LG C900 Optimus 7Q - User Reviews

  • Let me see if its better than lumia 520.. I believe LG is good and can have good quality

  • Its an excellent phone its only that some of the things are hard to operate

  • Its an excellent phone its only that some of the things are hard to operate

  • My phone does not support Bluetooth

  • So I really can't use it I can't download any apps

  • My phone doesn't support Bluetooth and how do I update it

  • This phone does not synchronize music from my competed and I have a problem with Bluetooth saying not supported

  • SIM used on this device is mini SIM. I guess you are talking about micro/nano SIM. Standard SIM would be mini SIM, but back in late 90s and Early 2000, SIM card used was just "SIM" card, which is size of a credit card. That's why they are calling mini SIM for the size of SIM card used on this device.

  • from what i see its best to HARD RESET before using the device.............

  • Pls can anybody help me? my C900 cannot detect any network signal in Ghana. neither mtn, vodafone nor airtel work on. it detects it only when i am very close to the network pole but with poor signal strength.

  • My Bluetooth not working. Always give the notification of device not supported. From where I download Bluetooth share for this mob because Nokia Bluetooth share is not supported in this

  • For all those people who still own the LG C900 and have been facing with various kinds of issues except batter I highly recommend you all to Coldboot the device and try using it. Cold Boot How? Simultaneously press the camera button, Volume + and - and the power button hold it until you see the Cold Boot show up on the screen then release the power button and keep holding on (pressing) the Camera and volume + & - until you see the screen show Cold boot and the LG Logo reappear with the welcome screen. I've been having issues myself with the device so, after 1 unsuccessful cold boot I gave up, after looking up on google and searching around I noticed that the cold boot done was incorrect by me, I tried again and Viola! I started working no more hiccups etc..,

  • My app is not coming what is de problem

  • To update it to 7.8 you must DEBRAND the phone using these steps... --Enable the MFG application by going to the dialer and dialing ##634# then pressing call. LG Phone Problem and Solution --Launch the MFG application and enter 277634#*# when prompted for a password. --Select the Engineer Menu item. --Select the Other Setting menu item. --Select the Edit registry menu item. --Set the input boxes on this menu as follows: --Select ROOT_PATH: HKEY_LOCAL_MACHINE --Input SUB_PATH: \System\Platform\DeviceTargetingInfo\ Input KEY: MobileOperator Data Type: STRING --Select Query and write down the result for re-branding (just in case) --Hit query, and write down the result (used to REBRAND after the update)**** --To DEBRAND change the input data field to �000-88″ then apply the changes --Connect to Zune and check for updates. ****If you wish to REBRAND the phone, input the query result

  • Hi Guys anybody from #XDAForum here? I have some issues with my device, when I used the mfg codes to access the software test I realized there's a error [HKEY_LOCAL_MACHINE\Drivers\Builtin\RIL] "dll", mmril, mmrildbg.dll Due to which I haven't been able to upgrade my os to 7.8 though I did it once after I connected my device to zune it restored the OS back to 7.5 since then I haven't been able to upgrade even using skype.

  • It works just fine with Vodafone IN, Airtel IN and AIRCEL IN and the rest of the 3G providers in India.

  • I got this mobile unlocked from US. Very poor batt. Otherwise working fine. And i see only accesspoint names configuration to connect to internet. Will 3g work in India on this?

  • Actually the phone works better with 3G service! Works like a charm, I made a point looking up some specification and I noticed certain application need higher data speeds hence no more sudden shutdowns etc.., Working great, I just love the Skydrive app it become easier to share documents over skydrive retrieve info make changes and save it on skydrive. Its a beautiful phone. The Best part is the Keyboard the chicklet design makes it comfortable and easy to type faster without making any mistakes.

  • Connect your phone to pc via usb cable. Then run Zune, and zune should update it automatically. =)

  • It's a great phone for a cheap price. I brought it on eBay, and i've owned it up to now(for 10mos). It runs on windows 7.5 updated automatically on Zune. It's smooth and has very responsive touch screen. All i wait is the release of windows 7.8 since it will not be receiving windows 8 os. =)

  • I too got myself a the LG C900, just today! So far its been good but, like many have pointed out in the review the speaker phone crackles when the volume is raised to maximum. The best part of this phone is the email client, MS office (which I really needed as none of BB service offer until you pick up a high end device.) I also noticed that the touch screen is quite sensitive and at times doesn't register touch when it been touched from the corner of the screen, not sure if its only with my device or for everybody. I would really need some help on updating this device to WM7.5 I've got the AT&T unlocked device and was wondering how can I get the phone OS updated to 7.5 Appreciate your help! Ty guys!

  • According to your usage, it will last until you arrive home if you fully charged it before you go to work at morning, but I suggest that you should buy moblie charger (I'm not sure what it actually called) like Sanyo Mobile Booster to ensure that you won't miss anything important.

  • does anybody know , how to unlock this phone from at&t to use with indian gsm networks ?? thanks in advance !!

  • Hi i want to buy this phone, and just want some opinionon below pints. 1. Hows much the battery lasts on average usage of like 2 hours of talk 10-15 msgs and 1hr of net surf. 2. Is the earpiece gives some noise while talking over the phone. 3. Will this phone get locked again after updating to Mango Thanks in advance

  • to update to 7.5: -turn on wifi on pc (not phone); -attach phone to pc via usb; -fire up zune software on pc; -go to Zune settings tab, select GEneral option; -choose Check for updates; -follow instructions on scree.

  • Hi Thanks much for your response again! I'd like to know have you been able to upgrade this device from WM7 to WM7.5 (Mango update?) I apparently need multi-tasking & cut-copy-paste while sending mails. Has anybody successfully updated their c900 to the new Mango OS?

  • Battery will last a day w/ moderate usage, a couple of days with light usage in my experience. I love this phone and generally recommend it, but if you really are a heavy user, you might find the battery life insufficient. A car charger or extra battery might become necessary.

  • Hi, need some info from people who have used this phone and who have been previous wm users. I am a heavy user make roughly about 100 to 200 calls a day and lot of emailing and little fb n' lot of tiwtter useage. Could you let me know based on your experience how long does your phone's battery last with one charge. Thanks much for your response!

  • a Great phone.wonderful.I am using that phone.

  • Go to web browser setting and allow cookies on your phone

  • it wont let me buy anything on the pone. ex) youtube is free and it wont download to my phone. Also, my phone says its do for an update i plug it into my computer and nothing happens. Love this phone but its getting annoying anyone know how to fix my problem?

  • i like the design and color. too bad it's not android.

  • Restore your phone somehow... there is no way to recover your password, cellphones are programmed to lock you out permanently if you input the wrong password too many times, so if you find a way to restore it, kudos to you, otherwise, you've got a useless $300 piece of junk on your hands, and I know, I own one...

  • made new high define phone

  • I forgot my password, 4 numbers, this is one of my older phones, anyone knows how to open when you forget password, so hard to download manual. thanks

  • some of these people have no idea what they are talking about when it comes to this phone. Check it out for yourself and decide. Most of these people never used it or own it.

  • Does anyone know if this model will be available in Europe? Optimus 7 is currently the cheapest(~220�) simfree wp7, and i quess 7q would not be priced too much either. The only qwerty wp7 available is htc 7 pro, and that thing is expensive as he'll (>500�)...

  • The battery life is fine if you have edge on and low brightness :)

  • Love the phone. Does everything I need it to do and more but the battery life sucks

  • The only downside to this phone is the battery life. Other then that, it is an excellent phone if you are a business person that utilizes the Office 2010 Mobile apps. The 5 meg camera with flash works excellent and the video is crystal clear @ 720p. If you have a bluetooth television you can play your videos on it via the "play to" app. It also will hold all types of email accounts. It is a heavy phone due to the insides. (processor, RAM, and storage) Text messaging is a breeze with the keyboard. Receiving emails on several accounts in real time in also a plus.

  • It would be great if every phone with "scratch-resistant" display had that expression in the specs, so if one searches for that expression, all of them would be listed. like iphone 4 and some others. Thanks.

  • A WP7 phone was featured in an episode of Hawaii-5-0.

  • wat's d cost

  • as well have tried the HTC and the Samsung Focus. LG i find the best of them as it has the keyboard and the screen is still plenty big.

  • i have used this phone a few times and am purchasing now because this phone is excellent. 1. keyboard is easy to use 2. Windows 7 Mobile is very fast and easy to use. 3. the phone feels solid 4. the screen is excellent and very responsive. highly recommended to try out.

  • I have to agree with the people who have tried it in person, the photos really don't do this phone much justice. I saw the online photos and thought the phone looked cheap and I happened to see it at a frys electronics so I thought I would at least play with it for a minute. It actually felt really good. The phone had a really nice weight to it and felt solid and very well built. The keyboard was really nice to type on and I personally didn't have a problem with the shift key, but I have small hands. The sliding mechanism was solid and felt nice, I sat there and opened and closed it for a little while. The screen is what really suprised me, it did not look good in the online photos, but it was great in person. It is a little disconcerning that the home screen doesn't reorientate to landscape but I'm hopeful MS will fix that. So I suggest to check it out in person if you can and if you like it they are going for like $300 on ebay.

  • This phone or any phone running Windows Phone 7 should be featured in some movies and a couple commercials at least. This phone software is amazing and the capabilities are almost endless. Yes the phone turns to landscape no problems for me and the typing is excellent with the real and virtual keyboard. Don't depend your buying opinion because 1 person gets horned up and voices negative things. DLNA playback at home is awesome too!

  • I live in Melbourne , Australia today I went to the Telstra shop in my suburb and had a play with the LG C900 Optimums 7Q first impressions were very positive ! I don't know why almost everyone is bagging this smart phone !

  • With the updates coming in January will the Landscape mode be fixed with this? My wife loves this phone and I'm thinking about getting it for her for Christmas.

  • Mike U sure about the screen not rotating to landscape mode? Have u used it? I mean look t the feature it got a accelerometer? Early replies would be appreciated...

  • Have u used the phone mike? Its got a accelerometer sensor of auto ui rotate so how can it not switch to landscape mode.? And are there any other problems with d phone

  • this phone is not user friendly it is not selling well in Australia , consumers are not pleased and retailers are not pleased with the screen as it does not rotate to a landscape view making it cumbersome to use and a waste of money to invest in. It cannot live up to its potential.

  • Actually, the keyboard is fairly large compared to most keyboard smartphones, I think it is targeted for males. Keyboards is one of the biggest complaints among males.

  • Why not concentrate on both? It's about market share and the more customer you get the better the business.

  • With technology becoming old in 7-8 months.. there is no point in purchasing this phone when it is released.. Wait for an year... the same phone can be bought for half the price..:)

  • LG, LG, LG, No wonder your phone sales has dropped. Who is the LG'S CEO now? A lady or a GUY? If it is a lady, I am not surprised. A lot of your phone are oval shaped and having colourful keyboard. They are like flowers. Try to design squarish phones. Your phone spec are one of the best in the market. To me, Oval shaped slider phones are not suitable, It look like flower petals when you slide it, look at the pictures. As if they are meant for ladies only. It will be quite embarrassing to me personally, carrying flowers all day long. Don't know about you all. Please design something "UNISEX".

  • Deign of this phone is to old....

  • ram and wifi

  • optimus 7Q or HTC 7 pro.. hmmmm...

  • So Far it has the best design out of WP7 devices! Like it very much! :D

  • Quantum is the exact same phone but for AT&T (US Market) like Galaxy S has many versions (Captivate, Fascinate etc.) for different US telecoms (eg. T-Mobile, AT&T, Verizon and Sprint)

  • lg should concentrate on android not on windows

  • :) nice phone, looks great, better then al other wp7 phones 11.10.2010 tumkur

  • Only the Ram is the difference? Strange...

  • What is the difference between this and the Quantum?

  • the first QWERTY Windows 7 Phone! Looking forward to it :)
