[Q] Cubot X9 3g connection issues - Miscellaneous Android Development

Good afternoon all,
I recently got a Cubot X9, and honestly have not been too impressed thus far. The screen came with buggy as I'd have phantom keys. That has died down a bit, but as it turns out, this phone will NOT connect 3G onto my MetroPCS network. I have tried everything, including activating it at a Dealer.
Has anyone encountered this issue and is there a work around? I understand the phone is not 4G capable, but I would assume if it is advertised as 3G that it would do so.
Thanks in advanced!

Have to say is a pretty good phone for the money once I got my screens set up how I like them and never had any issue with 3G connections. My only gripe is the woeful GPS performance has you bouncing from street to street if driving and running you cannot go in a straight line at all.
If the GPS could be fixed easily stacks up there (apart from benchmarks) with most phones out today

Fed up with 3G/HSPDA Issues!

I have been having some really annoying issues with the 3G capabilities of the Touch Cruise. I actually think it is something AT&T is doing on the network, but can't be sure. Anyone experience anything like this? Here are the symptoms:
1. The TC worked great on the 3G network when I first received it. Averaged around 700k speeds.
2. I flew across the state and the phone was unable to make or receive calls. I noticed the 3G/H symbol just fine, but no voice, no data. On a whim, I turned off the 3G and went back to Edge and everything worked fine, slower - but fine. I noticed this behavior on several subsequent trips. Coverage maps show 3G capability.
3. I've been to numerous other cities and experience varying 3G speeds, but the phone definitely works.
4. Lately I've noticed the phone almost seems to experience 3G "fatigue" by the end of the work day. In my home area where it seems to work fine, I'll look at my phone and it will either have no service, or it will not be working on 3G (no calls or e-mail). By later in the evening, it appears to be back to normal.
5. A reset will normally bring things back at least temporarily.
6. I have been trying out new ROM's and Radios posted here, but don't think they are the source of the issues. I've upgraded and downgraded with the same results.
Is this the AT&T network? Could it be with the proliferation of 3G devices, the network becomes saturated particularly by the end of the day?
More importantly, if 3G is for some reason unavailable the phone should degrade gracefully enough to allow it to continue to operate on the Edge network without any interaction by the end user.
Anybody else experiencing this behavior? Any tips? Any resolutions?
Re:
You could try to fix the GSM and 3g bands in the phone settings from automatic to your specific band. Normally that reduces ur battery usage and provides better network clarity. It might just help.
Secondly you could try the SEA 6.1 official rom as that seems to be one of the best ones so far.
I had plenty of 3G / Edge issues when i first received my TC. I spent many hours with AT&T tech support as well as a few conferrence calls with AT&T and HTC. No one was able to come up with a viable solution. Being a geek at heart I spent many hours testing roms and radios. Only a few combinations work with the AT&T edge network. My ROM is based on 18129.0.4.5 with a murata radio 1.58.21.23(must be certified murata) and has worked for me with no problems.
Hope this helps

cell signal issues with vzn tp2

Is anyone having cell signal issues? I moved from a moto q9 napoleon and never had any signal issues; i.e.alway getting evdo signal while in my home, but now with the tp2, i spend most of my time with a 1x signal. And this (1x signal) negatively impacts my battery life.
The better question - is there a fix or solution?
Thanks
John
I have noticed the same thing with my phone. Only had it for 2 days. It gets 3G until I turn into my drive and then it goes to 1x. I had a Treo 700WX on Alltel and always got EVDO. Verizon and Alltel are sharing the same tower. The TP2 has been getting 3G at a lot of other locations that I have tried. I did notice that I was getting no signal lines at home, but when I made a call, it went to 2 lines. I wonder if it is a power saving thing, but I guess the 1x isn't helping the power.
Terrible problems with 1st TP2
The first one Verizon sent me had terrible problems with the radio. Iffy to connect to a call and even though it said 3G could hardly ever connect to broadband. Kept getting irritating popup telling me it could not connect to #777. The replacement they sent is working great here in Ft Wayne. I will update when I get back out on the road and see how it does roaming. I suspect a few may have just been defective since everything about this new unit is better.
As a side note, if anyone knows which registry key can get rid of those stupid popups, I would be grateful since I can't seem to find directions anywhere. I really don't need constant reminders after I hit dismiss the 1st time.
i've been having horrible battery life as well - and received the #777 problem as well yesterday. i thought it was a network issue or some software that caused the problem. i guess it isn't, though it seems to be working fine now? anybody else see this error?
i'm coming from AT&T so it's hard to get worse reception than that.. will see if it is as good as my last verizon phone however.

[Q] Nexus S extremely poor wifi

Hello there,
i know that this topic has been already debated several times but I couldn't find any solution to it.
I'm running MIUI 1.8.19, android version 2.3.5, kernel version 2.6.35.7-g3cc95e3, baseband I9023XXKB3.
Wifi signal is extremely weak, few meters away from any router and the connection becomes extremely unstable making the wifi experience a total nightmare.
I've been previously tried NSCollab and also different baseband configuration files but nothing seems to get things better.
For what is worth (even though the wifi is bad anywhere and with any router) my router is a Linksys WRT150N running on DD-WRT.
The Nexus S wifi thing seems to be a little bit controversial. Some users seem having no problem with it, some other experience the same problems i do.
Question #1: is that a hardware, software or both kind of problem?
question #2 : is there any workaround that would allow me at least to comfortably browse the internet from my bedroom (5-6 mts away from my router) without getting disconnected every other 30 sec?
Thank you in advance,
D.
You kept a phone that can't hold a wifi connection over a distance of 5m? I'd have returned it on day 1.
It's normal that the distance of WIFI on smartphones is less than say a laptop or pc, but 5m is definitly not normal.
Verify w/ other wifi networks, same problem = return it. If not, bad luck, might be the combination of your phone + the router not working properly.
You can try changing radios to see of that improves your situation, for some it did.
Yes, it is normal having a weaker wi-fi but my blackberry has no problem at all. it is the nexus and it seems to be quite a widespread problem around the globe.
Well i was abroad on business and couldnt return it. Just looking for clues....
I know that netarchy's kernel uses updated wifi drivers, you can try flashing that and see if it does anything.

Hi there,
i tried several kernels: netarchy, matrix and also installed MIUI and also tried the MIUI Brainmaster ROM. Same result: in my bedroom the wifi signal score a miserable -85/90 db. Is there any kernel out there optimized for wifi? I mean, it seems that the wifi weakness on the nexus S is a common problem.
Thank you in advance.
It sounds as though you have a hardware problem or a router problem. I have to go to a room in the other side of my house to get -90 db and even then it doesn't disconnect. I have to get about 200 feet away before it disconnects.

Also it might have something to do with interference on whatever channel you are connecting on but I don't really know enough about wireless networking to help you troubleshoot that.

What i'm wondering is wheter Samsung uses different wifi chipset on the same phone cause i'm not the only one complaining about it. just google "nexus s weak wifi" and you'll see hundreds of people with the same problem.
still wondering if there's a software solution to it.

It has been documented that the Nexus S uses an under powered wifi chip. The chip uses less power but with that comes a weaker signal.
mine seems to be weaker than average...
Yours does seem weaker than normal, but no nexus s has decent wifi range.
What I have done is purchase 2 old linksys wrt54gl routers, have them both loaded up with DD-WRT and then link them (bridged mode or WDS if you prefer) and situate the routers in either end of my house. I have a decent sized 3 bed detached house, with a 70ft garden, I can now get a reliable wifi connection near the end of my garden on my nexus, where as previously I couldnt get to the back door
Might be an old thread, but I just traded my trusty HD2 for a Nexus S and god I hate the WIFI reception on this thing.
I am on stock 2.3.4 Rooted with KD1 radio and 2.6.35.14(Pete's) kernel. Tried just about anything out there, and nothing worked out.
Being a Pure Google experience phone, I was expecting a lot more happening for this phone, but it seems that my 2009 released HD2 was way better for all it had to offer.
Subscribing to this thread!
WIFI is fine for me, same as with HTC Desire, and stronger than iPhone 3G...
Its terrible on my Sprint Nexus.
Where I have an Ipod touch and a LG Optimus, they get an 'excellent' connection anywhere in the house. The Nexus drops the connection all the time, shows a 'poor' 5Mbps connection.
Will swapping the phone do any good?
OK.
I bought my Nexus S yesterday and I was soooo disappointed because of its poor wifi reception... But...
I am a network Administrator and a few minutes ago i just couldn't beleive that about 10 meters away from our Cisco Antennas i had about 89db signal so i started playing... and guess what i now have 55dbs at the same spot! What i found out is that Nexus S doesn't work well with High Frequencies so I disabled channels 8-13 and my AP had to work on the low channels and BAM! everything works fine now (My phone is in stock FW)
I hope I helped

Awesome tip! Thank you so much
I found this channel number which it uses to make no difference to the wifi performance.
I tried channels 1,6,11, no difference.
The phone just has poor wifi.
As a note, usually I don't use the low channel '1', as this gets interference from microwaves more than the upper channels.
just bought a Nexus and and experiencing heavy wifi issues.
I tried changing AP channel but doesn't fix.
Testing signal strenght with a LG Optimus one for comparison:
1- LG: -72db. stable
2- Nexus S: -85db web pages loading fails quite often.
Tomorrow my NS will return to the store. Bye Bye

Radio Performance

I am curious as to how the phones signal has been for those that own it. I currently have the S3 and have had it since launch but don't like how it gets stuck in 3g or 1x when losing 4g temporarily even though I know i'm back into a good 4g area. Overall signal is good but the transfer between 1x/3g back to 4g is terrible and my next phone i'm hoping to avoid all the frustration.
I have thought of buying the moto x just because its motorola and they're known for good radios. I have some time and am thinking of waiting until the moto x2 or g3 but its one of those things where why wait if it's good.
Thanks in advance.

To be honest with you. Samsung has the worst radios. I had an s3 and it dropped signal too many times. I then got the HTC DNA and it was so much better. I believe HTC has a way better radio than Samsung.
My All New One
I was kind of concerned about this too before I bought mine. I come from a long list of Moto phones. The only non Moto phone I've had was a Rezound. I had it for all of one day. The darn thing would only ring probably 1 out of 4 calls I received. 1 out of 3 if I was lucky. I took it back the day after I bought it and they looked at it and told me there was nothing wrong with it. Well, I've never had a problem like that in my house with any Moto phone. So, I told them to keep it and went home with a Razr Maxx. You can see why I was concerned.
Anyway, I have to say, this phone has the best radio or at least the best reception of any phone I've owned. I work in an area that is quite iffy as far as a signal goes and my Moto phones would hold a pretty good signal there but depending on where I was at any given time, I would lose the signal and have to walk around a bit to get it back. In the shop there, forget it. I pretty much had nothing. The signal on this phone shows it's slightly weaker at work than my Maxx but it's worked flawlessly for me out there. I can even take it in the shop and it works great. Signal is weak but somehow it seems to hang onto it. Listened to Tune In Radio for 5 hours in there today and never lost the signal once.
I also went to a town today where it's worse than at work. My Moto phones there would work but constantly on and off. I was listening to Tune In there today too and it did have one hiccup for 10 seconds or so but that was it in a half hour's time. But, that doesn't surprise me in that location. What does surprise me is that it only stopped once. No way any of my Moto phones would do that well there. Anyway, maybe I'm just lucky but I'm extremely pleased with mine and don't regret buying it at all.
The old faithful LTE ON/OFF FOR thunderbolt app still works like a charm to control the radio bands on an HTC phone.
Highly recommend to install to force lte or 3g when needed.
The S3 in particular had a wretched radio, I couldn't get signal for the life of me in my house. Verizon ended up replacing it for me with a Note 2 which was better in many regards. The radio so far on the M8 has blown the note 2 out of the water, it doesn't even compare. I get a steady 10-20 asu improvement over what I used to get with the note 2 in most situations.
Liking what I've read so far.
Been so so for me. I've always had ATT and personally only had bad reception in my home. Almost anywhere else I had 4g LTE everywhere. Never saw Edge connection, worst was 3G.
I just switched to Verizon for this device when it came out so first time with Verizon. I get better 4g LTE connection at home but I've noticed in stores I get only 1x (is this Edge type of network compared to AT&T?) Or maybe 1-2 bars of 3G. Only get 4G LTE when outdoors. Even inside huge Target, Wal-Mart, whatever get cfao reception when on AT&T this was never an issue. This might be a carrier thing though, nothing to do with this device but again nothing to compare to, first device and time on Verizon network. Surprising too living in southern California where LTE is literally everywhere here. Actually had much higher hopes for Verizon network, feeling let done here.

Phone with best GPS Reception

I fly alot and I like recording GPS tracks in planes. I previously owned an HTC Incredible 4G LTE. If I had a window seat, I'd nearly always be able to get a GPS fix. Though I think it could be even better.
I recently upgraded to a new phone (Xperia Z5 Compact). The GPS reception sucks. It seems like every time the plane turns, I lose the fix. However sometimes for long stretches it still has no signal, even pressing the phone up against the window. Using my old phone, it still has a good signal.
I've given my old phone to my parents. I could buy a bluetooth external GPS, however, I got thinking and I could save money and buy another HTC Incredible 4g LTE for cheap on ebay for maybe $50. That got me thinking, maybe I could buy an old used phone that has even better gps reception and use it only for GPS logging.
That's why I ask which phones have the best reception. (Note, in a plane, A-GPS doesnt help)
