[Q] * HELP! * One X Keeps losing Signal

Hi guys,
After weeks of waiting, i finally got my HTC One x today.
But there is a problem.
When i put my Sim Card in , I get around 2 Bars of signal, and then it goes away and the cross comes over the bars, then the phone says ' Preparing Sim ... ' , then the 2bars appear again, then they go away and the the phone says ' Preparing Sim ... ' , and on and on and on and on again!
I am extremely sad and dissapointed. was really looking forward to this phone.
Can anyone help with this issue?
P.s. the phone is stock and untouched.

even i am having the signal problem when compared to my other phones. Nexus sits on full signal and One X keeps moving between 1 bar and 5 bars when holding in hand..have checked the display phone in my local shop which is also behaving same....do all of you have this problem?

I had problems with a cut mini-sim. Got it replaced with a proper micro sim and all is fine.
M.

For the people who have cut there SIM card, make shure you are using the new generation SIM card. Cutting a old generation one can bring issues!

That's weird. My one x is getting signal where my sensation had none!

Woke up today, no signal and sim couldn't be found.
Was fine last night.
Either T-Mobile deactivated it because they have sent me a new micro sim, the phone is a dud or somehow the cut sim decided to break itself over night somehow.
If the new sim doesn't fix the problem, the phone is going back and ill just buy something crappy to tie me over till GS III.

It has good wifi reception, I'm getting signal in places where I'd have to wave my hands around in the air before. But the gsm signal is really annoying me
Sent from my HTC One X using XDA

none of you have my problem . My is faulty. no reception at all.

Mine jumps from H 3 bars to G (gsm), back and forth. Very sketchy signal.
Using a new micro sim I received today.

Hmm.. I'm using a cutted SIM and it didn't show any problem. Instead, I am getting signal at dead spots compared to my DHD in the past. Weird..

Got a microSIM sent out by my provider. Works fine. I'm getting even better 3G reception than with my Desire S. Sounds like a faulty sim to me.

Strange behaviour you guys are having there. My signal strength on the same telco has been improving switching fr DHD to HOX. Some places with weak signal reception those day in DHD (with 1 or 2 bars) now I could get 3 bars.
Most of the users in my region do not faced such issue, we are seen the coverage is jumping fr H to 3G back and forth rapidly, which we believe is due to service upgrade (cos have been notice such behaviour even in DHD)

I have exactly the same issue with you.
Actually this is my 2nd OneX, the previous one has "yellowish display", but there was no signal reception problem.
After replacement, I found the new one has the same problem described by you. It changes between 3G<->H quite oftern, and I found that mobile radio goes off very often, but then it's showing me "preparing SIM..." and signal comes back again!! Since my SIM on the previous OneX has no issue (at least I used it for 4 days already without this problem), so I don't believe my SIM is the root cause (and mine was the official micro SIM from telecom).

Yes, I agree that for some location that normal phone doesn't have any reception signal, OneX does have signal. And it also changes from 3G<->H quite frequently.

I'm having this issue too. It seems when the phone is trying to talk on 3G instead of H, it doesn't work. So, everytime the signal switches to 3G, I lose data. I still haven't been able to run a successful Speedtest.NET test on the phone.
Anyone have any ideas?

Also gave my HTC One back to supplier. Signal issue became so bad that i had almost no signal.
I found that when i was in a building my signal disappeared. Hold your device upside down and you get better reception. Also made a benchmark test when I got the phone and it score 4700+
when the signal issue started i did a test again and it only scored +/- 3700. Must be hardware. I tried Hard resets and nothing....
Going to be a long wait as I'm in Namibia in Africa and phone was ordered in UK. But overall just an awesome phone !!!

Low signal on hox

Today I noticed that the signal on my hox is worse than on my old desire. On places where my desire got constand hsdpa the hox switches constantly from hsdpa to 3g with less signal bars. Anyone else with this problem ?
Sent from my HTC One X using XDA

Same here, I now have to go outside my office to be able to make calls that dont drop. With my SG2 would get full bar in my office, but with HOX only get 2bars

Yup mine seems the same, stumbled upon this thread looking for a solution so hopefully someone who has some success resolving the issue will be able to help.

I'm having this issue too, hopefully when s off has been achieved we will be able to flash different radios it has fixed this issue on all of my previous phones.

My phone also seems to have a somewhat weaker 3G reception than my SGS-2, although they both act in the same way in regards to switching between 3G and H+ all the time. I think this can be corrected partly via software updates since the wifi reception is much stronger on the HOX than any unit I ever had before. It is the same "antenna" the receives both signals isnt it?

Mine seems to get faster 3G speeds than my Gnex and GS2 (unless my network has improved in the past 2 week)
But phone signal is far worse, especially since the 1.28 update... I'm not getting signal now in places where I used to always get signal
Sent from my HTC One X using Tapatalk 2

My data speeds have dramatically decreased after the latest 1.28 update - quite dissapointing! I have no use for better signal if the data is worse lol

Have been lurking on here for a while now and noticed a few threads and comments about reception on the One X
I am in the same boat, was using a Desire S and now a One x and noticed there is a distinct difference in signal level between the two. Not just the signal bars (desire s has 4, One x has 5) but the dBm levels too.
I would say that 80% of those that have had the update and posted about signal have said that it has improved, regardless of carrier they use.
I went into the store where I bought mine from (ThreeUk Retail shop) and they were going to swap it out there and then for me but the handset on display (working demo) had a similar level to mine, so seemed pointless as Im guessing that all/most of the units are like this, it isnt an isolated case.
So, im not sure what to do now. I have just swapped my main number to Three (and its now my only number). Im without coverage far more than I used to be with Voda, or with Three using the Desire S.
Three shop says they have a 28 day policy for faulty handsets, I hope that the update is out before that so I can see for myself.
Brilliant handset though…. screen is lush, using the phone is a pleasure…. just brilliant.
Steve

I am noticing far worse signal on my handset than previous handsets , an awful lot of the time my handset switches between t-mobile and orange , whereas previous handsets were solid t-mobile all day , and also the data speeds are worse. I am not very impressed as the 1.28 update appears to have made this worse, and its an unlocked generic variant in the uk if thats of any help
cheers
james

My signal is loads better.
Before the update I couldn't sit on the sofa and make a call I would get 3bars then nothing.
Now I'm a fairly constant 4 bars sat on the sofa.
I'm on Tesco (so O2) I was going to take the handset back before the update.
Battery seems twice as good on a completely different note.

I have had a similar experience as descb600f. Prior to 1.28 my signal would drop regularly. After 1.28 I am finding it is far better, regularly seeing 3 bars, where before it would continually switch between 0 and 2 bars.
WiFi reception is great, puts my Desire to shame!

So which is it, does 1.28 make signal alot better or not? And what about actual call quality, its one thing getting 3 bars but another if calls are choppy

I do have to agree with the signal/Wifi issues on this device.. I came from a Nexus S (GSM model) and I used to get good HSPA/UMTS signals on that device, I also have a Wifi network setup in my house, it covers most of the house and some of the backyard.. However when out in the backyard the One X seems to drop the connection to the Wifi network, however my old Nexus S still has atleast 2-3 bars of Wifi connectivity and constantly keeps the signal/connection.
Has anyone else had issues like this with Home Wifi networks not getting as great a signal as other devices?
If I hold the One X in one hand and the Nexus S in the other and move away from the Wifi Access Point, the One X drops signal strength a lot quicker and the Nexus S keeps connection/signal a lot further away..
Bit dissapointed with that, and hope it's some how able to be fixed with software/firmware upgrades in the future?
Also I noticed the One X seems to switch between H/3G (HSPA/UMTS etc) quite a lot more than the Nexus S does, same network, holding both in same spot..
Apart from these minor issues and the screen flickering issue I'm more than happy with the One X..

WiFi and 2G/3G are two different chipsets and different antennas.
I have also notices dropsin the last 3 days, including hours with no reception at all
Need to switch from 1.26 to 1.28 soon to try it...

I should say I live in an area with only 2G reception and we sit in a dip partially hidden from the transmitters.
We can only get O2/Voda (orange/TMob if I just want to live upstairs in a corner of the house) and since the update I now have no issues with reception just like I used to.
1.28 has resolved my issues.
On the wifi front
I live in an old stone cottage with timber frame extension (wifi b/g can't make it thru our internal walls in the old part of the house), I have the N wifi router upstairs in the extension and have no issues with losing WiFi either (didn't have issues before 1.28).
Hope this helps people, I realise some may say it has got worse but for me the difference is night and day making the phone completely fine.

I just found an old 3 SIM (from a dongle) and popped it into my desire s and placed both by the window running Network Signal App for 30 minutes.
Both were attached to the same tower and the HOX was getting between -89 and -91 dbm, the Desire a consistent -75dbm.
Just hope that Three shake their touche's and get the update approved ASAP…. im quite a technical guy, but the idea of rooting and doing the update myself gives me the shakes…..

Loss of signal, no auto reconnect.

I am having an issue on my One X (unbranded and unlocked) with the signal vanishing and not reconnecting unless I force it. I was wondering whether it effects all networks or just networks that use more than one carrier. Three has its own 3G network but it uses Orange 2G signal. I also saw a thread with the same issue on T-Mobile / Orange which is also dual carrier.
I am wondering whether it is the switch between these networks which is causing it to lose signal and not reconnect.
I have had several instances where my signal has an R next to it as if it is roaming, this would be when it is connected to the Orange 2G network, I never had this problem on my Desire HD or Sensation.
Does anyone know of any issues on Vodafone or O2 regarding signal loss or is it just networks which use multiple carriers.
My One X is stock and bootloader has not been unlocked.
Thoughts?

Are you still on the 126 SW?
As your unbranded then you should be able to get the 128 update.
With 126, my Three handset recieve level was about -88 to 91dbm.
With 128 its now at -75dbm in the same location.
Most, if not all of the roam to Orange has now been disabled, remaining where there is no Three signal at all.
Steve

No I have upgraded to 1.28, unfortunately I am still in an area where it does switch to Orange 2G signal.
It seems to hang on to 3G until I have virtually no signal, then goes to no signal and doesn't reconnect unless I force it. It seems to mostly happen when I put the phone away on my pocket so I dont notice I have no signal until I check my phone.
I lost signal today and to test the reconnect I left the screen on and I drove about 20 miles through large-ish towns and it didn't reconnect once, had to force it when I got home.
Not sure if this effects single carrier networks, O2 or Vodafone?
Sent from my HTC One X using Tapatalk 2

Have you had the same issue with any other handset?
Are you a new customer to Three and this is the first you have seen of this?
Reason I ask is when I was thinking of going to Three for my main phone, I tested with a handset I just used for tethering off the one plan.
I drove out of town to an area where I guessed there would be no Three coverage.
The signal hung on for ages but when it dropped I made a note of where it dropped. After a few moments the handset went over to Orange 2g. I then drove back home. I must of drove at least 5 miles past the point I noted earlier before the Orange signal itself dropped and had to force the handset to Three myself.
This sounds similar to your issue and was with a Desire S….but you say you didnt have this with previous handsets. All very strange
Steve

I've had a Desire HD and a Sensation both on Three and never had issue on either of these.
There must be something different about the way the One X handles the switch of signal, or maybe it's just faulty.
Might try some other SIM's from other networks, if that doesn't work I'll get a replacement.

I'm on three and it never seems to switch to gsm just looses signal all together and takes ages to reconnect once I move location. this is a proper pain I've had the phone replaced three times changed sim still not got better I'm thinking its the radio version on this phone or some software related issue.

If you're phone is from Three you won't get the update until Three release it.
I did see on another thread that Three won't be releasing 1.28 as HTC are currently working on the next update. Don't know how true that is.
My phone is unbranded and unlocked to any network, which is why I got the update.
Think I'm going to get a replacement and see if that's any better, hope it's not a general issue with the one X having lower signal.

If you dial *#*#4636#*#* on your phone and select phone info you can select GSM only which is 2G, this really improves signal but because it's 2G you are stuck on really slow data speeds.
If that is the case and you've had 3 replacements, maybe it's worth holding out for the next update to see if that fixes the problem.
I'm a little uneasy about returning it for a replacement as I don't have any other problems with it (bad screen seal, banding on display or yellow display) I may end up with more problems with a replacement.

Is any chance change three rom on factory rom?

I had similar issues to what you are describing with yours on my original unlocked/unbranded HOX on T-Mobile. I had issues on top of the ones you mentioned where it was also saying I had a signal and had appeared to lock up and would just drop the mobile network and say at the bottomg of the screen "preparing sim".
Most the time I was stuck with putting it in and out of airplane mode to make calls, only for them to drop or fail all together.
This was on both 1.26 and 1.28 FW. In the end I took mine back and swapped it and the replacement has been perfect since. so it was without doubt a hardware fault in my case!
Good luck solving your problem, but I would suggest taking it back and getting a straight swap.

You can't change you ROM unless you unlock the Bootloader at HTCDev and this will void your warranty with HTC.
Three will release an update eventually, and 1.28 is no better signal wise for me than 1.26 was!!

Interesting, I too had the Preparing Sim message until I got a new SIM from Three, this seemed to fix this message but I am still having Signal Problems.
I think I'll follow your lead and go for a replacement, I have to use Airplane mode to force the signal to reconnect as well.
Thanks

I can confirm I have these problems. I'm on three but the phone was from Dialaphone and with orange but is unlocked. I have exactly the same problems as those been described. This is a very irritating problem that makes me miss calls and texts in my poor 3 signal area.

I have the same issue on my device. On my 2nd replacement and its still the same.
No problems with my iPhone 4S.
Hopefully a radio update will sort this out.

I think it might depend on location, in some areas the 2G signal (Three use Orange network for 2G) has been turned off. In my Area (South West England) I still have access to the 2G GSM Signal.
Obviously Three save a lot of money from turning off GSM and not paying Orange to use their network.

Intermittent phone signal

I've had my HOX now for just over a month and i'm loving it. One thing that is slightly bugging me is that occasionally the phone signal will completely cut out giving me an 'x' where the signal strength normally is and telling me that I can only make emergency calls only.
This will correct itself within 30 seconds or so and go back to giving me a signal. This doesnt happen all the time which has made it harder for me to diagnose. Do you think it is a problem with the sim card (Orange UK network) or is it likey to be an issue with the radio software?
I never had an issue with Orange on my Desire although this is a different SIM card.
Any help or advice would be appreciated.
Thanks

I think this is a common problem I'm on Vodafone and this happens to me. I applied a fix when installing insertcoin Rom a while back and it doesn't do it as often now.

I'm glad this has been mentioned now because my One X (On Vodafone) drops connection all the time. The amount of times that I have been somewhere and needed to transfer money through the Natwest App and haven't been able to is getting annoying now. As I am not rooted I can't try any fixes but I have found by using GSM only around where I live, it won't drop signal half as much or often. I don't have a 3G mast near me so its always dropping connection switching between the two as opposed to a smooth transition.

Hi,
You are not alone. I'm on Orange UK and have seen this problem on quite a few occasions. Unfortunately, as yet I can't see any pattern to understand when it happens or what causes it.
Tim

Happens to me on 3. Sometimes I have to hard reset to get it back.

Glad that its not just me. At least I can rule out an issue with the sim.
As it seems to cover more than 1 network, could it be a radio issue that is addressed in a future firmware upgrade?

It is definitely not just you. I'm in Malaysia on the Maxis network and have this problem as well. It happens randomly - at the most it happens twice in a day.
Do you also sometimes get the message 'Preparing SIM card...' at the bottom of the screen?
I brought my phone to the HTC service centre and they offered to take it in to test the radio. I will do this when I get back from my holiday and keep you guys posted!

I do get that message at the bottom of the screen. I'd be interested to hear what the outcome is once you've had your radio tested.

Yep, it's the [email protected] radio firmware HTC has provided us with. Radio 2.05 is much better. HTC are useless with updates. I've had problems with my network connection for 2 months!

Me too.
Except I am on Tim @ Brasil.

This is nearly always down to signal.
If you're in an area that has decent 2G signal but fluctuating/low 3G signal then the phone will keep trying to connect to the 3G signal. Sometimes it'll be too weak and not be ableto connect and will stick with the 2G signal. If the 3G signal is only just strong enough to connect the phone will switch to 3G mode (dropping the 2G signal). Then it'll realise that the 3G signal is too weak to do anything with (showing an 'X' in the signal area) and drop back to your full 2G signal.
3G signal is breathable which means that if lots of people are connected to the 3G mast then it's signal area (i.e. distance from mast) is reduced. If no-one is using the 3G mast then it's area is bigger.
Perhaps your signal is breathing in and out of use where you are.
Obviously the radio can have an affect too, but with so many people using the same radio software there are going to be some it works well for and others it doesn't.
Personally, I keep my phone on 2G/GSM Only for most of the time and then switch to 3G when I want to use data. I hardly ever get problems with signal, and if I do I shrug and put it down to the coverage in the area I'm in.
P.S. Saying this, my 2G signal seems to drop in and out when I have WiFi turned on. Usually when I'm using wifi I'm not making calls anyway so it doesn't bother me...

Thanks for this useful info. How do I set my phone to 2g only so I can test this theory out ?

It seemed 'good enough' to me, but I only had 2 days with my phone on 2.05 and then my camera wouldn't work at all. So I sent the phone back for a replacement. Crazy it's still not fixed!
I've had 5 faulty phones now.

3G signal is breathable which means that if lots of people are connected to the 3G mast then it's signal area (i.e. distance from mast) is reduced. If no-one is using the 3G mast then it's area is bigger.
Perhaps your signal is breathing in and out of use where you are.
Obviously the radio can have an affect too, but with so many people using the same radio software there are going to be some it works well for and others it doesn't.
Personally, I keep my phone on 2G/GSM Only for most of the time and then switch to 3G when I want to use data. I hardly ever get problems with signal, and if I do I shrug and put it down to the coverage in the area I'm in.
P.S. Saying this, my 2G signal seems to drop in and out when I have WiFi turned on. Usually when I'm using wifi I'm not making calls anyway so it doesn't bother me...

Which is correct, however any phone working correctly should manage to switch between 2G/3G without problems, i.e. you should not find the phone without a signal at all provided there is 2G coverage, which seems to be the case being reported here. My previous phones with 3G/2G never had a problem, and the HTC One X has been no different for me, it hasn't dropped it's signal, I'm on Vodafone in UK.

Thanks for this useful info. How do I set my phone to 2g only so I can test this theory out ?

Settings -> Mobile Network -> Network mode then set to GSM only.

This is happening fairly regularly for me on UK T-Mobile. Seems to happen when switching between Orange and T-Mobile or T-Mobile and 3G T-Mobile. I've got a ROM that distinguishes between a 2G and 3G connection in the carrier name area.

I think this is a common problem I'm on Vodafone and this happens to me. I applied a fix when installing insertcoin Rom a while back and it doesn't do it as often now.

Which, and what about it was supposed to be a fix? I'm using MaXimus 2.1.

It happens to me also. I'm on 3 in Denmark. They providing only 3G coverage in area. So far, I figured out that it's happening when I'm loosing signal completly (i.e. when I go down in concrete basement), and when I'm within coverage again, phone is unable to register on any network at all. Sometimes can help turn airplane mode on and off, or sometimes I have to turn phone off and on again.

[Q] Signal issues UK

Hi. I am on three network UK and since I had the m8 from new, have had intermittent signal issues. One minute I will have 5 bars then it will drop to one bar while I am still in the same place. This is my second brand new m8 now with the same problem as the first. I also have a moto g on three to compare it to, and the reception on the moto g is far more stable. I can't find any posts from the UK of anyone with the same problem. Anyone else having signal strength problems? It affects signal as a whole as in both calls and data.

Im with 3 and have intermittent signal issues but thats nothing to do with the phone or network provider in my honest opinion.
Are you running a custom rom? Might be a radio issue?

Thanks for reply. I am still on stock at the moment because I didn't want to have to un-root and return to s-on etc. While I wasn't sure what the problem is. If you don't think it has anything to do with the phone or the network provider, what do you think it is? As I say, my moto g signal is far better and stronger. I don't get signal on the m8 where I normally have done on all my previous android phones. Thanks for any more input.

I'm on 3 and also have ****ty signal strength, yet I'm able to make and receive calls without issues.
Tbh I think it's an issue with three.
I was with Vodafone back in the day, and use to have full bars yet intermittently I was unable to make/receive calls.
3 appear to have some Gremlins, but after using almost every other provider, oddly they're consistent.

Thanks for reply. Tbh, I have been trying to not take too much notice of what the signal strength bars are telling me and just trying to use it anyway. But it just seems strange to me that I have only just started seeing this happening since I got the m8. As you say, three have been consistent, and for me, they have been consistently good. I now find the m8 not having data connection and no bars where before, other handsets are fine. Oh well. Thanks for your reply.

Hi. I have sent mine in for "repair" now, but am not holding out much hope that it will be working any better when it gets returned from HTC. I am in Hereford, west midlands.

Got the same, now on a second device thanks to the local thieves;anyway both handset's had the signal bar observation you made in the post.
So I'm guessing it's 3's network.
I'm in South east London.
Data & voice are a bit hit & miss
Cheers

Thanks for reply. I think what i'll do when I get my device back, is to try a few other networks sim cards and see what happens. Perhaps I should have tried that a bit sooner but as I never had trouble before, it didn't really occur to me that it could be the network not playing nice with the phone. Thanks for all the replies guys.

I've been noticing signal problems too with three. I'm in Northern Ireland. I tweeted them and they said they were aware of a mast issue near where I live.

I tried EE, Vodafone and three and all had the same problem, left it on top of the desk and watched as the bars randomly switched from 3 to 1 and to none, got my device back so will test and see if it's better

I had been with 3 UK for about 5 years and a couple of years ago I had a Desire HD and I was experiencing the same exact issues except sometimes the signal would get lost completely and even airplane mode or phone reboot would not register with the network again but since then they have improved the network (a little), I can tell you there is nothing wrong with your phone or the radio. 3 have great deals but their coverage is very patchy I am now with o2 UK and have not had any problems with reception or dropouts. one more thing; a bad simcard can cause reception issues so you might want to try another sim from 3 to see if that helps at all.

Ok. Cheers for the info. I have always found three to be fairly consistent in a good way in my area and surrounding. I have ordered two new sim cards since my original and still have the same issues. Cheers.

I have exactly the same issue however it doesn't seem to effect the usabilty of the phone. I had a Note 3 before which also suffered the same issue so I would assume it is Three.
I think Three are in the midst of a big 4G switch on and from what one of my pals in the store said they are doing a hell of a lot of work on the masts at the moment. I do however have a more consistent signal with the M8 with regards to signal stability (not the bars)
You may want to look at getting an app which measures the actual -db rather than bars. It may be that you are swapping between a couple of masts.
Have a look at Opensignal or this one https://play.google.com/store/apps/details?id=com.signalmonitoring.gsmsignalmonitoring

Nice one. Thanks for the information. I will have a look at that app when I get back. Cheers.

Seems like the repair done the job, signal seems stable now

Was with Three when I had my Note 3, always 2 bars but calls and texts went through fine. Decided to dump them and head back to O2 and five full bars and full signal wherever I go. Three = Not that great IMO

Thanks for letting me know. I'm glad your device is working better after the repair. That gives me hope for my device now. Cheers.

I have been trying not to take too much notice of the bars and just use it anyway but it still doesn't seem to be working as well in certain places, as my other handsets have previously on three. Oh well. I just took out another 2 year contract with three. I'll see how the network performs over this time and make a decision when the time comes.
