Greetings All,
Got my Xoom back from its 4G upgrade last week and I have been noticing some issues with connecting over the 3G/4G network now. I use pocketcloud to connect to computers over RDP and when connected over WiFi networks, it works fine (computers connected to networks other than one I am connected to WiFi on), but when using the 3G or 4G connection on the Xoom, there is a network connection error. I tried it out on my incredible and it works just fine. Also, sometimes I get an error "cannot update" from the engadget app.
Also, the new market would not install some of my apps, like ThinkFree Office for example, I worked around it by using the web interface of Android Market on my computer and it worked fine.
I sent in the Xoom completely reverted back to stock 3.1, I recieved it with 3.2.2 stock. I cleared memory after I got it back and did a factory data reset. Not rooted, and no other modifications have been made.
I'm at a loss as to why some connections are causing the network to flake out.
Regards.
I read on here that some of the app installation issues were due to the possible change in pixel density that took place with the upgrade but that is something you can change back if you root.
I'm noticing the same exact issue and have no idea what is causing it - let's see if together we can figure it out. It's extremely flaky so far.
I got my upgraded Xoom back today and noticed the exact same issue. It wouldn't activate on the setup screen and prompted me to reboot. After reboot, it connected to 4g just fine and showed the 4g icon below.
I then went into the market to install my apps. It installed Thumbkeyboard just fine but when I went to install others, it stopped at 8.03k on the download. Did this for every app i tried.
I turned on wifi, connected to my AP and the downloads worked just fine. Even tried a couple reboots before doing this and it didnt work.
My 4g signal is about 75% so it's strong.
Very strange...
Power off
Remove SIM.
Put SIM back in
Power on
Done. Worked for me.
I take it back, still having all kind of issues.
just got mine back this morning, and it wont connect to anything! no 3g, no 4g, no wifi... nothing. WTF!?!?! restarted, pulled sim, etc...
going to do restore next and see what that does.
Same connection problems
Got my LTE upgrade back.
When I am at work I cannot update Touchdown from inside the firewall (not sure why) so I flip back to Verizon to refresh by shutting down the wifi. When I do, I noticed that the xoom would drop the connection (three bars) and then not reconnect. When I try to turn on the wifi it stays grayed out and neither system will connect until I reboot.
Went around with VZW tech support, they reported that the unit was registering on their network but not connecting. Sent back to Moto for further testing, got the unit back (they reported it was a software fix, no other data) but the unit continues to have the problem.
Stock 3.2.2 xoom with LTE
Any suggestions appreciated....
Has anyone been able to resolve this issue?
Hello, I am still having all kinds of connection issues after I received my device from Motorola. After a reboot the xoom will connect to the Verizon network but If it stays idle for some time, I lose the connection and it will not connect until I reboot the device.
sent it for replacement
I had the same problem. I had to send it back once for 'repair' (no improvement) before Motorola replaced the unit due to an undefined hardware problem. Keep calling or go to a store.
I had something similar when I got my Xoom back. Apparently the geniuses at Verizon never added the SIM to my account. Took multiple calls/emails to get it corrected. Once someone realized it was missing it was corrected in about 10 minutes.

In your case did you have sporadic connection or, without the SIM number, were you completely unable to connect?
BTW, I missed this thread when it was fresh (as I was traveling) but I've had the exact same issues since the LTE upgrade. When it happens, the only way to reconnect is to reboot.
I used to be able to get it to reconnect by switching airplane mode on and off. Sometimes I had to reboot. Friday, even that did not help. I was furious. The next day, the update pushed out to me via wifi. I guess the servers recognized me as a customer again even though I already had a 2 year contract. Some people got the dataplan because they don't use wifi. I love the shortsightedness of the people who come up with this... not.
At least I haven't gotten disconnected since the patch was installed.

I had to unroot my device for 4G to start working normal.
Im on stock Rom[MF9] + rooted and got the phone officially unlocked through Sprint recently.
Since then, the phone hardly connects to 4g, its almost everytime connects to 3G only and speeds are very bad!!
I tried ##72786# reset and prl/profile update from system options and it hasnt been of any help.
Please suggest any way to troubleshoot this.
Change the mobile netowkt to just CDMA and see if that helps with 3G speeds.

That worked to stabilize the 3g speeds.
But still wondering what went wrong that my phone even wont connect to 4g anymore!...
I'm checking couple of options since yesterday. If anyone got any suggestions other than resetting it to stock, please let me know...
you might also check and make sure that the unlock didnt clear out your LTE apn's......its not common but ive seen it happen before.
The issue is finally fixed and data speeds are back normal. I tries couple of things and not exactly sure which one fixed it.
Started off with cross checking all the entries of ##DATA# with another S4. --- this was ok
But noticed the APN kept going back to eHRPD.
I then got a APN manager app from play store and forced the APN to point to the correct profile and also cleared the LTE_available file in ##DATA#.
Once this was done, the phone connected to 4g shortly and is now working normally.
I'm in Japan for a couple of weeks for work and signed up for the Japan pack that Sprint offers. I spent almost an entire week working with Sprint support ( ) trying to get data roaming working properly on the phone without much luck (voice and text worked great), but yesterday I lost all connectivity but wifi. Figuring I must have changed something I shouldn't have, I saved everything I could and did a hard reset on the phone.
It still won't connect to any networks. I've re-downloaded PRL and device configs over wifi in the settings but it doesn't even attempt to connect to any wireless networks, or see any for that matter.
I have 2 guesses here but I'd like some kind of confirmation here before I take any action.
1: Maybe my radio firmware is corrupted somehow? I'm not exactly sure how to check it but it just doesn't seem to be doing much of anything. In the SIM status page it says searching for network, but I have no way to know if that's really the case.
2: Since the phone has a Sprint SIM, does it has to be on an actual Sprint network to initialize the networks? (Not Softbank's network here in Japan?) I spent over an hour on Google Voice with them last night trying to get an answer/help but got absolutely nowhere.
The phone is currently all stock but I have no problem unlocking and installing recoveries/software/roms if need be. Any ideas what I can do here or am I just stuck without communication until I get home next week?
Usually the best route is to get a local prepaid sim while traveling but honestly I have no idea what sprint offers for roaming in Japan. Check your plan and see if there is an add on needed.
I'm not alone!
Also THIS IS STILL AN ISSUE!
It worked fine for me last time I came to Japan, about a year ago. This time, I only have voice and text, no data. Right now I'm backing everything up to do a factory reset.
Did you ever find a solution to this?
I'm not sure if you've already done your factory reset, but if you're on Sprint, don't do a reset. The phone can't reactivate itself off of Sprint towers. You have to be in the US when you do the reset. I was stuck with WiFi only for most of my time there because I reset mine.
I never found a solution other than dropping Sprint when I got back to the states. Switched to Verizon and never looked back, though I'm not sure what I'm going to do for my next trip with their ridiculous international rates.
I actually got it working last night.
Factory reset and restore over wifi
Update device config over wifi -> handles activation
Update PRL over wifi 3 times
Now it works
Oh, I'm glad it worked. Is yours on Sprint?
Yes, but I may have spoken too soon. It worked for a few hours and now isn't getting back on data. I think it may be SIM related, since I saw a weird SIM error pop up and rebooted my phone, which led to the data working the first time
They must have redone their activation system since I had my issue in July. At that time there was no way for the phone to reactivate without being on Sprint's system.
As far as the data, that's the same thing I had happen and they were never able to solve the problem. It would work for a little while then stop for no reason. If you find a solution I'd love to hear it though.
I'm wondering if I can flash a different radio or something
So, when I woke up this morning I noticed my cell signal strength icon was one I haven't seen before. I tried rebooting and toggling airplane mode. I also verified that my sim is working in another device. I attached a screen cap with the icon.
Noticed something similar with mine. I had to turn wifi off, restart to get LTE data (verizon) then turn wifi back on. If restarting with wifi on the LTE data doesn't register.
that didnt work for me
update: had to factory reset, looks like verizon doesnt like that essential ph1 wont take all their bloatware, etc. might have to return the phone if this keeps up
My data connection has also become very erratic - and I've lost voice+data (VoLTE connectivity) wholly yesterday. Worked fine with the activated SIM from my HTC 10 from the 31st to yesterday.. Now, not at all, I've not been able to restore it since.
Really don't want to return it, as I really like the phone, but this has nexus 5x issues written all over it for long term use...
Hoping essential can get a certification and an agreement with Verizon before my return window is over (or at all)..
Pretty disappointed in Verizon here.

Same here, another issue is that essential shipped my phone and within a day i had an email from essential saying that verizon certification is still in progress. verizon will probably not certify it with their system unless essential lets them install their monitoring crap all over the phone.

The Nexus 6P didn't have the bloat and worked fine.
My PH-1 works fine including Enhanced 4G LTE Mode.
What do you have selected for network type?
I have the first one selected because that's the only one that includes the various CDMA protocols, EVDO and LTE.
I see the same connectivity that I had with my Nexus 6P.
i have global selected, as it covers everything the phone can connect to. i had the first one selected but it wouldnt show the lte+, just regular lte. i also have Enhanced 4g lte mode on. it just happened to lose service earlier today. if it does it again, ill probably return it after a visit to vzw

I have the same settings as you, I had functional "enhanced 4G LTE" for the first 4 days as well... That ended yesterday morning abruptly, and I'm not able to bring it back.. There's more happening here.. How long has your device been on the Verizon network? Only a hunch - in a few days you won't have "enhanced 4G LTE" either, even though it'll still be checked, and provisioned for it.

Cellular network is not available
After 7 days my phone won’t make calls I can only use data I’m on sprint and it was working fine until today I call sprint they had no answers at all I email essential no answer now I can only use WiFi calling while home and axx out at work
So, upon further digging I found a place to look at some more in-depth stuff relating to signal stuff. I did some fooling around and switched it from unknown to lte/cdma/umts auto (prl) and it seemed to work after a few moments of time. Though it seems have gone back to t he unknown state again but is working normally for me now, so maybe it was changing states and then a reboot?
How I got to this screen was by punching *#*#4636#*#* into the dialer, and went to phone info
I'm having a similar issue. I often lose my signal. I will have the full triangle/bars but no label of the signal(LTE+/LTE/3G/1x/etc....) and no cellular data at all.
The only way I can get it to return is to restart the device. Happens a few times a day, can't be 100% sure why, but it often appears to be when switching from WiFi -> Cellular only.
I have Verizon, I have had a Nexus 6 and then a Pixel XL for the past 3 years, never once had this issue.
I had constant disconnects and lost of service with my Tmo sim. Tried my Xfinity (VZW) sim and it was great until this morning. Complete lost of service. Airplaned mode on and off, connected to old school RTT 1x.... lol This phone's cellular just plain suck for a lot of us regardless of carrier. Not sure if we just have bad phones because apparently there are those who claim they have great service and connection.
I'm having this problem with Verizon. Seems like if I'm on wifi for a long period it only connects to 1x and putting in airplane mode and stuff won't get it to re-connect to to LTE. Only a reboot seems to fix the problem.

Necro post here but chiming in that I have the same problem with Verizon LTE. Happens when I'm moving long distances in car too. Suddenly just drops LTE and only a reboot will bring it back.

You might check out my post from the Oreo Beta thread... I was having some goofy signal issues early on which I've pretty much cleared up by doing what I mentioned here. Someone touched on it briefly earlier but only mentioned monkeying around with the settings, said nothing about picking up a new PRL.
I state this in that post too, but just in case: I offer this with no express intent of warranty, if you screw up your device, it's on you.

I just changed it from global to LTE/WCDMA and I got LTE back almost immediately. Was weird and global had been working for me for awhile now so not sure what happened in the past few days...

I had, right after writing this, tried *#*#4636#*#*
I set it to global as instructed in another post. The next time I drive a distance in the car I'll have to see if I have the same issue that only a reboot would fix again.
Thanks
I had the same issue and I resolved it a little differently than the previous posters. I turned on adb debugging and logged into adb shell and user-disabled com.redbend.app. This stops the Sprint oma-dm service from running. After doing this I no longer have the issue of my device not reinitializing lte after sleep or 3g.
I have essential on vzw but my only issue is my device won't connect to 4G. If I change network to LTE I get full 4G service but I'm unable to make phone calls. Went into vzw store and they told me you didn't get the phone from us so we cant help you. Day 14 fml
On Xfinity mobile, I had similar issues. Great LTE but sometimes calls just don't work at all. I mess with various settings and it'll work for a bit then so again. Gave up and ported over to Sprint for the free unlimited year which is still probably not worth it. Should've kept with Xfinity Mobile. Lol
Don't think it's same issue as ppl lte issue but my s10+ 1tb doesn't connect to the mobile data when u are out of wifi range. I have to either reset the phone ornl on and off airplane mode to get the data back. Seem to work if I manually disconnect the wifi rather than let it out of range.. seem to only happened after last 2 updates. Phone was purchased from Samsung on Rogers Canadian firmware anyone else?

Im seeing the same exact thing with my 1tb pre order purchase. Bought directly from Samsung for Verizon. I also notice terribly slow download upload speeds(4gb down/2 GB upload) when in restart the phone it will go back to 100gb+ down for a while then get stuck at 4gb again. I've factory reset the phone and odined back to asd7... still the same. I had Verizon give me a new sim and do their provisioning on their end but no improvement.
I hope its not the same hardware issue others are facing.
I just sent mine in for repair. Mine would work only on LTE band 12. If it connected to bands 2 or 4 I couldn't get text, mms, calls or the internet. It looked like it was working until I tried to do something. I downloaded Signal Spy and it showed me what band I was on. Once I figured out the bands it dint work on I had to go into the service menu and trurn them off. No more issue except data speeds were so slow! My phone was manufactured in February so I think that has something to do with it.
It's funny, Samsung kept saying it's the network and an update was coming to fix it. It never came. I even switched networks and the same issue.
