Phonegate scandal

Hi all,

I received an official, state sanctioned e-mail this morning on my professional address regarding the PhoneGate scandal:

Looks like Sony smartphones are concerned by an excess of SAR (Specific Absorption Rate).

Are there any solutions, software-wise, to prevent further damage ?

Cheers, Sam

Got this from F-Secure.




After looking at the list, the only Sony Xperia affected has the Sony Xperia 5 which is not supported by Jolla. It also looks like the test of Xperia 5 has been redone and is in the limit.

I don’t think we need to worry.

Looks like classic tinfoilhattery. I’ll care when this has any second source at all.

It doesn’t exactly make it sound more believable if you have to point out all these things.


Hi :slight_smile:

Sorry I never meant to sound suspicious. I really received an e-mail this morning that seemed legit. Since Sony phones appear to be involved, I thought It’d be a good idea to share the news with the community. I usually don’t care much about 5G, Wi-Fi, microwaves and stuff. Maybe I got fooled by the flashy logos.

Cheers, Sam

Good to know the phone I daily drive harms me :))

AFAIU though, not only does SAR backoff not work on newer devices, but every Sony device starting from the kumano family (Xperia 1 and Xperia 5 from 2019) does not even support it anymore (no hook is used to adjust it after the switch to qcrild).

EDIT: this only applies to AOSP and SFOS (anything based on SODP).

If anybody here can conduct any SAR test, please let us know!

Reducing power to the modem kernel-side sounds like an option, but would very likely ruin the experience with range and signal issues.

I am not aware of any evidence that supports the notion that electromagnetic radiation in the GHz range at levels below what would cause actual burns have any detectable health effects. My impression is that people who are concerned about this have a poor understanding of what electromagnetic radiation is, and under what circumstances it becomes dangerous. They would do better to worry about staying out of the sunlight and other sources of ultraviolet electromagnetic radiation, which certainly can be quite dangerous.

This is because the energy quanta of the photon rises with the frequency (cf. the Planck relation), and at GHz frequencies it simply does not have enough energy to damage tissue, other than through heating (this is why you feel warm in the sunshine). Of course, if you crank up the frequency into the ultraviolet there is enough energy to damage the DNA in your skin, which can lead to skin cancer and/or damage the retina in your eyes, especially at high flux. Increasing the frequency still further gives the photon enough energy to strip electrons from atoms, to “ionise” them, and allows it to break chemical bonds, which is really quite bad indeed - this is why the dentist will leave the room while you’re having an X-ray done.

But the frequencies involved in wireless communication are many, many, orders of magnitude below this, and pose no danger to living organisms unless you’re exposed to hundreds of watts at very close range - in which case you’ll begin to feel uncomfortable long before any damage is done. Otherwise, the sun would already have killed you long before you got your first mobile phone.

Didn’t we all learn this in school anyway?
