Xperia Z Disadvantage and tips Must Read

[zohaib0001]

Hello to all
Today I am going to tell you about a very big disadvantage of Xperia Z, may be some of you already experience it

Before talking about disadvantage you need to know about some Information
As we all know Xperia z is water and dust proof, its means it is an air tight handset. We also know that all the processors and electric chips create heat while they are in use, and the heat from Xperia Z Board remain inside of Xperia Z that’s why we feel it’s back cover heated up when using it.
Heating up device is also because of the Rom software that we are using; right now Sony is not able to give us a perfect Rom for Xperia Z, which will not heat up our device

Second thing to know is about Xperia Z Disassembly
The Xperia Z back cover is not tight up with any kind to screws. It is assembled with some kind to chemical seal material, this seal is lose it up when it is heated
Here is a video for that please take a look 1) Link Daily motion ---- 2) Link you tube

The Disadvantage of Xperia Z
Xperia Z heat up so much during use and it back cover reached up to 38 to 42 Degree temperature
If you are live in country where normal environment temperature is 35 to 45 then both these temperature together make heating up device more, that will be effect on the back cover seal. The life of the seal will also be affected with it
Here are some people who experience already that their device back cover is starting losing up
Here is the link for that please takes a look

Once this seal is losing up its mean our device is not water & dust proof now, and if you put your phone into water in this condition then you can hard brick it

Tips for avoid that
1) Do not use your phone up to that level where your device heated up so much until unless Sony improves the Rom, and heating up problem is solved
2) You can also use custom Rom from different developers that do not make device heat up so much
3) Do not put your phone into water because you don’t know how much seal is losing up from back cover, It’s better to check the seal from a mobile service shop. Because if once water get inside your device then your Xperia Z will be hard brick
4) If phone go overheating just open the ports like headphone,usb and etc.It help to air circulation in phone. this tip is provided by propov

About
I really don’t know why sony did not apply screw in the back cover of Xperia Z, this device is expensive, majority of people buy it after a lot of savings and in the end what we found a design disadvantage or fault
I am really wishing that sony will not do this thing with Xperia i1 Honami

During the heating,the overheat control comes into play..it lowers the cpu clock speed and cools the device..btw even during the case of extreme heating,the sealant won't wear off..it may melt if that's what u think,but it's waterproofing capabilities won't be gone...I've dipped my phone many times in water when I first bought the phone cuz the os wasn't that good then and was causing overheating constantly and it was working perfectly, no seepage in my phone and now it's a lot better after updating to 4.2.2 and my phone doesn't cross the 38C mark most of the time..

My Xperia Z's never managed to get past 35°.
Probably just because of the weather over here.

in you tube there are so many videos of heating test you can search and take a look

it shows 41 after playing games

if it will not effect the seal then what you think on this http://forum.xda-developers.com/showthread.php?t=2304680

It may be some manufacturing defect bro..I've only said what I've been experiencing since I bought my XZ..I said the adhesive MIGHT melt during extreme heating but would cool down again..we have to be sensible enough not to try pulling out the cover at that time.. Other than that it is really a fine beauty

The reason why the XZ doesn't use screws is because screws are simply not tight enough to ensure a waterproof seal... thats why adhesive is used since it covers all entrance points into the phone

 

[DoubleYouPee]

My XZL gets hot too....

In a way, what stopped Sony to use adhesive layer + screw and seal on screw to ensure 120% waterproof.....
Apparently lack of testing in extreme conditions..... Would not expect it from flagship development...
Well, I just hope that this "lifted back glass" issue is just attributed to very small scale of defected batch and the rest millions are not affected

This thread forced me to look at my device, and I'm a bit shocked to discover that after just 2 month of VERY GENTLE use, the pearl-color paint on the sides (I have a white XZ)
got a lot of chips and started to peal off on the corners..... WTF

I have the same problem with my Z, the back glass has lifted where the camera.

But I went to a swimming pool last weekend, and took some underwater pics, and till now no problem.

Please tell me you do actually realise the heat guns in those videos you linked provide a lot more heat than your phone will reach during regular (or even excessive) use. Those guns probably provide around 300 degrees (yes, celsius) hot air, if not more (in fact, probably more). The phone has sensors which both clock down the CPU (to avoid heat) and eventually actually kill power altogether if the temperature is too high for an extended period (providing the OS is running normally and isn't locked up, if that is the case then you should go ahead and hold power and volume down for a few seconds until the screen goes blank).

Oh and climates where the temperature regularly gets to 35-42 degrees are not going to substantially lower the life expectancy of the seals either. Perhaps something like a few weeks in total at most, but then again it doesn't really work that way. Yes, if you leave it in the sun all day on a hot and windless day you might have a problem, but then again that really applies to all countries.

Stop scaring people into thinking their phone is about to fall apart if they play games for too long, that is not going to happen!

People, your phone is waterproof, but don't be ridiculous and go and use water to cool it or something like that, and don't be silly and leave it in a pool all day just because the box says it is waterproof. Instead, think of it as a comfort to not have to worry about your phone when it is raining or if you accidentally spill something on or around it.

If phone go overheating just open the ports like headphone,usb and etc.It help to air circulation in phone.
Sory for my English!

Highly doubtful, and don't blow into any of them either! Just put the phone down for a bit instead, perhaps onto something with good thermal conductivity like a piece of metal or something massive and cool like marble. Maybe turn off some graphics or processor heavy apps.

Modern day adhesives work way better then screws. they save space, weight and costs. They are used everywhere from cars to building construction.

Are they always perfect? well that depends on application and testing. Even Ferrari had some 458's catching on fire due to the adhesives overheating.

Lol..but the phone ain't gonna catch fire in any case whatsoever and yup, adhesives these days are rapidly replacing screws and what I guess is the bulging of the back panel is due to some manufacturing defect,not due to heating of the adhesive..well maybe,unless they had pulled the back panel during that "extreme hot" window of 5 mins..it concludes xz rocks..

you take me wrong

i am not here to provide any negativity about xperia z, or i am not scaring the people
i am just sharing information, and of course i am also want to buy xperia z and i will get it within this week so i am not against xperia z

i am just sharing information, if you think that the life of seal is not going to affect then it is your thought and i am sharing mine on the bases of reality with videos

Thanks for your tip

Since I also play games(RR3 and DH4) on my Z, whenever it gets hot, I just place it on the floor for 10 seconds. It cools down to a warmer temperature, enough to continue playing.

Yeah,.people are definitely free to do whatever to their phones.

Anyway, the phone is designed to be waterproof with the use of seals to keep water out. The electronic components inside are certainly not waterproof. If you see the back lifting, it means gaps (maybe very small) are formed somewhere underneath the back. It's similar to opening the phone up for repair.

It's just common sense that if you have a gap, water can go inside.
