Problems after upgrading to Kit Kat - Xperia Z1 Q&A, Help & Troubleshooting

Hi there, ever since I upgraded my simfree Z1 C6903 to Kit Kat, my phone spontaneously switches off its wifi and sporadically drops the brightness down to its lowest.
This happens a few times an hour when I'm using my phone for browsing and chatting on text apps.
Every time I have to push my brightness back up and switch wifi back on.
They both change at the same time....
Anybody else encountered this problem?

I don't have any problem. How did you upgraded?

[Q] GPS and BT bug

I'm having a strange bug where when I use the gps and bluetooth for prolonged periods, the radio seems to shut off. This only happens when i'm driving from Oregon to California and I use the phone for music/audiobook and as a gps for time remaining in the trip.
I'm using Navigation for the gps and the standard play music for bluetooth music. I'm driving a Subaru and have never had this issue before. By the way, the phone gets 7 hours + for gps if the screen isn't kept on the entire time, much less if it is but still over 4 hours.
My xt890 is is not unlocked and is still completely stock. It also randomly shows a G where normally theres an edge symbol since I restrict my phone to edge because the Tmobile roll out hasn't happened in my area yet I don't think (Phone doesn't get 3g ever).
When the bug occurs the only method I've found that fixes it is to reboot the phone, airplane mode and back does not fix it. Though after the bug occurs once, it seems to happen more frequently. Could I be overheating something?
I experienced problems turning on gps on my RAZR-i twice in the last 2 weeks. I am using CoPilot live for navigation. In each case turning the phone completely off and waiting a few minutes solved the problem. In both cases I had the phone on (T mobile) and was using wifi for an extended period of time. I believe something is overheating. Don't think a HW problem, rather firmware reducing power to stay within the power budget (not enough for gps), but I am not 100% sure...

Ok- yesterday the gps stopped working completely.
After doing a hard reset all problems are gone now.... clearly something got corrupted. Question is what app caused all my problems. Anyway, I am glad it was not an HW issue (imported it from GB to US)....

Xperia TL (LT30at) sleep of death issues

So, just this last week after having my new Sony Xperia TL for a month I started experiencing the sleep of death issues, I haven't tried to do the restore via PC companion yet, if it does it again tonight I will. (I'll probably want to do that before updating to JellyBean anyways).
So far it's only happened at night, when on the charger for four+ hours, it's been hit and miss, happened two nights in a row, then worked two nights in a row, then locked up again last night.
The locked state; the screen is off doesn't respond to lock button, the notification light is blinking. I have to reboot it with the Volume Up + power button.
I thought I had fixed it by removing the PSM store (Installed that shortly before this fun started)..
Any other tips?
here's some links:
Xperia V sleep of death
http://talk.sonymobile.com/thread/60422?start=0&tstart=0
So, on Saturday (when I posted this) I disabled the ATT wifi hotspot software, and also in the apps section of developer options;
Checked "don't keep activities"
I'm not sure if I've solved the problem but the last two nights it hasn't locked up and yesterday the battery life was the best I've ever had.
I have only experienced this with wifi on. So long as wifi is off, it's not had a SoD issue. Irritating.
Seems legit

That's what happened to me just now. I checked "don't keep activities" but left wifi on. I'll see if it happens again. No point in having a smart phone if i cant use my wifi.

Did you have any more sod issues?
Since I've rooted and installed XperimenT version 1.7.1 I haven't had any sod.

Sod returned for me last night.
The only thing I changed yesterday was installing dead trigger. I rebooted into recovery and cleared the cache and dalvik.
I saw this thread for the v and noticed that this is also in our Rom.

Might be worth a try.

I have had the TL for about a week now and have had this sleep of death happen twice. First time it happened i was charging it during the day with a little bit of use here and there. The second time it happened was overnight while i was sleeping. I was depending on the phone's alarm to wake me up, it never did. Woke up an hour later on my own and luckily wasn't late to work. I read somewhere else that killing active apps before putting it on the charger helps. It's been two night using this theory and so far so good. I am not rooted or unlocked. 1) Does anyone know if this is a hardware or software issue? 2) Should I return it for another device? I have a few more days to return it if need be. 3) Does the update to Jelly Bean bring a fix? Rumor has it March 12th is when the TL gets JB.
Oh and I have wifi on when I'm home.
No jellybean doesn't fix it. I'm running rooted jellybean (xperiment 2.0).
Friday night while charging it did the sod. I didn't change anything and its been fine the last four nights. I have no idea what causes it. I thought it was the line in build.prop, but not anymore.

Sod this morning, made me wake up late.
I'm gonna have to play with the settings see what I can figure out.

Have you tried leaving wifi off?

Turned it off last night and the phone didn't SOD. The interesting thing is the night before I checked my phone about an hour before my alarm was supposed to go off and it woke up fine.
Any idea if it is wifi, why? Is there a build.prop tweak we can do to sort this out?
I have been keeping my wifi on for the last few days, and so far no more SOD. Only thing I have been doing is clearing any active apps before going to bed. As long as this keeps working, I'm good with it. Think it's been about 5 days so far. Will post if anything changes.

If clearing active apps keeps it from locking up, one of the apps has to be the problem. Wonder if it'd be worth posting an app list?

I downloaded a system cleaner Friday and since I've run that there hasn't been any sod.
I've left WiFi on overnight all four nights.

So in my drunken state last night I forgot to clear my apps before passing out. I did not get a SOD. I probably got lucky. I also want to throw out there that the first week of ownership, I kept everything stock and only added my email apps since I heard jelly bean was coming out. I always do a factory reset after a big change in OS, so I didn't want to have to set up all my screens again. Anyway, I hot my SOD's during that time. So I think the issue is bigger than an app related one. Maybe the Jelly Bean update fixed it.

Seems like the consensus on the net is leaning towards Wifi setting "don't keep activities" for solving this. Just picked up my V last week and promptly had 3 SoD's after changing the wifi setting to "only if connected". Yesterday switched back after some searching and so far no issues. We'll se how it goes coming week.
BTW, my phone came with latest 4.1.2 and still has.
Since I've installed that system cleaner app, the phone hasn't locked up overnight.
I have wifi set to location mode, which seems to turn wifi off when the screen is off.
So, it's either a file problem, or a wifi problem.
Up time; 83 hours, xperiment 2.3.
I'd be curious if anyone with sod, flashed cm10.1 and still experienced them.

My guess is the latest Sony firmware has solved this problem. I haven't had any strange settings since anything above .141 and have not had any SOD's.
even i am using the TL... haven't experience a such issue yet.. but one thing.. mine gets heated very soon and battery drains really fast..can notice it clearly

Stock ICS Bugs

Does anyone else think this update was half baked?
I'm having a lot of issues with the new update. Bluetooth keeps skipping like a scratched cd, Wifi won't connect just keeps requesting ip from router then I have to shut off wifi and turn it on manual to connect, I really need to fix these problem any suggestions.
Can I roll back to 2.3 stock some how?
Are there any other good forums for this phone?
I love it. No problems with Wi-Fi. As a matter of fact, to get Wi-Fi to work in gb,I had to reboot the phone everyday. Also no ghost calls. Being able to turn off data and Wi-Fi manually gives me 2 days of battery life.

Xperia V spontaneous self reboot issue

I'm using the Xperia V running the latest Jelly Bean stock firmware (see my signature). I while ago, my phone started to spontaneously reboot itself, sometimes during standby, sometimes while I had the screen on. I know that others had this issue as well, but none of the threads I found were really helpful.
I can't really explain this, as I didn't change anything in he past couple weeks. The only thing that happened was that I once dropped from about 1m in our living room, but I doubt that that would cause such a problem.
As for software, I'm using the Aviate launcher, and I have Android Tuner installed which helps to keep my memory free and reduce battery usage. AT is set to kill background processes when the screen is turned off, and important processes are all excluded from that. But again, I haven't changed anything in the past couple weeks before the reboot issue suddenly appeared, so I doubt it's any of the software I use.
So, does anyone have any ideas as to what might be the cause of this? It seems to happen less frequently when using WiFi instead of 3G. Might 3G be the cause? (I'm just guessing wildly, I really have no clue as to what causes what in an Android phone.)

Wi-Fi won't stop turning on after root. Any ideas for a fix?

I updated to the first ota of kitkat when it went live and really didn't like it, so I downgraded to the first firmware, then accepted ota til I was back to 3.05.651.6, and now my Wi-Fi won't stay turned off no matter what settings I have chosen, and it won't respond to BatteryGuru like it used to before the whole mess.
Anyone have any ideas as to what may be causing it or how to fix it?
