I've seen too many sites with lots of phtotransistors which is why i am confused, the photos are slightly blurry but you should be able to make it out. this photo-transistor came from an old Sony TV and has a casing and it's dimensions are h: 12mm w: 10mm and d; 6mm with the casing.Unless it has some part number markings on it it will be hard to say whet it is. If you are familiar with phototransistors and their operation you can sit down with it and a ohmeter and start probing it. A Google of phototransistor will bring up literally hundreds of images and pinouts. Might be a good start. Even if you could post a few images it might help.

I have a 3-Pin Phototransistor from an old Sony TV, but i don't know the pinout and what pins to use to make it act as a photodiode...
It also picks up infra red from phone signals! I just discovered it as i connected The IR reciever and the output spiked when i didn't press the remote and i realised that it does pick up a few Phone signals...
Back in those days before bluetooth and wifi phones had IrDA for connecting to other phonesInfra red from phone signals?
Seems IR may be making a comeback for controlling entertainment centres etc.Infra red from phone signals?
Maybe but its the first I have hard of it.Seems IR may be making a comeback for controlling entertainment centres etc.

Some older phones had IrDA ports for data transfer, but this got surpassed by Bluetooth.
Looks like some engineers added the hardware back in, to provide yet another gimmick for sales and marketing.
HTC One and Galaxy S4 aren't relatively old phones.Maybe but its the first I have hard of it.
My 1st guess would be he has a vary old phone.
And they have IrDA?HTC One and Galaxy S4 aren't relatively old phones.

Thanks for the link, who would have thought.Check the link Andy, seems that some things not-Apple are making a comeback.
