After Sending/ending SMS/Calls - Radio Signal lost for 1-2seconds

Hi,
I have a very strange and worrying effect on my new X1. I tried several 6.1er Roms (TouchIT) and also 6.5ROMS (now at gtrab BB 3.61) - also had different types of RADIO 1.14, 1.16 (the latest) - but always the same effect. Before I had a HTC Touch but no similar behaviour.
After sending an SMS or ending a call the Radio strength bar goes to "!" and no connection for about 1-2seconds. not always but often it happens like this. Even if it would just be something in displaying a good connection in a wrong way, WHY.
Does anyone else have this too?????
Thanks for feedback
Norbert

Can't believe that noone ever experienced something similar.
And to say this clear its not like this has some influence to my usage of the phone, but it is strange to see signal go and come back after seconds after sending SMS and after finishing calls, not always but from time to time.

I have the same issue on my Touch PRO, but I cant resolve problem.......
I try several ROM-s but its the same.
Phone calls is still works but SMS, MMS,.... in that moment isn't.

hey, I have the same problem as well
and I have no idea how to reslove it neither ...... hi5, or not? =.=

Hi,
I've had this strange problem since 1month back on my X1. The radio turns off after almost every phone call and sometimes never turns on again.
I have to soft reset phone to turn it on again sometimes.
Anyone that knows a solution to this problem?

Im getting really mad over this stupid problem.
Do any one have a solution? please share then..
Thanks for all tips!

yea i actually have this problem too!
i am on generic rom r3a with vodafone

yep me too ... but to be honest I ve kind of made my peace with the signal problems of this phone ... when I m on my desk in my study, the phone moves from four bars to no signal depending on where I put it on the desk (funnily there is no position on my desk that always gives me full signal - its always a different one) .. if I move the phone from say the full signal position to my ear I lose signal completely ... it d be funny if it wasnt annoying ... but I dont think there is anything u can do (besides moving to an area where u constantly have good signal)

This problem is so sick. Sometimes I have to soft reset phone after disconnecting phone calls. Is this hardware related? Maybe service centre can fix or replace the phone ?

shange, this sounds like a real problem. In my case the signal loss is also annoying, but after 5 seconds everything works normal again, so I never had to reset my phone after any call or sms finished. BTW I do not have stock firmware flashed -> SEX1 BB by gtrab.

Have you tried to use a different SIM card?

we are all on different networks and experiencing the same problem so i think it must be the phone
SONY ERICSSON Please address this problem

[Q] No Signal at all after replace the housing

After the replacing of my X1's housing with the new one in the SE Service center I went home gladly with my new X1 housing. I noticed there's an error in signal in my X1 when I was checking my phone at the SE center.. But I thought it was maybe due to poor reception thus I neglected it. (the officer in the SESC say so)
Now I know that there's some new problem arise.. Any idea what might cause this error? the phone can read the Sim card but there is no signal (no connection, no call or no data can be made). i try to check the antenna module, but it seem to be OK (i did not see any problem on it).
the next day i came to the SE center, they said it might be something wrong with the software (since i am used using cooked rom) how come it can make any different while i'm using it before i replace the housing. and they have to take it into the HQ. and guess what, it may take another 6-7 week... WTF
is there anyone having the same problem with me?

Well if you have the tools, you can try openingu p the bottom cover, that little rubber thing where it has the mini sony ericsson logo. Open that rubber up, and you should see a mini screw in the middle, open that up take it out, maybe just give it a quick clean, fit it back properly, and make sure everything is tight and see how that works out.
I've seen/heard a few people having such issue when taking the housing off, and not placing that radio/reception thingy back properly, therefore causing issues with reception.

I did it twice, just to make it sure that everything was on their place, also try to flash the ROM, The Radio but still remain the same....
any other suggestion or idea what should I do?

Same problem!
I had disassembled my phone by myself twice; the first time it worked perfectly, the second, unfortunately, it didn't!
I bought a new antenna module for U.S. $10, installed it myself (warranty ended three months ago), walked out of the service centre and voila; I had reception and managed to make a few calls. However, on the way back home, all calls placed while driving dropped every 5km, which means the hand-over between cell towers was failing. The moment I walked home it was dead; no reception whatsoever indoors.
Now the way I see it, this could be due to one of the following two reasons: either the RF power amp failed, which means that most probably the phone needs a new main board (too expensive, not worth it) or something went wrong during the assembly, like the smearing of a sensitive part by skin oil (thus causing a short circuit) or failure to position a connector or multiple ones to connect properly to their respective terminals/connection points.
Upon further investigation, I noticed that my phone wasn't properly grounded; whenever I connected it to a computer to sync using ActivSync or in disk drive mode, I got a small electrical shock (painful though) whenever I touched the phone. This, however, doesn't occur at all when I connect the phone to the wall charger. I disabled USB charging since day 1 of owning my X1i
I believe that the battery cover acts as a ground for the phone electronics; it touches four golden connectors which in turn touch the mini USB port, the GPS/Wi-Fi/Bluetooth antenna, a point on the main board half an inch away from where the loudspeaker is, and the metallic cover placed over the phone RF chips. Failure to ground the phone properly can result in either damaging any of these chips, building up a static charge that affects the antenna performance, or an open-circuit condition for one of the many systems on board.
Since my phone is fully working as a PPC now (PPC functions, Panels, Keyboard, Camera, GPS, Wi-Fi, Bluetooth, etc...) and since I get reception outdoors, and since I have a brand new antenna module, I am guessing that either the RF amplifier is dead, or the housing is ****ed up beyond repair (i.e. it can't be aligned perfectly to get perfect contact on all said points) that it's either shorting a connection, or opening one that is vital for the cellular radio to function properly.
So what to do? Well I forced my phone to do two things:
1. Settings > Phone > Band
- Network type: I chose GSM instead of Auto, as we don't have consumer CDMA in Egypt
- GSM/UMTS Band: I chose the correct band for my provider instead of Auto.
2. Settings > Connections > Advanced Network > Disabled HSDAP
What happened? It worked indoors for a minute, and then stopped working again! Frustrating! So what did I do? I ordered a completely new housing off CNN and will attempt to rebuild the damned thing.
I will update you if I find out anything or reach any results with this phone that I love so much and hate more than anything I have ever hated in my life...

More info!
- During the drive mentioned above, the phone was switching between H, E and G, which means that all three RF chips are, or all components of the whole RF chip if it's one responsible, are working. At one point I got 4 bars of H and call quality was perfect between hand-over failures.
- Before disassembling my phone for the second time, people were complaining about high-pitched static; it can blamed over the mic, the RF (antenna or chip) or humidity levels (which are currently as high as 85%) affecting cellular communication channels.
- Flashing the firmware (R3A Generic UK) and hard-reseting didn't solve the problem.

More Info!
- The battery cover isn't the phone's ground; it's grounded by being connected to four ground points: the mini USB port metallic frame, the GPS/Wi-Fi/Bluetooth antenna ground, a ground point on the main board and the metallic cover over the sensitive RF chips.
- This is definitely an assembly problem. The reception is great outdoors switching between all bands and speeds. On my drive to work today it worked getting G, E, 3G and H all in 4 bars. The signal, however, is completely unstable, jumping from one speed to another. I am more inclinded now to believe that a new housing will fix this problem. Your housing was probably handled poorly at the service centre, which in turn caused this problem.
My advice is to shake them a little bit and see what they will do.

A New Housing didn't fix it!
I purchased a new housing from CNN. It came in good condition. The phone looks brand new now but still no signal. I am sending it in for service. I guess I blew up my Power Amplifiers...
Good luck mate!

Same problem haa...
I still waiting for a good news from the service center... I have been waiting for a month..
I wish You a good luck too...

I'm having the same problem. I opened up my phone a few days ago to clean the keyboard. The bottom row wasn't working correctly. Unfortunately after I closed it up again, it wouldn't get any reception (and the keyboard's bottom row was still not working correctly).
So I figured it was the antenna and tried to reposition it. I even removed the rubber layer as described here: http://blog.whitesites.com/How-to-Increase-Reception-on-Sony-Xperia-X1__633958291637656250_blog.htm
Outside I get ok reception, but it's far from stable, inside I get none. And even if I get reception inside, once I pick up the phone, signal drops. So I thought about grounding as well, problem is I even tried rubber gloves and that doesn't solve the problem. I'm afraid replacing the antenna's won't help here and my xperia is dead. Anyone has any other ideas?

Been there too!
I tried the same solution the blog explained. However, I ended up not getting any signal at all. It's only after I purchased a new cellular antenna+buzzer module that the phone started getting an unstable signal outdoors.
Did you notice any small pieces falling off the main board or the housing? It's either a hardware failure or a simple short/open circuit situation that can be fixed in a blink of an eye!

Question
Is there any possible way, hardware or software, to test whether all chips on the main board function properly? I tried the diagnosis tool available here but it doesn't check the chips one by one.

Service Centre
I took my phone to the service centre 6 hours ago. With the new housing on, and new screws that I scored from a secret source of mine, they deemed the phone untouched and serviceable; i.e. it passed for a phone that hasn't been tampered with!
They told me to call back in four days. I will keep you guys updated. Cheers!

I wonder if that'll fix it So to summarize you have:
- new housing
- new screws
- new vibramotor
- new antenna
And those things twice and that fixed it maybe?
I guess it's time for a new phone for me

Vibramotor?
Who said anything about changing the vibration motor? I installed a new antenna + buzzer module; i.e. a new cellular antenna and a new loud speaker (external speaker). The loud speaker is housed within the antenna module. My bad, maybe that part was vague because I never explained it enough.
And yes, it has a brand new housing too. I only installed the lower part though, as the upper part is just fine. Maybe they will fix it man; maybe they won’t I really don't know. I do hope they will fix it though.
I am currently using a backup cheap Nokia and ordered the Sony Ericsson Aspen. If they ever fix my X1 then I can change seamlessly between both phones. If not, then I will just use my X1 as a media/GPS device in my car and an Internet device over Wi-Fi.

Lucky you..... if they can fix yours in a few day... since mine has been in the service centre more than a month, without any news...
they said to me that it will take about 6 week...

What a joke!
The phone remained at the service centre for a week. They called me yesterday, and told me that the phone was fixed and that the total cost was EGP 100 (~U.S. $18). I went over and as soon as I held the phone in my hand to test it, it lost the cellular signal. When placed on the counter, the phone had a constant E signal.
I asked to speak to the manager, who told me that they just reflashed the phone with the latest firmware (Generic UK R3A, which I already had installed). Oh, and before that, he said he was sorry but the phone had a hardware problem and that they don't fix hardware; they only flash firmwares and if that doesn't fix the phone, then the user is pretty much on his own! I refused to receive the phone, so he gave me a refund for my money and promised to have its hardware checked and get back to me in 24 hours!
What a joke, what an f'ing joke! I already regret ordering the Aspen that is due to arrive next week with a friend of mine returning from Paris...

OMG...
I do hope that you will get the good news next...

Bad News!
Deep breath... Ok!
Here is the deal: the service centre officially announced that the fault lies within the Mainboard; i.e. my guess that the Radio Frequency (RF) Power Amplifier Chip is toast was correct. They want to charge 90% of the phone's original retail price (which was EGP 4000 = U.S. $700) for a new Mainboard. I replied that that was impossible. They will contact SE's HQ and get back to me on Saturday to see if they can offer any other alternatives.
I guess that is the end of my ride with the X1. I will sorely miss it; it was a great phone while it lasted. Let's hope that the Aspen won't die on me in a year as well...

terrible signal and spotty data

im sure this has been asked before but couldnt really find any good info. ive had my hd7 for almost 3 weeks. so far my data has been very spotty. like one minute ill load a page in IE or sync email and itll work and the next minute i cant load web pages or anything. and then the next minute i can. sometimes i cant for several hours and sometimes i dont have a problem at all. all this happening with 4-5 bars of 3g consistently.
also in my 4th floor dorm i get 1-2 bars of gprs AT BEST! its terrible. and i have a huge window but still cant seem to get good service.
one more issue is when people call me, sometimes it goes through. though with the ring delay. and sometimes it doesnt. and they call over and over and my phone never rings. not cool.
anyone have any advice? thanks

It could be a hardware problem of the antenna get a friend with the same phone and test if the same happens to him if not get a replacement...

+1. Something wrong with the handset, I reckon.

i had the same issue with my first handset. i got a new one less than a week ago and its the same issue. i could try a third cuz i believe it will be 14 days on thursday. i was told once i got 30 days. but was also told i got 14 so idk. but i may try another handset but im thinking its just the ****ty placement of my room in this building. as soon as i step outside its full 3g

Had mine replaced because of the same problem, not much signal where i would usually get signal on same network in a different phone.
Sent it back and recieved my new phone within 3 days of sending my phone off (Royal Mail Special Delivery (insured) @£5.50) although it is a freepost address.
14 days to return phone no questions asked.
30 days warranty (phone is faulty)
I use my wifi more which seems to be okay, seems okay with hspda signal browsing the net and marketplace etc.
The 30 days will be from your replacement phone, not from the date of the original

[Q] How did I kill my WiFi reception?

Hello all,
My Nexus One has been through some serious physical abuse. It's gone flying out of cars because I left it in my lap and decided I was out of car. It's been dropped from arm's height, much to a mall phone salesman's dismay, to convey a sense of satisfaction with my mobile device. And it's been dropped from about a foot's height on carpet, which cracked the digitizer.
Got that taken care of relatively easily, and changed the housing while I was at it. Now I have abysmal WiFi performance. Where is the WiFi radio/antenna in here? It looks like the top black plastic cover houses the GPS and BT antennas {both of which still work perfectly}, and the bottom plastic cover houses the WCDMA/GSM radios, which also still work perfectly. Where's the WiFi antenna? How can I check if I nicked it or something?

Anyone? 10char

I don't know for sure (never really bothered to try and figure it out the few times I have had my phone apart), but I think it is the little wire on the side opposite of the volume keys that can be seen when you pull off that initial black plastic piece under the battery.

This wire is connecting the WiFi antenna indeed. I'm not sure where the antenna is, but I think that baseband antenna is the big one on the digitizer, and the lower cover is the WiFi antenna.

Ever have any luck with it? My wife and I both have T-Mobile Nexus Ones. They are both running CM7.1 with avjomomma's T-Mobile WiFi calling. We have poor cell service in our house, so we rely on WiFi calling.
My phone has great WiFi coverage. My wife's phone receives so little that the T-Mobile app senses poor signal and drops back to the cell network. If I hold our phones side-by-side, she always has 2 bars less than I do. I even tried moving my AP to the middle of the house, but even that wasn't enough.
She's getting increasingly frustrated, and so am I. I should also note that we paid only $120 for it, and it's a little beat up. I think it's possible that the WiFi antenna may be disconnected. Before I tear into it, do you guys think this might be an accurate assessment?
I also need to perform a backup and start over with a fresh CM7.1 and WiFi calling reflash.

I am running into the same problems as sheik124,
I broke my digitalizer and replaced it myself, everything ran perfectly for 1 month but dust was coming inside the screen, I reopened it to seal better for the dust and since then my wifi signal is useless, I have wifi only when I am 2 meters from my router and with very low power.
I suspected about the coaxial cable but I know it is not, I reopened it and checked its continuity and conection, the cable is in good condition and correctly attached in both sides, I cleaned as much as possible inside the phone but it did not improve...
Anyone knows where are located the wifi antenas?

To remove dust from the screen I suggest you use compressed air (very expensive), or adhesive tape (not Scotch clerical) clothing for something like this, well, damp room to do it.
And I would like to see photos of the device, without them it is guessing on coffee grounds

Multiple Turbo's, Multiple Problems

Let me start off by saying that I really like this phone and I'm no where near giving up on it.
With that said, I bought 3 of these within the first couple of days after release.
For me - Current occupation - IT System Administrator with 18 years of experience in various areas of IT
My son - Current in college, going for his Computer Science degree.
My daughter - Currently in college and surrounded by tech her whole life as I am a tech lover.
I mention who we are only so people don't assume that we are typical end users that can't figure out the difference between their heads and their asses.
My son has returned his Turbo twice (both metallic black). The first time, he had major scrolling issues. Phone would "fling" through pages unprompted while touching the screen. The second one he returned because there is a glue problem or something like it with the back of the phone, near the bottom. Makes a creaking noise (loud) if you press on the back near the bottom.
My daughter has just returned her first (32 GB Ballistic). Hers will not connect to WiFi without a reboot. Very annoying. Airplane mode first then trying didn't work.
Mine - I have not returned by 64 GB Ballistic yet but I think I am going to exchange it. I have problems with WiFi connecting also. It isn't as bad as hers in that mine occasionally connects without a reboot. In addition, mine definitely has some sort of touch screen issue. The screen becomes unresponsive at times and requires me to press the home button to "reset" the screen. I installed display tester and checked the multi-touch test and found that sometimes it won't register all fingers or one fingers touch is chaotic, wiggling all around while the others are ok. I also have a volume issue of some kind. I have to turn the phone up past half volume just to hear it... even in a quiet room.
I do really like this phone and have every intention of keeping it assuming that I can get one that doesn't have issues. Not sure if it was rushed or whatever but there is a definitely some build quality issues going on here.... Makes me very sad.

This is an issue for some and I believe there are some youtube videos demonstrating it.

For the call volume issue try disabling the equalizer, I read on here from a few people that that is the fix, I use the equalizer but haven't had a problem with the sound.

Thanks guys. I'm surprised that there haven't been more comments. I was kind of hoping that people would say, "no problems here" or "yeah dude, wtf". Still love this phone. I think its the motorola apps and how they have nailed it in the "what I personally like" categories. Active screen and such are great.

I'm one of the few who got a good Turbo. Bought it on launch day and have had none of the problems people on here have mentioned. No creaking on the back, no scroll issue, no screen temperature issue, nothing. The connectivity issues you talk about don't happen to me. I'd say just keep getting them exchanged until you have a good one.

OMG FINALLY someone with my same problems! So I'm not going crazy. I swapped it out once, had same issue with the new one, but now it seems the issue is only at my works wifi. I have seen online there are issues with the phone and Cisco routers, and I assume we have Cisco routers here at work since our phones are Cisco...so I'm just chalking it up to an issue with my works wifi and letting it go. But what happens for me is I'll connect to wifi and then it'll disconnect randomly, so I have to either turn airplane mode on and off and fiddle with that and "forgetting" the network, or just restart my phone. It's rather annoying, but I have no other option as the phone works wonderfully on all other wifi networks.

Never knew I had the same glue/creaking problem until I read this. Now it will bug me until I do something about it. ?. What's the solution? Exchange or diy repair?

What's the verdict on the crackling noise underneath the ballistic nylon? Did they exchange it?

Only problem I have is the call volume could be a little louder. Coming from a S4 I usually had to turn it down.

I'm really wondering if you guys that are having trouble with call volume are not holding the speaker in the right position. I never had a problem with my call volume until today. My third call of the day seemed to be extremely quiet until I repositioned the phone and got the speaker lined up more with my ear. For comparison sake, I had to do the same on my S3 on almost every call, so I wouldn't consider this phone bad on that account either. It's something easy to try anyways before exchanging a potentially otherwise good/perfect phone. If it doesn't work you wasted 10 seconds.

Yeah, they exchanged it. No real problems with Verizon in that regard.

I dont think its just Cisco though I did read some other articles about that and the type of wifi encryption. This has been at a few different locations. For my daughter, it happens at our home but my son doesn't have any issue.
