Yes they can, and they do. I have a brand new Pixel XL here as proof of that. I've also been posting screenshots of the conversation with Rogers, but the mods keep deleting those. Read back further and you will see I'm not the only one that they swapped out.
I eventually got a new one.. a manager decided this after problems from day one. be they internet connection problems , or not able to phone out/in..
before I had 1-2 bars. no lte... not 3-4 bars , lte on off.... Haven't had internet problems at all.
The explanation made good sense , the first rolling off the line for pre sale people may not have been as good..
This issue is what I was looking for.
I can leave my home (so WiFi is lost) and the phone often displays 4G with no data access (phone and SMS seem to work). There's a cell tower half a kilometer away, so for the last couple years I always get and LTE connection.
I can even go to a location where I would normally get an LTE+ connection, but it will then change to a 4G connection and data does not work (cannot access Internet).
So from the few comments I read, is taking the phone to Samsung the best solution?
I've been having this issue too but very sporadically. I think it happens every 6 or 7 days for me. Samsung Galaxy S7 that I got about 5 weeks ago.
I'll have LTE for a while, then it shifts down to 4G, then I lose all cellular/data connectivity and have to reboot the phone. It happened yesterday after work and the phone started to get a bit warm, but returned to normal after the reboot.
I'm going to keep an eye on it as I installed the latest firmware update last night, so I want to see if that helps or not. If it happens again though I'm going to take it in to a Samsung store and have them look at it.
