Karbonn A40 Indian (Champagne, 8GB)

After using 7 Days Now there are four problem showing tentatively in Karborn A40 Indian 4G voLTE smartphone.....1.The PDF couldn't get visible after that were accessed it in offline from storage but can open only when it was accessed in online mode by any browser.from the storage while it was accessed only the black page came of it.Now the problem has gone automatically2.The ringtone can't changed as wishing....It shows the changing is processed but when any incoming call comes it become understandable3.The battery backup is not good for a hard and heavy users.4.Camera quality is not good But the phone performance is overall fast without hanging.But it should be mandatory to clearing catches and junk files or once rebooting per week to enhance the performance.

I am finding this phone excellent value for money, and the Nougat OS is great, has most of the smart features as far as I could tell. But initially, I had major problems during "unboxing" and thought it was a product defect, but as it turned out-- it was lack of sufficient detailed guidelines provided in the User Manual. E.g. it is not mentioned anywhere that the SIM cards need to be inserted whole, and based on product specs I assumed it's to be inserted micro=size and it could not read the card. But after I inserted the full card in sim slot, it worked beautifully. They should start preparing better video demo's for unboxing problems and post on youtube.

Very good for people and is great and handy

Very bad experience

Temporary usage phone... But still if all part are working then it's a good phone

The first time I ordered this phone, I had some issues with the sim slot and got the handset successfully replaced with the help of amazon customer care, full marks to the customer support. Talking about the phone, the battery backup is bad. If you're a heavy user, then stay away from this phone, but if you're not a heavy user then what's the point of buying a smartphone? This may be a decent buy for moderate users but not for heavy users.

Good mobile for a very reasonable rate. Latest android installed, and supports all kinds of 4G sims of all the networks. Don’t expect durability, and will have to take care of it a lot. Will not get the accessories in market also. But if for less price you want a 4G sim supporting mobile, then this is a good one.

Battery problem it's end in some minutes
