Hello, I am Spanish, sorry for my poor english. I have a Meizu PRO 5 with Flyme 5.1.11.0G and with base version S33_M86_20160406_CHNOPEN_MZ036 bought in Spain and in version G. After updating the firmware to that version, I have a series of problems.
The first is that Opera Max is like a virus in my opinion. Since it was activated, if I use the quality of the cover is not good, but it works. If I disconnect Opera Max, both in permissions (without root) and in power or background applications, the coverage is reduced so much that I lose it.

After proving different sim cards, different telephone operators and different places and those cards in other mobiles. I can only think that Opera Max is the cause of everything.

The second, the application of Music that opens alone much as it takes out the boot, power or permits it continues to run, but ... I never use it or open it.

I know that with root access these problems would disappear, but I have my reasons for not being root. And as a normal user, are two important problems, especially knowing that Opera Max makes the battery consumes 15% faster and its use slows down the system by ram loading.

I also know that the frequency of telephone networks in my country would have some problems, mainly with 4G, but it was very evident that since the activation of Opera Max the terminal works worse.

What is your opinion? Thank you
