[Galaxy S II Q&A, Help & Troubleshooting] winlinmac001:
Here is my take,

I purchased my Samsung Galaxy S2 in India

My Samsung Galaxy S2 is stated as Made by Samsung, and the battery is Made in Korea, Finished in China. According to the Technical Team at Samsung India, they remain unsure about my phone's whereabouts. They are depending on Date of Import and origin of Manufacturer, so this is pretty much, unreliable information.

According to my box, it states Manufactured by: Samsung Telecom, etc (China),

Date of Import: June, 2011

The early batches sold in India had the incorrect spelling of AMOLED as AMOLDED displayed on the front of the box.

Pathetically, it took Samsung India two months to address this typo.

The July, 2011 batches have the AMOLED spelling corrected and they are apparently manufactured by Samsung in Korea itself. However, there is one interesting point I found on the Place of Manufacturing which appears very deceiving--> When I went to a nearby dealer, the July, 2011 box displayed Seoul, Korea (With a P.O. Box Address in the line above the State, Country, etc)

The early Samsung Galaxy S2 phones sold worldwide in early-May had loads of defects ranging from, "Suction-cup coin-shaped shadows on the screen display, Dead pixels, Banding, Yellow-tinge, Uniformity Issues, and so on." Those devices were sold mainly in parts of Europe, particularly, the United Kingdom (U.K.). According to many U.K. Forum Users here and other Forums, their devices were manufactured in Korea by Samsung. After understanding that, I was a bit relieved to see my device Made in China expecting no issues to be found. However, question remains, is there really more than one manufacturing plant, or can all the S2's sold mostly around the world be manufactured in China itself?

Now, there is no way of really telling where the exact origins are. According to my S2, it was manufactured in the 2nd week of June with a time stated in Korea Standard Time (KST).

My phone has cleared the initial test on almost all the defects reported on XDA, which are absent, except for the suction-cup issue which is "possibly" present. Although the shadow is not as visible and extreme as what others had posted on XDA, whenever I go to the Notifications Area, there is a "very-very" faint washed out circle in the top-right of the screen; hardly visible in normal light, not visible in photos (Gallery) and applications (you never see it, strange), in White/Grey backgrounds, from 0% - 100% brightness (in all brightness levels, shadow not visible).

The IMEI # on my phone begins with "3" just like the July, 2011 box I saw at a nearby shop, which additionally stated, Manufactured by P.O. Box...etc, Seoul, Korea.

Overall, my device is perfect, and according to some Indian owners that purchased the first batch (which had the label Made in Korea), they didn't get the box in the condition they wanted it to be. Some had their S2's packed without any labels on top and bottom of th device (no Samsung-logo screen protector), dust in many areas of the box, and unsealed batteries and cases. At least, I didn't have to go through all that with my Made in China Box.

Most importantly, one thing that concerns me are the future S2 devices Samsung is going to sell. Many phones from May were returned to Korea because of defective displays, and faulty units. I would be very uncomfortable to note the company using aftermarket, refurbished, used parts on their newer devices.

Is Samsung receiving defective units from previous S2 owners, shipping them to China/Korea factories and reinstalling refurbished parts on their newer batches? You'll never know. Do you really think the S2's are really coming from Korea? You'll never know.

Ultimately, I'd have to say, I strongly believe all Samsung Galaxy S2's are made in China. For all intent and marketing purposes, Samsung decides to give its customers mixed-feelings.

Rather, I feel Samsung should label should mention, Made (Designed) by Samsung in Korea, Finished (Assembled) in China.

Almost all the parts that the Samsung Galaxy S2 contains are Made In / Coming from China.

Shipping them to Korea for Assembly costs money. My Box states "...Factory, China," fresh-out-the-kitchen, lol. What is originally made in China, Stays in China, and Assembled in China.

Samsung Factories assemble products in batches, it could just be coincidence that the labels are changed every one in a while. In India, it could take a while for the main distributor to decide what labels to permanently stick on the phone and box for all future devices sold. It took 2 months to display the correct AMOLED spelling on their boxes; it must have come to a conclusion to display Korea on their boxes and phones because that is the origin of Samsung, keep it plain and simple. Korea is also a distribution channel for shipping their devices in bulk to other parts in the world. Its possible all of the S2's are Made in China and shipped to Korea for restock purposes. Because of the influx demand in India, some devices may have managed to come straight from the factory in China instead of going through normal protocol; that is why my box has the manufactured by: China...Factory...Samsung Telecom, etc., label.

Hope this gives users a better sense, something logical to think about.
