Mobile Data Problem

Since i bought my Xperia Z, i had a problem with my mobile data,as soon as i turn off my wifi my mobile data was unable to connect. This problem occured only sometimes sometimes it would connect and some times couldnt.

I had to restart my phone phone to connect mobile data . :(

I had this problem on 4.3 and 4.4 both. i flashed the customized US version and then the Indian stock version but the problem was on both.

Anybody having this problem .?

Re: List of all problems for Xperia Z

You wait to see the issues on the one once it's gets into peoples hands.

Early adoption has its problems. Hopefully a fix for these problems isn't too far away.

My only issue is that all of a sudden my Z stated getting some very low antutu scores. Used to get 20000 plus regularly but now struggling to get above 15000. Also Sony need to introduce an overview mode again. Flipping between screens can be a pain sometimes. Wonder why they removed it totally. I can understand getting rid of the silly floating widgets but no overview mode in android, ridiculous!!!
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
You're not, the phone might be. You have it brand new I see, things which take place during the first couple hours and up to first couple days:

All apps are getting "optimized"

dalvik cache is being built, data cache is being build etc

Whole device is being indexed

the more files you bring over from your earlier device the longer this takes and the higher the chances are the scanner will eventually hang/crash/fail

high-res pictures' exif data is being read

audio files are being indexed

video clips and files are being indexed and thumbnails created

Coming from a Galaxy Note, I noticed this with my T at first and now with the Z. WIFI reception is somewhat weaker on the Sony devices than it was on my Galaxy Note.

---------- Post added at 02:20 PM ---------- Previous post was at 02:15 PM ----------

Probably a) background activity eating cpu cycles away or b) power saving app limiting the accessible processing power. Or - dunno if the Z also has it or if it is only on the T - thermal throttling. On the Xperia T, to prevent device damage, the Snapdragon powers down until a lower temperature level is reached. If you do several benchmarks in a row this might step in.

Not to piss you off and it's rather a rhetorical question, but uuuhm... I wonder what the point is of running benchmarks over and over again :confused:

Re: List of all problems for Xperia Z

That's due to the AMOLED screen, as it don't have a backlight to drain battery.

Unlike the other makers
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
Well the Note 2 does have excellent battery life, that's well established. And I don't know how Samsung pulls that stunt off but they do :p

But still, I had the original Note and have access to a Galaxy S3 which is technically identical to the Note 2 and seriously, I prefer both my Xperia T and now the Xperia Z to them, with the faults and niggles both expose. Overall the current Sony's fit my bill much better than the current Samsung's.

---------- Post added at 05:11 PM ---------- Previous post was at 05:11 PM ----------

AMOLED consumes considerably MORE power than a traditional TFT panel. Hence I say, I don't know how they do it, but they seem to successfully do it...

The note 2 has a much bigger battery than most phones, no magic just more space to put more battery.

Sorry for off topic. Please could someone advise on how good the camera is ?

I have read and watched all the reviews but have seem mixed opinions.

[Xperia Z Q&A, Help & Troubleshooting] monologue:
Real problems I'm having:

- having to charge the device almost twice a day. If I force myself to don't use the device when I shouldn't, and only use it when really necessary, I just don't make it until the end of the day. I've unplugged my device this morning at 8 and it turned off by itself today at 6 pm.

Brightness is about 40%, 3G/4G hasn't been on once, manually turn WiFi off when not needed, didn't used the camera once, Stamina mode was on.

- SD card gets rejected about 2 times a day. It's a SanDisk microSDHC 32GB Class 10. I have tried to format the card, didn't help.

- The screen light goes on at random times. It doesn't show my lockscreen, it just shows a plain black screen, with the backlight on. It happened last night while my phone was just laying on my desk, untouched. I woke up because of the light.

Things that annoy me:

- The device gets hot after a couple of minutes. 3G/4G is off. Just using WiFi, browsing some websites.

- A LOT of apps aren't compatible. Apparently it's because these apps don't support 1080p yet. I know rooting the device would be a solution, but I'm not willing to do this (yet).
[Xperia Z Q&A, Help & Troubleshooting] Vivoin3d:
What else did you do in those ten hours?? How many hours of screen on? Because if it was in stand by most of the time, I can think of two reasons only:

- there is an app draining your battery

- faulty battery
[Xperia Z Q&A, Help & Troubleshooting] djbbt:
I am really disappointed with the camera, a half second lag between when you press the screen to it actually taking the shot, you miss the shot you thought you had. My friend came over with his Iphone 5 and it showed the Z up! Low light pictures, indoor pictures, iphone smacked it, the z does have nicer colours and if you set up your shot its a better camera, but for quick instant shots its usless.
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
AW: List of all problems for Xperia Z

On that usage pattern, something is very wrong! As a comparison my usage of today:

off the net for 16h

screentime currently at 1:45h

all power savers off

data on, wifi on, all the time

syncing 3 gmail, 1 exchange, 1 fb, 1 haxsync

some surfing, some calling, quite some whatsapp and a remote desktop session of ~15 mins

battery at 31%

and I just noticed I have 2h worth of wakelocks on top of that

Something is definitely very wrong.

Had the same card, failed on me in the exact same way as yours. Got it exchanged 3 (!!) times over a period of 3 months, failed every time again, exact same way. Now exchanged it for good against a Samsung 32GB card. All well since.

Oh, that was on the Xperia T, I don't have the Z since 3 months ;)

Well, getting hot when browsing is to be expected. The S4 Pro is a high profile platform and get's hot when being used. Chrome - which I suppose you use for your browsing - is quite a ***** on the CPU. I can't judge, how hot it really gets, but mine get's warm/hot as well when browsing, but I judge it as normal until now.

As for the rest and quite possibly some of the above I replied to with other quotes, I believe it can be attributed to your sdcard failing. Whenever the device loses the card and remounts it at some point, the system wakes up, mounts the card, the mediascanner goes all crazy re-indexing the card etc etc. Try to run the device without the card and see if the battery lasts better and if the undesired effects go away. And get it exchanged on warranty, from my experience with that specific type of SanDisk card I even say switch manufacturer. I went for Samsung, as Transcend & Co have a rather cloudy past and are known to be cheap but not that cheerful...

Try it and come back. Highly interesting topic, I'd like to help you get your device on track.

AW: List of all problems for Xperia Z

I have mine on superior auto at 9MP. Taking a picture is almost instant, very fast in any case.

Some hint's to speed up the actual process of taking a shot: Either use touch to focus to have focused already or touch-and-hold the "shutter button" to make the camera focus prior to taking a picture. Once you release the shutter button, the picture will be taken.

Note that my almost instant camera experience is without using above "tricks". I agree, launching the camera takes forever though :thumbdown: I get it's a mighty piece of software, the camera app, it's still not quite acceptable.

Set the Z to 9MP which is comparable to the Apples 8MP shooter.

I haven't tested it myself yet, but I keep reading that the Z's low light performance is sub-par. Quite a shame, yet perfectly understandable and logical as well. If you know very little about how cameras work, you'll be able to understand why. With such a small sensor size and 13MP, you'll never ever be able to get a decent low-light performance. That's against physics... But well, it's numbers, **** comparison: bigger is better. And with 13MP I believe Sony has the biggest one in the industry... I stand corrected if wrong, of course.

Consider the tips above and put it into 9MP superior auto. It should perform a lot better.

PS: do you capture to the internal sdcard or an external sdcard? If external, what make and type is your card?

Yeah, WIFI is poorer than on my previous Galaxy Note, also my Xperia T performs worse than my Galaxy Note. I have an ok signal in my whole flat, so I'm ok with that. It's still worse though, no denying.

I wash mine every day. I enjoy being able to wash off the dust which collects in the speaker and mic area, this always bugged me on my previous devices :D

Re: List of all problems for Xperia Z

I really-really-really-REALLY don't get why would people use antutu for 5 minutes, why would people keep on benchmarking their device again and again, if you benchmark it, let's say, 30 times is there any secret message coming on the screen "IT'S OVER NINE THOUSAND!!!!"

http://www.youtube.com/watch?v=SiMHTK15Pik&feature=youtube_gdata_player

and the phone will go Super Saiyan 5 form? You know, it quadruples the cpu power for defeating Freeza and saving the world? It's a SMARTPHONE, not a nuclear reactor, you don't need to see how fast it is all the time, if it doesn't feel fast then it's probably not fast, reboot and see if it get's better, or exchange it for a device that makes you happy, the only reason for benchmarking is you're actually a developer making a new OC kernel and wanna see both the benefits and the stability of the kernel, no other apparent reason. Anyway, enough of me ranting, from what I read here I guess I will not be buying this one either ever or just yet, my 2 main reasons were the camera and the waterproofing, if the camera is not really remarkable then I'll go for the Butterfly(import it), I like how the One looks but I think that little extra real-estate on the screen is what I want, plus I can actually have S-OFF now apparentelly, on the Butterfly that is.
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
AW: List of all problems for Xperia Z

Waterproof is cool, no internal corrosion when you carry it around in the summer in your sweaty pants pockets and its boiled in body steam. Yeah.

Also youtubeing while taking a bubble bath should not be underestimated :D

The camera is fine. I recommend you try to have a look at one in a shop or so or maybe a friend will get/has got one. I seriously find it a very nice device. No other device since I buy smartphones has astonished and wow'd me this much as this device. I always let go of a device rather quickly and I tend to buy good stuff. This one is a massive leap though from the last one. I'm really wow'd, thus I recommend go and play with one if you can.

Edit: nothing wrong with the Butterfly though, cool stuff as well. Just not eeehm... as "nice" or "classy" as this one.

Edit 2: my phone has had a bad day today. Maybe it didnt get enough sleep. It only gave me an 8659 today... :p
[Xperia Z Q&A, Help & Troubleshooting] crossmission:
it's UNDER 9000!!!

So it's under 9000!!! lol

Actually, yes, I am planning to get a first-hand opinion. I plan on holding on to the next device I buy, I don't really care for switching devices, imaging I kept my HD2 for almost 2 1/2 years just because I was satisfied with it, so a phone has been my longest relationship, double lol.

I'm not a power-hungry monster cause I don't really play games on the phone but I want it to be super smooth and a really crisp screen, loved the IPS display on my One X so the Butterfly is the logical way but on a nice winter day I came across the Xperia Z's leaked shots and specs, a few days later I saw the actual presentation videos and got interested, it's looks do get me going, it's probably the best looking phone out there now. The waterproofing is kinda important too as lately I keep seeing phones losing the fight against water and I don't want mine to be one of those, the Butterfly is more like splashproof than waterproof but it's good enough for me.

I guess that I can wait for a few weeks more and see if an update or a newer production line would solve any of the issues they have. I will probably end up unlocking cause I really do love to tinker with my toys so warranty is gonna go :poof: in the air and I want the device to last, the Butterfly has the benefit of having S-OFF now and I can flash to my heart's content and get away with it.

Anyway, time will tell, thanks though :)

6 <= Not for me, thankfully.

7 <= The device does get very hot but it's not too different from the overclocked SGS2 I used to have.

slow as in maybe 1-2min 1% charge increment

it does get really really hot for moments/periods, but then it cools down for my experience.

its like it wakes up from standby and then trying to pull everything at once and overload and heat... then it settles down.
