How about Cool 1 mobile phone? Tell me about the used ones, and ask the great god for advice? thank you

It took me half a month. In short, the hardware is worth thousands of dollars, and the most important thing is that the battery is durable. It's okay to use it for two days. Although the dual lens can't improve the image resolution, the brightness and contrast are obviously improved. The system is smooth, but the rest can't be worse.

1, there is no shortcut menu. When the screen slides down, you can only see the time, date and weather forecast on the top line, and other areas are blank, which is very wasteful.

There are three function keys at the bottom of the screen. The general function menu key is on the left side of the system, and the LeTV system is changed to the background running program view key. At the same time, you can also see the music playback control system and shortcut menu. Although the shortcut menu can be adjusted, only 10 choices can be seen. This has caused many programs to find function menus. For example, the SMS screen can't find where the automatic signature setting is, and it can't be found in the system settings.

3. Share the phone number of the contact from the contact, and even share the vcf file.

4. You can't add desktop widgets.

5. You can't choose SMS ringtones and notification ringtones from local music.

6, mobile phone remote control is better than nothing, with Kelon air conditioning, you can only switch on and off the power supply, adjust the mode and wind direction, but not the temperature and wind speed.

7. There is no speed dial setting.

I think for LeTV, Coolpad has discarded all the excellent things in its own system.
