Compared to the Android or Apple devices or I like the user interface very well -they acts modern and is designed excellently. The 735 provides just about everything a smartphone should have the luxury class. The build quality is top notch. The housing fits perfectly and feels really good at (not plastic Feelung). The screen is a scratch resistant OLED display, which is very easy to clean (much better than the 630). Suffice only a towel. The applications run smoothly, the touch screen responds very well. I also like that the battery can be replaced. It has become in so many manufacturers to habit, to build in the battery pack firmly. It also has the advantage that you can change the case, if it should be scratched or times you want to have a different color. The size of the device I find perfectly - not too big, not too small.
The differences between the 730 and the 735:
- Dual-Sim only at 730
- LTE only in 735
- Charging the battery without plug by placing it on Nokia Wireless Charging Plate only at 735
If you do not need 2 SIM cards, I absolutely recommend to 735. I would buy no longer a smartphone without LTE and wireless charging is also a plus!
Who does not need a maximum compatible smartphone, obtained by the 730/735 a contemporary smartphone at a really good price. Who camera and display are not so important, can also calm to the 635 attack - which is a real bargain at about 130 euros - the same processor - less screen resolution and camera without flash - but a very good smartphone with LTE! Wrongly Windows smartphone lead a shadowy existence. After several years of drought Nokia builds top phones again. A refreshing alternative to Android or OIS!
Addendum: A few days ago I have an iPhone 6 as a company phone. Unfortunately, they wanted to make me not a Nokia available. I had the choice, I'd take the 735. The iPhone can not do anything better - on the contrary, the 735 has in my opinion the better screen, memory expansion via an SD card and it is not always ties me to ITunes. Compared to the alleged Mercedes among the smartphones one would forgive 735 6 star - if I already see the altbackende surface of IOS, I want back my Nokia.
