[SOLUTION] Wifi & mobile data problem

Hey guys & gals. I've been having a problem, and I think I may have found a solution.
History: I had the G2, the wife had the Nokia E73. Her phone sucked (obviously). I had been trying to get a fix or something for her phone for a while. The last step the TMO rep told me to do was to get a “new 4G SIM card” for her phone, and that my SIM card was “old and should probably be replaced as well.” I did this but the problems continued. After hours on the phone, Customer Loyalty sent me a Sensation for $75 plus a $50 MIR. The wife doesn’t like the touch-screen only, so I un-rooted my G2 (running CM7 nightlies) and gave it to her. She loves it. Happy Wife, happy life.
Problem: Ever since I got the Sensation, I’ve been having a problem with the Wifi and mobile data (MD) connecting and switching between them. This problem suddenly started happening once I un-rooted the G2 as well. No matter what kind of router I tried to connect to (work, home, open networks in the public) they would connect but never give me any kind of internet access. All of my other wireless devices can connect and access internet just fine, but the phones cannot. Only upon a fresh reboot would either phone connect and have access to Wifi. If I left the house and came back, the Wifi would connect but not have any access, and would keep bouncing between Wifi and MD and neither would give internet access.
Solution (that works for me):
1. Put the phone into airplane mode
2. Enable Wifi only
3. Once connected to the network, disable airplane mode to re-enable the cellular radio
And that’s it. I tried the ‘toggle ciphering’ thing that someone else posted, but it didn’t work for me. Now the phones work flawlessly when switching back and forth between Wifi and MD. I can leave the house and come back, and everything is fine……….. until I have to reboot. Upon reboot, the problems start all over again. If I repeat the above steps, everything is fine until the next reboot. I've been testing my theory for about a week now, and everything holds true. I'm not sure why this is being caused, but I have my suspicions. I'm no expert so pretty much anything I try and blame for the problems is pure speculation.
Again, this is only my experience with this issue. I have been reading a lot of posts about data issues and I hope this can help some of you.

[Q] Network Signal In and Out with Reboots

I searched and did not see anyone else experiencing this issue. I have a Black 32 GB stock rooted. It worked fantastic for about 2 weeks and then all of a sudden I noticed the following:
Day 1: No SMS received. I was on WIFI and had network signal in the notification bar but did not receive SMS that were sent to me.
Day 2: No Cellular Signal. I looked at the APN and it had disappeared. I attempted to add it again and reboot the phone and it wouldn't add. The phone began rebooting on its own and continuing with a bootloop after running for about 10 seconds it would reboot again. It did this throughout the day. I called Google and they had me do some soft and hard resets. After the soft reset the phone would connect right after startup then disconnect after 2 seconds and reboot itself. I hard reset the phone and relocked the bootloader and reinstalled factory recovery and it is still doing it.
Google has given me authorization for an exchange but I was just wondering if anyone had any ideas because I'd rather not be without a phone for 2 weeks.
BTW I am on Straight Talk

I had a similar issue
I had a similar issue. After a month of functioning normally, my Nexus(rooted using CFroot, stock ROM, T-Mobile) lost the ability to get reception. First, it showed network signal, but cell access was not functional. A few hours later, bars dropped to zero, and it seemed like I could only get reception in the strongest signal areas. I would get signal sporadically when driving, but never when I was stationary. The phone never had problems with rebooting though.
After spending a day trying to fix it, factory reset, relock, flashing a factory image, I called Google, and they warranteed the phone.

It just seems so much like a software issue as opposed to hardware that it surprises me they are willing to warranty it... but I guess I'm not the expert.
How long did it take you to get your replacement phone?

I got a replacement phone pretty quickly. The phone shipped the day after I ordered the replacement, but YMMV.
Why do you think it was a software issue? The problem persisted after I switch back to a factory image. The replacement phone, running the same software does not have the same issue.

That makes sense that it was a hardware issue. I guess it could be a faulty radio or something. I'm glad to hear you got your device shipped so soon. Did you end up having to pay shipping?

I ran a nexus 5 for about 4 days and went through two of them both having issues holding a signal. Both phones would start with LTE and then drop to 2g go to 3g and then 4g back to no bars and then 2g and 3g. I was stock all the way and I wish the nexus 5 worked better. It could be a software issue as when I took the OTA to 4.4.2 it became worse. All the areas I was in while this happened were areas that were supposed to be strong for 4g and LTE.
That said I I need a phone that is a bit more reliable even though I'm on T-Mobile. I switched to the LG G2. It has a better antennae and doesn't keep bouncing between modes when in various areas.

[Q] 3G not connecting after screen change

After flashing CM12 on my nexus 5 (D821). I flashed the 20 jan Nightly and everything was working fine untill i update to the 22nd jan nightly when my 3g simply stopped connecting or had very spotty signal, i didn't give it much thought at first thinking it was a nightly problem but after one week i reflashed stock lollipop, locked the bootloader, even tried kit-kat and the problem is still there. Before flashing cm 12 2g/3g/lte switching was working perfectly for about one year.
So utill now: i flashed different stock rom's, different kernels, radios, custom roms and nothing worked. When i tried switching the sim with another one from the same network, 3g worked on the other phone so i doubt that the sim is defective, but on my nexus i had the same connectivity issues. I also played with the *#*#4636#*#* menu and managed to get 4G working again but only in CDMA mode and I cannot receive any calls or texts, but the internet connection is working, 3G also connected at some point but the signal was very poor.
I am lost now, and also desperate because edge is too slow for anything. What confuses me though is that this seems to be a software issue since the cause was me flashing a different ROM but all the signs point to a hardware issue.
Can anyone plese give me a second opinion? Is there any fix for this? (Also i recently went to my network's service to replace my screen assembly, could also this be an issue? the issue appeared about 2 days after getting it back from them, also about the same time i flashed cm12)
Thank you for your time.

Also another thing i just noticed:
I opened my phone's back cover and the writing on the frame covering the motherboard says D820 and in the bootloader my phone shows as D821. Is this common for every D821 model?
I started to wonder if i got all my components back from the phone service... Although it's highly unlikely that they mingled with the motherboard since everything that i had on my phone was still there (custom ROM and all my personal info) maybe they switched the antennas...

Is the antenna connected?

Im going with disconnected antenna as well.

Would you rma this pixel?

My pixel (from google not verizon) has been having lots of LTE connection issues on verizon. It will get stuck on no lte connection or stuck on 3g. Toggling airplane mode sometimes helps and it will then connect to LTE, sometimes I have to reboot the phone and then it connects to LTE.
I've already completely restored the phone to stock (i have flashed both slots with the factory image from google, pretty much the same as these instructions: http://www.droidviews.com/restore-google-pixel-xl-to-stock-flash-factory-images/)
Even after that I still have LTE connection issues, pretty much once every other day I am restarting the phone to get it to connect to LTE. It was working fine and then just one day it randomly stopped connecting to LTE totally. I thought maybe it was the rom I was on, which prompted me to restore it to stock. It could connect after that but its pretty flakey.

did you check with verizon first?

I had the same problem. I bought my phone off of the Google Play Store and am using it on the Verizon network. The phone will randomly lose 4G and won't send or recieve SMS/MMS messages. This seems to happen more often when I am moving quickly (car, train, etc). Maybe it has something todo with tower transitions. I tried everything: factory reset, reflashed the stock images, relocked the bootloader, got a new sim card, talked with a level 2 tech at Verzion who told me he reset my account. Last week I contacted Google and they did a RMA. The new phone still has the issues. I went back into Verzion and they told me there was nothing more they could do on their end. They said to convince Google to do another RMA but with a Verzion Pixel. I have my fingers crossed that Android O fixes the issues, but I'm not holding my breath.

Your mom.

Same issue. popping sim card out then back in is a quicker way to get 4g back than restarting.

Various issues with Verizon V50

Folks,
I am curious if anyone else is having some of the issues I've been experiencing. I am not happy with this phone overall. I am having lots of problems with it:
- HotSpot - I originally found a hotspot issue with this phone, that took them a few weeks to resolve. But even after they've resolved it, I have other issues. The biggest is that after some period of time, my laptop will not get data through the phone. I've tried different laptops. The laptop shows that it is still connected to the phone's wifi but no data. The fix is to disconnect the laptop from the hotspot and then reconnect. This is an issue for me as I use this for work to provide customer demos. In order to get to my lab, I need to make 2 VPN hops. (1 into work and then 1 into my lab) When I disconnect and reconnect my laptop the hotspot, I have to go through all of that again. This problem only affects the connected device. So when the laptop stops "working", the phone can send/receive data just fine. If I kick off a speedtest, it looks good.
- GPS issues - The GPS accuracy seems to drift. Lots of times when I am using Waze, it has me in completely different places going in different directions.
- Phone issues - I drop calls often. I believe (but not 100% sure) that this happens when it uses wi-fi calling. (I just turned off wifi calling, so I'll see how it goes)
- Phone issues pt. 2 - Sometimes I get an error message "Mobile network is unavailable" and I cannot make or receive calls. A reboot fixes this.
Been a huge LG phone fan since the G2 (even loved the G4 despite the bootlooping), but this phone makes me want to throw it against the wall

Hello! You may want to turn off the default 5 minutes timeout. I think this is the problem. Check attached screenshots.

It's not turning off as I have the timeout set to Never Turns Off.
Thanks

I am having the same issue. People have told me that they tried to call me but phone never rang. It also rang on their end and then went to VM. So people assume that I got a missed call but I didn't.
I also at time show no reception. I would have to go into auto connection to network and then it starts working again.
This is really screwing up my business.

I have the same problem with missing calls (never rings) or I can't make a call. Also, sometimes I can hear the other person clearly but they can't hear me or I sound terrible on their end. However, I have an LG V30 (lurking here because I'm looking to buy a V50) so I don't think it has to do with the phone as much as it's Verizon's coverage. For the last 8+ months this issue has gotten worse in my area. I was thinking it was the phone, but I think it's Verizon.
Edit: Just in case it matters, I'm still on the original grandfathered UDP

I must clarify that this issue only pertains when I am home. For some reason, when I loose Verizon connection because the wifi is being used or a dead spot in my house. The mobile connection won't come back on until I manuallly have to reconnect.
I used to have Verizon fios at home and never had issues before but as soon as i switched to optimum this issue might be because of that.
Outside of my home, I don't have any issues with missed calls.
