What is the meaning of com.osp.app.signin?

com.osp.app.signin is an Android package file developed by Samsung which makes it easier to switch from one Android device to a Samsung device. When you get a new Samsung device, this com.osp.app.signin syncs all your apps and data from the old device to the new Samsung device and stores it in your Samsung account app.

This app syncs your data from the Google Account on your old device and transfers all the app data to a Samsung account created in the new Samsung device. The OSP in com.osp.app.signin stands for Other Service Provider.

The Samsung account app is a membership service that provides users with access to multiple Samsung services like Find my Mobile, Secure Folder, etc. on Android devices.

No, com.osp.app.signin is not a virus, spyware, or bloatware. It is a totally safe application that accesses your web application to refresh the data in your Google and Samsung accounts. This app doesn’t spy on your data and it definitely doesn’t sell your data to third parties.

Since this app runs in the background, some users feel that com.osp.app.signin is bloatware. This is completely false. It is a very important app that uses minimal system resources and doesn’t slow down your device or cause any battery draining issues.

Unfortunately com.osp.app.signin has stopped

A common issue that Samsung users with older Android versions face is the Unfortunately com.osp.app.signin has stopped” error prompt or the “com.osp.app.signin has stopped unexpectedly” error prompt. These error prompts give you two options Force close or Report. Most times, none of the two options work.

One way around this is by turning off your Mobile data and turning it on again. You can also disconnect your WiFi and reconnect to the WiFi network. This might fix the issue temporarily but if you want a permanent solution then you need to Force Stop the app and clear the app cache. You can achieve this by simply following the steps mentioned below:

Step 1 – Go to Settings.

Step 2 – Tap on Apps.

Step 3 – Tap on the Ellipsis icon (3 vertical dots) in the top right corner.

Step 4 – Tap on Show System Apps.

Step 5 – Tap on the Samsung account app.

Step 6 – Tap on the Force Stop button below. This will force stop the app.

Step 7 – To clear the app cache, tap on Storage and then tap on the Clear Cache button.

Can you remove com.osp.app.signin?

com.osp.app.signin is a part of the Samsung account app which comes preinstalled on all Samsung Android devices. The Samsung account app is a system application that does not offer an option to uninstall directly, but you can uninstall this system app by gaining root access to your device and then using the System App Remover application.

I recommend users never uninstall a system app that’s not causing problems because it is required for the proper functioning of the device. If you remove the Samsung account app then you might face problems with your Samsung account. You won’t be able to use some Samsung account features and there are also chances of malfunctions.

It’s better to keep the Samsung account app as it is because it doesn’t slow down your device or cause any other issues.
