Well, honestly, I could not find any better word to describe my Nokia 2690 that I bought this April on my birthday. The phone was launched in mid April and I bought it on the 19th. I did not have any prior user reviews on the phone since it was newly launched. But I trusted Nokia to always deliver the best as they have done so for the past 10 years to the world, connecting people as they call it.
The phone was absolutely brilliant, very stylish looking, the sound was good,display clarity superb and what attracted me the most was the music player and the memory capacity of 8GB! I thought finally I've got THE phone I've been looking for.It worked very well for me till mid August when one fine day the display screen went hazy,hazier and then haziest. Finally it went blank. I tried switching it off and then switching it on again. I tried it for a long time. Then a friend suggested me to call and see if the sound was okay. I tried and to my horror discovered that I could hear the person on the other end, no matter who called,me or the other person but the person on the other end could not hear me. There was a problem with the microphone I thought. I kept it switched off for a long time and then when I switched it on,the display was normal. I sent it to the service center, NOKIA CARE. They did some "job" and gave it back.It was working okay then.Again within a few days the same problem cropped up.I got it to another nokia care shop and they said the phone had trapped moisture and so the warranty would no longer be responsible for it.I wonder how my phone could trap moisture! I do not swim/take a bath/drench in the rains with it. The only solution that came up to my mind was that may be the phone is hygroscopic! I got my phone repaired for Rs 165 and then it worked quite well for a few weeks.Again after many days the same problem has cropped up today again. I am disgusted with Nokia. I have heard quite a few acquaintances complaining of similar problems and every time the phone is taken to Nokia Care, they say "moisture". I wonder what material Nokia is now using these days to make their phones for they are so hygroscopic! I think Nokia should change the material, IMMEDIATELY.  I am pissed off...
