I got a Galaxy II X. gt-s7560m It's gotten slower and slower every os update update, right now it take about 5 minutes to power up (boot to unlock). Then another 5 for the phone to stabilize and be able to do phone calls (or accept touch inputs to start apps) The battery runs out after 45 minutes. Even if the darn thing is powered off... or lasts for a 5 minute call I need to update the phone. I would say it's defective from os incompatibility (not enough power to run the os) and dead battery. 1)What phone can I get that is compatible with the network? 2) am I limited to what is listed on the koodo phone page? 3) Can I get another (any) phone and put in my sim card and go on as usual? 4) Can I trade in my phone with koodo for a better one? with the trade in as extra credit?
