps and etc through that button now
  2. The double click launch for camera is not working as well even in the setting, it is ON.
  3. On top of the screen – where you can just slide down to see the settings and all ( wifi,location, sound, auto rotate, … its not showing me all other settings, and even the shortcut for the setting key is not working at all. (it’s like the sensor is not working- but it is working with other buttons. — Celeste

Solution: Hi Celeste. To fix all these issues at once, we suggest that you try wiping the cache partition first. Sometimes, updates and app installations can corrupt the system cache, resulting to some apps behaving erratically. This can be easily be fixed by wiping the cache partition though. Here’s how it’s done:

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.
  • Observe the phone for a few hours.

Should the issue remain after wiping the cache partition, don’t hesitate to do a factory reset. Here’s how:

  • Create a back up of your important files.
  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

For the third issue, there’s a chance that the Recent apps button may not be working due to physical damage. To check if that’s the case, try checking it under your phone’s service menu. Just follow these steps:

  • Open the Phone app.
  • Dial “*#0*#” (without the quotation marks).
  • Tap Sub key box.
  • Tap the Recent Apps button. If the screen turns to orange, that means that the button is detecting your touch and should work. If the screen turns black or doesn’t respond, that’s means that the button is dead. In this case, you must send the phone to Samsung so the defective hardware can be replaced.

Problem #3: Galaxy S7 S Planner does not have option to add tasks

I previously owned a Galaxy Note 3 model SM-9005 and backed up my data via Smart Switch version 4.1.16121_3 prior to trading in the phone for a new Galaxy S7. After restoring the data to the new phone, I noticed that I do not have the option to add tasks to the S Planner in the S7. I see a green bar at the bottom of the app saying “+ Create events.” This option gives me the ability to create events but not tasks. Additionally I can only view the S Planner in the “Month view,“ there are no other options. A Samsung rep has looked at the device and suggested that I try syncing Google calendar entries with S-Planner. I even set a dummy event and task in Google Calendar and synced it to the S-planner. I noted that the event synced OK but there is no visibility of the dummy task. I do not need to see past tasks, I just want to be able to add tasks to my new S-Planner in the S7. Please help. — No Task Guy

Solution: Hi No Task Guy. The ability to add task in S Planner should be part of the drop down menu, where you can change the S Planner view. If you can’t find it there, that means that the app may need to be updated, or it may be corrupted. To fix it, simply wipe the app’s data. Here’s how:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, click on an application.
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

Problem #4: Galaxy S7 freezes when not being used

Hi. Please help. Just bought a second hand S7 edge last Dec 26, 2017. It was working ok but somehow it is keeps freezing and it mostly happen when the phone is not in use. Before it hung like after 3 or 4 days but this week i have encountered it daily for 3 days already. it freezes same only when not in use. What I’m doing is I’m restarting it. It usually work and goes back to normal but i hope this will be fixed in some point. I did already hard reset and factory reset its all the same thanks for the answer. — Angel

Solution: Hi Angel. If the cause of this issue is a software glitch, factory reset should have fixed it already. It’s either a bad third party app or some unknown hardware malfunction. Try to boot the phone to safe mode for at least 24 hours and observe it. If the freezing issue won’t show during this time, you may be lucky as the most probable cause can only be an app. To identify the problematic app, uninstall third party apps individually and observe the phone after every uninstall. If the problem remains even when safe mode is enabled though, the problem should be hardware in nature. This means that you will be unable to fix the issue on your level. Consider getting a replacement if the issue persists.

Problem #5: Galaxy S7 edge keeps freezing on Always on Display screen

Hi guys. My S7 edge crashes 1 time per every 4-5 days. The screen just freezes at “always on display” when I don’t use the phone. Sometimes at night sometimes at day time. Home button and Power on button become unresponsive. Only thing it helps is to restart the phone. I made HARD RESET on the phone but the problem is still here. I read somewhere that maybe the glass protector makes the phone to crash but i don’t believe it. Any suggestions ? — Alexandar

Solution: Hi Alexandar. Your issue appears similar to Angel above. Please refer to our suggestion for her.

Problem #6: Galaxy S7 has poor signal reception

Hello! I have a phone that has extremely poor reception. No amount of restarts or hard restarts has fixed the issue. The poor reception affects all bands: 4G, 3G (3.5G and 3.75G included), and 2G (incl. 2.5G). Someone else in the same network can have full or near full reception and I have absolutely zero connectivity. Judging by distances to link stations it seems to me that the phone must be no further than 1-2km away from a link station in order to have reception. Even at the root of a link station I do not have full reception, ever.

I haven’t tried factory resetting the phone but during the low reception period I have updated the phone twice, one of them being a major update. As far as I can tell the phone performs a factory reset during this process.

On your forums I found issues related to losing data only or losing all network connectivity which isn’t the case with my phone. There was one response that vaguely referenced antenna problems and having to check with an engineer. I’m fairly savvy with screwdrivers and hardware so to your knowledge of similar problems will an antenna replacement fix the issue or is it software related? The original frame seals are still intact (and somewhat tedious to replace) so I don’t want to open up the phone unless it is necessary.

Thanks in advance! — Elias

Solution: Hi Elias. An issue like this can be caused by a bad baseband or a malfunctioning antenna. Baseband refers to the firmware used by the phone’s modem. Baseband updates are usually included in most major Android updates so if you have a pending system update, make sure to install them. If there’s no update available at this time, consider doing a factory reset so the phone is forced to receive an update afterwards. If nothing will improve after a factory reset, then you can assume that hardware may be to blame. It can be an antenna issue or something else on the motherboard. Our blog does not provide hardware troubleshooting and solutions though so try looking for guides somewhere.
