Problem #1: Galaxy S7 edge not receiving complete SMS delivery reports

My mobile is Samsung S7 Edge. When I am sending SMS, it is not clear that after sending SMS, I view message details; in Delivery report it says: Requested  and status shows: Sent. But it is silent and we don’t see any indication that did the receiver received. It’s not transparent whether he reads or not, and what time he read is not shown too. Also, How many times he read is not shown too.

Also, I have noticed that the search screen is on top, which should be down & special features are missing in Contacts which I need to send location to unknown # without saving. It is there but I have to select other parameters but it should be direct press on the same screen to forward the receiver.

And how to keep safe from hacking. — Joseph

Solution: Hi Joseph. In order for SMS delivery report to work, a few factors must be present. Such factors include:

  1. whether or not both carriers (yours and the recipient’s) support it,
  2. whether or not your mobile supports it
  3. Whether or not the messaging app you’re using supports it.

We are assuming that you’re using the stock messaging app so the second and third items in the list should not matter. We know that Samsung phones and their native messaging apps do support SMS delivery reports so there’s no problem in that. The main reason why you don’t seem to get the transparency you’re after has something to do with the carriers involved.

Every time you set your phone to receive delivery receipts, it sends a request to the carriers to provide you with a separate message so you’ll know the delivery status. The thing is, your request does not necessarily mean that they’re going to comply. In other words, carriers are not obligated to give you delivery reports even if you request for them. Your own carrier may comply with your request by giving you a head’s up on the delivery side but the other carrier may not comply by failing to provide a return notification to tell you whether or not the recipient received the message. This may be the reason why you’re not getting any indication if the recipient has read the message or not.

For your second question, we are not entirely sure which “search screen” you are referring to. We also don’t understand what you mean by special features in Contacts. Please contact us again and try to give more description of the features you’re missing so we can help you.

Problem #2: Newly unboxed Galaxy S7 won’t boot up normally, language set in Spanish

Out of the box my GALAXY S7 EDGE INTERNEATIONAL without warranty started in Spanish. After trying to find a way to change the language, the phone is locked in Save mode welcome screen. The root solution succeeded in a factory reinstall but it again came up on the safe mode screen with a blue line moving up and down on the screen. The two button and three button solution end up with the same safe mode screen and the blue line running up and down. The putting in and out of safe mode solution doesn’t do anything. — Dennis

Solution: Hi Dennis. If you can’t boot the phone normally, consider restarting it to recovery mode so you can do a factory reset. If this reset won’t fix the problem, you can assume that you have a bad phone. Find a way to have it replaced.

For reference, these are the steps on how to boot your S7 to recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Problem #3: Galaxy S7 edge stuck in boot loop

I bought a Samsung Galaxy S7 edge that is unlocked through Verizon from I guy I know for $100. I knew the phone was stuck in a boot loop so in my mind I thought that it was an easy fix. But the guy I bought it off of had no idea what the problem was. So I went to Sammobile and downloaded the most recent Marshmallow firmware (don’t have Nougat) and I used Odin to flash it to the device. Odin said it was successful, but then it started rebooting when it goes to optimize the apps. I tried to wipe the cache, a master reset, and I tried to use Kies, but none of those were successful.

Well I found this tool called Verizon Repair Assistant. I downloaded it and it has an option to use the Repair Assistant or the Upgrade Assistant. Well, the Upgrade Assistant doesn’t recognize my device, so I used the Repair Assistant. After it was finished with “repairing” my phone, it will now boot up to the setup wizard, but then it reboots again. I am out of options and I can’t find anything else that could fix this phone. I have tried the master reset several times since then and even used Odin again, but it won’t get past the setup wizard. I have also tried other firmwares, but Odin fails on all of them except for the Marshmallow. — Michael

Solution: Hi Michael. There’s only so much that you can do about this issue. At its worst, a boot loop problem can be also be caused by a bad hardware as well. In most cases, boot loop happens after a failed software modification. Sometimes, a corrupted bootloader can also be attributed to the problem. A user is supposed to try flashing stock firmware to fix the issue. Since you’ve already tried that, the problem must be beyond an average user’s ability to fix. That means that you may just have bought yourself a $100-brick. Like you, there’s nothing else that we can do to help in this case. We doubt Samsung can even fix it.

Problem #4: Galaxy S7 won’t charge and boots to download mode when charger is connected

Whilst playing tri peaks solitaire my phone ran out of battery. I plugged it in to charge and a blue screen came on almost instantly with factory mode at the top, product name: G930FD, current binary : Samsung official, System status : official, Reactivation lock: off Secure download : enabled KNOX WARRANTY VOID: 0 (0X0000) RP SWREV B:4 K:2 S: 2 and a big downloading icon downloading do not turn off target. When i unplug the charger, the screen goes blank and the phone won’t turn on. i plug the charger in and the same blue screen appears. I’ve tried a soft restart when plugged in and not. Only thing that happens is if charging the blue screen goes on and off . What is going on with my phone please? — Mrs Helen

Solution: Hi Mrs Helen. One of the reasons that we can think of why the phone behaves as if you’ve booted it to Odin or Download mode is a bad charging port. Sometimes, a bent pin inside the charging port can skew how a phone reacts when you connect a charger. If that’s the case, you may be able to fix the problem by checking the charging port with the help of some form of magnification so you can see what’s inside. Also, you want to make sure that there’s no foreign object inside that may be interfering with the charger when it’s plugged in. if you can see that a pin is out of place, you can either try to straighten it out yourself, or you can let a professional fix it for you. However, if everything appears to be in place, a software glitch or an unknown hardware malfunction may be behind the trouble.

Just like in other troubleshooting steps, we suggest that you try all relevant software solutions first before committing to a hardware repair, or even replacement. The first thing that you want to do here is to observe the phone in safe mode. Here’s how:

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

To see if the issue has something to do with the operating system, you can also try a master reset. Doing so will restore all software settings back to their known working state, effectively eliminating bugs and glitches. Here’s how it’s done:

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

Remember, factory reset can fix a lot of software issues but if nothing changes after you do it on your phone, that means that your S7 has a deeper hardware problem. You must consider repair or replacement if you can’t bring it back to its normal state after a master or factory reset.

Problem #5: Galaxy S7 can’t turn on Ultra Power Saving Mode | “Emergency manager service has stopped” error on Galaxy S7

Hi. When i turn on or restart my device an error says, “Emergency manager service has stopped” and a few seconds later, it says “Disabling ultra power saving mode.” This in itself is not very annoying, however, i cannot activate Ultra Power Saving mode on my device. I feel there might be a correlation between these errors and my inability to activate ultra power saving mode. Any help greatly appreciated. Regards. — Brian

Solution: Hi Brian. Emergency Manager is one of Android’s core system apps so you must treat the error just like when you do a normal one. The first thing that you want to do in this case is to wipe the cache partition. This will help ensure that Android is using an updated system cache. Sometimes, updates and installations can corrupt the system cache, resulting to problems such as causing apps to work erratically. Wiping the cache partition will force the phone to build a new system cache. Here’s how it’s done:

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

Should the phone continues to exhibit the same errors or problems, you can also try to wipe the Emergency Manager Service’s data. Unlike normal apps, this one can’t be uninstalled so you are limited to performing a virtual reinstall by wiping its data. Here’s how it’s done:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. 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.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

We think that the main issue of you not being able to turn on Ultra Power Saving Mode is tied to the “Emergency manager service has stopped” error. If the problem continues after you wipe the app data, your next move would be to wipe the phone with factory reset. This issue is most likely a software problem so we believe a factory reset will fix the issue for good.

Problem #6: Galaxy S7 “Unfortunately the process com.android.systemui has stopped” error when pressing Home button

This is for my Samsung Galaxy S7! Every time I hold my home button my phone comes up with the error “Unfortunately the process com.android.systemui has stopped” (I attached a photo of it). After I hit “ok” my phone kind of freezes, my wallpaper turns black for a second, and it goes right back to my lock screen. I am unsure how to fix the problem and the last thing I did differently was try to download a wallpaper for my phone off of some website on google. I also did that 2 days ago, but when I downloaded it I could not find the download in any of my “downloads” or pictures. I haven’t downloaded any new apps for at least 2 weeks either. I would appreciate any of your help to fix my phone, and I am sorry if this is slightly confusing. — Meghan

Solution: Hi Meghan. We haven’t encountered this problem before so it’s either a rare issue with Samsung devices, or an isolated case due to something unique to your phone. We hope that the problem is not due to hardware malfunction. To verify this, kindly do the following:

  1. Open the Phone app.
  2. Dial “*#0*#” (without the quotes).
  3. Select the Sub key box.
  4. Press the Home button. If the screen turns blue after you pressing the button, that’s an indication that it’s ok.

The next thing that you want to do then is to check whether or not the problem is being caused by a third party app. You can do that by restarting the device in safe mode. If the error won’t show while safe mode is on, that’s a confirmation that one of your apps is to blame. Here’s how to do it:

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

Should the issue remains even when you restart the device to safe mode, the cause may be found on the operating system level. In this case, you want to factory reset the device. Doing so will force the phone to return all software settings back to default. If you haven’t tried a factory reset before, doing it now may be the only to resolve the issue. We are assuming of course that you did not root your phone or modified the official Samsung software. If you did any of these things, you can also look at the possibility that a custom software may be to blame. In this case, you must reach out to the developer or the community that creates or uses the said software for answers.
