Sharing is caring!

The Galaxy S7 may be a flagship, but it’s not perfect, despite of its advanced hardware. Many users have complained that they encountered bugs or that their devices started having a bad behavior, out of the sudden. Many teething problems have been addressed in Samsung’s first update that was released at the beginning of this month, and which solved problems related to performance, video recording, communication and battery drain, but other issues can be solved by users if they know what do to. Newbies need help and we’re here to tell them how to fix various problems.

“Warning: Camera Failed”

When you’re trying to take a photo, but the camera crashes and gives you this error, close any other application that is overheating your battery. Also, don’t let the phone in the sun, because you’ll have problems with hardware. After you’ll make sure that the phone has a normal temperature, go to Settings > Applications > Application Manager and Force Stop the Camera app, then clear data and cache. If this doesn’t work, restart your Galaxy S7.

When Your Palm Isn’t Detected

When the palm detection feature isn’t working, it doesn’t ignore accidental trackpad bumps when you’re typing and the phone keeps launching programs, you should try to hold it differently or to let it “rest” until it recovers.

When The Buttons Are Not Working

If you can’t change volume or the power button doesn’t respond, there’s a software issue and it’s fixed by hard resetting the device. So, you’ll press and hold the Power and Home buttons until the device restarts.

When The WiFi Is Not Working Correctly

Some users have complained that they encountered slow WiFi speeds, Gmail app refused to sync over WiFi, there were interferences from the Bluetooth radio and other wireless connection issues. The best thing that can be done in this situation is to turn Bluetooth off, then restart your device and re-add your favorite network. Also, you should limit your WiFi to 5GHz networks or to reboot your rooter.

Battery Is Draining Too Quickly

The Galaxy S7 has a 3000mAh battery and normally, it should provide up to 22 hours of talk time over 3G. But, if you’re using your phone for something else and the battery drains quickly, you should close some of the applications or to prevent them from downloading data in the background.
