[Nexus S Q&A, Help & Troubleshooting] vladkor:
Hello folks,

I am having a couple of really strange and frustrating issues with my Nexus S on WIND Mobile (GTA). I've read a few posts and while some of the issues seemed similar, they did not really capture the exact issues and did not have any real fixes. I am hoping that I am not alone with these issues and that there may be a fix at some point. Considering that Samsung does not honor the SNS warranty in Canada, I am SOL if these issues are just with this particular device.

My Nexus One does not have these issues. (Don't get me wrong, my Nexus One still has issues with WIND's network at times, but I have not been able to reproduce these particular issues on the Nexus One).

Anyways, on to the issues:

1) Connecting to 3G after a reboot is sporadic.

Issue: After reboot, the phone makes several attempts to activate the 3G data connection. The 3G icon appears for a second or two, the uplink arrow lights up and then the 3G icon disappears. The phone will wait for a 30 seconds up to 5 minutes and then repeats the attempt to establish the 3G data connection. More often than not, it will connect. However, at times, it will continue this cycle for 30 minutes; sometimes it won't connect at all.

Steps to reproduce: Turn phone off/on by holding power button or by pulling battery and reinserting.

Steps taken to attempt to fix:

- factory reset (Helps for the first boot - phone connects almost right away. Subsequent boots have the above mentioned issue.)

- wipe cache (no effect)

- triple-checked APN settings

- set WCDMA-Only via Testing menu and update SMSC (I saw this thread here but it didn't fix my issue.)

- setting network selection to Auto

- setting network selection to 302490

- turning Airplane mode on/off after reboot does not help establish 3G connection (edit 2011-01-25 @ 12:39 EST)

2) 3G Data connection hangs with uplink

Issue: At random times, usually after extended periods of inactivity I will unlock the phone and find that the 3G icon in green (as if it is connected to Google's servers correctly) and the uplink arrow lit up in green as if some sort of data activity is occuring. However, opening up the browser (or any other app that uses data for that matter) will result in a time-out error as if the data connection is not working. The uplink arrow will stay lit up anywhere between 1 to 10 minutes. After this time, the 3G icon will turn gray and data will once again start working.

Steps to reproduce: Sporadic; extended periods of inactivity and potentially walking through an area with bad coverage will trigger this issue.

Steps taken to attempt to fix:

- turning Airplane mode on/off (Turning Airplane mode on causes the data connection to hang entirely forcing a reboot. Airplane mode will not actually turn on and will not be possible to turn off. Have to reboot to restart connection.)

- placing phone call to test network (Sometimes call will connect, other times call will hang at "Connecting". At that point it is impossible to disconnect the call; pressing end call results in "Disconnecting" forever. Only a reboot will reset data and phone app.)

- turning 2G only on (see Airplane mode)

I am hoping that somebody can coroborate these issues and/or point me towards a fix. (Are there any custom ROMs that have shown better 3G performance?)

Thanks!
