My name 4G network has become very slow after December security update. When I removed my sim card and put in another smartphone, everything is fine. When I use other sim card, the problem comes back. Only 4G faces this issue. 3G is fine.
Galaxy A7 2017

When I put the Sims in other smartphones. The 4G works fine.
The problem happened when I received a security update on Thursday night. After the reboot, the 4G appeared but I can't surf on internet. 3G works fine

Hi! I went to Samsung Service in my country. They say it's related to the update. I noticed also many Galaxy A7 2017 have this problem in my country (Ivory Coast). I also notice that the CSC of all these mobiles phones is : UNITED EMIRATES ARAB.
Please, in the next update, fix the modem problem for us.
