I always thought all Android phones can use USB peripherals on the micro USB port. At least my very first smartphone (Samsung Galaxy S) from 2010 was capable of that. Is that not the case for Fairphone? All you need(ed back then) is an adapter from micro USB to USB-A.
Edit: The adapter is called USB OTG (on-the-go). Apparently not all phones are compatible. Here is an incomplete list of compatible devices. Stackoverflow has instructions on how to test whether it works and how to get it working.
You are right, for OTG you need
So it requires a bit of hacking, but technically possible.
You can run āUSB host diagnosticsā from play store to check your phone capabilities. Iāll try this when I get my FP2 
edit : sorry i didnāt see your edit and the links you posted. they say pretty much the same, sorry for the repeat
Hi people
Iām not sure, but I think that probably many will want the FP only with a good rear camera - it is useful for many, including many activists, and although thatās not the major point of this phone, it makes it much more attractive, given the high price
Is there any optional module like that? even if not from FP shop itself
Thanks!
This is an user forum. Search the forum and you will find hints that it could be possible to do so. But keep in mind: The FP company needs money and selling modules is a good way to do so. So if too many people update their phones like that, it will hurt the project in the long run. Just wait a tiny bit longer for an update, Iām sure there will be one some day.
Oh, but what about a module from the company itself? I didnāt mean to go behind or something - Iām just thinking this is a serious selling point and also Iām not sure that such a module should be that expensive
I think (Iām just a FP1 user) that there will be an upgrade module soon. But look, the phone just came out, so just give them some time, most of the FP2s are not even shipped yet. 
For everything else, just have a look at the forum, the FP2 specs, the pictures of the inside of the modules and at the code released for the FP2 and you can see that there is room for such an upgrade ā¦ as one can expect from a phone with modules 
You know, I just feel bad as it is for buying all the consumer stuff I do. Currently I have some chinese $80 smartphone, so a $500-$600 phone is not a thing Iād usually do, and if Iām going for this phone, at least I want a nice camera or an option for such a thing
Thanks!
Currently there is no such option (reviews and users say the camera is usable but does not compare to cameras in high end smartphones like an iPhone). If this is important to you, you should probably hold back and not buy a Fairphone yet. I personally doubt that Fairphone will offer upgrade modules in the short term. But Iām just guessing.
Yeah I also have the feeling they are really busy atm with things further above on their todo list. Also I never heard them say they plan to make updated modules themselves at allā¦
For the people looking for NFC: in the Netherlands some providers are already handing out new SIM cards with an NFC chip on it for wireless payment and public transport. So that would eliminate the need to put NFC on the FP2 itself.
For the new modules: think FP would do wise, in my opinion, first to enter the US & Canadian market and see if they can double the amount of FP2ās sold. That will free up more money to invest in future developments on the technical side and on getting the production and minerals for the phones even more fair.
On the technical side: I hope the FP2 design is future proof enough for an updated version with better cameraās, better processor, USB 3.1 etc but that those modules are still compatible with the first version of the FP2. Than users can decide if they want an update (i.e. a better camera) or just stick to their existing FP2. And when something brakes they can replace it with an upgraded part. Advantage for FP: they can reuse the design and save development costs and the consumer will be re-assured that spare parts will be available much longer. And users send the replaced parts back to FP so they can be in stock for repairs or recycled when broken.
Doesnāt FP want to say something clear about it?
Also, about entering the CA/US market - Iām pretty sure that for $600 youād need some nice things like a little better camera that you can find in a $200 smartphone today (Moto G 3rd gen / others)
Actually I have heard Olivier (Fairphone OTC) mention the possibility at Fridayās community event.
When talking about modularity of Fairphone 2, he said that it also enables them to provide replacement modules for a longer time because the parts donāt necessarily need to be the exact same version. He mentioned the problem for other phones that components (say, a camera) gets an update every couple of years and the manufacturer stops selling the original component.
Olivier said that with Fairphone 2 this is less of a problem because the modularity makes it easier to include updated components where in ānormalā phones these updates might cause problems.
However, this was highly theoretical and sounded more like a contingency plan to make modules longer available but not include better versions right away. So this basically emphasizes @paulakreuzerās point that itās unlikely for Fairphone to sell upgrade modules at the moment.
That sounds like a very reasonable plan. I hope Fairphone is reading your post 
About NFC : No, no, no ! yeah, with the sim card, we can pay by NFC/take the bus , but you are forgetting the fun part of NFC ! : with an app like Tasker or Automata and some cheap NFC tag , you can make automatized actions, like turning on wifi, making the phone silent, forcing sync, open an app,etc, itās a gadget, but itās SOOOOOO useful daily !
Personnaly :
As I understand, other apps could use the NFC chip on the SIM as well. So perhaps it is still possible to use the same NFC chip for the actions you want. The only problem I read in the little print is that not all smartphones will be able to use the NFC on the SIM card.
As soon as I have my FP2 I will test this. My printer supports NFC and I have to order a new SIM from KPN (which is free for post paid) and that will have NFC.
I have an nfc enabeled SIM card, but i canāt use it since my phone is not nfc, as i understood, the chip inside the SIM doesnāt contain an antenna, itās just a bridge between the phone (wich have nfc) and the payment service
Not sure at all eitherā¦
[quote]The ability to use your SIM as an ATM card is dependent on a NFC-enabled smartphone (using Android 4.1. or higher)

Translated freely from this Austrian source
Why do they call this a āBankomatkarteā (āATM cardā) when you canāt use this at an ATM?
And I think this is broken by design because it is not working on rooted devices. (That means that the security of a smartphone is overestimated by them. All Android devices except the Google Nexus ones 
have open security holes now, so you canāt even trust your FP1/FP2.)
You can pay at wireless NFC terminals in supermarkets for example. I do use this. But with my NFC-enabled ATM card, not with my ATM-enabled NFC-phone. 
I trust this little piece of plastic more than my phone to be secure.
For financial transactions and the like you need two things: the NFC transmitter/receiver and a secure element. Usually, the secure element is embedded on a SIM in current banking setups (unless Iām very much mistaken). The communications are handled by the hardware on the phone. Thereās an explanation of the secure element part here.
If the latest update to my local bankās ATMs is anything to go by, youāll soon be able to use it at the ATM.
[sarcasm] Actually, if they keep adding features at this rate, theyāll probably soon start dispensing free coffee while you wait for your cash. [/sarcasm]
It has already been said elsewhere, but it seemed me interesting to add it here : an improvment would be to being able to know in which position the phone is in our hand when we pull it out of a pocket.
Currently, the FP2 is too symetric and Iām always seeking the unlock button.
A cover with striations on on half (lock button upper half or APN bottom half) should achieve this.
Or, having a soft and a rugged material in those bicolor 3D printed covers : Fairphone 2 3D printed casings available
