Galaxy S7 edge can’t send emails, wifi dropping at random after installing an update

Hello and welcome to our new #GalaxyS7 and #GalaxyS7edge post. In this material, we cover three issues that not a lot of S7 users complain about, but  are still undeniably frustrating. Our suggestions can be applied to other Samsung devices as well so for those with similar circumstances but using other Galaxy models, you may get something out of this one.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

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

Problem 1: Galaxy S7 wifi dropping at random after installing an update

Since getting Nougat update on S7, I’m having big problems with wifi disconnecting randomly. Even worse, both my Samsung internet app and my Google Chrome app constantly hang on all websites visited and get a time out error. but this is ONLY when i am connected to wifi. I have to shut down all sessions of the browsers and reopen them and sometimes that fixes it. But this basically means i can no longer surf the web. The moment i turn off wifi it works fine.

Have checked other devices and they connect to the same wifi no problems so it’s definitely something with the phone since the 7.0 update. I have done what samsung suggested. All software is updated on both router and phone. I have cleared cache on phone. Didn’t fix it. I have now done a factory reset, didn’t fix it. I also have massive battery drain on the S7 since nougat update. It can drain 10 percent in 10 min now … really annoying.

Am sending it back to Samsung now for a tech to look at it, but the 7.0 upgrade killed my phone. Why samsung hasn’t released the Oreo or 7.1.1 yet i have no idea, but this means i am stuck on a phone that at home i have to leave wifi off and burn through heaps of mobile charges if i want to use the phone. — Simoncarter184022

Solution: Hi Simoncarter184022. Android problems can sometimes have unique causes depending on the device, the status of the operating system, the apps installed, the physical state of hardware, among other things. Since we have no complete history of your device, we can’t really say what’s going on right now. What you can do best is to do some basic troubleshooting to help you (hopefully) identify where the problem lies. If both these issues (wifi and battery drain) occurred after installing Android Nougat, it’s possible that there may be a coding issue behind, or you may have installed a poorly-coded/incompatible app. Below are the things that you must do.

Install Android and app updates

Sometimes, a  newly factory reset device may continue to exhibit erratic behavior because the main cause is deep inside the operating system. In cases like this, updates may be the only recourse so be sure to double check if there’s an available update for both the operating system (Android) and apps.

Restart the phone to safe mode and observe

In a lot of cases that involves connectivity and battery drain, a third party app is to blame. To see if you have the same situation, you need to observe the phone while it’s running in safe mode. When in safe mode, all third party apps and their associated services will be blocked. If your wifi connection works fine (battery drain won’t normally occur since only a few pre-installed apps will be left running), that’s a clear indicator that a bad app is behind the trouble. In order to notice the difference, you must let your phone run in safe mode for hours.

If you haven’t tried to boot your phone to safe mode before, kindly do these steps:

  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.

Observing your device in safe mode is a good follow up troubleshooting step if the problem returns after a factory reset.

Wait for feedback from Samsung

Since you’re sending the phone back to Samsung, it’s good if you can wait for the feedback that may be included during or after the check up. Otherwise, you should consider having the phone replaced to see if there’s a problem with the wifi chip.

Problem 2: Galaxy S7 edge can’t send emails

Samsung S7 edge, up-to-date software. Using the email app that came with phone. I use outlook.com, gmail.com and rogers.com. I set up accounts and they start to sync send and receive no problem for a day or so. Then I get send fails and nothing short of removing the account and adding it again seems to get it to run again for a day.  The yahoo accounts/rogers are the problem and I am wondering why if Rogers is a pop3 setup. Historically, when adding these accounts I am taken to yahoo site to enter the password during setup and when I check the setup my incoming is IMAP and my outgoing is SMTP? Is this the problem? — Tom

Solution: Hi Tom. We don’t work for Rogers and we haven’t used a Rogers email so we can’t confirm if it uses POP or IMAP. In general though, most emails are now capable of supporting both so it’s just a matter of preference for the user. All the hard lifting will be done in the background so apart from selecting the server type (POP or IMAP) and setting up, there’s nothing much that you need to do.

As regards your question about the specific server details, normally for Incoming server IMAP should be selected by default (such as imap.gmail.com). For Outgoing server, SMTP (such as smtp.gmail.com) is also the default setting so there’s really no surprise there at all. As long as your accounts are set up correctly (they must be since they worked initially), they should be good to go.

The cause of the problem might be specific to the email app you’re using so to troubleshoot it, be sure to do our suggestions below.

Force close the email app

This should be the first app-specific troubleshooting step that you should do. There may be a minor bug that has developed so refreshing the app this way should address it. To force close an app, follow these steps:

  1. Open Settings app.
  2. Tap Apps.
  3. Look for the email app in question and tap it.
  4. Tap FORCE CLOSE button.

Wipe email app cache and data

Should force closing the app won’t help, your next step is to see if there’s an app cache issue. This is done by wiping the app cache. If that will not fix the issue, you can then proceed to deleting the app data. To do both, follow these steps:

  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, look for the application and tap it.
  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 Cache and Clear Data buttons for the application. Tap Clear Cache first and observe the phone. If the problem remains, try Clear Data.

Use a different email app

Another good thing to do in this situation is to try a different email app. There are a number of good email apps in the Play Store that works similarly to the default Samsung email app. We suggest that you use those from reputable companies like Google, Microsoft, or even Yahoo. If your carrier has its own email app, try that as well.

Problem 3: Galaxy S7 edge Bluetooth stops working every two weeks

I have a the Galaxy S7 Edge (G935A), with the most updated OS I can get (Android 7.0). The bluetooth functionality just stops working about every 2 weeks. I haven’t installed any other apps, it just decides it doesn’t work any longer. I’m getting really tired of having to do a factory reset every few weeks just to get the bluetooth to turn on again. I’ve seen lots of people saying that things just don’t connect, or similar. On mine, the bluetooth just no longer turns on. I’ve tried clearing the cache, wiping the partition cache, etc. The only thing that works is doing a factory reset. It’s really a pain, to do this 2 to 3 times a month. Any other thoughts? I have even contacted Samsung support directly and they are about as helpful as you would imagine. They don’t seem to think that doing a factory reset constantly is a big deal. — Christopher Chapman

Solution: Hi Christopher. If the issue returns sometime after a factory reset, you should start focusing on a possible third party app issue. Do another round of factory reset and start uninstalling apps individually until the issue is eliminated. We know this sounds tedious (it actually is and there’s no guarantee it’ll work) but you really have no other option other than to either continue with the sporadic factory reset every other week, or phone replacement. Only you knows the app installed in the system so it’s up to you what apps to target for possible removal. There’s no clear cut solution for this since we have no way of checking the complete system log. And even if we can, knowing the exact cause can still be tricky at best.
