Samsung mobile phone gt 19220 SMS

According to your description, if you need to download a third-party SMS software application, I suggest you try:

1. Download and install using Samsung App Store.

Note: Some Samsung mobile phones do not have a built-in Samsung App Store in custom machine. You can download and install it according to the following steps:

1) Log in to "content.samsung.com" with your mobile browser.

2). Slide the screen up, click the Samsung App Store, click the download Samsung App Store button after entering, and follow the prompts to install.

Note: You can also visit /support/html/appstore/ through a computer browser, then scan the QR code with your mobile phone and follow the above steps.

2. Use the browser in the mobile phone menu to surf the Internet and directly search for the required software to download and install (download the Android version in apk format).

3. Download the installation package in APK format with the computer, connect the data cable and transmit it to the mobile phone, operate the mobile phone to find the installation package in "Applications-My Files", and click the Install button after running.

If it cannot be installed and used, it is recommended that you try it as follows:

1. It is recommended that you uninstall and reinstall the software.

2. Unknown source is not open: Set-Security-Unknown source check box, and then try to reinstall.

3. If other third-party software can be used normally, then only this software cannot have compatibility problems with the mobile phone system.

4. Update the mobile phone system version and then try to install it.
