Unlocking the Sony Xperia Z3 bootloader degrades camera

03 October, 2014
Low-light performance and noise reduction algorithms are affected after bootloader unlock.

To make a good summary, please read reviewof the following:
Samsung galaxy alpha
IPhone 6
Sony xperia z3 compact

Z3 compact rules!

End of discussion.

Btw, alpha and IP6 is still catching up with z1compact.

G3 does not count coz it belongs to weak battery category.

They said Z2 has great camera as well, but it was disappointed.

This is why you wait until their is a root solution to backup your TA partition before bootloader unlocking any Sony device.

In two or three year's time when OEM support ends you can flash a custom ROM, which by that time will probably have better camera processing algorithms anyway.

Please explain how rooting a phone can cause a hardware failure? Unless the flash goes wrong, of course, but that can even happen with a stock ROM. I have seen it happen with a stock ROM update. So using that logic I cannot have administrator access or BIOS access to my home PC because I might damage it? Is that what you are seriously proposing?

I bought a Z2 and got the code from Sony to unlock the bootloaderm. I never unlocked it because the phone was new and Sony warned that unlocking the boot loader invalidated the warranty.

The Z2 is only a few months old and works great with stock software. However, that software is already old. It's 4.4.2. Though Sony's software is good and not too bloated, I'd rather be running stock Android.

What Sony should do is offer Stock ASOP ROMs for each high end phone they sell so the buyer can run the latest stock android or Sony's version of Android. However, the Stock Android software must utilize Sony's reality X engine and the Camera software and hav the FM radio.

I bought a Sony Z Ultra GPE and it did not have the FM radio and images on the screen did not look all that good so I returned it.

Sony's hardware is fantastic except for the lack of Qi charging and the placement of buttons which don't work well with Car mounts. They also need to add more internal memory and allow apps to be saved to the external SD card.

If Sony would do this, they would sell many more phones. They should focus on the high end and leave the cheap phines to someone else.

If the camera fails on custom ROM, you never know if it didn't for example provide too high voltage, or leave the shutter open.

That's a common thing, go learn a bit.

Fefo, 03 Oct 2014there are several Knox-friendly roots out there...For the Samsung Galaxy Note 3 (N9005 international version) running stock Android Kit Kat 4.4.2? Please provide an appropriate link. I would love to root it and get the Simplistic Framework working on it but not if the warranty will be invalidated permanently as a result of the rooting process tripping Knox. Last I checked, about 4 weeks ago, it cannot even be rooted without tripping Knox. Let alone anything else.

AnonD-278385, 03 Oct 2014YES, This has been an issue for a while now with some Sony ... moreDo you confirm that happened while running the official ROM or is it with any other 3rd-party ROM?

The key aspect here is the Bionz image processor that this phones feature (from Z1 up) which cannot (yet) be used outside the official Sony ROM.

In Z3 we now know (from Sony) that Bionz requires some DRM key that will be lost when unlocking the bootloader, now the question that remains is if previous Xperias have always operated like this or if this is something newly introduced in this models (being the "issues" with Z1 and Z2 just lack of drivers/knowledge of how to operate Bionz).

That is now necessarily bad... It might be a crude version of raw output if compression algorithms are affected!

Meaning should we get the phone or not!!?

farbod, 03 Oct 2014Does it affect on Z2 too???YES, This has been an issue for a while now with some Sony devices. I had a Z2 prior to my OnePlus and i can confirm that when you unlock the bootloader the amount of noise increases a lot. Image quality is also degraded.

  • AnonD-215925

i bet sony did it specially :D:D unlocking bootloader don`t have such an issue on a phone, it MAY degrade battery life but Camera its different part :D :D maybe after unlocking bootloader camera uses other, degraded libraries? XDA to know :D :D

  • AnonD-196068

At least Sony users won't have Knox permanently invalidating the hardware warraty so that Samsung can get out of fixing hardware under warranty because of unrelated software issues. Knox! The definiton of Malware. Something that I did not ask for, that i do not want, that I cannot get rid of, that prevents me doing things I wish to on a device I have paid for unelss I am willing to invalidate the warranty permanently.

If the Z3/Z3c uses the TA partition to store the DRM keys (like all other Xperia devices), then Backup TA may be a solution:

Nevertheless I've just explained why anyone would want to do it before those arbitrary 2 years, just read my comment below.
