Handset incompetence P8

i Have Recently Purchased a Huawei P8 , Nice handset from the outside, the phone is Tipped to have been powered by antroid ,Unfortunately everything to download from play store the P8 treats everything as an outsider, For e.g i downloaded call recorder(various) but some wil record 1st and 2nd call then thats it.<br> Truecalled doesnt work-Mp3 video converter niks-None of the dstv remote app-whatsapp messages wil only flock in once u open the app if you ignore it you wont notice if there are new messages ,once opened u see the icons on top.<br> Cant Huawei just copy staff from Samsung - i have a Note 4 and S4 mini all the app i download works perfectly the oncve i mentioned even works on cheaper phones like AG-Hisense and LTE .Huawei P8 is just about looks nothing special the only feature it came with that works is battery safe app.the rest like to camera ooohooo at night night mare.<br> Took this on contract i dont know what todo now, i feel like the company still owes me a phone for what im paying.its like i drive a Mercedez Fitted with a No name engine..
