thanks for your answer some stuff you wrote make a lot of sense, also with no script don't forget to install adblock and do not track me. The phone i decided to buy ( Wiko cink peax) is unlocked, wich isn't really a option here : every phone are sold unlocked and with a "clean" android. i think i will create a new gmail account also. But the device isn't supported by cyanogen ...
i wanted to get a Nexus 4 but they are 120€ ~ 150$ more expensive in europe... and the S was overpriced on amazon or other online store for a 2 and a half year old phone
and also what's a PITA ?
