Android Safe Mode
ANDROID SAFE MODE
Allows you to boot up your device with only the core preloaded applications running, meaning any apps you’ve downloaded won’t be running.
Android has a hidden feature, Safe Mode, you can use to correct issues caused by a defective or corrupt apps by uninstalling them. There are some annoyances, and it’s not necessarily consistent from device to device, but it can save your bacon.
It is built into Android, and all devices should have access to it, but not all OEMs will make it accessible in the same way. You will need to hunt down the process for your device when the time comes, but there are a few things all devices have in common.
There won’t be a switch in the OS to get into Safe Mode.
HERE`S WHAT YOU NEED TO KNOW ABOUT SAFE MODE
When to Use
Force Close Loop - can result from the app continuously opening itself, thus rendering the device unusable. You can`t uninstall it because you keep on getting the FC message. If you just reboot your phone the FC still persist.
With the Android platform featuring the loose controls that open-sourced dictates, occasionally an app can cause your device to become defective. This can be really annoying as it could mean that you’re unable to get your device to turn on fully so you can delete the app. When this happens, most people would think of factory resetting the device and losing all their data.
Safe Mode means you don’t need to do this as it only loads the preloaded applications; essentially it puts your phone back to factory settings and applications without deleting any of your data or media.
When you boot back up, your wallpaper will still be the default one, and your widgets are going to be busted. This is probably the biggest pain you’ll have to deal with in using Safe Mode. Just remove all of them, and they should work fine when re-added.
Hopefully at this point there are no more of the issues that prevented you from using your phone normally in the first place. If you are still in a boot loop, or the device is still choking on force close messages, you can try Safe Mode again. Just make sure you know when to stop. Eventually, a factory reset might be the better option if you can`t find the source of the trouble.
When you are calling up Safe Mode intentionally, it’s a good tool, but some devices might also boot into it after a catastrophic failure. This is uncommon, but can be confusing for users that are unfamiliar with Safe Mode. Usually in this situation, the device will require you to manually boot back to standard mode because the phone believes an app is causing system instability.
Should you ever find yourself with a misbehaving phone, give this a shot before you resort to a reset. You may find that it saves you a ton of time reconfiguring the device.
How to Boot Your Device into Safe Mode (Galaxy S I, II, III)
1. Switch off the phone by pressing on the Power button.
2. Then turn the phone back on, while it is turning on press and hold the Menu button.
3. Now continue to hold the Menu button until you see the Home screen. On the home screen you see it say Safe Mode on the left hand corner.
Once you’ve removed the offending app, you’ll want to boot normally. To do so, pull the battery from the device for about one minute, then replace it. The next time you start the phone, it should no longer be in Safe Mode.
