Hi to everyone, this is my first post in this forum. I've bought few weeks ago a new device, a Huawei P9 lite. It's brilliant, I love this smartphone. I've only one problem: on my old device (Samsung galaxy s5) it was possible to expand (just dragging my finger on the notify) WhatsApp notifies on the block screen so I haven't have to unlock my device and I could see who wrote to me and a preview of the message. On my new device this is impossibile, both with one finger and with two fingers (I saw this solution on internet but for me it's not true). I searched every type of settings on the phone: WhatsApp settings, Phone Settings, also Notify settings; the result was negative. Have you got any ideas about it? Thank you.
