Samsung's mobile phone message was forwarded, but the other party did not receive it. I also uninstalled 360 software.

According to your description, it is suggested that you follow the following methods for reference:

1. I suggest you go to Settings-Applications-All-SMS-Clear Data.

2. Do you have mobile phone security guard software or some third-party software programs installed in your mobile phone? If so, try uninstalling it.

3. It is recommended that you restore the factory settings of the machine, as follows: Setup-Reset-Restore the factory settings (however, since restoring the factory settings of the machine will lose all data in the mobile phone, it is recommended that you back up important data such as phone books, videos and pictures in advance).

4. It is recommended that you try to upgrade the firmware. (Settings-About Equipment-System Update)

If there are still problems through the above methods, please bring the purchase invoice, maintenance card and machine to Samsung service center, and the engineer will check and deal with the machine.

Samsung knows to provide you with high-quality solutions and answer your questions attentively, hoping to get your satisfactory evaluation.
