[Android Q&A, Help & Troubleshooting] khankll:
hi

i have samsung galaxy s3 clone . it was bought in china .. i dont know who made it ..

it is mtk6575 based device .. with 2 sims .. one micro .. and one min which was hidden .. with dummy sim and plastic cover .. and its 4.7 inches display .. its 800 X 480 resolution.. ram is 512mb .. total rom is 4gb (dont konw how to tell what it realy is . but i think this figure is correct ) internal sd card is 2 GB ..

i have also posted pics of the motherboard in a zip file in full resolution.. also posted the cropped versions ..

the board says

Model:1212 [there is some thing in chinese inbetween ..

SW: 1212 v23-1101

Date: 2012-11-14 ZKD or ZKO

.

here is some more info i gathered ..

here is the info from AndroidSystemInfo app

it has few issues ..[except rooting all is stock as of now]

1: GPS not working Working after new rom, but weak signals [edit date : 9th january 2012] :good:

i cannot make the gps locked onto satellites .. i have tried a lot of gps softwares like ulysse and others.. but even after hours of being under open sky i wasnt able to get it locked .. i used the agps and the epo .. still no luck .. using the EngineeringMode and going to ygps i could only lock it onto 5 satellites .. but its signal was very weak .. it quickly lost that .. so is tehre any solution ? also i tried it under open sky and also tried it on samsung galaxy mini and had no issue in locking onto sattellite ..

2: Camera not taking pics in full resolution now its natively taking pics in 8MP and quality is also improved . but other apps still show image inverted in viewfinder . only UCAM shows correct orientation. [edit date : 9th january 2012] :good:

it has 8 MP camera but android is only taking pics in 5 MP and i cant seem to find any settings for setting it to take pics in 8mp. i have tried another app Camera FV-5 and was able to take pics in 8 MP .. but that app and all other apps that i tried gives me the inverted viewfinder and i couldnt find a way to correct that ..

3: Compass showing wrong direction still showing wrong orientation . [edit date : 9th january 2012] :crying:

when i use compass app it shows wrong orientation .. it shows east as west and west as east .. i have checked it in open space and my other phone samsung galaxy mini had no issue in telling me the direction ..

4: SD Card Size is shown highly inflated: see pics .. the last 2 are from link2sd now all the sizes are shown correcty after update of new rom [edit date : 9th january 2012] :good:

sd card size is wrongly reported .. very inflated size is shown .. in this circumstances the internal sd card /builtin sd card is 2gb .. and external sd card is having 2 partitions one is 2gb other is approx 12gb. as correctly shown by link2sd (pics given below) and many other apps... though the card is ok .. tested on my pc .. its original sandisk card . and works ok on other original sets .. i.e. its shown correct size there .. also correct size is shown on pc ..

also other softwares on this set report its size correctly.. like link2sd and other system info tools..

5: Only one IMEI is shown. well still i have only one imei . but no issue due to it .. [edit date : 9th january 2012] :confused:

originaly this set had one micro sim slot . but on probing the sticker i found anothe mini sim slot .. and i removed the plastic wrapper a bit and inserted another sim .. and now my phone is double sim.. both sims are working .. i havent checked them thoroughly .. but i can recieve sms and ring on these sims .. no issue . but when i enter *#06# only one imei is shown .. ? why shouldnt it display 2 ? also when i enter factory mode it shows both imeis .. Strange .. anomaly..

6: No Google Talk present. though i have google play i got it working .. [edit date : 9th january 2012] :good:

it lacks google talk . though it has google play. i also need gtalk on it.

7: Is it realy MT6575 as shown by various softwares etc or is it MT6515 stil dont know . but it should be mt6575 ? [edit date : 9th january 2012] :confused:

many fellows here bricked their similar mt6575 devices and in the proces of resurecting it they found it to be mt6515 not mt6575 as intialy shown to them .. so how can i tell which is mine in reality apart from prying it open. i am currently using it on GSM network. in the process of installing CWM i used Scatter file of MT6575 . also when i used mtkdroid tools 2.3 to take backup .. i then used MTK Rom Studio to build the scatter file from the firmware.info file generated by the MTK droid .. when i saved the file created by MTK studio it automatically named it as scatter file for mt6515 .. strange ? that makes me suspicious. i am attaching my generated scatter file . it is same as that of mt6575 .

i am posting few pic .. and also attaching them in full resolution as xda downsized their resoution .

waiting for any help thanks
