Hello,
it is not possible to successfully scan the QR-Code from Whatsapp Web. I almost tried everything, but nothing works. I searched the WEB and found out that obviously all E7 have this problem.
Due to the fact that this feature is very important for me, i would appreciate any help to get Whatsapp Web work.

Thank you in advance

Do you mean you can not use E7 to scan the code or the code can not be recognized with long press？
