[Xperia Z1 General] Minibull:
Overheating would be a very strange one though, I would expect issues with the glass splitting like with the XZ before the aluminium frame warping. The phones get hot, but not that hot. If it was getting hot to the point it may soften and warp, you would probably have cooked the battery and the CPU/GPU as well. Not to mention it could take time for it to warp.

I know someone who had an Xperia S, and they would hear it crack every so often when they would sit down, or bend their leg. No damage to it, but obviously something wasn't liking the pressure. Meanwhile I had an XS, never heard it make noises like that. But then I always have loose pockets, whereas my mates phone was wedged into his pocket, tight as.
[Xperia Z1 General] shteren:
net nessecerly... if the aluminum frame is made by chipping it can be made is a bad way causing internal forces inside the aluminum, these forces need not 500 degrees to alter it's shape, i'm not talking about the frame melting.

just a small temperature, 50-60 degrees is enough to give the frame the energy it takes to relive these internal forces and bend itself...

this is why i said manufacturing fault, because if some of the frames were made in one factory which did the chipping wrong and others in another which did it right it can explain why some devices bend and some don't. and it has nothing to do with external pressure...

if you want to google go for "strain tensor"
[Xperia Z1 General] Minibull:
When you say chipping, do you mean machining, or forging or something?

It could definitely be poor metallurgy. I'd also wonder about using cases, and whether they would trap more heat. OP here said his was in a gel case, I wonder if others whose phone bent had theirs in a case too. I also wonder if there are any that have warped in any other directions rather than just bending in half. You would think you might see the outer edge of the frame pulling away from the phone.
[Xperia Z1 General] shteren:
yeah i've ment machining, sorry for that, was translating from hebrew :P

and about the type of the band, it's quite obvious, it always bends around the power button and the usb port, thats EXCATLY where the frame is thinest because it has holes for the power button and the usb cover, thus making it the weakest part, and also the one more prone to internal pressure.

when trying to make lets say a 1 mm thing surface of aluminum using machining one has to be very carful,otherwise once removed from the maching the 1 mm sheet bends inwards due to inside pressure almost immidiatly and at room temperature.

it needs to be held straight and warmed again so the pressure is relived while it can't bend and then be cooled again.

it'sa timly costly proccess and thus i'm not surprised some factories are skipping it to save manufacturing costs...
[Xperia Z1 General] Aaron_035:
Sorry guys, as educational as that was, it doesnt help me. Mr Singapore, what do you suggest I do?
[Xperia Z1 General] shteren:
lol... dunno... once bent the area becomes weaker, so you'll be prone for more banding in the future even if you straighten it up...

so do your best to keep it intact.. i.e. don't straighten it by force, it will only make it weaker and might damage something, better leave it as is...
[Xperia Z1 General] Aaron_035:
Damn. That's too bad. :/

Edit:

Update, just came back from the Sony service center with a banana phone. Still pissed off this is not covered under warranty.

Quoting the lady at the counter :"Phone bending is a common occurrence with z1 in Singapore but unfortunately it is not covered under warranty."

I'll leave my z1 under a brick for the next couple of days. Perhaps I'll play games till its hot then leave it under the brick. This will probably be the last time this Z1 is not destroyed. Will update.
[Xperia Z1 General] drsoran2:
So putting a soft or hardcase cover around the phone increases the amount of heat which gets trapped and thus increases the temperature of the phone and may cause bending?

Cases kill Z1's?!
[Xperia Z1 General] Aaron_035:
I guess that's NOT the case.

I tried to bend the phone back by:

1. Putting a heavy book on it.

2. Putting a computer monitor and a book on it

3. Playing Asphalt 8 till it was hot and repeated step 2

4. Repeated Step 3 with an additional 6kg dumbbell.

So far, no luck, it keeps retaining the bent shape. Which leads me to question how did i bend it in the first place.
[Xperia Z1 General] BreakShadow:
Use a Psychic Pokemon to straighten it for you.
[Xperia Z1 General] aksmzk:
can we see some pics of this?
[Xperia Z1 General] shook187:
If it makes anyone feel good, LG is about to sell a bent phone and people will actually pay full retail for it
[Xperia Z1 General] ashouhdy:
Thats very unlucky i hope mine doesnt bend just sold my defected htc1 dont wanna face a defected banana z1 ... Thats sad
[Xperia Z1 General] Aaron_035:

My looks more or less like some of them.

It doesn't. Ha ha. It ruins a perfect phone.
[Xperia Z1 General] Moze666:
Omg, this is terrible, I don't know how you can bent it like that :D
[Xperia Z1 General] Aaron_035:
No idea. That's the sad part. I can't think of a way I bent it so I replicated some of the possibilities but nothing work. Also, I've sent an email to Sony. Hopefully they get back to me soon.
[Xperia Z1 General] dakunclear:
To debunk the heat argument: We can rule out heat and heat alone as the cause, because heat cannot permanently deform aluminium as long as it stays below melting point. Yes, below melting point things still deform, but they bounce back after the heat is removed, like the spring in your thermostat needle. Heating aluminium enough so that it is bendable by smaller forces than usual is also ruled out, because the amount of heat needed to do this is at the level of a blowtorch. The fact that the phone still works, and the undamaged plastic bits in the areas where the aluminium is bent show that this level of heat was not reached. So we can conclusively say that a force, not temperature, caused this deformation (forces can be external or internal).

The only source of large internal forces in a smartphone that I am aware of is from failed Lithium ion batteries expanding. The pictures supplied clearly show that this is not the case, since there is no evidence of the phone bulging in the area where the battery is installed.

This only leaves me to conclude that the most likely cause of the damage is from external forces, the sources of which I leave to your imagination.

That is what one of the guys who is an engineer wrote hope that solves some of the puzzle
[Xperia Z1 General] Aaron_035:
I get what you're saying, it looks like something I read on Xperia Blog, but I've honestly ran out of ideas on how I could have subjected it to a large enough force to bend it. Haven't so much as dropped the phone.
[Xperia Z1 General] shteren:
Aaron you've made me have nightmeres of my phone banding and being cut in half because i try to bend it back lol....

i really think this is caused due to bad manufacturing process of the aluminum frame... if you really didn't drop it or put any serious pressure on it... but you can't prove it to sony...

only if a lot of people come with the same issue... but so far i can only recall 3 or 4 cases of this happening...

the touch screen for instance effected thousands of devices so it was a clear sony error. but this idk...
[Xperia Z1 General] ashouhdy:
Maybe a faulty magnetic cable caused this. Due too heated up to bend but not melting as plastic phones
[Xperia Z1 General] jlssalgado:
Top notch I pass my hands.
[Xperia Z1 General] Aaron_035:
Hey that could be the thing. I've only used the magnetic charger so far.
[Xperia Z1 General] ashouhdy:
Plastic phones tends to burn .. But no aluminum will heat up to the point of getting softing. This happens with low quality chargers and cables. Specially when using phone during charging as it get heated up so high
[Xperia Z1 General] Aaron_035:
Interesting theory. But, I'm using the dk31 (I think its that number), that i bought from sony and using it with the plug that came with the phone.

Unless there's something very wrong, I don't think that's it.
[Xperia Z1 General] ashouhdy:
Heat it up ... Put the cable to charge and open data connection play some heavy games then unbend it on a hard laminated glass table.

---------- Post added at 04:57 PM ---------- Previous post was at 04:55 PM ----------
[Xperia Z1 General] Aaron_035:
Oh I did do that. Think it was number 3. Ha ha.
[Xperia Z1 General] ashouhdy:
press harder dont worry :D wont get any worse than this !
[Xperia Z1 General] shteren:
yes it will! the motherboard may crack! don't tempt him to do ireversible things! for now his phone works...
[Xperia Z1 General] ashouhdy:
then how didnt it crack in the first time ? on a plain glass table it will not bend further than the usual or factory made.
[Xperia Z1 General] Aaron_035:
Right. Point taken. I'll just wait for Sony to get back to my email.
[Xperia Z1 General] Aaron_035:
20/2/14 - Day 28 - Finally, after a lot of emails between me and Sony and even longer waiting time for emails, Sony has finally got back to me.

https://www.dropbox.com/s/h3v7rln8wuahxm0/Capture.JPG

First of all, I'm slightly disappointed with the amazing speed that Sony dealt with the problem but finally, at least they are willing to make the repairs under their "good-will".

I found it interesting that Sony would fix it under "good-will" but who am I to complain? I just saved SGD405.90.

Anyway I attached the email they sent me. Perhaps it'll help someone whose Z1 is also bent due to "supernatural causes" to get some assistance in the matter.

Can' t wait to get my Z1 back in 3 to 5 working days.

[MENTION=4640550]Aaron_035[/MENTION]

sad to c tat your phone bend!

u said tat your phone put in your pocket. is it the front or the back pocket?

if is the back pocket, than the chances of getting it bend is quite easily, as z1 is quite a thin phone.
[Xperia Z1 General] Aaron_035:
Well. I put it in my front pocket. But I don't think it was me putting in my pocket that bent it. Cause after putting it under a large weight, it didn't bend back, leading me to assume it wasn't in the pocket.

However I won't be putting it in my pocket anymore. To be sure.
[Xperia Z1 General] chunlianghere:
i was wondering is your pants a jeans?

some pants front pocket hav a very shallow pocket. so if squat down, will kind of stressing it.

previous phone i hav a xperia v, same as u, no need to worry much in pocket. now, sometimes hav to worry how your phone will "feel" in the pocket. haha.

about the heat, mostly at the upper part of the phone.

looking at the internal, http://blog.gsmarena.com/a/showpic.php?sImg=/13/09/xperia-z1-teardown/gsmarena_005.jpg, i guess the bend part should be around microsim/usb port/microsd if the heat tat cause it.

since its in the center, mayb the battery is trying to do some stretching? :eek:

mayb can ask service center to do a check on the battery.
[Xperia Z1 General] Aaron_035:
Yes. I'm wearing jeans most of the time, uniform of an engineering student. Being 1.6m means that my pockets are relatively shallow which have led to my Z1 being stressed. That's why I don't intend to do that now.

Mine bent in between the SD card slot and USB port.

Good idea. I'll ask them when I get it back.

My suggestion to any Z1 user is to never put it in any tight fitting clothes. Hell, personally, I'll never carry it in any pockets ever again. It shall stay in my back pack, beside my laptop.
[Xperia Z1 General] Aaron_035:
Update:

Finally, I've got back my Z1. When I got it back from Sony, I was in a rush, so I didn't look at it really closely. So the next day when I finally got a chance to look at it, I realized the phone is still bent in the exact same fashion albeit to a slighter extent.

What I assume happened was they replaced some parts but left some parts which were bent unchanged, resulting in the phone being like that. I'll upload the invoice they gave me with all the parts they replaced.

I wrote an email to Sony this morning. Hopefully I don't have to wait 2 weeks and send in another email to get a reply.
[Xperia Z1 General] Bagel-Ralph:
Aaron, right after using your phone, did you happen to put it in cold tap water? That could have warped the metal.I think that is what happened to my phone.

I believe that my phone was bent because when I was finished on Reddit (which I don't finish on Reddit often) my phone was a little warm and I thought, I should go rinse it out after a long day at school. So, I rinsed my phone under cold tap water. The next day, I noticed a slight curve in my phone. I got really worried and didn't tell anyone because I didn't want my friends to think I treated my phone like sh!t.

I called Sony Xperia support and they seemed to help me, I gave them my info and they said I would get an email with mailing information so I could send my phone in to get looked at and possibly fixed. About 5mins later, he called back and said, "There was an error, since your from Canada, you have to call the Canadian one." He gave me a phone number to Mazak Canada... As far as I know, it has nothing to do with Sony...

I hope everyone's problems will be resolved at a cheap/no price.

-Nick
[Xperia Z1 General] Aaron_035:
Hey, Nick, first of all, wow. Can't believe anyone found this old thread.

Second, now that I think about it that could be a possible reason. I think I did that when my phone gets hot.

Since I got back my Z1, I've just left it in my Roxfit case and trained myself not to er... Measure its curvature in case it comes back. Trying to prevent my OCD from kicking in and bugging me for the rest of my life since Sony performed the prior repairs under their "goodwill" and voided my warranty in the progress.
[Xperia Z1 General] Bagel-Ralph:
I think I'm going to end up buying the HTC One m8, Nexus 5, or the Galaxy S5. Prior to buying my Z1, I had a Nexus 4 and really enjoyed it until KitKat came out, that pretty much messed up my phone and I bought my dream phone, well, I thought it was my dream phone... Which phone do you recommend? It doesn't have to be from that list.

Also, I never used the magnetic charger, so that is out of the question. Judging that some people's phone bent and others didn't, I think there was a bad batch of Z1's and we both got one in our pockets. Sony used to be my favourite brand for electronics but, the fact that they refuse to repair/replace our phone's for free because it isn't covered under the factory warranty.

Thanks

I wouldn't suggest any Samsung phones unless you want to go with the note series....and I would wait to see if the rumor about HTC releasing a plastic much more affordable version with the same specs is true
[Xperia Z1 General] mylaw:
Hi!

First of all I want to "say" that I came from Samsung galaxy s4.

I chose Sony xperia z1 because the camera and xreality.

At the first-second day I didn't love the phone . after the update the camera was better and the speed was great but... I'm one who love to experience with new roms so because of that I'm trying very new rom that gets out. The only problem there is not so many roms or devs here. It almost dead. I hate Sony for creating experia z2 so fast, our phone the xperia z1 should to get the best support , but it OK because we have here devs to they not much but it OK.

P.s

Hope that someone will release mod for better quality sound.

I know that my English is not so well but I won't will sort for that
[Xperia Z1 General] Aaron_035:
FYI

I just got a Note 3 and have been trying to use it but I keep returning to my Z1.

Reasons include:

Not used to the ergonomics

Too freaking colourful UI

Too many gimmicky features for me, perhaps you'd like it.

and most importantly, I NEARLY dived into a pool with it XD
[Xperia Z1 General] Bagel-Ralph:
lol, I would also forget that I don't have a water proof phone any more, if I got a new phone, and would jump in a pool also. I wouldn't mind the colourful UI on the Note 3. All that matters to me, is the amount of ram, how fast the processor is, and the size of the battery. I know for a fact, I'm probably never EVER going to get a Sony phone again, and I love Sony. I want Sony everything, but if I knew what would happen to the Xperia Z1, I wouldn't have bought it, as you wouldn't either because who wants a defective phone? It's going to take a lot of effort to sell it at a reasonable price. Are you going to sell your phone? I don't think I will any time soon because well, despite the bend in the phone, I still love it.

Thanks

Luckily or unluckily for you the Z line xperias are not the only waterproof high end handsets anymore( S5 )
[Xperia Z1 General] Aaron_035:
Hopefully this won't turn in to a fanwar.

I would still get a Sony device in the future. I personally like their design better and, most of the time, the feeling of exclusivity as not many people use Sony phone.

Its up to you to to get a Samsung device. Its awesome if you enjoy it, but I'll stay here with my Z1. Sure it has it flaws but at the end of the day, I enjoy it, so I don't see why I would sell my Z1. I would probably get a Z2 Compact or something once my contract ends. The Z1 is too darn big.

P.S. If i recalled right, negrobembon, the S5 was marketed as "splash-proof" not waterproof. Am I right?

Also, Nick, in my humble opinion, since the current generation of devices got released, Z1, S4, Z2, S5, the amount of ram, how fast the processor is, and the size of the battery doesn't really matter any more. The lag in most current flagships are negligable and the battery life are more or less the same, give or take.

I'm happy for you that you still love your Z1 and hope that if you get a better alternative, you'd enjoy it.

Aaron
[Xperia Z1 General] mzharmony:
I really didn't know about these issue, does anyone think the same thing will happen with the Z2? Or has Sony rectified this by adding plastic?
[Xperia Z1 General] Bagel-Ralph:
I definitely won't be the cause of this "fanwar" and I hope it doesn't happen here.

I guess your right about the size and speed of a cell phone don't matter any more, It's all about the users preference. I'm going to stick with my Z1 as long as it lasts. I don't really have the money to get an alternative phone quite yet, but I will get a new one once my Z1 is gone. I also love the uniqueness of the Sony Smartphones because like you said, not very many people have them.

Thanks for your feedback and everything else Aaron, I appreciate it.

After configure timelapse on CM11 nightly 20140120 camera do not open anymore, it just say "Camera has Stopped" and closes, have tried to reboot but no lucky. What i could do?
[Upgrading, Modifying and Unlocking] mda2user:
I bought a MDA2 off ebay and it said in the ad it had WM2005 on it, i figured it was a typo so i went ahead and bought it. ANyway i got the MDA and it has WM2005! The main reason i bought it was to run tomtom navigator 5, now i managed to install it but the backlight refuses to work. I just want to know where i can download the original rom from as i dont want WM2005 because its not designed for the phone....

Tried to be clever and i downloaded a rom from the o2 website and tried to reflash the phone with that rom, it came up with some error message and it totally crapped out my mda. My mda is now on a dark screen that says serial v1.02 and when i put it in the cradle it changes to USB v1.02. Tried running different roms but its not accepting any. Activesync is not picking the device up anymore...

can anyone help?
[Upgrading, Modifying and Unlocking] Midget_1990:
OK so you want an official rom?

1) What is the HTC anme for an MDA2?

2) What carrier are you currently on?
[Upgrading, Modifying and Unlocking] mda2user:
i dont mind what rom it is...as long as it works. Carrier? I am on the o2 network if that helps. HTC anme? I have no idea what that means. If you could tell me how i can get this info for you i will :)
[Upgrading, Modifying and Unlocking] Midget_1990:
oh crap, spelling mistake on my end, i meant HTC name :P

also i forgot, what country are you using the phone in?
[Upgrading, Modifying and Unlocking] mda2user:
Well its a T-Mobile MDA (what it says on the device itself but i beleive its the same as an XDA2). I am in England and i am on the o2 network.

looks exactly like this
[Upgrading, Modifying and Unlocking] Midget_1990:
Do you mind having a non-official rom?
[Upgrading, Modifying and Unlocking] mda2user:
I dont mind at all, anything that makes it work.
[Upgrading, Modifying and Unlocking] Midget_1990:
ok, try hard resetting your phone, it should boot back into WM5, you will then need to download a wm2003 rom (check the WIKI for options and choose one) and install that (again the wiki should hold all the information you need)

( i didnt tell you this in the first place because i was looking to find an official o2 uk rom, however you need to give them your imei, and o2 phone number to do that, somthing i dont have :P )
[Upgrading, Modifying and Unlocking] mda2user:
Ok firstly, hard reset (holding power whilst placing stylus in reset hole) is the first thing i tried, its not having non of it. Just shows USB v1.02. I was able to download the rom from the o2 website by giving my IMEI of this tmobile phone (how? i dont know). There was an error durin the installation which caused my mda to crap out. Its not going past that screen at all.
[Upgrading, Modifying and Unlocking] Midget_1990:
during the install? as in while it was actually copying the rom?
[Upgrading, Modifying and Unlocking] mda2user:
yup m8, as it was getting transferred over
[Upgrading, Modifying and Unlocking] Midget_1990:
k, this hapened to me earlier todday as it happens (i was testing ivans new rom)

the reason it was caused is that the operator ID is set wrong, to fix this follow these instructions:

go to "c:\documents and settings\your_username\local settings\temp" and delete everything there.

run the origional o2 upgrade DONT PRESS NEXT OR ANYTHING, JUST START IT.

go back to "c:\documents and settings\your_username\local settings\temp"

there should be a new folder created, copy this to a tempory location.

extract the contents of this attached zip file into that copied directory.

double click on setoperator.bat

run the HimaUpgradeUt.exe in that folder to put your phone back to the wm2003 os.

if this doesn't work then i'm stumped, sorry
