Hello,

Awesome XDA developers. I am seriously in need for some helping hands for my Tablet PC. I have got a China Octa Core 7 inch tablet pc with WUXGA display, MT6592 Octa Core processor, 2GB RAM, 16 GB ROM, Android 4.2.2 OS , 13.3 MP REAR CAMERA, 5.3 MP front camera etc.

So far the tablet is so good with Android 4.2.2 OS. The china company recently gave me an updated ROM for the tablet PC. The update includes Android 4.4.2 OS. I installed the firmware with SP Flash tool 5.5. After installing the OS, I was very happy to enjoy KiTkaT. Every thing were perfect.

Except one strange problem I am facing with Android 4.4.2 KiTkaT upgrade. I can take photos in 13.3 MP high resolution with the rear camera. But when I record videos with "Fine" recording mode or any other modes (low, medium high or fine), the video gets recorded in 640x480 low resolution only. I tried every camera settings did not work. I also check the "build.prop" settings & "camerasize.xml" settings. But nothing worked. For both the front (5.3 MP) and rear camera (13.3 MP) records videos in 640x480 low resolution where as the same camera take photos in 5.5 MP (Front Cam) & 13.3 MP (Rear Cam) resolutions.

But for Android 4.2.2 OS, both the cameras could record videos with 1920x1088 resolution when you choose "Fine" as the video recording mode. I am a beginner level developer. I can not get anything to fix the problems. I reported this to the tab company, they said the firmware company can not fix the problems now. And asked me to use the Android 4.2.2 OS. I have also googled for possible helps with this firmware problems. I found that modifying libcameraservices.so & media_profiles.xml may fix the problems. I found the file "libcameraservices.so" and copied to my PC, opened it with a HEX Editor but am not that expert to correct it. Please help me.

Can the XDA forum experts help me with this miserable problems.

Please help.

Thanks & Regards

Those are libraries that are included in the firmware. Those can't be edited with a Hex editor. Not effectively anyway. What I'd suggest instead is to see if you can install Google Camera App.

But if that too does not work, then for you, the only other thing might be going back to 4.2 short of rebuilding the firmware with right libraries.

Thanks for your quickest reply to ma text.

I installed google camera. After getting it installed from the play store. It closes with an error when I try to access the camera settings. I also tried to do a trick by copying the "libcameraservices.so" from the Android 4.2.2 firmware & then copying it over the "libcameraservices.so" Android 4.4.2 firmware. Then I rebooted the phone, but it got stuck in the boot logo never rebooted.

Is there any possibility to correct the parameters of libcameraservices.so (Android 4.4.2 firmware) to fix the error..?? I am not that expert in building a custom ROM yet. Can you please help me out..??
