The update to Android 7.0 Nougat recently arrived with plenty of new features, bug fixes, and improved battery life. It’s an exciting update but it’s far from perfect. Users should also read up on our Galaxy S7 warranty information. Especially ones facing the black screen issue or purple lines on the display.
If you’re still experiencing problems after Nougat we’re here to help. Our list covers some of the most common Galaxy S7 problems including weird battery drain, WiFi complaints, and other performance issues.
How to Fix Galaxy S7 Problems
While many Galaxy S7 and Galaxy S7 Edge owners are reporting an excellent experience, ourselves included in our Galaxy S7 Edge review, some are facing a lot of little frustrating problems. There is a big list of complaints at the Verizon forum, as well as a lot of helpful tips.
There are a lot of reports going around that users Galaxy S7 or Edge is randomly freezing, the screen may go green, white or black, and the phone makes a loud screaming type noise. If you’re one of the unlucky few with this, take it back to the store or carrier and get it replaced as soon as possible.
With that out of the way, these are the common problems you’ll want to take care of right away.
Galaxy S7 WiFi Problems
Countless reports are confirming Galaxy S7 and Galaxy S7 WiFi problems, including Gmail sync issues over WiFi. Owners have mentioned slow WiFi performance, drops, or speeds so slow they can’t even load a website or Facebook unless they turn off WiFi.
To make matters worse, a few users are claiming that if Bluetooth is on (but not connected to anything) it’s interfering with WiFi and slowing internet speeds as well.
We have good news though, Samsung and Verizon confirmed an update late last year fixed this.
That said, if you’re still experiencing Galaxy S7 WiFi problems it’s always a good idea to reset any home routers or modem. Another option is to head into settings > connections > WiFi and forget your wireless network. Then reconnect, put in the password, and connectivity should improve.
Slow Performance (Briefing)
Out of the box, the Galaxy S7 and Galaxy S7 Edge have something called “Briefing” when you swipe left on the homescreen. This is a news app that curates info from multiple news sources all to one place. However, most don’t use it but notice the lag it creates on the phone.
In fact, briefing is one of the biggest causes of slow performance, and we recommend you disable it. You can find the quick instructions below.
Long-press on a blank spot on the homescreen (which lets you change grid size, wallpaper and add widgets) and swipe over to the left which is “Briefing” and turn it off. Now, this area on the homescreen will be blank so you can add apps or widgets instead of a news app wasting space.
Galaxy S7 (S7 Edge) Bluetooth Problems
Another issue is with Bluetooth on the S7 or S7 Edge. Connection problems with car audio or stereo systems, Android Auto not connecting right, and even some 3rd party accessories.
This happens on occasion with most devices and is quickly fixed by software updates or simply repairing a Bluetooth device to your Galaxy S7. For one, unpair and repair any device trying to use Bluetooth, as that could fix it. And if any “permissions” appear during this process make sure it’s set to allow. Owners can also head into permission controls in settings and make sure they didn’t deny access to certain apps.
However, another option that typically has shown to fix Bluetooth problems is by doing a little trick. Owners can pull down the notification bar and hit the gear-shaped settings button up top. Then in settings head to Applications > Application Manager > More and find an app called Bluetooth Share as shown above. Hitting “Force Stop” or clearing the cache then turning Bluetooth off and back on again typically solves any remaining problems.
Bluetooth was a big area of concern with Android 7.0 Nougat, and other small bug fixing updates will likely arrive later this year.
Galaxy S7 App Tray
Another problem or inconvenience is how the application tray works. Apps aren’t in order, and newly installed apps get added to the back of the list, which is frustrating.
Hit the bottom right icon to open the application tray, then tap the “A-Z” button near the top, and hit save. This will now list apps alphabetically, the way it should have from the beginning, and make finding apps easier.
However, once a user installs a new app it goes to the back of the list, not in the A-Z order location. So you’ll have to hit A-Z and save once again. Frustrating, we know. Another option is to download a new “Launcher” from the Google Play Store, which often changes the look and feel of an Android device, including the application tray.
Our favorite is the Google Now Launcher which makes it similar to a stock Nexus phone made by Google. Or something like NOVA Launcher is a great choice as well. It’s customizable, and the app tray won’t act funny. Or for the latest, try the Pixel Launcher from Google’s brand new Pixel smartphone.
Galaxy S7 Camera Failure
“Warning: Camera Failed” is a notification we’re hearing a few users are having problems with at times. This could be due to a wide array of things, and we have some potential fixes.
The Dual Pixel camera takes great photos as long as the camera app isn’t throwing out this error. I’ve yet to experience it, but we’re hearing Samsung’s own “Smart Stay” feature is the cause.
Head to Settings > Display > and turn off Smart Stay, and then try the camera again. If it still doesn’t work reboot the phone, or do a hard reset by holding down power and the home button for 7 seconds. Also, try heading into settings > app manager > and force stopping the camera application as well.
Wet Speaker Galaxy S7 Problem
Samsung’s Galaxy S7 and Galaxy S7 Edge are IP68 dust and water-resistant. Not waterproof. This means it can handle 5ft or more underwater for over 30 minutes and come out working fine. This is without any flaps covering ports, or the speaker. The speaker doesn’t work right until it is completely dry.
For the most part, the phone will continue to work perfectly, but the speaker and a few other things need to actually dry out first. Samsung is using a coating on the inside, as well as surface tension where without a lot of movement the water simply won’t go in the speaker, but it can. There is a screen behind the aluminum to stop most, but not all.
Let the Galaxy S7 or S7 Edge dry out, shake it to get any water that could be in the speaker, or tap it against your hand. Once it’s dry, the speaker should sound the same mediocre quality it was before it got wet.
Disable Always-On Display
It isn’t really a problem, but some users absolutely hate the “Always-On Display” where the screen never turns off. In reality, about 90% of it is off, and Samsung’s only lighting up the pixels it needs to display the always-on information. Like the clock, date, time, battery and other things. It’s nice, but moves a lot (to prevent burn-in or ghosting) and is distracting.
Simply disable the always on display feature by heading into Settings > Display > Always On Display > and Turn it off. More details are available here.
Don’t forget to keep the Always On Display up to date. Owners can head into settings > display > always on display > and tap “About Always On Display” and then select “Update”. Recent updates introduced new features like 3rd party text support and more control over the screen.
The always on display no longer moves periodically. Instead, individual pixels move on occasion which we can’t see with our naked eye, and the AOD moves each time a user turns the screen on or off. This prevents burn in using two different methods but isn’t nearly as distracting.
Another update added sleep times where we can actually keep the Always On display enabled, but it will turn off at select times like at night, or while working. Perfect for those who like the feature but don’t want it on 24/7.
Galaxy S7 Getting Hot
These phones have amazingly beautiful displays with a powerful Quad-core processor or even an 8-core processor for models outside the United States. They can get hot while gaming, and especially while using the free Gear VR headset that many buyers received.
Also, we’re hearing a lot of complaints about it getting hot while charging. This is expected, but if you’re playing games as it recharges, things can get toasty. I use a case, so never notice this, but we can actually change settings to lower this overheating problem.
For the most part, all phones get a little warm, so this isn’t a concern. However, Galaxy S7 owners who don’t like it can head into Settings > Battery > and turn off the “Fast Cable Charging” which is Quick Charge 2.0 or Samsung Adaptive Fast Charging. This means the phone won’t charge from 0-50% in about 25-30 minutes and will take over 2 hours to recharge, but it won’t get as hot and may preserve the life of the battery.
On the flip-side, I’ve received multiple complaints from owners that are saying the Galaxy S7 isn’t charging fast. One user even said it takes twice as long to recharge as it did when he first bought it back in March. While yes some batteries will degrade over time, he actually disabled the setting mentioned above, on accident. In the battery settings menu don’t accidentally uncheck “Fast Cable Charging” or the Galaxy S7 and S7 Edge will go back to old slow charging speeds. If your phone is charging slow, check that before trying a new cable and wall adapter.
Galaxy S7 Reboot
Of course, some users may have other small problems here and there. Like screen glitches or rotation, lag, app crashes, or other minor things that can often be solved by a simple reboot. Actually, a quick reboot fixes most problems I’m asked about daily.
Owners can easily reboot the phone by long-pressing the power button, and hit “restart”. It will quickly turn off and restart back to working order.
Also, above is another method to do a hard reset. This is helpful for a frozen or unresponsive Galaxy S7, or just a simple way to hard reset the phone. Press and hold the power button and home button, together, for 7-8 seconds until the Galaxy S7 vibrates and reboots.
Galaxy S7 Factory Data Reset
Last but not least is a factory data reset. This is the last resort, as it will erase all user data, apps, messages, and content from the phone. This typically fixes any major issues, software problems and more, and reverts the phone to stock out of the box software.
This is the best route to take, and something I do after every big software update to start fresh, but it wipes out everything on the phone. Backup all data using many of the tools available, then follow the steps below to reset and start fresh. A great method is Samsung SideSwitch, or the backup solution found in settings using a Samsung account.
Start by going to Settings > Backup & reset > Factory data reset > and Reset Device. This will take a few minutes, load the Android screen and flash the stock software, then reboot to the setup screen as a new device. Restore everything, and try using the phone again. This should fix most problems.
The Galaxy S7 and S7 Edge have been available for over a year. Updates have either fixed problems, or users learned to deal with them. You shouldn’t have to though, and hopefully, our tips are helpful. Check back often for more information to fix new issues, or on software updates from Samsung. If you’re still experiencing a big problem contact Samsung for further support.
While you’re here, check out our collection of the best Galaxy S7 cases in the slideshow below.
Galaxy S7 S-View Flip Cover (Clear)
First up is a fan-favorite, being the official Samsung S-View flip case. For the S7 Samsung actually has three different S-View Flip cover cases. There's the traditional flip cover with a window like previous years, then a completely clear one, and an LED flip case. Our favorite is the clear case. This offers a full view of the entire screen, not just the small cutout like previous years.
It does everything the others do, gives quick access to information on the screen, at-a-glance information, and lets users answers calls and take pictures without opening the case. This one also has a new notification bar (while the case is closed) allowing users access to more than just missed calls or texts.
