Z2 problems - Xperia Z2 Q&A, Help & Troubleshooting

My partner has had her z2 for a couple weeks. And she has always had iPhones and me mainly androids. But she has found it hard to use at times. For some reason 3 or 4 times a day over past week it has crashed and not responded. And also turns it's self off. And while in walkman app could not select songs only way I managed to get it to work was uninstall all updates then the songs were clickable. Then upgraded again and it still worked. Any one else had similar problems? Thanks

You shouldn't be having these issues. In my experience the phone is very stable.
The only time it resets on me is when I pull the SIM card. I'm not sure why it does that because it's not necessary.... But anyway
Try doing a factory reset and all that. If there are still issues call Sony support and get the device replaced, or just do a 30 return/exchange.

Yes i had these exact issues with a defective unit, it seems that replacing the device fixed it alltogether
Take note reflashing my firmware didnt fix my problem, if it doesnt fix yours then get a replacement

Xperia active randomly rebooting

Hi guys sorry to bother but there's an annoing issue going on:
_the phone: rooted xperia active,stock 2.3 with .62 fw and 2.9 rage kernel.
_the issue: when inactive, phone randomly reeboots,mostly when in pocket [never while using so far].All started a few days ago after installing a few new apps,i pulled the phone out of pocket and it was booted in temporary debugging mode.i rebooted and all the widgets went bananas.replaced them,and since every time i take it out of pocket it's askin for pincode.never rebooted overnight while chargin!also the calendar app would crash every launch.
_Solutions attempted; wipe data/cache and dalvik.uninstalled one of the above apps(it had root access,the other 2 are games…)and the semc.calendar.nothing worked…also i am experiencing major unusual batt drainage...
Any help will be much appreciated,thanks in advance.

Probably one of your newly installed app goes haywire.
Is there a log where i can see what is causing the reboot?i haven't done backup for a couple weeks and wold like to solve the exact issue without full wipe and recovery backup...the apps i didnt uninstall are popular (alchemy,doors and a.b.space)could it be one of these?ran virus check,only a trojan in winamp but pretty sure it's a fake positive...

I have the same problem with my xperia mini pro sk17i on stock firmware 4.0.4 from sony. I update my phone few times with OTA and Flashtool and thats don't helps.
Now I have rom Icshybrom v2 and all works perfectly.
I also did ics update last week but reverted back to gb the next day,i don't think the rom or krnl have anything to do,phone worked fine up to 2 days ago!

Little update:uninstalled all recent apps,the problem remains...if one of the apps was faulty wouldn't the phone reboot also when using it?it ALWAYS happens when in idle!this morning i unplugged the phone from charger,put it in pocket and 2minutes later was rebooted with battery at 91%!(no usage at all!checked 4 missed calls and sms and that's it).yesterday it rebooted twice and then was fine for 12hrs,sometimes it does it 4 times in 1hr,it's completely random,just never happens when using the phone...

Maybe there is something in your pocket that makes your phone randomly rebooting...try to leave it on a desk for a few hours to test it whether it is rebooting or not
XDA Premium sent this message from owner of Sk17i
I thought it could be a hw issue,but i slammed,shook and pressed hard all over and no probs,i even added a lil piece of paper to completely block the battery,but to no avail...could it be that these days i'm in a place with no 2g signal at all?faulty sim card(it's 10yrs old)?i looked all over and there's tons of people reporting this problem but all posts end with no solution.it rebooted also when laying on the table,never on charge!as soon as i disconnect from pwr poof!this morning had 4 reboots in 30mins,yesterday only two throughout the whole day....

Well i already hear about restart by bad sim card. If it really so old can you try your mobile with another?
Sent from my ST15i using XDA
It seems like it's the most plausible thing,i'll try and report.what about it happening mostly when there's no signal?could it be something in the phone tryin to force connection?is there anyway to get a reboot log?i found an app but it's all in jap...
Sent from my ST17i using XDA
Ok after a few days of investigations i can now affirm that the rebooting occurs 99.9% of the time when there's no signal at all. I'll try with a new sim card and see how that goes

Random Reboots.

I have been getting allot of random reboots, not while actually using the device but when it is just sitting there, on charger and off anyone have any experience with this?
Are these full reboots, with the LG and AT&T boot animations, or is it just the UI reloading? I havent ran into this at all on this phone. However, i have had an issue with the UI reloading with every Samsung device Ive ever had. Not sure what causes it or if your experiencing the same thing.
They are full reboots I normally catch it on the LG logo,I guess if no one else has come across it I'll go swap the phone out for another. Though my LG g2x had reboots till we had custom roms....

I went and exchanged my phone today for another, so we will see if that helps it. I am not sure though because I had a LG G2X and it had random reboots as well, it was only fixed with custom roms and kernels later so assuming we get unlocked bootloaders I am sure that will be fixed but till then I am not sure if I am going to keep this phone or not....

Your talking about "redraws" it has to do with the launcher (TouchWiz) or in some cases, RAM.

Where as I do not use the stock launcher, I use NOVA and well we have 2 gigs of ram... Plus mine have certainly been full reboots and the G2x did this same thing... we need to just hope for am unlockedbootloader.
I have had 1 random reboot so far. Hope it doesn't happen again.

I haven't seen any on my device. 11 days. Stock launcher.
All stock since Nov. 2nd. Zero reboots.
I returned my device for another, haven't seen a reboot so far.
Sent from my LG-E970 using xda app-developers app
I've had reboots as well. Around 4 times now and purchased the phone nov. 3. a couple times it was when the phone is just sitting there on stand by. one time it was while posting a picture on instagram. Another was taking a picture and looking at the photos... and when it does re start, it will restart 2 or 3 times at a time, like i see the lg logo 3 times, then finally the "rethink possible" logo, then the phone boots up and while or just after my media scanning of my sdcard finishes, it will automatically restart again... and this happens 2 or 3 times. for some reason I feel like it has something to do with me 64gb sd card but am not sure, i used to think it had something to do with eco mode but phone has restarted while it wasnt activated too... dunno how to fix, hopefully an update will come for a fix :/

Same here. Must have been a hardware thing.

I'm going to have to send mine in for warranty too, put a reboot logger on it and it's around 4-5 times per day. I should probably unroot it before I send it in I guess.

Lumia 920 Freezing - Any fix for this?

So I've only had my Lumia for 5 days but from day one it's been randomly freezing no matter what I'm doing, be it texting, web surfing, anything. I downloaded the software update and the problem persists. It happens several times per day and I have to soft reset which erases some of my settings, its totally annoying. Is there a fix for this or do I have a defective device?
Try a hard reset which unfortunately will wipe everything from your phone back to factory settings, If problem still persists then you definitely have a faulty device and should return it.
Set your highest data setting to 3G. This will disable LTE but for me it seems to solve the problem. Let me know if this works for you.

Sorry...disabling one of the best features of your phone to get it to work correctly is not solving the problem. You have a defective unit plane and simple

Yeah I'm sending it back tomorrow lol. I was just thinking the same thing. Nokia wanted me to remove skype cause they said that was causing it, then they said the facebook app was causing it. It's like ok, I have to disable Facebook, Skype, and IM+ to get it to work? What's the point of this damn phone? lol. Yeah my device is defective.

I know for a fact my device isn't defective because mine didn't start freezing until the portico update.

You missed my point. Disabling any stock feature of the phone to get it work properly is not a "fix", it's a bandaid. I stand by my statement...defective. Whether it be the hardware or software...still defective.

If you have a sim card that does not support LTE then yes it is a fix. However. I have also installed the portico update, 4G disabled and the phone went from never rebooting or freezing to reboot 2-3 times a day and at least 1 freeze.

[Q] Slow wifi

Hey guys I just picked up the Z2 the other day and I'm loving it but I'm having an issue with the wifi, it's really slow. (about 2mbs when it should be about 30mb) However the issue goes every time I turn the wifi on the phone off and on again. I'm sure it's just the phone as well as I have other devices connected to the router which run at the correct speed and I've tried resetting the router as well as forgetting the network on the phone but still the problem persists, anyone else found this problem with their device and found a solution?
Ive ran into the same issue with my Z2 and S
I found that after purchasing my xperia s i ran into this issue , after a few months it fixed its self
This could be because the device needs a run in or the firmware
Id recomend waiting a tiny bit to see if updates will fix this issue
Im waiting for my actual Z2 to come so i can conform this, for now im stuck with a dev device between me and someone else
Id also recomend googling about this as many people have this issue and it seems to be a firmware issue over a device or hardware issue

I just went to settings-backup and reset-factory data reset, I'm not sure I can recommend this method any more though as I've noticed my wifi speeds have dropped again today and yesterday. I'll keep a close eye on the issue though

Camera Shutting Off Due To Temperature?

Madly in love with this phone, but took it out to italy last week and took some shots on it and constantly a pop up telling me the camera was being stopped due to extreme temperatures
The phone was warm, but not very hot and I had only used it for one or two shots when it did this, repeatedly
Anyone had this issue?
I had this with my original Z2, i got a replacement and havnt had a overheat not once
Early batch devices have this issue the most
