HUAWEI Ascend Y3II Dual SIM only view mode vs full access

Options

I have only wiev mode with this smartphone (HUAWEI Ascend Y3II Dual SIM). at connection with Yeam Viewer.. What's the reason ?

Is there a way to have full access to this phone ?  Is there any workaround of this problem ?

I've already use Team viewer with the other model of Huawei and thre wasn't any problem.

I ask for your help.
