As such, the mobile phone is compelling and high quality. It is narrow, fits comfortably in your hand and makes a visual impression of high quality. The display is crystal clear and the colors are brilliant. The unit has both a bakery as well as a front camera, whose resolutions are okay. On the left side there is a rail which is provided with a button which was known only as a reset button to me so far. Here you need a paper clip or something similar. Then you can go out this rail, the first summarizes a micro SD card and further inside the micro-SIM card. This is practical and innovative, as easy to use. Simultaneously, the SIM card will not fall out when you want to change the SD card, as this is the inside not having withdrawn by placing further. Important Note: the device can only use a micro-SIM, not a regular SIM card.
Is a bit irritating that there is only a single touch field, namely for the main menu. A back button no longer exists in this cell phone. Also the fact that the battery does not replace, is a clear shortcoming.
My biggest problem, however, as mentioned above, the Firefox OS. If I want to upgrade from my previous Android phone, I have to present without diverse (favorite) Apps, which does not exist for this operating system. These include not inconsiderable features like WhatsApp and threema. For this reason, the present device is currently here for me as a smartphone beginner no switch alternative.
