Samsung Galaxy S7 problems: first things first

Many of the problems we’ve seen reported are teething problems, and many such problems have been addressed in Samsung’s first software update for the Galaxy S7 and S7 Edge. That hit T-Mobile on April 4 and is rolling out to other carriers as we speak; it solves a whole range of niggles including performance problems, video recording issues, battery drain and communications bugs.

Samsung Galaxy S7 problem: “Warning: Camera Failed”

Is there anything more annoying than going to take a photo and your camera crashing? Luckily this one’s pretty rare, but some users are reporting that the “Warning: Camera Failed” error is preventing them from taking pictures.

First of all, make sure your phone isn’t overly hot - letting phones sit in the sun, for example, can cause all kinds of issues with hardware - and then do a hard reset by pressing the Home and Power buttons until your S7 restarts. If that doesn’t work, go into Settings > Applications > Application Manager, find the Camera app, Force Stop it and clear its data and cache.

Samsung Galaxy S7 problem: palm detection isn’t working

Your S7 or S7 Edge both have a palm detection feature, and its job is to ignore accidental bumps when you’re holding your phone or tapping on its screen. You’ll find something similar in laptops to ignore accidental trackpad bumps when you’re typing.

In some cases the detection doesn’t appear to be working in the Galaxy S7, with accidental bumps or certain ways of holding the device triggering the display. Unfortunately there doesn’t appear to be a software fix for this one just yet; if your phone keeps launching things when you grip it, try holding it differently or putting it in a case. Not the most stellar advice we know, but it does work.

Samsung Galaxy S7 problem: the buttons aren’t working

One minute everything’s going just fine, the next your volume controls aren’t changing the volume and the power button doesn’t do anything. It appears to be a software issue rather than a hardware one, because you can usually fix it by pressing one of the buttons that doesn’t appear to be working. Press and hold Power and Home to perform a hard reset and you should find that your buttons are back in business.

Samsung Galaxy S7 problem: the Wi-Fi isn’t working properly

This is one of the big problems supposedly fixed by the software update: many owners reported painfully slow Wi-Fi speeds, interference from the Bluetooth radio, Gmail refusing to sync over Wi-Fi and various other wireless connection and performance issues.

If the software update isn’t available for your device try turning Bluetooth off altogether, hard resetting your phone and removing then re-adding your favorite networks. You could also try limiting your Wi-Fi to 5GHz networks, as that frequency band is unaffected by Bluetooth signals. And it’s always worth rebooting your router if you’re at home, as routers can - and in our experience do, far too often - stop working properly for no good reason.

Samsung Galaxy S7 problem: Briefing is killing performance

Here’s an issue that can affect Samsungs of all kinds: the Briefing app, which is designed to bring various news sources together into a kind of 'Daily Me' news round-up, has roughly the same effect on performance as getting a sprinter to run with a 300-pound man strapped to his back while wearing waders. If you long-press on a blank bit of the home screen you can then swipe to Briefing, turn it off and feel your S7 breathe a big silicon sigh of relief.

Samsung Galaxy S7 problem: Bluetooth is borked

This is a common problem in new devices, especially ones rocking brand new system software. If your Bluetooth isn’t behaving it’s worth removing your list of paired devices and re-pairing them again.

Samsung Galaxy S7 problem: battery’s draining far too quickly

This is usually an app problem. Turn off anything you don’t need in the Notifications shade, and go into Settings > Data Usage > Background Data to prevent apps from downloading data in the background when you don’t want them to. Turning the screen down always helps, but don’t worry about turning off the Always On display: Samsung promises that its effect on battery life is negligible.

    Since the update to 7.0 on my galaxy s6 edge I can't access my private mode. It comes up with the message "failed to enable please try again" I've seen online other's referencing changing something in developer options but it's not there. Please can someone help me access private mode. I've things in there I don't want to lose.

    Hi I have encountered a peculiar problem barely a month into the ownership of the s7 edge. The always on display and the night clock are showing weird background colours.. just started yesterday night.. wish this is a minor issue. Doesn't look good though

    My new S7 is Fabulous, whoop whoop. I used to think my S5 was the best device, but my S7 rocks.

    1 little issue though.... Why do I have to turn of apps that appear on top (screen overly) when accepting app permissions?

    Peace 🖖

    I've searched all over, but haven''t come across someone with the same issue that my S7 Edge has. I randomly (sometimes even when the phone isn't plugged into anything) receive a pop-up message stating:

    "Check port

    Moisture has been detected. To charge your device, make sure your charger/USB port is dry."

    It's a great feature; however, I've never gotten my phone wet. This all started about a month ago, when I plugged my phone in via my car charger. I have a wireless at home, so I wasn't too concerned. I just figured there must have been some moisture that got in there, that I hadn't noticed. This issue hasn't gone away since.

    Occasionally, I am able to plug in the phone and not receive the pop-up; however, in the last week or two, the error message will just pop-up randomly, even when I am not or haven't even tried to plug anything in. This phone was pre-ordered, and I received it on March 8th, 2016. (Three days before the March 11th launch.) I don't know if there was an issue with that first batch or if I've just got a bunk phone, but this is very annoying.

    Warning Camera Failed - An interim fix:

    The culprit is Smart stay: Go to Apps -> Settings -> Display and turn Smart stay off. Restart the S7/S7 Edge and your camera will be back working again. Smart stay uses the Front camera to realize when you are looking at the screen and there appears to be a conflict when you try to start up the Rear camera. I understand that Samsung are aware of the issue.
    Hope this helps.

    As well, in the update from APB7 to APD3 and the subsequent "Always On Display" update, the clock no longer moves on the screen.

    Great phone and all. But you can't watch anything on VR gear bc the phone over heats and crashes..

  • Bonny Rupert Apr 25, 2016 Link to comment

    Phone stays on but screen is black. You can't answer it when it rings and your notifications still work. I learned that a soft reboot is what's needed to get your screen back. What needs to be done to prevent this from happening?
