I haven't downloaded anything from my Samsung I9 100G. I use the 4.04 system, but I haven't received any short messages, such as 10698009558.

According to your description, I suggest you:

1. Check whether the third-party software with interception function similar to 360 is newly installed on the mobile phone. It may be that the software is incompatible with the mobile phone. I suggest you uninstall it and check whether the mobile phone is back to normal.

2. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (Settings-Privacy-Restore Factory Settings).

3. If the problem still exists, it may be that the hardware of the machine has failed. It is recommended that you send your mobile phone to the nearest Samsung service center for testing and maintenance. For more information about the service center, please visit:

I hope I can help you and wish you a happy life!
