No Signal - One (M7) Q&A, Help & Troubleshooting

So my htc one works perfectly well but i notice that when i'm in an area that has no signal and go back to an area where there is signal,i feel that it doesn't look for signal cause it still says "no signal". So what i do is turn airplane mode on then off for it to refresh the signal back.

That happened to me for the first two weeks or so that I had service with t-mobile, then it just went away... How long have you had yours?

Its the 3rd day that i've been using the phone now. Came from Taiwan.

Any have signal issues with this phone?

Its kind of hard to explain, I have reasonable signal at home but its like sometime it can't find my network at sits at no signal, if I manual scan it finds every network but my own, I have to restart the phone and all is fine again until I go into an area with no signal, the only way to get the signal back is a restart. Even when I do have signal however it can't be trusted either, late messages, missed calls etc, its almost like cell scanning or whatever just locks up
update ur baseband version to latest(i mean radio)

I had reception problems when I bought mine. They advised me to change my sim card since it was an old one.
Did that, reception got better.

[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

Signal problems

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.

Brand new T-Mobile Nexus 6 Lte not connecting

I have a brand new Nexus 6 64 Gb from T-mobile I just got. I had been on At&t with a different Nexus 6 so I know the phone inside and out. I was testing the phone and noticed the my wives new Lg g2 get perfect reception in my house. My Nexus get Zero bars Lte to 2. Mostly zero. Also I know when you make calls its over Hspa, but after I make a call it does not go back to Lte. Even if I browse the web or do speed test it stays on HSPA for 10+ mins or until I reboot the phone. It does this every time not just once in a while. Several times I have run speed test it has said no network even with 3 bars Lte. I did a lot of searching here and many people have issues with the Nexus 6 and T-mobile.
What do you guys think? Bad phone? T-mobile is sending out a new one just in case.
if you are using data, it wont swich back to lte until you have no data flowing. while you ate using data, it wont switch, period. and the bars dont really matter, as they don't really show your connection. some companies even add extra bars just so the connection looks better. if you want to see your real connection, open your main settings, go to about phone, status, sim status, signal strength.

I checked my wives phone. In the same spot I will have -115 and she will be at -102. Even right now I am at -91 and dont have full bars. Also after I hang up I can leave it there doing nothing but the screen on, it wont switch back to lte. Even doing Airplane mode on\off should kick lte back on and it does not.

airplane mode then back isnt supposed to kick it back to lte. for me it takes anywhere from seconds to 3-4 minutes. but that would also depend on the quality of lte signal in your area.

Z3+ Signals, No GSM, jumping 3g.

Hello.
I bought my phone just 3 days ago together with my gf.
She bought the exact same phone and same carrier as me on the same shop..
Around here we are supposed to have good 3g signals all over, but not inside our house, there we can only use GSM.
Her phone works perfectly, with 3-4 bars gsm signals inside house.
But i get nothing when entering house. NO bars what so ever, (even if i pick GSM ONLY from settings).
I got to service menu and read "0 db" on signal.
I tried everything, Clean sim, restart phone, factory settings, changing GSM/3g/4g priority etc, and even tried MY sim in HER phone.
Its defo a hardware/software issue on my phone.
My experiences from 3g and 4g with this phone is that 4g seem stable and good, while 3g (outside my house) seem to often go from max to none all the time. jumps up and down
and sometimes leave me with no signal for 5 minutes until they are back.
I contacted the carrier to check and everything seems fine over there.
Any suggestion? Could it be really possible that i got a faulty antenna? if im going with my phone to the store for a replace they would probably not belive me or take my reason for real
EDIT: Have to add that the past 12 hours of constant trying to figure out the problem i had a few cases with signals while i was trying to switch to "gsm only" but they lasted for 5 seconds and were gone again.
Had the same, send mine back, saw in the log of the repair department that you refreshed the software. But will check
if they have changed something. Comes back in a few days from now.
