SIM 2: Cannot switch back from 2G to 3G / LTE #35

Closed stucki closed 8 years ago

stucki commented 8 years ago

I added a new APN for the 2nd SIM card. Not sure if it's because of that or not, however:

Since then, the 1st SIM was had network turned off. I could only fix it by changing the network mode to 2G. However, now I'm unable to switch back to 3G or LTE. It doesn't work through settings and it neither works using the *#*#4696#*#* menu. Also in logcat, I don't see any errors.

Can anyone reproduce this? I already tried deleting /data/data/com.android.providers.telephony/databases/telephony.db but that didn't help.

stucki commented 8 years ago

Hmm, don't know if this problem is really device specific or not. At least, I found a simple workaround for it: I turned the phone off, swapped the SIM cards, and booted again. LTE was immediately working again. So I turned the phone off again and swapped the SIM cards back into their original slots, and it looks like the problem is gone. I am now able to switch from LTE to 3G and 2G, and back to LTE without problems.

However, it really seems like the APN setting for the 2nd SIM card is somehow related to the problem. I notice that I can't select the new APN that I created before. I reverted APN settings to the default for now but will try again at a later time...

cmorlok commented 8 years ago

This is not APN related. I am having the same issue, but I didn't change any to APN setttings. All I did was to enable 4G on the second SIM. Seems like there are more upstream bugs to address.

Workaround: remove the non-data SIM, set data to 4G, insert the non-data SIM again (no need to reboot, hotswap is working).

cmorlok commented 8 years ago

This might be fixed by http://review.cyanogenmod.org/#/c/128511/ and http://review.cyanogenmod.org/#/c/128512/

I will test it tonight.

stucki commented 8 years ago

Seems to work now. I cannot reproduce the problem anymore. Also the SIM preference is now preserved after reboot.

cmorlok commented 8 years ago

Hi @stucki

Are you testing my build, or did you build on your own?

stucki commented 8 years ago

I'm using my own build which was built yesterday night.

stucki commented 8 years ago

Hmm, the problem is not fixed. Just had the same issue again on the other SIM card... :-/

piwats commented 8 years ago

Can confirm, same behaviour here. cm-13-20160120

piwats commented 8 years ago

39 seems to be very related, because when I try to change the network type from 2G to 3G or LTE, I start to see segfaults of android.settings in dmesg:

That one particular happened just during the switch to 3G or LTE from 2G:

cmorlok commented 8 years ago

Is there anything shown in logcat at this point in time? (either "logcat -b system" or "logcat -b radio")

piwats commented 8 years ago

@cmorlok: I'll do. However, it will take some time, as I have tried out cm-13.0-20160120 yesterday just of curiosity. At the moment cm-12.1 is back on the phone again. Maybe tonight I'll flash it over again.

piwats commented 8 years ago

Ah, and android.settings segfault errors are also the same to observe as previously shown...

cmorlok commented 8 years ago

@piwats Can you describe exactly (step by step) what you are doing before you get this error? I cannot reproduce it.

piwats commented 8 years ago
  1. I switch card2 to 2G if it was LTE.
  2. I try to switch from 2G to 3G or LTE back. With no result, Bering stuck in 2G.
piwats commented 8 years ago

I've forgot to mention I use 2 sim cards. card1 only for sms/voice, no edge,lte, or co. card2 is LTE only.

piwats commented 8 years ago

cm-13-20160131:

dmesg gives during the start a ton of those segfault errors.

Now the behavior has changed:

When I try to change the network type from LTE to 3G nothing happens, apart from m.android.phone faulting again.

Although I see LTE in the setting of the 2nd card, only an "E" is displayed. So is the speed. At the moment I can't get LTE to work.

piwats commented 8 years ago

It seems to be a CM13 related bug. I have reports on the same behavior on CM13 nightlies fot the Moto G 2014.

piwats commented 8 years ago

Behavior confirmed over at http://www.htcmania.com/showthread.php?t=1130019&page=21

piwats commented 8 years ago

Similar situation described here:

http://forum.xda-developers.com/nexus-4/help/cm13-switching-to-wdcma-t3280353

And a patch is provided here, has to be changed accordingly:

http://review.cyanogenmod.org/#/c/125897/

cmorlok commented 8 years ago

@piwats That patch is for #30 and has already been applied. This bug here is only for the second SIM (I have changed the title to make that clear). On SIM 1 you can chose any network mode including 4G.

piwats commented 8 years ago

At the moment, with cm13-20160130, I can't choose the mode even on sim1. At the moment it is stuck with LTE; 3G or 2G cannot be chosen. The signal status shows me an "E" while the sim settings shows me that LTE is chosen. Also the behavior is the same as sim2 at the moment.

dmesg shows task.ti and android.settings segfaulting all the time. I have no idea how to debug further.

piwats commented 8 years ago

aout the patch: I looked through cyanogenmod sources of various devices. It seems that most of them have not applied it.

At this point, does it even has an impact?

cmorlok commented 8 years ago

Has been merged upstream and will be fixed in the next build: http://review.cyanogenmod.org/#/c/126364/

Before this change, we would have to set ro.ril.multi_rat_capable to true to enable 3G/LTE on SIM 2.

It's still not perfect, you will have to change SIM 1 to 2G manually before being able to set the network mode on SIM 2.

piwats commented 8 years ago

Yay! That's something.

However, why is there this problem which seems not to be in cm12.1?

piwats commented 8 years ago

cm-13-20160207: Improvement is evident. LTE sim2 is back again and working. Though sim1 has to be in 2g mode.

This can be understand as a workaround. Still, improvement is needed until on par with cm12.

starvoid commented 8 years ago

I'm using the cm-13-20160207 image.

When I try to change the network mode of the SIM2 from 2G to 3G or LTE, it seems no has effect. The same interface works fine for SIM1.

Thanks for your effort and good work.

Please, find attach the logcat in that moment:
