Operating Systems I also have some participated. Until recently, Android uses, but I did duly stinks because Google. At least I have to will not feel constantly spied on at Microsoft, which of course is complete nonsense. Even MS collects data as stupid ...... just not quite as flashy.
Switched from the Galaxy S4 Bin on the Nokia 630 to see if I can cope with it: Go mobile. The 630 was just good, and for 120 euros. Therefore, I said to myself, okay, fit, but it has to be something better. Then came the 730 just right.
Camera better
Fine resolution
Size good
Feel OK
expandable memory
Battery replaceable
Highly liquid running OS
All major apps available (WA, QD, and Micoach Runtastic)
For me important:
Dual Sim, private and work separately and always available ....
Navigation is perfect, whether with Here Drive or co ......
Battery life approx 2days in ordinary usage
Runtastic with BT pulse rate meter (adidas HMR)
What thrills me the Apps from Nokia and Microsoft, this software are very well programmed and often provide added value.
I highly recommend this part, the phone offers good performance at a reasonable price.
