Kies Air is one of the best applications I've ever used. It is similar to accessing your phone from your PC through remote desktop or team viewer or log me in etc except that it is wireless!! Especially that my mother tongue language hasn't been enabled for writing on the current released version of Galaxy S II, so I can simply use my laptop to write SMS in whatever language I want, and send! And no doubt that using a PC keyboard is much easier than using any smart phone's keyboard.
But, there is one bad thing about it. Whenever I turn off the timeout (so kies will stay on as long as there is wi-fi), it doesn't really work and after sometime it just turns off automatically even if I'm uploading something (a big number of songs, say more than 40 at a time).
I thought of reinstalling the application, but I thought I would look for an easier solution before reinstalling.
Thank you in advance.
