Frequent Random Network Drops

I've seen a number of threads where people post about their device dropping network data connectivity, and needing a reboot to solve it.
My issue is a bit different. Occasionally (I've noticed it 3-4 times today) when I go to send a text (SMS) or to use a data enabled service like Hangouts, that my phone shows no bars at all.. not even just no data, but the bars are grey and there's a red x. I wait about 15 seconds and it reconnects, then another 10 seconds later, the data is live again.
Phone is a private sale and under 1 month old, and all the Stamina functions are off.. I do see that the "Queue background Data" is turned on, but I don't think this should effect, no?
Not sure what digits I should be looking at to know if this might be a hardware vs software issue.. build is listed as .93
Im no stranger to unlocking and flashing, but I've kept this stock cuz it's tight and I adore the battery life.
Suggestions?

check in settings in network and set your network to the one you use , like gm/wcdma /lte , maybe your phone is strugling to find 3g or 4g , try it , who knows it might solve the issue , ty

Been about a month since I posted, and I'm still experiencing this issue. I often thumb my phone on and it's not connected. I don't really mind waiting for the 30 seconds or so that it takes to jump back on the network, but it often means I miss calls, and since it's my business phone, it kinda bums me out to suddenly get a VM notification of a missed call even though it never rang.
Is there some sort of utility that I can use to monitor the network activity to see how frequently it drops, and for how long? I've looked into ones on Play but they don't seem to have a history, just something that shows what data up and down is currently being reported.
Sadly the only Sony store in my city (and I think the country - Canada) has recently closed for good, so I'm not sure how to go about warranty repairs...

I don't have a solution, but I can tell you that you're not alone. I've been experienced the same thing on my Z3C. I sometimes wonder if it has anything to do with the fact that the MVNO I use doesn't support 4G LTE.

Interesting.. Your issue isn't just data, but a complete network disconnection? Im with Fido which is an MVNO under Rogers, but I thought they supported LTE. The issue also persists even on wifi

Yes, it seems to be a complete loss of the mobile connection. When I wake the phone I see gray bars and a red X on the signal strength indicator. Within seconds the phone re-acquires and the indicator goes to 2 or 3 bars. I have also seen it happen with wifi active. The frustrating part is that it doesn't seem to do it often enough to troubleshoot. I'll notice the problem maybe a couple of times a month and there's nothing obviously different about my usage patterns in those instances.

Mine does it at least a dozen times a day. I can only assume this as I frequently miss calls and at least 3-4 times a day I see it happen. =(

Same Problem
Randomly I have no connection at all but after a few seconds everything wents back to normal. Did not have this problem with T-mobile in Germany but with with O2 I have. With T-mobile I had LTE but with O2 I don't, so I guess that's the reason.

Interesting... I've disabled LTE and now have it on 3g/GSM. We'll see how it works moving forward, and I'll post again in a week. Stay tuned.

Service Providers
In the mobile network settings one can change the service provider manually. With LTE enabled my provider has three entries: LTE, 3G and 2G. Connecting two LTE fails, because my provider blocked it in my plan. Having LTE enabled, it often tries to connect to LTE I assume. I switched off LTE and set the provider manually to 3G. Maybe that helps. We'll see.

Interesting.. I have LTE as part of my network and plan... But once I made changes to the settings as I indicated, I no longer receive the network drops I originally experienced.. I might just be missing the alerts, but it seems fixed... #crossedfingers

[Q] Cell reception indicator constantly flips between "no reception" display and bars

[Q] Cell reception indicator constantly flips between "no reception" display and bars
I'm using the Xperia Z3 Compact on TMobile's network in the US.
About 1/4 of the time when I turn on the display the phone indicates that it has no cell reception:
1) The phone shows no bars of reception, and a red X over the bars
2) The lock screen reads "Emergency calls only"
However, within a second or two the phone appears to acquire an excellent signal and I get a full 3-4 bar display. All of the areas in which I use the phone are marked as "Excellent" on TMobile's coverage maps.
This also happens intermittently while I'm using the phone. I'm not sure if it's actually losing the signal or if it's just a software issue. I've never had it drop a call or cut out while I'm talking.
I'm getting only acceptable battery life from the phone (about 25% at the end of the day) despite light usage and conservative app installation, even though this phone has a reputation for excellent battery life. My theory is that this might have to do with the phone constantly disconnecting from the network and then having to re-aquire a signal.
Anyone else had this experience with the Z3C?

Hey mate.. I posted the exact same issue a couple of months back. I was experiencing this exact same issue.
I've had my LTE disabled for about a month now and haven't had a single drop.
Not sure if LTE is a dealbreaker but since my device is a business line, I can "suffer" with better battery life and slower internet if I'm not dropping calls. I've considered trying a ROM with updated radio firmware but figured I'd wait to see what the current Lollipop update does ('ll re-enable LTE once I install it and see if it repeats the same behavior) for my phone before trying a 3rd party system.
Hope this helps

Thanks! Really gratifying to know that it's not just my device. Seems like there's a strong possibility this is the issue since I'm on a MVNO that's only been on this LTE network a few months. I've flipped the device into GSM only mode and we'll see if it helps.

Dumb question how do i flip it into gsm?

Thanks!!!

I'm having the same issue as you have described. For now I've set the phone to 3G prefered. Looks instantly better. Signal strength is also better.
Provider: Simyo (KPN network) - The Netherlands
Edit - Issue solved:
I switched from the Lollipop Baltic ROM to the Lollipop KPN carrier ROM for The Netherlands. The switching is gone for me. Battery life drastically went up.

Any update on this? I just started experiencing this issue out of no where about 2 weeks ago. I'm not rooted or anything, can't afford to due to job security requirements and such.

Verizon range extender problems

Anybody else on Verizon using a Verizon brand extender? A search found one other old thread but no definitive fix. The one proposed fix was to set the phone to 1x speed to force it out of hunting for towers outside and hope that 5.1 fixed the problem. I just got my phone from Verizon, it came out of the box with 5.1, so it would seem they didn't fix it. And I can't seem to find how to set it to 1x. Only from global to LTE. I'm dropping calls, having problems with texts, and Verizon support admitted it doesn't seem that my calls are going through the extender. They said the 6 should be perfectly capable of utilizing this extender. My note 3 worked perfect on it, and as far as I know the wife's note 4 does as well. I get the beep like it's calling through it, just not the signal. And this phone doesn't have a separate icon to show if it's connected, intermittent, or never recognizing it. Is this a known issue and I just didn't search properly? Running 5.1 LMY47E, bone stock. I warrantied the phone, same thing. So this thing is literally about an hour out of the box, no mods. Looking forward to rooting and running some roms but I'd like to know I've got any issues ironed out before hand. That way I'll know any future issues are rom related, not hardware
TIA

Unfortunately there is no fix unless Verizon decides to somehow upgrade the software/firmware of the extender. I'm surprised that Verizon tech support didn't inform you that the extender is not capable of utilizing 4G or enhanced network capability and can only function with 3G or less. I spent a bit of time on the phone with tech support and requested a problem ticket be raised to Verizon engineers to get a definitive answer -their response was that the extender can not do 4G but only 3G. The way I was able to get my Nexus 6 to successfully connect was to turn the "Enhanced 4G LTE Mode" off and then it was able to connect. This is not a nexus 6 issue only but from what I've seen is any phone that has that enhanced 4G setting - my wife's Iphone 6 is also unable to use the extender unless that phone capability to use 4G/LTE is turned off. Surprised you even got the beep as never of our phones get that connection beep unless the 4G/Enhanced switch is off.
I'm surprised (maybe not) that Verizon continues to sell the same Network Extender even though it no longer works with the new network capability or with phones that use that technology. Also brought that up with them during my call but of course that wasn't addressed. I also got no information as to any plans to upgrade the extender firmware but I'm assuming the lack of info speaks loudly.
Again one can never be assured of whether the information they provided me is accurate or no so if you find out differently please post back.
Also, my Nexus 6 is rooted and I have tried numerous ROMs and the ROM makes no difference so that isn't going to fix the issue.
Hopes this helps a bit.

This helps a ton, thanks! I've always known that the extender didn't support anything above 3g, but it's never been an issue since my router took care of data and 3g was plenty for calls and texts. But I was thinking it had something to do with this... I haven't researched any of this new stuff about xlte or whatever it is but I know it seems the phones are changing to support some mods to the network. I haven't paid attention because my town is usually the last to receive this sort of technology. Big cities were going to 4g soon after we upgraded to 3g...
Can you tell me if the pic below is the menu that you used? I can't find any setting anywhere else that specifically says 3g, to try to force it into a mode that the extender understand.

you can dial #48 and the phone will tell you if you are under network extender coverage

The setting that needs to be disabled is on the same screen where you set the preferred network type (actually under the one you are displaying). It should be the next setting following the Preferred network type. It actually has a slider to turn on or off. Now, I'm not running stock but I believe it should be the same or very similar on stock.
Not on my phone or i'd try to include a screenshot. Hope this helps.

Oh yeah, I forgot about that detail. The Verizon tech had me do this. It actually told me I was connecting through the extender. And the call seemed relatively clear. But I could hang up and immediately dial my voicemail or some other number, get the beep from connecting through the extender, but the call would be spotty and cutting out badly. And the tech was confused by this because it wasn't showing on his system that I was connecting through the extender even when the #48 said I was. Strange things going on with this...

I'm not typing on my phone either, to include a screenshot. But I'm looking at it. The option directly under Preferred network type (which I have changed back to the default Global), is System Select. The subtext under that says "Change the CDMA roaming mode". And within the menu, the two options are "Home only" and "Automatic", of which Automatic is the default. Is this what I'm looking for?

Do you have Advanced Calling activated on you phone? Not sure if that is the issue or not but on your Verizon Wireless account you should see Advanced Calling (I believe that is what it is called) under "Manage Products. & Aps" - you should have the option to add it to your account. It is a free service but as I understand it you need to include it on your account for the phone to use Volte and it might not show up in settings if it is not an active service on the phone. Again, I'm only guessing here since I'm not on stock but I do believe I've had the option since I got the phone and I added HD calling right after I completed the pre-order.

I will log on in a bit and look. So are you suggesting that I enable it, or disable it? Is it believed that HAVING this feature is what is killing the link to the extender? Sorry for the dumb questions. Like I said, I've never had to look into the new tower technology before because I don't anticipate getting it in my area. I never thought about it still affecting my service anyway, even though we weren't getting it... figures.

For me to use my extender the 4G enhanced/LTE needs to be disabled. What I don't know is whether that setting shows up on the phone if the Advanced Calling isn't active on the account. If it doesn't show up there might be no way to disable it. I know it sounds somewhat illogical but again
I'm guessing to some extent given that I have it on mine and I really think it has been there from the start.
Sorry I can't be definite with it.

[Q] Nexus 6 Random cellular signal loss

As the title says, Its been better now its worse, my mobile signal disappears leaving me from full strenght to empty triangle without any clear pattern. Calls, data, nothing works so its a geniune signal loss not a software bug. I was on LRX21O > LRX22C > LMY47D > LMY47I and latest is the worst.
I cant remember having this issue on 5.0 but early lolipop is plagued with bugs. Any ideas what might be going wrong and how to fix this? Its really frustrating....
thank you in advance community

I tend to have the same problem, but its only been mobile data for me, I have sprint.

I have a similar issue. When I attempt a phone call in my basement, I get "no carrier available". I can go upstairs/outside and initiate a call, go into the basement and the signal is fine. I suspect it is a radio problem that Google needs to fix. I also cannot send mms with photos-no matter where I am. Pretty darn frustrating for this over-priced phone.

http://forum.xda-developers.com/nexus-6/help/signal-signal-t2959050
General consensus is a software bug. Happens when switching between different LTE bands and different towers, regardless of carrier. Signal won't actually drop, but ASU jumps to 99, then corrects itself. This causes the signal bars to drop to zero, then back up, but signal stays connected the entire time. Would be nice to be able to revise the way that android reads that and not drop bars for it each time. Either that or have the ability to force to a particular band/tower to avoid the switch. Annoying, but looks worse than it actually is.

Sounds like you may have something else going on if you can't make calls.

I have the same issue and it cancel calls even when I'm talking. Before Google's updates for that bug called stagefright it was awesome and without problem but now it seems their update aren't match carriers datas.specially for us in Asian countries because our carriers have no contact with google

I have the same issue as this, and I asked before:

Moto G5S plus always has low signal

Hello. I have a Moto G5S plus using a Verizon Sim. I had a Moto G5+, but gave it to my cousin and got the G5S+. The G5+ always had full bars in my house. However, the G5S+ has full bars sometimes, but gets only 1 bar a lot of the time. It fluctuates a lot. It seems to mostly become low signal when its asleep. They both will be using the same Sim card and network, but their amount of signal differ greatly. I also tested the signal with a Nexus 6P, Galaxy S4, iPhone 6S plus, Moto E2, and Moto E4. Each of them have full signal in my house all the time while the G5S+ gets 1 maybe 2. The wifi range also seems to be less compared to the G5+. I thought maybe I got a defective unit, but I got a replacement from Motorola and the replacement is exactly the same way. Is this just how the phone is? Did I possibly get a 2nd defective device? Or is it potentially a software problem and can be fixed with an update, if Motorola ever ever decides to? Not having signal when another phone will somewhere is a deal breaker for me. Can this be fixed, or should I just get a G5+? Thank you.

I'm afraid I've got the same problem with a straight talk verizon sim. I was running unofficial lineage 15 and now i'm running gzr validus (also oreo). In both cases I get either a very poor 1 bar of 4g, or 2 or 3 bars of 3g at home while my girlfriend is pumped all the way with lte on her verizon iphone. We have been in several other places where I complained about the signal and hers was fine. I switched to this phone because it can handle verizon (I WAS on virgin mobile/sprint with my moto G osprey getting FINE lte coverage but wanted to switch to verizon because their coverage is just a little better around here)! Well Now I'm On Verizon and guess what, my coverage sucks worse than ever. I actually hit 1x pretty frequently while driving around. It's pretty sad actually. I wish I could take the cameras and internal storage of this phone but have them back in my osprey. sanders looked great on paper but in practice has not been good to me.

Same with straight talk (which uses att). Same sim in my 6p in same location shows at least 3 bars. This drops to none sometimes, but everything still works fine, speed tests are the same regardless of bars. Even flashed a newer modem, no difference. Really wish the 6p wasn't about to die. But really, for $300,v this isn't a bad device, except for the camera. Hoping to see more development for this. I haven't but a rom in years, but was thinking about doing it again. Need more options!

It may not exactly answer your doubt but the network bars are not true indicator of the signal reception.
Check the network strength in Settings ->About Phone -> Status -> SIM status.
Less negative means more powerful signal. You can compare the signal receptions of the phones this way.

Hello and thank you for your reply. Here is a screenshot. It seems to have -84. The Moto G5+ would have the needle slightly better around -76 and the Wifi one completely to the right. It seems less strong than the G5+. Though what I mainly have been looking at the battery stats of G5S+ where it shows yellow being yellow for a long time or just alternating, while the G5+ would be green the entire time. It also seems to stay yellow when my screen is off for a while. Do you think this is a fixable through updates problem?

Mine is also unstable. It can goes from 4 bar to 0-2 bar in a blink. I checked with LTE discovery, it is even funnier, -89dbm 1 bar, -84dbm 3bar and it goes to 1 bar, then -88dbm 3 bar. I don't even know what the programmed range for each bar anymore.
It seems like this is quite common, even at Lenovo Moto forums, there are a lot of thread complaining about this problem.
Funny thing is the direct rival of this, the MiA1, also suffered this and partially fixed the problem with a patch last month so finger crossed that this is fixable by patching. Maybe you guys should also flood that forums as well or flood the moto email support.

I know that this thread is dated but I am VERY frustrated with the cell signal on my moto G+. I have had it since 11/17 and have been dealing with VERY POOR cell reception. We are in an area where there is little signal. We installed a cell booster and that gives a small signal on most phones, but my moto G+ is less likely to get or keep a signal. Hubby has Moto ext that is about 3 years old and he always has a better signal then me. I love the phone, but all the bells and whistles mean nothing if you cant gat a signal. Any ideas would be greatly appreciated

Really poor signal.
I also have this problem. Thought it was just me. I can't use it at all inside most buildings, and even outside my g5s+ often looses signal all together.

I have the same problem. I just moved to another city, inside my house (poor signal zone) i am having zero bars. I though it was the zone but a friend of mine has 3 bars, same operator but another phone.

Network problem
When I am install the stock ROM after using custom ROM my mobile network show emergency calls network are not present what I will do my phone is moto g5s plus Indian variant

have you solved? tips?
