Been browsing the site on my phone and it seems very useful to me tho. jus sharin with u guys.

Good news T-fans pending the time of Nougat 7.0 release on all previous the phones released by Tecno mobile, i have just discovered a way to enjoy split screen view on your device without lag. All you need to-do is just to download an app called Multitasking Pro or multitasking free version. this app will enable you to experience the same view display on Nougat just like L9plus & CamonCX, very simple and easy to use no crash or freezing of device. I have tested on several device. Note; works on non-rooted devices perfectly.
