Positives:
+ The battery life. In normal use, I plug it twice a week in the docking station. But I do not even open the cover of the micro-USB.
+ The camera is very good for smartphone standards. Very convenient is also the release button, with which the phone from standby goes straight into the camera app and then also serves as a trigger.
+ It is waterproof. I still have no long-term experience, but the sweat while biking it survived so far (2 tours in Tenerife).
+ The GPS reception is very good. Even in an airplane it worked if you held it near the window.
+ Faster processor. No stuttering or delays.
Neutral:
° The voice quality is normal, speakerphone works well.
° The display is bright and easy.
Negatives:
- The weight of 137 grams is ok for me, some find it difficult.
Otherwise:
I use it with silicone case and screen protector. This makes it very handy and well protected, but can still operate very well. The button on the side (A, volume and camera shutter) are the silicone shell more convenient to operate than without. The docking station (not supplied, costs about 12 euros) loads the Phone via waterproof connections.
I bought the device the same again for my wife, she's thrilled.
