Gionee is just trying to make more money or just couldn't develope software update for 4k video. Well what i can tell about this subject is i heard that they are gonna make a new E series model, if upper device has the same chip for camera with 4k video recording, you can just flash that mod on your E7s.

it most likely has 2 mipi lanes which are not enough to carry the bandwith for 1080p res

can you upload this file i think i can enable 4k for gionee
libmmcamera_ov16825.so found here /system/vendor/lib/

Attached is a modified LIB I have Changed the THE Video Res from Half Size to Full.

So Now it should record at 4608 x 3456 30fps this is enough for 4096 x 2160 DCI 4K or 3840 x 2160.

Another thing i dunno if media profiles contain the 4k res so you may need to edit those

Code: 
    <EncoderProfile quality="4kdci" fileFormat="mp4" duration="30">
      <Video codec="h264"
            bitRate="100000000"
            width="4096"
            height="2160"
            frameRate="30" />

      <Audio codec="aac"
            bitRate="156000"
            sampleRate="48000"
            channels="2" />
    </EncoderProfile>

    <EncoderProfile quality="4kuhd" fileFormat="mp4" duration="30">
      <Video codec="h264"
            bitRate="100000000"
            width="3840"
            height="2160"
            frameRate="30" />

      <Audio codec="aac"
            bitRate="156000"
            sampleRate="48000"
            channels="2" />
    </EncoderProfile>

then add this to the end of build.prop

Code: 
persist.camera.4k2k.enable=1

lastly

Download Freedcam from Playstore Run it Swipe Left Settings > Save Camera Parameters

Check in DCIM/freedcam for txt file save it change lib

after lib change and restart there should be new res added to video sizes

looking at these specs sensor is very capable
Ive also attached a bookmark for hex workshop

below is the format of res

in the source code

its like the this
Code: 
.x_output = 3264,
    .y_output = 2448,
    .line_length_pclk = 3584,
    .frame_length_lines = 2480,
    .vt_pixel_clk = 133400000, // = line_length_pclk*frame_length_lines*max_fps
    .op_pixel_clk = 320000000,
    .binning_factor = 1,
    .max_fps = 15,
    .min_fps = 7.5,
    .mode = SENSOR_DEFAULT_MODE,

in hex like below each group of two numbers is one byte
Code: 
00 09
Code: 
C0 06[/CODE[CODE]] F8 02
Code: 
DA 06
Code: 
00B4C404
Code: 
00 D0 12 13
Code: 
01 00 00 00
Code: 
 00 00 F0 40
Code: 
00 00 70 42
Code:

    Hello All, Im very interested in having 4K video recording on our E7 device..As you all have seen the camera sensor OV16825 is very capable of recording 4K and our processor too is capable of handling 4k at ease.Ive contacted many devs for this but some are saying that its too much to want..only person helping me is Jishnu Sur. yes the guy porting 4k and 120fps to G2.Ive continued to study all the things and at this time i came to the conclusion that it looks there is little hope.. See the pics ive attached first is of gionee camera app second one is of one plus one. any body willing to help??
