Still on the N900, quite worried since this is my last working one. Since 2009 I encountered the following issues:
1x cellular problem / modem not working
1x digitizer
1x screen
1x GPS
1x keyboard
1x speaker
1x cellular antenna
1x USB connector
Scavenged them many times for building a working one, I currently have three retired. Last time a couple of days ago, it took me less than 15 minutes to replace the mainboard due to a non working keyboard.
My path had been:
N900
Lumia 920 (Winphone)
XperiaX with Sailfish
N900
If the Pyra makes it on time, next one will be a IP67 dumbphone. Otherwise... I really don't know!!
