Since my wife wanted to see on their daily train rides no longer on the 4-inch screen of your phone, now has the A7-40 with 16GB and GSM. A 10 inch monitor is too large for the daily journeys and to difficult and so this device had the right size. Where about the weight of this 7-inch monitor is uncomfortable after some time when you have to hold in your hand always. After unpacking, SIM cards, memory configuration, load and a short setting, the device immediately wanted to install the Android version 4.4. Recommended, but is set up the Wi-Fi access in advance. Although the file is 1.1 GB in size, the upgrade process goes quickly and without a hitch. It is important to know that you will lose all settings and saved addresses made to date. Fortunately, however, the wireless key has been preserved, which with me has 23 locations and characters from the entire character set takes. So it was always a bit annoying to enter. Also you should never have zeros and large Os in password, there is always confusion. After turning the unit then did what is expected of him. Games, great photos and movies are displayed without jerking. The wireless connection works fine and both cameras do what they should. HDR shooting function, only it's hard to keep the tablet steady during shooting. Skype is more pleasant than on the laptop you can show everything without marching with the open laptop through the area once just. The screen is not as gaudy as the screens of our phones and Samsung might not really quite as sharp, but still very good. I have installed an additional 16GB SD card, but in which already 16 GB of internal memory actually goes a little card. All games, office programs and also use the included, very good navigation program running properly. However, Lenovo has the device unfortunately littered with programs that can not be extinguished in part, but you can disable at least. As used for storage that actually makes no difference, only the screen is a bit tidier. The repeatedly mentioned, blue housing color I feel sometimes very pleasant. The main thing the device is not sensitive to white and you do not buy fruit Store apps and music. I had already gained some experience with other tablets that are so often sold at special prices. Unfortunately, just about all only a large 8GB memory and then is no longer enough, if one. On Android 4.4 upgraded because the memory usage has been changed The 16 GB are therefore a must. Pleasant also the possibility of GSM usage, particularly when we get here in Sweden a month for 1GB below EUR 50 annual fee. Even with frequent Spotify has so far always been sufficient. I would recommend the device so, taking into account the price, would recommend.
