Clear the smartphone also has weaknesses, but from the entry level it protrudes through his memory and the quality of the display already out. The battery lasts for 2 days at me. The display surface attracts fingerprints magically. One star deduction I distribute but because of the unlit function keys. In the dark the flying blind is real even if you as an Android user really knows where the key would be. That is just not long enough to hintrifft also immediately there. Addendum of 16 May 2015 by an operating system update to version Holly-U19V100R001C577B115 the problem of incorrect labeling of the button "Mobile data" and "rotate screen" is solved.
