Help "No sleep" problem on JC1

[gil1]

Hi,

From what i've seen so far, JC1 also got the same no sleep issue, Crap!

 

[apolloFER]

Tnx for the info. Looks like I'll remain on 1.5 for a bit more.

did they fix slugishness?

did they fix slugishness?

It is pretty fast form what i experienced so far, but i use advance task manager to kill un-needed apps and setcpu to overclock with on-demand profile.

does the market still hang for a while whenever starting a download or installing app?

 

[gil1]

Market Still Hangs but Light Sensor is working properly.

 

[mrqs]

too bad - the market hang is the only trouble jb2 is giving me

I've done some test today, my conclusion that the sleep problem is caused by GPS and Wireless network location.

I rebooted phone, Phone sleeps.
Turned on GPS, started GPStest and got a fix, turned off GPS... phones doesn't sleep.
Did the same with Maps and Wireless network location.. same result.
Rebooted, didn't touch GPS whole day, phones slept like a baby.
This was repeated to confirm.

I've intermittently used GPS and use wireless network location all the time, but I don't have the sleep problem (neither on JB1 nor on JC1)

However, I keep my apn off most of the time (apndroid), I'll try with 2G only (to save battery) and see whether I now get the no sleep problem too

What phone version do you run?

On JB2 we had the no sleep issue for a week but after switching off wireless location and 'allow google to use locaion' it has been sleeping fine, but what id like to know about JC1 is if the unbarabley slowness has been fixed. After using JB2 for a few days it now takes about 15 seconds to open spareparts and even opening a txt message takes ages. Has anybody seen this on JC1?

 

[gil1]

The speed of JC1 is good. I recommend to use "setcpu" to tweak the clock and then it is even better.

 

[inFECT]

Its confirmed that both settings are not fixing the sleep bug.

Speed is not really improved. Spare Parts & Co still needs longer to start than on 1.5

What phone version do you run?

By the way, I _haven't_ set 'allow google to use location'.

However, if the 'wireless location' setting really fixes the bug for you, does 'wireless location' work for you? (for me it works fine). Otherwise it might be a bug where your phone encounters an error trying to compute a location. Maybe the location reported by some gsm antennae is faulty?

I think everyone with the bug should write in which country and with which service provider they have this problem, that might shed more light on the source of the problem.

Well, i posted this allready elsewhere, but my location provider is flooding my log... even when iam not get hit by the sleep bug.

inFECT, how do you access this log? I'd like to check if I see something similar.

 

[inFECT]

it's a simple "adb logcat" via SDK. Check out the FAQ/Tut Section to get it running.

 

[dryhte]

FYI, I'm now at home and my phone is just lying next to my computer. I've received a couple onCellLocationChanged messages and a load of GC lines, but now after a few minutes, no new log entries have been generated. When I press the HOLD button, I get some new log lines about processes that are started and stopped again, but then it goes back to good old idle.
I assume that maybe you live in a location where it's hard for the phone to decide where it actually is (maybe just in between of two gsm antennae, or so)...

 

[inFECT]

Nah, i live in a big city where my cell provider is located. I have full coverage.

I never had these message on 1.5 Roms.. I tried also to change the mobile network. (diff. provider, different frequences) and the log flood remains.

and btw iam pretty sure that these log entrys are not really keeping the phone from sleeping, because i have them always even when the sleep bug does not appear.

Network location works fine but after an application the phone stops sleeping. If no application has used it the phone sleeps good.
How do i get the extra version info? (i use *#1234# and get only 3 pda, phone and CSC).
