Searching... / No Signal

Is there any difference between the "Searching ..." and the "No Signal [!]" ?
When on the train in tunnels the device rightly goes to "Searching ..." while you'd expect there to be no signal, then when I hear other people on their phone, mine's displaying [!] with "No Signal" Why? Is there anything that I can do to make the device connect faster?
I've set the device from Auto to GSM in the Settings > Phone > Band, which has helped a bit...
Is there anything else?
Regards.

Theoretically, there is a slight difference since "Searching" means that the PPC is actively searching for a signal and "No signal" simply means that the PPC is traveling through an area where there is no tower for it to connect to. It depends on how well your provider has covered that problematic area. As far as I know, there is no direct way to influence the search speed for a network. This is possible on handsets from Motorola for example.

Don't think there is any way of getting better reception unless you get yourself an external antenna. The signal strength depends on a few matters. First it is the service provider (e.g the phone company). The guy with the phone ringing might have a provider whom coincidently has a signal tower much nearer to the tunnel compare to yours.
2nd, there is a matter of phone. Each phone receptions are different. Not just PPC based. Some said that the Sony's older model has very bad reception and some said Nokia / Motorolla has very good receptions. It depends on model and company I guess. There isn't really much you can do about it.

I think a lot of it has to do with your device trying to save power.
I work in an office where I have no reception, so basically all day my phone says "no service" however there is full reception right outside my building.
When i leave the building, i dont automatically get reception and sometimes it can take 5 or so minutes to get it.
I think the phone must go into some sort of battery save mode whereby after a certain time of having no reception, it increases the time between checks for reception.
This i find is very very annoying and most times i have to turn flight mode on and off.
This problem was even worse when I had the xda II.
Do any of you find you have this problem too?

Strange GPS behaviour on Virgin SGS2 rooted to Rogers

Here's what happens... if I have just GPS enabled (no Wi-Fi), and I tell it to locate my position while I'm at home, it tells me I'm about 5-10 kilometers away. It's in the correct town, but isn't near where I actually am, and I'm standing right in the open, no buildings or anything.
Now, if I enable GPS and Wi-Fi, it tells me I'm currently where I USED to live, which is about 50km away from my real position. The place it tells me I am is actually right near my gym and where I used to live, but I haven't lived there for close to two years but I still frequent the gym.
Anyway, I'm totally confused. I could understand that if I enabled my Wi-Fi and it's telling me that I'm near where I used to live, it could have something to do with having the name of my wireless router cached at that location, even though it hasn't actually existed at that location for two years. What leads me to believe that this is some sort of caching issue is that if I am at work and use the GPS (or anywhere else I don't frequent for that matter) it locates me fine, instantly.
So... what can I do?

Anybody have any idea? This is awfully frustrating...

You could try using GPS status from the market to reset and download your AGPS data?

That fails i would backup data and factory reset as symptoms are of faulty settings . You could also replace the modem .

I'm also having issues, "GPS Status" app sees 10 satellites but never locks. This is outdoors.
With your Wifi location issue, I think that's because the google vehicles collecting street view data recorded your wifi SSID to be at your old house, which is why it thinks you're there.
EDIT: I should also mention, mine worked fine before rooting, then I used Chainfire's kernel to root and I have the issues that we're seeing (JP_XSG_KG2 and ZS_OZS_KG2).

One of the reasons I'm waiting on a proper Canadian Kernel to use.... too many unknowns.

Fixed!
Using a different kernel and ROM (XXKG6, Android 2.3.4):

GPS locks within about 5 seconds outside and network speeds seem to be the normal for Rogers.

Do you have a working 3G connection?

So, I downloaded that GPS app and did everything that it had available... nothing really helped. When I'm anywhere but my house, the GPS locks fairly fast, but can still be somewhat slow.
I believe I was having no issues as well before rooting, and I used CF Root as well. I obviously agree regarding updated firmware from Samsung/Virgin... I'm sure it could very well resolve this and some other issues.
I have a 3G connection... it's always listed as H+ though.

Yep! It indicates 3G when idle, and when I'm using the data connection it switches to H+. Rogers download speeds of ~4Mbps.

Nexus 4: radios behaving badly

The one thing that's keeping me from fully enjoying my new Nexus 4---hassles with radios, both wifi & cellular.
1) On my home wifi network on all devices except the Nexus 4 I see solid, constant download speeds of 25Mbps. My Nexus 4 consistently only gives me 4-6Mbps. If I disconnect/reconnect sometimes I can see speeds slightly higher than that, but only temporarily. This isn't generally a huge deal because 4-6Mbps is fast enough for most things on a phone, it just bugs me that every other device in the house gets 25Mbps.
2) Of bigger annoyance is my cellular data connection, it drops off multiple times per day. The cellular signal strength indicates full bars, along with the 'H' icon indicating I'm connected to T-Mobiles HSPA+ network. Voice still works fine but the data connection is dead--nothing will connect--Speedtest, maps, Google Search, Facebook, etc. This forces me to either turn on/off Airplane mode or reboot the phone completely to regain my cellular data connection. On my previous SGS2 I never experienced this issue. It drives me nuts to not be able to pull up a phone number, directions etc at the times I need it most.
Does anybody have any similar experiences or suggestions on how to remedy these issues?
Edit---FYI I'm fully stock but rooted. 4.2.1 update not yet applied.

1) Check APN settings and make sure your account is properly provisioned by calling T-Mo CSRs. I had a similar issue with my Nexus One back in the day that was fixed with a reboot after they reprovisioned my account.
2) Flash factory image, in case it was a bad flash of the radio. It happens.
3) If 1 & 2 fails, or you don't want to try #2, call the Nexus hotline and get yourself a replacement.

Called TMobile and had them reset my account, I'll keep an eye on it the next couple of days.
Right now I'm downloading a cached Google map via WiFi and it is slooooow.

I also notice on edge the signal is inconsistent.

Hi
The Wi-Fi issue is something happening to others, seems to be a driver bug.

Wifi connectivity is my biggest gripe. I'll step 6 feet away from my router and I lose a bar. A couple rooms away I fluctuate between 1 and 0 bars.

Did you ever find a cure for this? I am having the exact same issues on my O2UK Nexus 4, anytime I want to use the data connection its almost guaranteed not to work and involve reboots, Airplane mode on and off etc

Im having the same issues. My data just drops wifi and cellular. I dont get full signal wifi or cellular. I live in india and flashed the latest .54 which was released in india recently. I managed to at least get cellular data going but my strength still low and data drops still on both wifi and cellular. Its super frustrating. Any ideas?

try reflashing the OS on your phone and try changing the wifi channel on your router.
changing the channel on my wireless router really helped signal to all of my devices. there may be lots of interference on the channel you're on.

I may reflash OS but i just got the phone today so ill slow down a bit. I flashed the radio one would think that would be enough? Anyway I have many other devices on my wifi without an issue and i used wifi analyser and theres no overlap with other routers and i experience this on 2g 3g and wifi so it looks like some modem problem. Unfortunately the phone was bought 3 months ago in the States and im here in india so im kind of stuck

There are known issues with the Nexus 4 wifi speeds slowing for no apparent reason. Also, known issues with the LOS (loss of signal). You can find information and bug reports on both of these issues.

I dad see some threads reporting this issue. Unfortunately i dont see any solutions or resolved threads. Additionally people either have it they dont as i see it i cant see people witching sides. Its just a little frustrating. Any opinions on whether kernel swapping will help?

Did a full flash from scratch. No progress. Also i went to my friends place and signal was perfect for like 4 hrs straight but every other place ive been since has seen choppy signal.

Pretty bad. I ran a test a few weeks ago and I can go up to 450 feet from my router (old Linksys) without a problem, and after that it gets iffy, and finally disconnects at 500 feet. I am seeing an average of 20 Mbps on wifi. Now if I can only get my cellular connection (non-wifi) to go faster than 1 Mpbs max I would have a usable phone.

I have a slightly diff issue.
If I reboot my phone, I connect to my router no problem. If I turn wifi off (to save battery) and then turn it back on.... it shows my AP's as out of range.... but I do see my neighbours AP's. I also have an N10 with has no issues at all with wifi (and none of my other divises have issues either).
When I bought the N4 they seemed to be having an issue with it when setting it up.... but I was not paying close attention. I am wondering if I have a bad phone on top of the "normal" wifi issues that other are experiencing.
Think I will revert back to stock and swap it for another phone to see if I can at least just turn off / on the wifi rather then reboot to connect (how sad is that?)

**** UPDATE ****
I picked up a cheap belkin router and set it to AP mode.
My N4 has no issues at all with it. Connects when I want it to right away and is fast / solid connection.

GPS and cellular being killed off together

Anyone else seen this behavior?
This has happened twice to me now... These are the symptoms:
1. Very poor signal area, phone going in and out of coverage (in someone's house for several hours)
2. Using WiFi, also going in and out of coverage (may not be relevant)
3. Return to good 4G coverage
4. 4G seems to work fine
5. After typically 10 mins or so travelling (or after some event?) the cellular & GPS connections drop completely.
6. Reboot required, then all works fine again
I'm on EE network in the UK
I have noticed all this through my navigation app (TomTom). At step 5 above the status bar still shows the 'GPS active' icon on the top right list of icons and no bars (neither 4G/3G nor 2G) signal strength under these circumstances.
So something is killing off BOTH GPS and cellular radios? Apps (even broken ones) can't do this, can they? So this will be a bug in the OS, right?
Stock/unrooted LPD23.118-10

I know this is an old post but it is still relevant to any X play users.
Has anyone found a fix for this.
My X play will run for weeks using GPS and various mapping apps without problem and then it will say looking for a GPS fix and the Cell signal has also gone even though I know that a very good signal is available (my work phone is with me on the same network).
The quick fix is to go into the drop down menu on the home screen and turn the location icon OFF then ON, the phone then gets a fix within a seconds (even when travelling) and then in 10 to 20 seconds the 4G icon comes up, first with ! then once it has made a proper connection (IP address I assume) it goes away and all is well.
I guess that the radio driver for the GPS and Cellular side must be interconnected someway or there is a memory issue which is cleared by turning location OFF the ON.
Any thoughts folks ??
The X play is running standard MOTO 6.0.1 android.
Thanks

Severe WiFi issues Please help!

Hey guys, on my ZTE Axon 7 A2017G, I'm having really bad WiFi issues.
I've attached some screenshots, but overall it seems like the WiFi keeps dropping out randomly.
My WiFi is not at fault here, I have a 30 Mbps connection and it has full range where I'm sitting, (5-10 metres from router) and there is no interference.
I do believe this to be a faulty phone, but if anyone has any suggestions please do help. I do still have this covered under warranty, so I can return the phone if needed to.
:good: :crying:
edit:
also for some extra information, the two arrows next to the WiFi icon are not always present whilst using the phone on WiFi, and when they are not present, the phone's apps will say no WiFi and if I check the settings app, it says under my network's name: Connected, no WiFi whilst there is full connection and I would have to forget my network and reconnect again.

I have an A2017U and it also has unreliable radios. My WiFi stats show the AP being weak and about 50m away. It suddenly dies and comes back saying it's a strong signal 4m away. Run a WiFi analyzer on the Axon 7 and another phone at the same time. The Axon 7 will show APs randomly fading out while the other phone shows steady signals. I recommend returning it under warranty. You might get another phone that dies less often and ZTE will lose a bit of money for not maintaining their flagship product.

Alright, thanks I will try the WiFi analyzer and return the phone under warranty.

So, I tried the WiFi analyzer with my zte axon 7 and a family member's galaxy s8 and both phones show around the same signals for the various APs and both phones randomly phase out APs at around the same time (probably due to weak connection, because its the neighbours WiFi) and so I'm really confused to what the problem is. @kevinmcmurtrie

My Axon 7 has the radios just drop dead. One common cause is that it wants to switch from 2.4 GHz to 5GHz shortly after waking up. It can roam fine but band switching kills the connection for about 10 seconds. Other drops are a total mystery. A WiFi analyzer shows APs randomly vanishing or muting for a while then coming back, with no relationship at all to real signal strength. Same goes for the cell radio. It loves dropping to a legacy EDGE tower when there's plenty of strong LTE signals around. Putting the phone in my pocket kills the cell data and it never comes back until I cycle airplane mode.
I've seen this on three Axon 7 phones. I have two and one was replaced, for a total of three. The second phone became stable when LineageOS was put on it - no drops, no vanishing APs, no EDGE, no missing cell data. I'd use only LineageOS if WiFi Calling was supported.
