Galaxy S7 Android Nougat update issues, missing click-to-call feature, other issues

As Google has began to gradually release the latest operating system upgrade, Android Oreo (#Android8) in its flagship devices, we know that you’re excited to have it in your device too. But if Android release history is our basis, most Samsung Galaxy users will most likely receive the latest update months from now. If you have a #GalaxyS7 device, it may even take up to next year to experience this new Android version.

While we’re waiting though, here are some of the operating system issues some S7 users have reported to us so far. We hope you’ll find this post helpful.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 Android Nougat update issues, SMS keeps saying failed when sending

Hello. I have a Samsung Galaxy S7 Model Number: SM-G930VL, my service provider is Straight Talk and my phone received the Android 7.0 update about a week or so ago. Since the update, I have noticed two major changes.

The first change is that home screen has shifted downward, and looks strange. I’m not sure what the point was of that change or if that was meant to be changed. Secondly, all of the messages I sent using the SMS Messaging app are said to fail even though the recipient gets my message. So my message log is filled with red letters saying “Failed” on the last thing I sent. It’s an annoying problem. I have read some threads and forums online of other Galaxy users who have experienced the same bugs after their updates. People on these threads and forums say things like factory resets don’t help. It’s quite frustrating that this is happening because my phone was functioning perfectly fine before this update. Whatever fixes it was supposed to bring, it seems only to have messed things up. Do you know what I can do? — Zoie Wiltz

Solution: Hi Zoie. First off, let’s make things clear here. Android evolves. Just like any operating system, any major upgrade brings with it both cosmetic and under-the-hood changes. And like any new thing or change in our world, not everyone likes it. If you don’t like the current look of Android 7, it’s unfortunate of you. You have 3 options: accept it, leave it, or revert to the previous Android version via flashing. The last option requires advanced Android knowledge to do so if you want to do it, you should do extra research. Flashing basically changes core system files so be very careful in doing it. One wrong step and you can potentially ruin your device for good.

Secondly, if you encounter problems after an update, the same troubleshooting and solutions apply. It doesn’t really matter much what issues you’re experiencing (unless of course it has something to do with the look). Two of the important potential solutions to your second problem includes wiping the cache partition and factory reset. We don’t know which of them will fix the problem, or if they can at all so you must do them first. If the second problem is due to inefficient or poor firmware coding, which means the carrier-provider update is inherently problematic, factory reset may not help at all. But then again, you must try them first before you’ll know. Android environment is very complicated and there are millions of possible points of failure. There’s no way we can be certain if factory reset will work.

To do either a cache partition wipe or factory reset or both, follow these steps:

  1. Turn off the phone.
  2. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Thirdly, the problem you’re having with your messaging app may only be isolated to the said app. Make sure that you wipe its cache and data first if wiping the cache partition won’t work and before doing a factory reset. Here’s how:

  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 or 7.
  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.
  5. These are all clickable items. You’ll want to click on Storage.
  6. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Problem 2: Galaxy S7 missing click-to-call after Android update

Hi. I have a Samsung S7 and can no longer tap on a phone number in a Gmail in order to call the number. In the past I could tap on a number in a Gmail email and it would give me the option either to call the number or to text the number. This function no longer exists. I have cleared and reloaded my Gmail several times and checked all relevant settings. — William

Solution: Hi William. The feature you’re missing is called Click-to-call. This feature allows an app to automatically detect a phone number and provides a working link that tells another app, such as the default Phone app, to launch to allow you to place a call or send a text. We can confirm that Click-to-Call feature is working in our own S7 when using the latest Gmail app (app version as of this writing.

Make sure that the phone number listed in the Gmail app is in a correct format for your country. The number should have the correct country code in order to work like this one:

+1 800 469 9269

Click-to-call is a default feature in most Android phones and it should be working automatically in your S7. If you have the latest Gmail app installed but click-to-call feature is still not working, consider wiping the phone via factory reset. Here’s how:

  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.

Problem 3: Galaxy S7 cannot retrieve emails from server error

I can send and receive most emails, but there are over 400 in my inbox and over 500 in trash that cannot be retrieved. It says “cannot retrieve emails from server”. It’s almost like they are stuck somewhere in my phone. I need some of those because they are certificates for discounts. Any suggestions? — Smbarc

Solution: Hi Smbarc. First of all, there are two types of protocols that a user can use when setting up an email in a device. You can either use POP or IMAP. If you used POP when setting up your email in your S7 before, the emails you downloaded must be kept locally, which means they would have already been deleted from the server. That’s because that’s how POP protocol works; messages are only kept in one device and there’s no copy in the server somewhere. IMAP, on the other hand, allows multiple devices to keep copies of the same email because the server keeps the original message. If you used IMAP in your device and your service provider supports it (most likely), you should be able to safely remove or delete your email account from your device and still access your old messages later on.

To check if you’re using IMAP, log in to the webmail version of your account in a computer and see if you can still see your old messages. For example, if you use a Gmail account, you can use your computer to log in to that email to see if Google retains your old messages. If you can, that means that you can delete the cache and data of the email app to see if that will fix the problem.

Problem 4: Galaxy S7 no option to unmount SD card

Galaxy S7 says my SD card is corrupted. I have a SanDisk SD card. I bought another SD card, same brand, thinking card may be bad. Following directions, I don’t get option to unmount. I’m afraid to go any further. What should I do? Not sure of Android version. Don’t know how to find. — Linda

Solution: Hi Linda. To unmount an SD card, here are the steps:

  1. From the Home screen, touch Apps.
  2. Touch Settings.
  3. Swipe to and touch Storage.
  4. Touch SD card.
  5. Touch UNMOUNT.

If there’s no option to unmount, that is most probably due to the fact that your phone does not detect a working SD card in the first place. If you want to remove an SD card safely, simply turn the phone off and take it out.

Unmount option is a software method of telling Android to stop accessing the SD card so you can remove it. It’s equivalent is turning off the phone so the same process can take place.

For future reference, here’s how to check your software version:

  1. Open Settings
  2. Tap About device.
  3. Tap Software info.
