[Q] HTC One signal drops

Hi all,
I have bought a Htc One M7 handset recently and I have noticed time to time there are No Signals (Limited Service) on it. When I switch off/ switch on or if I turn on the Airplane mode and turn off again, the signals will restore. This is happening around 2 times per day and really annoying. Need to know whether this is a known issue for the model.. I still didn't change the SIM and check. Please help!!!!!
Thanks alot!

I have the same thing
To add some detail for diagnostics see below:
- I travel into London every day and sometimes when signal drops in the tunnels it will never pick back up again after leaving them whereas my old One X did not have this on the same journeys.
- It even dropped out mid call and came up with the sim card icon at the notification bar as if no card inserted (but no selectable notification) first time its happened to this extent.
- Do you have a 4G SIM/connection or are you on 3G like myself? I'm thinking perhaps its something to do with trying to pick up 4G instead and completely disregarding the 3G connection that is available.
- I have also noticed that ever since getting the handset its never had as good signal as my One X which was pretty much always full signal in my normal areas (home, work etc) This may just be the way the handset gauges the signal not the signal itself but something to note anyway.

I'm having the same issue here in the US. It's prolly my only complaint with my phone.

I'm also having this issue but more sever with an all-day no signal. After reboot, I gain signal and I can't make and receive calls.

Try to turn 4G off.

How does one do that? Having the same problem, both wifi AND mobile network drop off. Wifi comes back on its own after a few seconds, the mobile data connection often comes back (obviously if not on wifi away from home), but the mobile network stays as no signal and doesn't come back, unless I reboot or cycle aeroplane mode. I know there's some problems with touching antenna, but this is happening a lot in the car, when the phone is powered and sitting in a cradle.

To turn off 4G you go to Settings -> Mobile data -> Network mode and then select "3G / 2G"
don't know if it'll help though, but trying is worthwhile

Thanks. The problems seems to have gone with that change. Perhaps it is some system thing kicking me off the network because I don't have 4G on my contract and my phone was trying to get it.
Now, if you can just tell me why my lovely 3-4 bar indoors signal on EE has dropped to 0-1 outdoors (as they deny there is a problem)

Are you sure it's not just cosmetic? Try going into Settings->About->Network and see if the signal (dBm) is dropping.

I have it constantly on att - I have to turn on airplane mode and turn it back off to get my network back, I have tried different roms and updates and still the issue is across all roms.

Maybe try this: in your dialer type *#*#4636#*#*. Once the menu is opened, select Phone information, then scroll down to Set preffered network type and choose one of the options (im from Serbia, europe, and I usualy go with GSM auto (PRL)).

Issue with 3g only
Whenever I keep it on 3G, it drops signals for 2 to 7 seconds at random intervals. People often complain that when they call, they get a message that my phone is switched off.. I am probably gonna try another ROM and SIM to see if that helps before dumping this phone forever.

how to solve limited service or loosing service on htc one m7
Hello
it seems to be a hardware fault where the radio is not staying on higher band
it seems to be having issues on 2100 and all umts and hspda or lte networks
however switching back to 2 g can resolve this issue and phone ( hope so) will never lose signals or drop then again
i tried this and for me this works fine so far over 12 hours now no issue
give it a try and see this should work
setting>data>network>2g only
by this you wont have option to use fast internet though but at least you can phone can be used for voice calls messaging etc and also wifi too
I was on stock lolli pop and tried to flash cm12.1 but does not help sort the limited service issue
enjoy and leave your feedback
Edit:
some people cant find 2g in settins>mobile network>preferred network type> lte or 3g only, the solution is go to *#*#4636#*#* phone info>set preferred network type>gsm only( this will put your device into 2g mode)
hope this work

[Q] LTE problems with DE on AT&T

I have a fully up-to-date Developer Edition, stock ROM, unlocked bootloader + root, with XPosed, on AT&T. I've had this problem a number of times over the past few weeks: LTE icon will be on as if it's connected, About Phone shows that mobile data is connected with a strong signal, but zero data up or down will transmit. If I go to the quick settings tiles, the 4G/LTE tile will be orange instead of blue or white. Apps that require a data connection will suddenly be unable to function. Every time this has happened, I've been in strong 4G/LTE areas and my wife's non-DE Moto X has had strong signal with no problems.
Rebooting doesn't work, toggling airplane mode doesn't work, rebooting to recovery + wiping cache doesn't work. The only thing that works (and it has worked every time) is to reboot to recovery and then wipe cache + Dalvik cache. Booting up after wiping, the orange 4G/LTE quick settings tile is back to white and all apps that require a data connection suddenly work again.
I don't know if it's important, but every time this has happened I've been in neighboring states, it has not happened yet in my home area. However, I've been in strong LTE areas when it's happened and the procedure above has always fixed it.
It's getting very frustrating, any ideas? Thanks in advance...

YOU apn settings file may be jacked. You can rest them to default. If you go to the mobile networks setting and under access point names. Just choose reset to default in the menu choice

Thanks for the suggestion - I'll try that next time this happens

Exclamation signal icon

T mobile

First of all sorry for my bad English. For those people on T-Mobile network after install elix r v2.0.1 ROM I lose my data connection. So I change the ROM to see if works but still no data working, so decided to restore ( nandroid twrp) and the same results.. So I went to cellular network, then APN and I change the T-Mobile GPRS on APn protocol to ipv4/ipv6 and I got data working.... I know some people already knows this. But people like me (noob) needs some help ..

Good news that it started working! Good follow up by the way. I was about to ask for more information in the OP but it's not needed in this case

I thought I was the only one. I just encounter this issue today

I deleted everything on my phone for nothing it was just the APN protocol.I really got pissed

On a side note does anyone know what the exclamation mark is for? I've seen it on both my WiFi and Mobile Data icons.

The exclamation on the signal bars means one of two things.
1. You are not getting a data connection. This may likely be because:
2. Cellular data is disabled.
I just called T-Mobile yesterday (well, two days ago now) to make an ass of myself because I had the exclamation on my signal bars and I wasn't getting data. Turns out I had somehow disabled my cell data. Pull down quicksettings shade, tap the mobile data icon, and check that the cellular data toggle is enabled.
However, I did run in to another issue a few nights before where data was enabled, but I really wasn't getting a data connection. My signal bars were full, and it showed HSPA, even though I usually have LTE in that area. I fixed it by attempting to select a different APN in the list. The APN I selected failed, it automatically went back to T-Mobile, and data came back after that.
Odd, indeed; hasn't happened since.

Ah ok. I only see it now and again to be fair.

4G not enabled when wi-fi is on

HI all,
On february 16 my provider network SFR (French in Paris) had some issues, I lost my gsm and 4G and since I can't turn on 4G and Wi-Fi on my HTC at the same time as I used to do before, now the 4G icon disappear when the Wi-Fi is turned on and I can read " Use my data plan when Wi-Fi isn't available" instead of "connected".
It seems that the 4G is in sleep mode, the icon comes again and data "connected" if I receive or send a MMS then disappear again.
If the wi-fi is turned off, I have the data "connected" with the 4G icon, as usual.
I have reset the SFR apn, still same, I have contacted their support, they say that it's normal for a smartphone to use Wi-Fi and not 4G all together, but I did when i wanted !
Now I can't, is any of u had this problem, know the cause and how to solve it?
Thank u in advance.

Do you have an option of automitically connect to 4G when wi-fi is poor turned on? It is in wi-fi's advanced options

Something strange happend to my P9 today

So today i turned my P9 (eva-l19) on, and i noticed something was off, first thing i notice is the sim signal indicators, now, even when connected to wifi they show 4G and 2G symbols, never happend before (attachment "0.png").
So, i start investigating in the mobile data menu to see if my phone is planning on using data on my second sim (which doesnt have a data plan), and luckily it didnt, but i notice that most of my settings (apn excluded) in that menu are changed, carrier aggregation was off, mobile data always on was turned on, instead of off, but the most strange thing is the default network type (basically there are a lot of options instead of 4G/3G/2G, 3G/2G, 2G). None of this options work btw. (i cant choose any actually, it just goes to automatic; only Global and below work).
(attachments "1.png", "2.png", "3.png", "4.png")
automatica means automatic
solo means only
globale means global
senza means without
preferita means preferred
Some other settings were modified, such as my battery indicator (it didnt have the % anymore), and my battery saving options (it was set to intelligent, instead of performance). Also my display time out was set to the default one.
For now i haven't found anything else and i really hope i wont.
This is really strange and annoying behaviour, as i didnt do anything that could have triggered such an event (no resets or anything), i really dont understand, i hope its the first and also last time it happens.
Anyone had the same thing happen?

Did you recently get a firmware update?

No, i didn't get any firmware updates, the last one i got was when i first turned on the phone, a month and a half ago :/
It's really strange behaviour, but i got an hypothesis going: i think the phone somehow acquires the location through the phone network, and displays the options related to that country, but in my case it failed, and glitched out. In fact, some of the extra network options that work are related to US networks (at least i think, EV-DO is a Verizon technology, which is US carrier if im not mistaken).

Same thing happened here!
It all started when i switched to 2nd SIM card for more data (both my SIMs has some limited ammount). I noticed, that Im running out off battery, so i switched battery saving mode from Performance to Intelligent. It didn't help much, my phone dies anyway. When booted, the story was same as yours...
Lots of various settings were changed:
-carrier aggregation was off
-battery indicator (% inside battery icon was gone)
-system sounds turned on (dialer, keypress, lock, and screenshot)
-all ringtones reseted to default
-all my defined alarms ringtones reseted
-display time out set to default
-default network type (basically there are world wide options instead of 4G/3G/2G ; 3G/2G ; 2G)
and the MOST ANNOYING: 4G/2G symbols in notification bar!
Conclusion:
It seems, that P9 modem/radio settings is somehow corrupted. Check attached screens..
Btw: noki57oo did you figure out, how to get rid of 4G, 2G symbols on your device?
Anyone else: Any idea, how to deal with this strange issue? Before I will do the Factory reset..

Same thing happened to me today. All I did, I have decided to restart my phone after few hundreds hours on stand-by.
All settings you've mentioned been set to default and more annoyingly, the icon of current network persists in status bar.
Only good thing is, I can now force the phone to use 4G only in network settings, haha.
