I have M52 & unable no update the inbuild applications, like security patches, by using mobile data.
But the same is getting update with wifi connection.
Though other applications on Google-play store are working with the mobile data.
I bought this in Aug, 22.
On first update in Aug I had to use wifi connection and now in Oct again tge security patche is not updating with mobile data connection, but with wifi it is updating.
