for those who have problem with monkey test, android system & time service malware/adware problem, there is one solution without installing anything or root.

i have a A850+ with "乐安全" installed by default, cannot be removed. But you can use this app to freeze the following to solve this problem:
1) all monkey test app
2) all time services app
3) all android system app (there is one original android system and one fake android system)
4) and all other app that you think is suspicious

after that, block the permission of the above apps for switching on wifi/data/sms/mms/call

then problem solved!

hope this can help A850+ users. I googled many times but there is no single solution that works for me.

Hi, may I know what is the use of all monkey test app? Thanks.

Does Lenovo A850+ have Bluetooth ?

monkey app auto install apps and eat up space.

So it is of no use then.

yes, it is of no use, but it is unremovable.

Even with root?

yes, for my case, even with root.

Perhaps you could freeze the app instead.
