Finally some news from the Karbonn brand, the Karbonn A18 is now available for a price tag of Rs. 9,790. This is a dual SIM single core ICS powered handset with a WVGA IPS screen.
Karbonn A18 – a dual SIM dual standby ICS phone can compete well with the Micromax A100, though the A100 does have that 5 inch advantage. But with the entry of A18 the older handsets namely the Spice Mi-425 and the Karbonn A9 will soon be pushed to the brink of extinction.
Processor and Display Screen
Though not much info about the processor is known however for the price it is safe to assume it will be a single core, but we do know that it is clocked at 1GHz possibly with a GPU similar or equivalent to what we have seen on Mi-425 and A9.
The display screen is with a WVGA resolution i.e. 800×480 pixels. It is IPS capacitive touchscreen, even better than the Karbonn A9. The display screen on the Karbonn A18 is 4.3 inches in size (diagonally).
Memory and OS
Memory does play an important role and for this reason the A18 comes loaded with 1GB RAM (users are saying its 512MB RAM not 1GB – confirmed 512MB) along with a 1GB of internal storage. This combination is the perfect ingredient for the ICS (Ice Cream Sandwich) or Android 4.0 OS. Add to it microSD card is also supported of up to 32GB.
Connectivity
The Karbonn A18 comes powered with all the features found on its competitor phones like 3G (HSDPA – 7.2 Mbps), 2G (EDGE / GPRS), Wi-Fi / USB with tethering support, GPS, Bluetooth 4.0 and a 3.5mm audio jack.

Multimedia
Like every android phone this one too can entertain. The stock media player can play many supported audio and visual formats with easy.
Pre-installed apps
The A18 comes loaded with some games like Angry Birds, 3D games, live motion wallpaper, Kingsoft office tool and with customizable home screen. Social networking apps like Facebook, Twitter, Gtalk, Y Messenger, whatsapp etc too comes pre-loaded. You get full access to Google play from where many more apps can be downloaded.
Camera
The camera resolution is of similar specs when compared with other handsets in the same price band. It is with a 5MP resolution with LED flash and a 1.3MP front facing camera. This camera is enhanced further with added features like auto focus, burst mode and face detection.

Battery
A 1500 mAh li-ion battery powers the handset. This is too low as compared with Mi-425 or the Karbonn A9. But it should still give a better or equivalent standby and talktime.
Karbonn A18 key features and Specifications
- Single Core (mkt6575) 1GHz CPU – GPU – Powervr sgx531.

Karbonn A18 review
The handset looks like an upgraded Karbonn A9. The design however is different but most of the hardware specs are similar to the A9 model. On some sites it is available for about Rs. 10,500 but flipkart is offering the same for as low as Rs. 9,790 with 1 year warranty.
Performance wise it should do better than the other models and should also get a higher benchmark score. But can the A18 compete with the Micromax A100 – let me know your views!

How many of them facing flickering problem when brightness high in karbonn a18?
i have
Hi Gogi
My phone A18 stuck on boot screen. It all happened when I tried to root my phone. Now it is stuck on startup screen and if press volume button downwards, it goes into recovery but doesnt read my sd card and if I press “reboot system now” it goes back to start up screen”karbonn smart”. Ive shown my phone repair center and he gave up and saying Ill have to send it to delhi for 25 days. Is it fixable. Help will be highly appreciated. Anurag…
Anurag, they will need to reinstall the OS and then test, I think the service centre should be capable for doing this unless the centres are just acting as couriers – sending handsets to main office and getting it back.
gogi my a18′s screen glass is broken…what is the cost of replacement ??
hey can any1 pls tell me IS UR HEADSET BUTTON WORKING FOR MUSIC CONTROLS?? MINE WORKING ONLY FOR CALL N NOT FOR ANYTHING ELSE…
also its been 4months i havent had any probs with a18 but now my display seems to be flickering especially when brightness is more…they said display needs to be changed…all m worried is abt quality of new display
yes sujit …my display also started flickering few days back….and who told you to change the display
Guys i am having the same problem with the phone. i visited the service centre almost a week back and they have promised to replace the screen. Now the key challenge is they are out of stock on parts. They are asking me 1 more weeks time so that they can get the parts replaced, if not they will give me an option. I will update you next Saturday about what happens.
Sujit, did you get your screen replaced or are you waiting for the parts like me.
hi Dr prashant,
How much time did they take to repair your phone? plz reply
Hey Gogi,

Hi gogi,
How to access pendrive to my karbonn A9 mobile with the help of OTG cable. I have a 4GB pendrive in hand. If i connect it is not detecting the pendrive pls suggest……..
Is the bare screen of the karbonn a18 scratch resistant?
gogi, one day suddenly my a18′s speaker’s volume doubled, then after few hours it came back to normal, what happened? i like that boosted sound?
Was it over all or just when watching movies. Could be an app (music app) with built in equalizer that might have left the same activated for long.
it was overall not just media players….n is there any way to increase the speaker’s volume ??
Hi..I had faced a problem in connecting mass storage to my pc with The U sb cable.. later I found The problem was in my U sb cable that I used for charge.(+it only charging when connected with pc .. no pop up for U sb option .. )l tired other cable it works properly..
Hi Gogi,
I have just recivied a Callmate USB OTG cable and connected the same to my Karbonn A18. There is no change that happens on the phone when the device is connected. I have tried connecting a mouse and pen drive still no go.
In the forum below there are few others who are struggling like me to get this to work. Would be great if you can assist.
Thanks,
Amandeep.
I have not checked the A18 but on A110 in storage option at bottom I see an OTG option may be on A18 ROM the OTG is not enabled.
You are right gogi, OTG is not enabled in A18 kernal. Amandeep try flashing ics otg module in CWM recovery it will work.
Rahul could pleas explain this how to flashing ics otg module in CWM recovery
How can Iconnect otg to my karbonn a18, and pls explain how to cwm and how to recover.

And when I do restart phn, my problem got sloved for few minute,afterwards same problem again
Reply soon
Faced a similar problem on Karbonn A7, your sdcard could have failed. Try using another SD Card and it should work fine. Nowadays cards from Strontium fail within the 2 months of purchase.
Hey Gogi,
There is one issues with my karbonn a18…..i have a folder named mtklog stored in internal storage and memory is abt 1.9GB ..when i delete that folder it again appears after 1 day…..really have no idea wat is this?
Dear gogi,
its a superb support from ur side for all the mobile users, from past 1-2 month i am using KARBONN A18 mobile. Everything is ok with this handset. but only issue i am facing is GPRS problem. my all the setting are ok. but i am not able to get continue connectivity even if network is full and many time friends are informing that they are not able to call me bcoz call is getting disconnected. even if i am having full network. I change my vodafone sim card 3 time they provided me 32k sim last two time and just today 3rd time they provided me gemelto sim card. but still facing the same problem. 2nd thing i try my mobile sim card with other android like SAMSUNG GALAXY S-2 and INTEL XOLO 700 and i am surprise net was working properly with this other mobiles.
When I done internet speed test on different mobiles. On KARBONN A18 in 10 time 6-7 time message comes network connection error try again and rest time it gives speed of 5kbps to 30kbps. (test done through speedtest.net)
On XOLO 700 and S2 it was connected properly every time and speed was in a range of 60-70kbps to 180kbps
My big prob. is incoming call after trying many times it get connected.
Now at current point i am not able to understand what to do with this prob, its clear to my that is prob. is not with network service provider. Its with the mobile hardware.
Now I am thinking to exchange this mobile with another mobile. Because I really don’t know how is the CS of KARBONN mobile and will they solve my problem and how much days it will take. So please give me some guidelines. Thanks and regards.
Nithin, Try the following steps
Settings->WirelessAndNetworks->MobileNetworks->GSM/Umts Options->AccessPointNames.
Over there go to options and select “Reset To Default”. Once done reboot your phone. Hope that helps
PS:I own micormax a70 so the above steps are like how I see it in my phone. The navigation should be similar in our phone as well.
