Quoting Mercedes-Benz 240:

What processor does this phone use? What is the maximum video frame rate for video playback?

iphone sdk for tech info cpu is 400mhz. For max frame rate we not test, it support 480×320 video play,

I propose to discuss a new phone on the market Plnphone 3GS. In my opinion it is almost 100% copy Iphone 3GS (size, ears, charge USB-cable all like the original).

My firmware version:
I835S_FN_CA_W_V1_0_7 on 14/10/2009
Languages: English, German, Russian, French, Spanish, Turkish ... (12 pieces, Russian good except for a few moments:))

Display:
Claimed that it was «Japan Sharp HVGA Capacitive TOUCH screen, This is same like IPHONE» and it really possible to believe, because the screen reacts to the excellent soft touch of fingers. Image quality and color is simply stunning. The screen is protected by something in the likeness of glass or rigid plastic.
However, almost all of these phones have one bitomu pixel in the corner of the screen (maybe it is on this the price is reduced) is almost imperceptible.


Menus, icons, wallpaper:
Menu, animation, interface, at a height and much better than all the other clones that I have ever seen! Everything runs very fast. Icons can be easily moved around the screen and on the next page or a new menu. You can set your own wallpaper.

Image Viewer:
There are two folders. Folder with pictures and photographs made by the camera folder. Works slayding images (very fast), reacts to rotate the device (everything, even upside down.) Scale with two fingers as the original. When you click on the image can be immediately set as wallpaper or send via Bluetooth.

Camera:
Provides an acceptable image resolution up to 1600x1200 pixels (2MP) (In my opinion the camera about 1.3 MP sprawling program of up to 2). White balance settings (auto, daylight, etc.) are also available as effects such as sepia, grayscale, and so on.

Phonebook:
Both IPhone

Compass:
works

Sound Recorder:
Works fine, looks very nice.

Video Player:
Supports, 3GP, MP4, RM, and, FLV video! I have no brakes were videos and clips encoded MP4, DivX, XviD, avi compressed to 320x480, 25 frames / c, Bit Rate 250 - 450.

Audio Player:
This phone normally does not support album art, you can install the cover on the individual files, but impoverish songs on the album I could not get. The player does not sort songs by artist and album (probably me some kind of glitch, or I just did not look).
Sound quality I am very satisfied, there is an equalizer and several sound effects. In addition the phone has a 3.5-mm jack output, so it can be used with any headset or headphones.


SMS / MMS
Everything works very nicely and quickly, there is a magnifying glass when writing messages, the ability to copy / paste. If enabled the Russian language in the settings, then when writing SMS Russian varies only in English (and not through all 12 possible languages) is very convenient.
Support landscape keyboard in this firmware, no!

User Profiles:
You can install up to 5 ringtones on their phone calls, the alarm clock, SMS

Chchtenie electronic books:
Only TXT files

FM radio:
Works fine, headphones must be plugged into an antenna. Can record, but I have not yet been tested (for me it is absolutely not interesting)

Java:
Works fine, but the application must support 480x320 pixels.
