Exactly same problems. I had before this problems, and I still have. New sim card didn't change anything. Also sent phone on service didn't change anything. Very good phone, but I was thinking that mobile phone is for making calls :) After updating phone 5-6 times with updated firmwares, still same problem. But it is very interesting, this problem are present and then just go away for maybe 1-2 months and then again and again,...

Do you have a dead spot in the area(s) where this happens?
Nope... As soon as i restart the phone, the connection is back on track... Close to the window in my house it's 4G/LTE, inside the house it's dropping down to Edge... But like i said... When i have the issues, i have no cell reception until i restart the phone...then everything is back to normal.

I recently set the region to europe with the same result... Just yesterday i flashed it to france (even though i'm in germany) and until now: no issues... Keeping my fingers crossed...

Edit: tried "customized europe" and "france" as regions... Same result :(
Next step will be custom rom and the hope that this bug will we gone.

I have the same symptoms exactly (though much less now). But that is also around a spot where LTE is borderline (some - 110db). My guess is it's related to this weak 4G signal.

have you tried a custom rom already? or anyone else who got this issue? would be good to know if it is resolved by flashing a custom rom.

edit: i just saw that via xperifirm there is a new firmware available for germany (52.0.a.8.83/r2b) i´m gonna give that a try now and see what happens.

Edit2: same problem as before..
For me, it seems like the mobile phone is not able to switch back to another network (edge for example) if the reception on LTE / 3G was too bad... It just stays that way with no reception.
In may case this happens mostly when i'm at home... And after about 1 or 2 days.

In my case it used to happen every 2-3 days until some 5 months ago, almost always at home where I have an almost dead spot for LTE. Then it disappeared completely for some 4-5 months after an update. Then reemerged with latest fw, but only happened twice in one month, and once it was - curiously - only for data, not voice (go figure!). So no intention to get custom fw. I have a widget (Cell Widget) that tells me at all time the status of my network.

Once or twice a month would be alright for me.
I really need to get this fixed as it is really annoying and i really wonder what strange circumstances have to come together for this to happen... If it was a regular bug more people would complain about it... But it has to do with provider signal strengths ans such things.... Like i said before: i had this with another xz2 compact as well i've returned that because i thought it was defective.

Edit: strangely enough: as it seems this issue seems to have stopped or has dropped to a minimum...
I don't know why but within the past few days this issue has stopped to exist.
I haven't changed anything lately so it is either cell carrier sided or somehow otherwise unexplainable.. But i am happy for now and hopefully will be in the future.

Had anyone any luck with this? I am having the same issue. My provider is Telekom Hungary. It is really annoying.

Nope :(
All i can say is that it is an issue with switching between different networks (2G/3G/4G)
I'm on holidays in france now where i'm constantly at 4G+ and i don't have this issue at all!

Even though the reception is not ideal, i'm still on 4G+ but somehow at home if the signal is going a little weaker i'm switched back to a slower network and THEN the problem occurs again.

Edit:
For me it would be interesting to know if someone had this issue first, then used a custom rom and the issued was gone... Any chance anyone experienced that? If yes... Which rom was used?

Sometimes no network or weird switching between 2g 3g 4g but having it since my nexus 6 years ago
Either Qualcomm ****ed the modems or the provider in germany are ****

True that... I am on German T-mobile/Congstar with this issue.. No idea about the other providers though

Even if it is a bug in the modem, this is a closed source hardware piece where only Qualcomm can do bugfixes. :(
I just wonder why so few people complain about this issue?! If you read comments on amazon.de for example most of the users seem happy and content don't seem to have this issue.
Like i mentioned a few posts back... Maybe there are different versions? But i have tried 3 different xz2 compact and all of them were affected

What amazes me is that both my old XZ1C and my wife's XZ1C work just fine in the same space where my XZ2C stumbles occasionally. (We are on different providers...)

Are the modems even different on the two phones?
