    Hi! I have Asus Zenfone Selfie (ZD551KL) 3/32 Snapdragon 615 Adreno 405 with Os Lollipop (now). I have a problem on the network, ie can not use Lte only / 4g only on * # * # 4636 # * # *. I changed it to LTE only and the network instantly lost, if I change to LTE / GSM auto, network rarely 4G, this never happened before, this happaned after I upgrade the os to marsmallow, I have try anything
    I wipe the data, do not solve the problem
    I flash back , do not fix the problem
    I change to the savemode, do not solve the problem
    the Network settings, such as APN, operator, prefered network that has been converted to 4G instead produce the same problem,
    I the lost network, now I can only use network h + / 3g , very slow to play game, sorry for my bad English

    Please help,
    Thank you

    Check with your carrier. They can set the phone up correctly, and tell you if there are any temporary network problems.
