May I ask which phone does Samsung 9103 use Guardian 30?

Hello dear Samsung users:

According to your description, the use of security software on the phone does not reduce the security of the phone itself, if you are worried that the phone will be affected by unknown third-party software, it is recommended that you choose to search for the official Samsung App Store (Samsung Apps) when you ** security software. However, because some operations of the security management software (such as obtaining root permissions) may cause the phone to lose its normal repair, please use it with caution.

It is recommended to use LBE Security Master, which occupies a small memory. Like 360, QQ or something, the memory released at one time is not as much memory as it occupies!

Have a good life. Hope.

It depends on what you're doing, interception, firewalls and the like are easy to use! Android optimization masters such as installation package management to optimize memory are good, antivirus or Kingsoft, these are all authoritative, I have tried them all! This phone is very solid.,It won't be because of the installation of a software on this fault.,Don't worry.。

。。。360 Security Guard Antivirus protects privacy better.

QQ software housekeeper killing program is better.

None of them. Those things themselves take up memory. Some of them have bugs.
