Although there is nothing special about Nokia's touch screen technology, it is not a big problem. It feels good to use. As for durability, you should trust the Nokia brand! S605 software is not much, but it is enough. You can download it from Tianji.com or Saipan Chinese Forum. QQ can download the abridged version of mobile phone QQ2008Build060 (S60 5th edition), which can be found by Baidu search. It is suggested that the landlord register an account in Saipan Chinese smartphone forum to avoid finding suitable software to use.
