Hey guys, my OnePlus 3t is losing signal reception for couple of seconds throughout the day. First the Internet cuts off ("4G" mark disappears from the status bar) then all signal bars are goneand after a second or two it comes back just fine. Did anything like this happenes to you?
The same SIM card works fine in Samsung phone in the same spots.
I sent my phone for repair, it came back with replaced PCB but the issue is still there.

Hi,
Did you ever find a solution to your problem? I'm having the same issue. Random complete drops of signal for a few seconds.
I'm also having issues with the radio in the phone. This last week I purchased a different phone to see if the issue was my cell connection. The replacement phone worked much better and faster on a LTE connection in the same locations. My issue is same as OP but I also lose LTE+ frequently and the speed and throughput drop to <1mb/s. Love this phone but getting frustrated with it. I'm running stock OOS, unlocked bootloader with root.
I have also same problem and I tried
this
1. Open dialer
2. type *#*#4636#*#*
3. Select phone information
4. Select "LTE only" from
"set preferred Network type"
5. Back
6. Done
Now I don't have this problem
Signal an Internet running great.
Maybe it's caused by inability to talk correctly with closest mobile station, does this happen everywhere you are or just at a certain place or country? Same with different operator/SIM-card? I'm not having these problems here in Sweden using Vimla/Telenor as operator (unless I of course step into a bunker ?)

I'm in Romania and using Telekom as operator. I've checked that the LTE bands that the operator uses are supported by the phone. I would get the signal drops even when having full reception. For now I've tried setting LTE only as suggested above, and am currently waiting to see if the issue persists.
I was able to resolve this matter. It was down to incorrect network settings (APN and such). It turned out my mobile operator didn't have the right defaults for OnePlus. I called them, entered manually the settings they gave me and the disconnects stopped.

Are you guys having this issue on OOS or on LOS Roms? Any Los ROM I try, my signal bar seems to fluctuate. Doesn't seem to cause a drop in data, but it does drive me insane

That's normal and caused both by external factors like the cell towers and their power management, and also by the phones chipset/radio power management. Having maximum signal strength at all time would cause extreme battery drainage on the phone.

Yes, but it's not normal for on Los my signal to disappear. On OOS, my signal bar is always solid white, on LOS I can have LTE, and then the signal bar will grey out. Pretty sure it's ROM related since it only happens on LOS

Then it's probably a bug in some subroutine, yes. Not much we can do about it, other than hope someone discovers the fault in the source code, probably somewhere in the RIL integration code.

This is not about poor signal, it's about losing signal completely, like going from full to none instantly, and the inability to access the internet or make a call for a few seconds.
You're right, that sounds more like the RIL crashing and restoring itself.
I've tried all tips and tricks mentioned in this thread but the problem persists. I'll send the phone for repairs.
I had the same - going from full bars to grey and back in 20 seconds. None of the repairs worked, it was down to network settings causing some recycle process every 2 hours or so.

For anybody still having such problems, I got my issue fixed in the end also. It was a network-related but not caused by wrong APN settings. I filed a complaint to my operator and after whatever magic they did there, I didn't encounter this issue anymore.

I've had this on all CM/LOS roms on all my OnePlus phones and Samsung phones. I've been complaining about it for such a long time but no one cares or blames the carrier.
I just stick to the original os now as I cannot rely on my phone if it constantly drops signal.
I think it has to do with the way LOS interprets the signal detail from the chip vs OOS.

Same here. Also happened on my G3, but ironically didn't have this issue on the Nexus series..

I already posted about this problem but then I thought it was due to sleep mode.
So I still have signal problems with my One.
I saw that I had only one or two bars for the signal where I had a lot better reception with other phones.
I already put my sim card into a Galaxy S3 and a Galaxy Y, both of them have a far better reception than the One (4 to 5 bars).
My phone was already sent back for repair three times, they already swapped my motherboard two times, but it does not help.
The last time I got a bit angry in the shop so they took my phone in to test it out.
After four days they said they had no signal problems.
Last resort, another swap of the sim card card but now the signal is even worse.
I did notice when rebooting the phone it starts of with five bars and after two minutes or so it goes down to one or two.
When making a call with one bar it goes up when calling to four or five, some time after the call it goes down to one or two.
I already installed signal Guard Pro to check for effective signal loss and I had quite a lot durng the day as during the night.
I got the name of the customer service manager for the Benelux and France (Aernout Arends) but I do not have any contact information of this man apart from his linkedin.
So I sent him a Linked In invitation. If he responds I can ask him about this phenomenon.
Before the One I had a Sensation XE which I was very pleased with, since running on the One this problems started after a couple of months and since then it keeps on going.
I'd like to solve this since it was an expensive phone, apart from the signal loss I'm still very pleased with it but in the end a phone is used for calling and with a bad signal this is compromised.
I hope anyone out there can help me (or somebody at HTC), if not I need to buy another phone and I think I cannot sell this one since it isn't working properly.

is it switching networks (3g/4g LTE)? voice can't use LTE 4g, so it will drop back to 3g for calls and then go back to LTE 4g once the call is done.
signal bars are a really poor way to understand your signal strength. there are some apps that help (network signal info for example) which show your strength in a more efficient manner, as well as what network type you're connected to.

I turned 3G/4D off, I only turn it on when necessary, so that won't be the cause.
I installed network signal info right now and when I have one bar signal, this app gives me -102 db to -105db and it's over haf of its bars here, this info seems to look like mi signal is a lot better than the one bar I got.

you can set a value in your build prop that is specific to signal 'adjustments' from your particular provider. might then give you more realistic values along the lines of the Network Signal Info app.
I'm sorry I can't direct you to the link as I don't have it bookmarked.

Every day when I am actively using my phone, once or twice I'll notice that the HSPA or LTE icon will disappear for a few seconds, I'll lose my data connection, and a few seconds later the HSPA or LTE icon will come back and I'll have data again. Signal bars do not change, only the data icon disappears.
Happens a few times pretty much every day, and I usually have good signal strength (full bars) when it happens, so signal strength is not the issue.
I'm on the .93 firmware on AT&T in the U.S.
Anybody else seeing this behavior?

I don't necessarily think it's a network issue for everybody. I've switched my SIM between my Z3C and my iPhone a couple of times and I've never had the problem on iPhone, or on any other Android phone I've used in the past for that matter...

I get this on talk mobile (virtual vodafone) - I've only noticed it at work and it's very repeatable every 10 minutes or so it drops 3g for a couple of seconds - I notice it because it then triggers my VPN to re-initiate. It's a carry over Sim (cut down) from the Galay s2 I was using previously.
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?

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.

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.

[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.

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.
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....

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.
