Have in October 2014, these Nokia Lumia 735 bought and left me with the review deliberately time. Problem: I have been long engaged in the acquisition of data from my (unfortunately "died") Nokia Communicator 9300. After finally had worked well with the contacts (via CSV file and Outlook), but I had a lot of unexplained noticed "disadvantages". Although essentially concerns "only" the system WP8.1, but that belongs to indivisible. Examples: Calendar may only daily, weekly, monthly or yearly recurring appointments (9300 was also 8 weeks in 3rd Fri of the month, ...) Excel is severely restricted: no "new folder", a new table (goes existing filter) in folder, select multiple cells / copy does not work, copy a cell / paste goes, but salaries are not adjusted! (All things that was not a problem in 9300) - ie: not really usable !!! - So much has to prepare the PC, then the Lumia only type of data! Word: not required OneNote: no new notebook possible (or not found), the biggest drawback: ONLY (automatic) save in Onedrive (not local), thus unencrypted somewhere ... Then I noticed that the device sometimes restarts every few days. After the Note (Windows typical) "the SD card needs to be checked, any loss of data." Was fortunately never, but when it is 3 x restarted in a day, I have studied it: On the web have been found, I then installed the device is reset, taken without an SD card into service and no additional app. 1 day later again. However, you go without an SD card "and not only restarts. Dealer says sending in completely, we will send it in a workshop - possibly gehts about Nokia faster. Nokia Support suspected hardware failure should I send the device without accessories (without SD, SIM, battery). Approximately One week later I get back Lumia: Description: device has been reset, "Settings" is set (which may mean always) and software reinstalled, and: test call. OK. So exactly what I had already done. The Windows version, IMEI, MAC addr. everything as before. When commissioning runs take first again the basic installation, I have inserted the SIM card and you only just over 24 went back out (when changing a calendar entry, but is always independent of any actions) Then there was again at 16:03. a "crash" as the mail with Windows update available arrived :-) Now I have "Denim" (WP 8.1 update, 8.10.14234.375) Now I am hopeful - as yet no restart "knock on wood" (SD card is in there again, Germany map downloaded)
Positives: Here Drive, free map, good GPS reception Optics and size like me
