Signal Drops on Wind Mobile

Hi guys,
I'm on Wind mobile in Canada (london), running AOKP 32 with franco kernal milestone 2. I've been noticing that my nexus completely drops signal once or twice a day and then picks it back up after a couple of seconds, while I'm using it. I just bought the phone about a week ago and was quick to put on 4.0.4. I've also tried the ugla4, uglc1, xxla2 modems with the issue persisting. I'm really hoping this is a software issue related to 4.0.4. Is anyone else having the problem?

That was the first thing I tried! I'm still surprised it didn't work.

Roman himself has signal drop issues with AKOP ... i haven't had a single issue on CM9 where i have on different roms ... i'm using UGCL1 radio on Rogers and in London as well

Try setting your min CPU to 700

disabling smart reflex is usually a better option then increasing the min clock speed as that will decrease battery life. Fugumod kernel has smartreflex disabled.
I have been having this issue, although since flashing AOKP B32 and stock kernel I have not been having that issue. I wonder if he changed something in the last build. Also using UGLC1 radio.

I switched to CM9 after you suggested it might be an issue with AOKP. It's a little early to tell, but I've been using CM9 for about 2 days without any issues. It looks AOKP may have been the culprit after all.

[Q] COS-Bravo-ICS - problem reconnecting with 2G or 3G after Wifi connection

Hi,
I'm using the COS-Bravo - ICS [21-May-2012] on my phone. Since the first version I flashed I've been having the same problem, but as the ROM is under development, I thought the problem would get fixed in some update. It still hasn't so I'm reporting it.
When loosing a WIFI connection, the phone must switch to a 2G or 3G network. This doesn't happen. Mostly the WIFI icon disappears as it disconnects and the signalstatus doesn't change (no Edge, Gprs or Hdspa is added). When I go to Airplane mode and back or when I switch between 2G/3G, the connection is repaired and the data-connection works again.
I've also noticed this problem with other ICS roms (Sanvold and BCM)
Does anybody have a clue what this could be?

Radio
What radio version do you have?
Its recommended to have the latest radio.
You can find the latest radio here: http://forum.xda-developers.com/showthread.php?t=687464

Of course the latest radio. ;-)

I have the same issue. When turning wifi off, my Desire doesn´t get a mobile connection though it´s showing, that i would be connected.
Switching to 3g and back doesn´t work for me.

Same problem here with Sandvolds ICS
I have this problem nearly 2 years now on every rom (stock eclair, froyo and cm7) and on every radio version, so I guess it is hardware depended.
Correct me if i am wrong.
What I do is switching to airplane mode and back, so i have to enter my PIN again.
Maybe there is a soltution, cause this is really drving me nuts
Thx

With the newest version (01-06-2012) the problem seems to be solved (for me). Perhaps you should give it a try.

I´ve been glad to hasty. It still does not work. Neither does it to switch between 2g and 3g. But the airplane-"hack" does work for me too.

I have same problem with COS ROM. Mobile internet connection after using telephone as wifi modem do'nt working successfully.... i need reboot phone, airplane mode not solving this problem..

Hi!
Same problem here (HTC Desire Bravo, GSM, Cos-Bravo 1st June, latest radio).
This "bug" is present in every ICS Rom and as well in some GB Roms I tried. So far, the RSK ROM Sense 3.5 with amaze cam doesn't have this issue.
I hope someone will get to it. I'm more than ready to donate if someone will be able to solve this out with next build.
Thanks.

To judge from my own experience - I'm still seeing this problem six months later - it has not been fixed yet. Or does it only affect a subset of Desires?
I'm experiencing it using a GB ROM - Mildwild 4.7, though it was there in 4.6 as well. I can only assume it is in the ROMs, as I get it on two different handsets, a PVT3 running radio-5.17.05.23 and a PVT1 rrunning radio-5.11.05.27.
cheers,

Remove the skipbrokendatacall entry in build.prop file. This will not completely resolve the problem but will make it very much manageable.

Check your APN Settings and try to set APN-Type to default only.

[Q] Keep Wifi alive on JB

I've upgraded to JB, and absolutely love it. Only one thing I cannot figure out after searching extensively and trying out countless apps, is how to force WiFi to stay on at all times. I need it on for incoming VOIP calls. Seems that for me in JB that is really hard to accomplish, where on 2.2 and 2.3 I had no problems. I'm running JRN84D JB with the 3.0.31 Franco kernel on a GSM GN.
Any help is greatly appreciated!

Have you checked Settings > WiFi > 3 dots > Advanced > Keep WiFi on during sleep?
From what I understand, from Honeycomb on, even with this option enabled, Android has been programmed for this option to only use low performance WiFi, meaning that it is throttled and can stutter or even disconnect. Applications that are properly coded for Honeycomb forward should call "WIFI_MODE_FULL_HIGH_PERF" if needed, which will lock in high performance WiFi during sleep. If this isn't occurring, the developer of the app will need to be contacted to resolve the issue.

Thank you very much for your detailed answer. Yes, my settings are indeed correct. I also tried the app you suggested, but still no success. After 15-20 minutes of inactivity, wifi always gets turned off. I'm baffled.
Does constant-on Wifi work for anybody on JB? If yes, what rom are you using? Any special tricks/apps?

I have the opposite problem with JB, even my wifi policy is keep on while sleep only when plugged in, but my wifi seems to stay on all the time...
FYI: I am on stock JB flashed with CWM, didn't flash the new radio yet so I am still on I9250XXLA2 from 4.0.4 yakju

I'm using the same ROM, but I did flash a new radio (XXLF1). I will try and flash a different one. Maybe that'll be a clue.

On completely stock 4.1 GSM and my WiFi just stays on while sleep just fine.

Can you let us know your results?
I'm having a similar issue with WiFi not connecting when i get into the office, event though the router is behind me, and visible.
I've turned off the "don't connect to poor quality networks" option.
Does anyone know the exact functionality of this feature? What defines "poor quality"? Does the phone run a test between your phone data speed vs. the WiFi speed?

Initially when I installed JB (v1 for Verizon) I couldn't get WiFi to turn off. It's doing fine now on v3 with all the little fixes patch.

GPS keeps showing "Searching for GPS"

Navigation is stuck on "Searching for GPS". Is there a fix to this?

I know there is a fix around the forum somewhere for it. You might want to give us some more info like what kernel/rom you are running. I am RasBeanJelly and franco.Kernel lastest of each and my GPS locks on in less then 10secs. More info about what you are running will help us out.

I recommend switching to a different ROM such as Codename Android. Some ROMS have a GPS problem like you are describing. The kernel has nothing to do with it. Hope I helped.

Its coming on all ROMS D:
Still getting same error even after trying CNA. I even went to GPS settings and checked "Internal GPS antinna" or something. But still getting same error. Could the phone be faulty?

Have you tried either of these?

i have had instances where it was a KERNEL problem..not the rom...certain kernels couldnt lock on GPS..flashed a different one and it worked..flashed back to test it again and it didnt...so it was definitely the kernel causing it...so he can try flashing another kernel

I upgraded to 4.2 jelly bean.. and I have gps proble, always searching for gps..
I had the same problem with 4.1.2 and maps 6.14 but with 4.1.2 I installed back old gmaps app (6.12) and the problem was solved.
Now I have 6.14 maps ad default.. and the problem is here.. how can I solve it? thanks

For me even the gps icon is not blinking. How to find whether the gps hardware is faulty? So that i can stop trying other software fixes

sygic works so it's not a hardware problem.. other gps apps show me satellites.. but maps no!
Old gmail maps works but now I don't know how to install previous version.. can anyone help me?
Maybe it's a app problem (6.14 maps..)
thanks

Install GPS status from market and let it download agps data and point it towards the sky and see how that goes. If you see satellites and they lock, go back to maps; it should work now.
Some gnex came with faulty GPS module. I have two gnex and e first one I got had the problem and hasn't been fixed with several ROM, kernel and tools and GPS scripts.
Keep us posted

gps status show me satellites.. sygic works but google maps no!!
I don't think it's a hardware problem because with previous version of maps it works! so I think it's a google maps problem.. but I don't know what to do to make maps work!

This is a Google problem, it's happened once before to a ton of android users, it may have come with an alert "unable to sign into account" (that's how mine was this morning, plus searching for GPS. All seems well now.

[Q] Bluetooth issue for MIUI Jellybean

I have been using MIUI 2.11.9 for my SAMSUNG i747. I was extremely happy with MIUI except for the bluetooth issue:
I have been using the previous AT&T stock version (Android 4.0), the bluetooth connection with my car can always stick. However, after I flashed to MIUI, the bluetooth connection will drop after several minutes' inactivity. I will have to turn the phone back on and reset the bluetooth to let them connected again.
Please give me some help! I have been googled and searched and couldn't find any solution. Does this mean it cannot be solved? Is this a Jelly bean problem or ROM problem? Is it possible to fix it?
Thanks a lot!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !

There's a MIUI update: 3.1.11. Perhaps that will fix your issue.

That's my bad, I did mean 4.2.1 - Altought, hadn't noticed that MIUI is on 4.1. In which, BT is supposed to be fine.
Either way, am I wrong or 3.1.11 is out? Pretty sure that's the thread I linked.

I tested recently and found it's related with "sleep" in the phone. Is there any way to set the bluetooth stay on while the phone is sleeping? Or is it possible to set the longer wait time for "sleeping", right now, the longest time is 10minutes in this ROM.
Thanks!!

You could use a app like Tasker to tell it not to go in sleep mode when BT is on.
