  • Digital Multimedia Broadcasting (DMB) is a digital radio transmission technology developed in South Korea[1][2][3] as part of the national IT project for sending multimedia such as TV, radio and datacasting to mobile devices such as mobile phones, laptops and GPS navigation systems. This technology, sometimes known as mobile TV, should not be confused with Digital Audio Broadcasting which was developed as a research project for the European Union. DMB was developed in South Korea as the next generation digital technology to replace FM radio,[4] but the technological foundations were laid by Prof. Dr. Gert Siegle and Dr. Hamed Amor at Robert Bosch GmbH in Germany.[5] The world's first official mobile TV service started in South Korea in May 2005, although trials were available much earlier. It can operate via satellite (S-DMB) or terrestrial (T-DMB) transmission. DMB has also some similarities with the main competing mobile TV standard, DVB-H.[6]

  • Well, if you install Go SMS Pro you will sort out the 80 character limits for sure, just make go sms pro the *default* sms progam on your android and there you go, you are done. You dont need to install custom rom to sort that out, always the original firmware is the best choice for the phone, if you are experienced user and want to look out of the box, then you can root, custom recovery and custom rom for your lg, just check xda developers site, or lgsoviet site ( translate with chrome)

  • Great cel phone in andriod.. i love this model

  • Great cel phone in andriod.. i love this model

  • Hello..I have been using this phone since last 5-6 months...no specific issue at all...and for all those who are complaining about 80 words sms problem...just install GO SMS PRO from Playstore...Any other Question..([email protected])

  • I just purchased this phone from Korea. I live in Mongolia. I like my LG. But I'm having a little bit trouble. Okay, correction. A lots of trouble. First and biggest is my phone call won't ring, alarm won't ring!, notification won't ring!!, message won't ring!!! and music won't play..........!!!! No audio action...... What should I do?

  • hi to all LG Su640 users, for 80 sms limit issue and battery draining issue... i have found best remedy for all the problems. Just install this rom SphinX_V3_SuperCharge_V6_ForSU640 its a modified Original stock Rom 4.1.2 Jelly bean with added features and sms limit 160... and also install WIND_Kernel-r1_JB_SU640 this is also stock kernel will battery drain fix for battery drain issue... battery life would increase alot. for all above you first have to root the phone.

  • would you please tell how to do so?? coz i m having this cell phone and i want to fix this sms issue.

  • i heard somwhere that if english rom installed in it than gprs can work. is it true? i live in pakistan .

  • Actually YOU are the one who don't know much about android apps. Most of Korean phones limits the sms by 80 latin characters and cannot be easily fixed by installing GoSMS or any other SMS apps. You have to modify the smsmali.xml, framework-res.apk, but I guess that is something you don't know for sure.

  • I ve updated my su640 to jelly bean. But after updating, am not getting a notification when i get a msg. My notification seems perfectly fine but when msg comes am not getting any notification. I am using handcent sms app to send msg. I used go sms too but neither helps me.. Please let me a solution for this. Thanks in advance..

  • Hi! I lost the charging socket cover. Is there in stock?

  • Hi! Now I lost charging socket cover. How can I get it? Is there any in stocks?

  • This Phone is Not Available in other countries except Korea I got Korean USED in Afghanistan,

  • is it available in India.....?

  • I want to know if the have released this phone , i can not find it in Bangkok.

  • does this phone have gorilla glass in it?

  • its a very good phone and screen is superb.fast UI and internet connection is excellent. ICS rollout today but in SKorea only.

  • Battery life is not great, i mean very bad. I change battery every 6 hours evethough i dont use oftenly, rest others things are great.......

  • This phone is awesome, Its very fast and the display is just amazing, its thin and light weight, I just love this phone. However, battery life is not good. I need two batteries for a day. The battery drains very quickly may be because i use 4G connection.....

  • HSPA and LTE are GSM, though nobody's called it that since 2G days. Most phones bought from the carrier are vendor locked. If its that important to you, try manually installing Ice Cream Sandwich. If you use an unlocked image, you'll get an unlocked phone.

  • i hope battery has to be something more than 2000mA

  • its not a GSM phone, does not take any sim card. so you can't use it with any other carriers if you happen to go out of state or change carrier. THUMBS DOWN

  • whats the price

  • super amoled plus has rgb matrix

  • How is the battery life on this phone. I do not want to stay close to the power outlet when I am browsing.

  • This IPS panel is better then Amoled.

  • Pentile matrix display is related to Super Amoled displays. But here the display is IPS LCD which has RGB lines to form one pixel.

  • is it pentile like the galaxy nexus

  • Thanks LG .......This is realy Best mobile Phone.It is very fast...

  • This is real!!!!!!!!!! Best Phone... Fantastic..and very fast... I think Main LCD quality is pefect!!

  • I know what can beat a SAMOLED..........and RGB HD IPS display.

  • does the tv tuner work across the world???

  • nothing can beat super AMOLED..

  • LG please make this phone international!! it is by far the best smartphone avilable!! make LG RULE!!!!!!

  • nice very nice i like LG mohamed tibrizi sudan

  • Best Smartphone available in the market. with special features like 1. HD-IPS Screen (better than Super AMOLED Plus) 2. HD Resolution (720x1280) 3. 1.5Ghz Dual-Core Snapdragon Processor (Just Amazing!) 4. 8M Camera for 1080p HD recording

  • This handset is the best of sensation that a user can has!!!

  • LG make this phone internation, its by far the best phone available!

  • In what way? The specs look EXACTLY the same. The main difference that I can see is the DSP, the LG has 75 and the HD is probably a good bit less.

  • Yes, of course. All androids have flash support.

  • good job LG , but they copy Samsung.

  • is adobe flash supported?

  • but galaxy s 2 HD is better then it....

  • 135 g with this high-end hardware...... impressive! I will buy one!

  • Hope for a good price and come to Europe! Good LG!

  • What is its LTE speed?

  • Impressive!!!!!!!!!HD screen n pixel density is equal to iPhone 4.well done LG
