[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 !!!

poor signal htc any way of boosting it

i have had my phone a week or so now battery is getting better but the cell signal is really bad compared to my last device which was a n8 is there any solution or fix??

Ive a X on Orange and I have to say it seems to struggle to get a good Orange signal in areas I'm sure used to be very good on my sensation.

I am also with Orange. I am finding the connection very eratic. Quite often there seems to be none or one bar, then it will jump to 2 or 3, then drop to none again. Anyone else seeing this? I know there is a thread on the WiFI dropping at times.

plz report it to HTC. I'm on T-Mobile (UK) and having same problems. The more reports they get the more likely they'll take note.

Does the signal issue have to do with the way your holding the phone in low signal areas?

I'm on T-Mobile UK too which now uses Orange masts. Anytime it switches to an orange only signal I only get a G signal. I've turned off data roaming and all is well.

I've found similar issues but also I can't get it to report a signal better than -83dbm. Anyone else notice this?
I'm hoping the 1.28 update has a new radio.

Did you try another sim?
Also are you using a legit MicroSim or you cut your old sim into a MicroSim? This causes bad signal.

Try to avoid covering the lower left corner with your hand as it will greatly attenuate the signal. Not to the same extent as the iPhone 4 dramas, but still quite noticeable (2 bars).

Legit microsim direct from the network.

I can have my phone on the desk and I am actually seeing the wifi strength and the mobile signal fluctuate between 0 and 2 bars. It does that most times I take it out of sleep mode, it does this for about 60 seconds then stabilises. Happens almost every time.

Just chatted online to HTC and he was quite quick to say - faulty fone. ask for replacement.
But I have heard from a few people locally, all on orange, who have said they have had major reception probs on orange in last few days, dropped calls

update
Orange are blaming it on local cell issue, didn't listen when I said its not just local, but then again she did ask me to take battery out of One X !
Anyway, she got me to go to GSM only until local cell fixed. Am I correct in thinking that this will not use HSPDA now though ?

Do you mind me asking exactly what you asked htc? I'm finding that my desire is often ~10dbm better than my One X

Huw
Just told him I've noticed significent drop in signal from Sensation, lots more T-Mobile log ons too. He quite quickly said get fone swapped.
Orange reply as above, blaming local masts.
The signal seems to jump from one extreme to another either full bars or one bar only.

just to add on..
me in singapore here having this problem too...
and also using legit microSIM

im on vodafone and today noticed that in an area where reception is usually fine, i had nothing.
... anyone know if this could be solved by a radio update or is it perhaps an unfixable hardware problem?
got the flickering screen too... seriously thinking about ditching htc, but i hate touchwiz and not really sure what to go for... maybe just go backward to a sensation XE.

Installed the 1.28 update last night. Signal is now much much much better. I Don't experience any of the above anymore!

jaspabt , are you using a branded or unbranded HOX on orange ?

Signal problems & update?

Have been loving my One X for almost 2 weeks now but have a bit of a dilemma. Firstly does everyone have a similar signal problem as I'm getting i.e. once or twice a day I completely loose connection to my carrier (t-mobile UK) and sometimes have to reboot in order to regain network? Secondly if this isn't a mass problem do I return my handset or wait for the OTA update to see if this improves? I know there has been quite a bit of discussion on the effects of the bottom left corner giving the phone a so called "death grip" and was wondering if any update would improve this as this would surely be a hardware issue? Anyone's thoughts on this would be greatfully appreciated
TIA LEWY

Same.
I have the same issue (losing signal and having to reboot) around 4 or 5 times a day, on an unlocked One X on Three UK.
This only started happening to my phone after the 1.28 OTA update a couple of days ago. Before that, the signal was rock-solid.
Am going to try a complete reset of my phone and see what happens.

Some for me. H3g (tre) Italy.

My problems were from day one. So thought I would hold out and see if 1.28 made any difference. Since Wednesday after installing the update my signal greatly improved and have not had to reboot once! I cut down my existing sim and thought I may have damaged it, but it's fine now.

Same here (tmobile uk)

I'm on T-mobile UK and have a unlocked phone. Have the same problem although I have not had to reboot to get the signal back. Mine just seems to disappear for a few seconds and then comes back on it's own. I think it has improved slightly with the 1.28 ota. Signal does generally seem a little stronger now.

anyone out there had the update on t mobile UK .my signal is low ,its a bit embarrassing when my wifes galaxy ace on t mobile has got a better signal than my htc one.oh and the battery life is CRAP

Yes, I have. My phone is unbranded. Signal does seem better, gsm that is. Still get drop outs but not so often.

DID you buy it unbranded or did you do it yourself cheers

It was supplied unbranded.
Just noticed that I lose signal when it changes network. T-mobile to orange seems to be pretty smooth but when changing the other way the signal drops out for a while.

LT28i WiFi Reception is very low

Hi,
My Sony Xperia Lt28i international version gives trouble with wifi reception. The WiFi receiving strength is very less even if i stays near the router whereas my other HTC and Samsung does the job well. Is there any solution for this? Does any one face the same?

I have noticed the signal strength doesn't appear to be as good as some of my other devices but I have no fix.

I also noticed Ion doesn't have a good reception - both wireless & mobile. It seem to have some interference within the phone. I hope the custom rom will boost up the hardware.

I've noticed that the bars are lower compared to my old HTC Tilt2, both for wifi and phone signal, but I've never had problem talking on the phone or using the Internet even with only one bar. I don't think that there is a standard among companies about how to show the reception strength, so 4 bars with a Samsung probably isn't comparable with 4 bars on a Sony. So far the only place I´ve noticed a complete signal loss was a basement office where I've heard people say they also don't have phone signal.

I guess its because of the metal back cover.....

[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

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 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.

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

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

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.
