Prior to the recent update (Nougat, I believe) my phone worked fine, sent and received pics/texts, and didn’t get hot. After the recent update, my Galaxy S7 Edge could receive but not send/text pictures. It could send and receive texts. It also got extremely hot when running and ran slower. The battery ran out faster and took longer to recharge. The error given when sending the pictures failed “message not sent invalid destination address.” I took it to the Verizon Store, they forced me to use their Messages+ “because that’s what works,” yet it didn’t. Then they ordered a warranty replacement. The replacement still is on the pre-update OS, which I like better, but it still won’t text pics- gives the same error. Other apps seem to work fine. Any recommendations? — Koidream
Solution: Hi Koidream. If everything was working fine prior to the update, the phone’s APN settings must have been changed for some reason. Installing a system update requires changing core files so a bug may have changed the network settings by mistake. Like in all update-related problems, you want to do the basic software troubleshooting first.
Wipe the cache partition
The first troubleshooting step that you want to do is to clear the cache partition to ensure that the phone’s system cache is fresh. Installation of app and system updates can sometimes corrupt the system cache so you want to ensure that this is not the cause by wiping the cache partition. Here’s how to do it:
- 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.
Make sure that all apps are updated or compatible
This troubleshooting is part of the general update-related troubleshooting so even if the rest of your apps are working, we still want you to double check all your apps to make sure that they are compatible with the new Android version.
Boot to safe mode
Booting to safe mode is not a solution in itself but a way to determine whether or not a third party app is causing the trouble. Safe mode blocks third party apps and services so if you enable it, only pre-installed apps will work. If you’ll be able to send MMS in this mode, that’s an indication that one of the apps is problematic. To boot your S7 to safe mode, follow these steps:
- 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.
Ensure that MMS settings are correct
Before you do this step, make sure that you contact Verizon for the correct APN settings that should be in your phone.
- Open Settings app.
- Tap Mobile networks.
- Tap Access Point Names.
- Tap Add.
- Edit the phone’s APN settings and ensure that you enter all correct values in applicable fields.
Turn on mobile data
A lot of users often forget this common sense step in troubleshooting MMS problems. Be sure that you have a good working mobile data subscription before sending an MMS.
Do a factory reset
This is an optional troubleshooting step, especially that the issue happens on the second phone as well. If you haven’t done it before, consider performing it only immediately before calling your carrier again for more support.
- Create a backup of your important files.
- From the Home screen, tap the Apps icon.
- Find and tap Settings and then touch Backup and reset.
- Tap Factory data reset and touch Reset device.
- If you have screen lock feature turned on, enter your password or PIN.
- Touch Continue.
- Tap Delete all to confirm your action.
Contact your carrier
If all the steps above won’t work, your carrier should help fix it themselves. There may be account-related changes that causes the problem.
Hello Samsung. I bought a Galaxy S7 Edge when I was on vacation in Vietnam, and it has worked well for the past 2 months. I recently selected a factory restart, and this has created a problem as the phone will not connect during the “system setup.” Basically it will say “Checking connection… This can take a while.” I have tried to complete this procedure several times and have waited for several hours. I believe that the problem may be due to the fact that I live in Mainland China, and their Firewall may be stopping my phone from connecting to any Google related services. Would you be able to help me find a way to somehow use my phone? I would like to thank you in advanced for any help that you may be able to provide. Sincerely. — Brad
Solution: Hi Brad. Samsung devices running Android Lollipop and above are protected by FRP or Factory Reset Protection which is basically just another security layer that will verify the registered Google account. FRP works by asking a user to enter the correct Google account credentials during a factory reset so you may be right in the fact that your device is trying to contact Google servers during this time. There’s no way to skip this Google account authentication so you must do it if you want to continue using the phone. To fix the issue, you must connect the device to a wifi network that’s not affected by China’s firewall restriction. We don’t know if you can do that but it’s the only way to connect to Google servers.
Hello I have a Galaxy S7 and since the update to Android Nougat 7.0, my phone restarts randomly, it can stay an entire week without restart and it can also restart 2 days in a row. It’s totally random. I have reset to the factory settings and I have reinstalled only the most important applications (Facebook messenger, Viber, Yahoo mail) but unfortunately about ten days after reset, the problem has reappeared. What could be the cause of this problem? For info, the firmware version installed on my phone is: G930FXXU1DQBO.
Also, I saw on SamMobile that the countries that received the update later, had a new version. Could the problem come from that? Is this a bug in the firmware installed on my Galaxy S7. Thank you in advance for your help. — Aminejaoua91
Solution: Hi Aminejaoua91. There’s no direct way to check if this is a bug in the new firmware running in your phone. The best that you can do is to observe the phone while it’s on safe mode to see if the problem is being caused by third party app. Due to the random nature of the problem, you will have to boot the phone in safe mode as long as possible to see the result. Kindly refer to the steps above on how to boot your S7 to this mode.
If the problem will happen even when the phone is in safe mode, it’s either due to a firmware issue or a hardware error. Either way, make sure to let your carrier know so they can replace the phone.
When I receive long texts, approximate >300 characters, the entire message doesn’t come through. At the bottom, it has the message icon, says ‘View all’ and there’s a > arrow. Clicking the view all gives me a blank screen with a subject. Holding and clicking the view all gives me message options, but nothing to display the entire message. I see delete, forward, share, lock, save attachment, view slideshow. I went to the settings, apps and couldn’t find an option to fix this. Somehow it seems I should be able to download or view the entire message, but I can’t figure it out. Thanks in advance for your help. — Johnd.shannon
Solution: Hi Johnd.shannon. We’ve already received a number of similar reports from some of our readers so we think that this is a firmware bug. Unfortunately, this means that you will have to report the issue to your carrier if the usual dose of software troubleshooting like wiping the cache partition and factory reset won’t resolve the problem.
As a remedy, try to use another messaging app for now and see if that will work. You can check out the many free messaging apps in the Play Store for that.
Hi Thedroidguy. I have an issue with my Samsung S7 mobile phone. Whatever i am doing like texting/SMS, surfing and gaming, the touch screen just suddenly become unresponsive for hours. The phone itself i believe is working fine since i can see messages popping up in my screen, however, the touch screen is the problem. The buttons outside the screen like home and back are working. I tried using all the troubleshooting tips, like rebooting, resetting factory setting, wipe cache partition, but to no avail. I remember this is working fine in Android 6.2 but now since the update of Android 7.0, this issue keeps on happening. Should I downgrade it to Android 6.2? Please help. Thank you very much. Best Regards. — Edwin
Solution: Hi Edwin. We have not received identical or similar reports from other readers so this is most probably an isolated case. If you’ve already tried all software troubleshooting and nothing helped, we suggest that you contact Samsung or any relevant party (like your carrier or retailer) so the phone can be checked and/or replaced.
We don’t recommend that you downgrade the firmware to the previous version due to security reasons but if you want to do it anyway, do it at your own risk.
