Having an odd series of issues that might be device-specific (Pixel 3), but definitely isn't a problem with my hardware, as that was recently replaced and had the same issue.
Basically, what I see is:
- For 1-3 days after a reboot, the phone works perfectly. Data works as intended. Calls work as intended. My office area always sits on full bars, LTE.
- After a few days, suddenly I have no ability to make calls...but I can receive them fine. If I try to call anyone, it just sits on the dialing screen for 1-5 minutes and then hangs up or dials. Inbound calls are instantaneous and there are no data issues.
- When the dialing issue occurs, if I watch the signal meter, it will be full bars LTE, then 3G, then H+, then it will either dial or will briefly say there's no signal and hang up...the moment it hangs up, it goes back to LTE and data works fine again.
- Either rebooting the phone or turning on/off airplane mode will fix the problem for 1-3 more days.
- This issue happens even if I switch over to wifi calling and am on good wifi signal, which makes it even stranger!
- I've reinstalled and updated LOS a few times since this began and issue persists. I've tried with wifi on/off, wifi calling on/off, different locations, etc. I even briefly tried the official Google dialer app, as I had been using the stock LOS one. No change.

This happened two times, once where I had full five bars with a HSPA connection and at home more often where I have two bars with an edge connection.
What happens is, when I get a text message, I will view it and then once I reply, the signal will drop and I won't have any signal, and have to wait for the phone to reconnect.
The same has happened outside with full service.
At home, I have wifi calling enabled and sometimes that will even drop and I will have to wait for wifi calling to reconnect or for the phone to gain back reception.
Is this a common issue? I have the ota radio on it, (not flashing any other radios, due to the fear of bricking), and running on Cyanogens 6.1.1.
Edit: This tends to happen a lot, when I get multiple messages and reply to each other quicky. I do about 6k messages a month and its getting annoying having the phone lose/drop signal when replying or receiving messages.

Does this happen when you use the keyboard or the phone in landscape? I found out that if you cover the top party of the phone just above the camera with your hand the wifi completely drops. Turns out its the same antennagate as iphones but only affecting wif (so far). I actually can't use my keyboard on wifi because right away after putting my left hand on the top of the phone to hold it in landscape my wifi drops from full to either 1 bar or completely turns off and switches to H or 3G. If you're having the same issue then post back.
Yes, I actually do have the same problem. I don´t think there is a solution for it is there?
I'm seeing the same problem withnmy g2, running cm 6.1.1. I have a case on my phone as well.
i am having this problem when i turn the internet on. Happens instantly.
I was having a similar problem, running cm 6.1.1. I flashed pershoot's kernel and have had better reliability during my two days or so of testing.
I've had 'similar' issues. Its rare that my signal drops completely but when I have the phone open in landscape mode and am sending a text using the hardware keyboard, my signal does seem to drop by 10-15db.
I had the same issue with the stock ROM as well.
Although this is not a solution, I have noticed that the signal isn't affected as much if you keep your hands on the back of the phone 'low', as in my index fingers sit below the camera on the back of the phone when texting...
I've had connection problems ever since I updated the radio. My signal before that was great, and so it was at home. Ever since the update, I go from 2 bars of HSPA to Edge, which is pretty frustrating.
At work, my signal was great and never drops. But today I've been going from GSPA to Edge to 3G over and over, which has me really annoyed.
Edit: Also, I tend to lose connection when I receive an MMS, not a regular text. When I get a call and I don't answer, I lose signal completely, which has caused me to miss voice mails.
Here is a problem I've been having off and on with both my Nexus and my Note. I need to switch to my focus for a while and see if I have the issue with that, but generally when I'm at work where there are many areas where there is little to no signal and sometimes if I'm in that area for a while I'll see my phone switch to No Service. Which is fine, but sometimes too long and it'll just go to Emergency Calls Only mode. There have been many times where it seems like if I'm not in that long enough it will come back out, but for the most part it seems like it will stay in Emergency Calls Only mode until I switch airplane mode on and off. I'm using Franco nightly 180, CM9 2012-06-09 nightly(time to update that soon), and the UGLC1 modem with matching RIL obtained through GetRIL. This is an issue that drives me nuts. As I said my Note was doing this a lot too. It seemed like once I switched to one of the newer ICS modems my Note would always come back from switching into this mode. Nexus it seems to be hit or miss. Any thoughts? I don't know if it's just a sim card issue or not. Also there have been times where I'll be in Emergency Calls Only mode, but the network settings will still show a GPRS connection and the about will show that sometimes I still have the data network connected which I've been able to use.
I have an annoying signal loss problem that has been on-going since 4.4, seemed to get a bit better with 5.0, but is bad again with 5.1. At random intervals the phone just loses all signal, as in no bars at all (just an empty triangle), and not even a provider showing. It does say "Emergency Calls Only" in the titlebar, not "No Service", suggesting it actually has signal. This is exactly what it does with no SIM inserted, but I have tried different SIMs to no avail. Eventually it does come back again by itself, but restarting the phone always fixes it straight away.
I can also trigger this behaviour by making a call. Sometimes it works, but sometimes as soon as the call connects, the signal does as described above (so naturally the call drops).
I have googled this for hours and found some problems that sounded similar, but no suggested fixes made a lasting fix on mine. One suggested fix was to clear cache and data for the "Phone" app, force stop, then restart. However, I noticed I have 3 apps labelled Phone. Is this normal? I did the clear/stop/restart on all of them, and that possibly helped for a while, but it started doing it again.
Has anyone seen or heard of anything like this?
the network problem is very troublesome. I now use two phones, one specifically for calls, and one this X ZL. Mine has a bit different problem. it doesn't catch good signals, and while on calls, it automatically loses signals. the call quality is also poor, i tried different sims, but to no avail. my 4 year old Samsung champ gives loud clearer calls on the same sim on the exact same location at the same time where my ZL fails to deliver. i wish we could change the hardware network module

Hey! My wife has a t-mobile G3, stock non-rooted. It's running 6.0. She's had it for a year, and it's been fine (other than some wifi issues here and there). But in the last few weeks, she can no longer make calls.
The weird thing is the calls do "connect", but there's no sound either direction. For example, if she calls me, my phone will ring, but when I answer there is no sound either direction. Both of our phones show the call timer counting the seconds, as if they are both connected. If one of us hangs up, the other phone gets disconnected immediately---so the 2 phones are DO connect with each other, but no sound can pass. This happens with every number she calls.
I would have thought it might be a network problem, but she did a factory reset and it worked fine---until a few days later when it broke again. So I'm thinking it's software. Sometimes her phone will work for a few hours, but then it will stop working for a few days.
I've tried turning ON/OFF bluetooth, wifi, data, & wifi calling. I've tried changing to 2G network. I've tried different sound/noise settings. No change.
Any ideas?? Thanks
Hello everyone,
I have a Xiaomi Mi 10T Lite which I use as a secondary phone.
I'm experiencing a serious issue which happens randomly during the day:
all of a sudden, especially after long sleeps, the phone seems completely isolated from the mobile network making it impossible to send/receive calls, although showing data coverage.
What I noticed during one of this episodes in the #*#*4636*#*# menu is that the phone is trying to connect to the preferred network NR/LTE/TDSCDMA/GSM/WCDMA.
Switching that to GSM/WCDMA/LTE (PRL) revives the connectivity.
Any idea on how this can happen?
Thank you
I too am face the similar issues. I am running PixelExperience 12.1. I use two India SIMs with WiFi calling support.
As you mentioned, after long sleeps, the phone is not able to make calls or connect to receiving calls. Sometime, the call gets disconnected as soon as we answer and won't be able to call back. If the phone connects, the call is completely silent. Disconnecting and calling back works sometimes but most times, call doesnt go through. Putting it on flight mode and back sometimes makes it work. Sometimes restarting makes it work. Either way, its really frustrating.
I tried look at logcat output but I am not able to figure out what is going wrong because of the volume of things happening at that time.
Which is the OS version and firmware you are on? Stock MIUI? Or custom rom?
