PATHETIC DEVICE!!!

So my Huawei P8 Lite Screen cracked and in need of a repair. While its in for a Repair i decided i needed a Cheap phone to use while the P8 Lite is in for a repair. I made the biggest mistake of my life to purchase a Samsung Z2 ... All i needed it for was Whatsapp, Calls and Emails. THIS PHONE IS NOTHING BUT A PIECE OF ****!!!!! whatsapp is out of date, Disconnects each and every single time on Mobile Data or on Wifi, And when you open whats app, It reconnects for about 5Min and then all your whtsapp messages stream through. My emails does not sync unless i manually go into it and refresh. even when i do that, it takes about 5min before it shows anything at all.. No matter what i change the Sync schedule to, IT JUST DOES NOT WOR**** .. OH and the best part, This stupid phone is not even Android. I realize now Why i dont buy Samsung anymore. ever since my over heating S6 Edge. DO NOT BUY THE Z2!!!! ITS WORTHLESS!!! AND I ONLY HAD IT NOW LESS THAN A MONTH!!!!!
