john, 03 Mar 2011hi maverick just wanted to know your input about
the AMOLED issue with most c7 and n8 phones.... moreHi John,
I'm glad you brought up this issue, I wanted to discuss this myself having heard and read a lot about it, and i'm glad ShanNan shared his feedback too.
I'll give you my experience on this..this issue seems to affect N8's and C7's, and not so much the newer C6-01 which uses a different screen technology.
The main symptoms, and issue can be read at this link for users who are not aware of it : http://www.allaboutsymbian.com/news/item/12604_Defective_screens_found_in_som.php
The main issue as you pointed out is a reddish-purplish discolouration of some dark grey/black tones. Seems to be fairly common among N8 and C7 displays. Will give you my feed back on this :
I've had the C7 for two and a half months now. I dont know whether I've had the symptoms from the beginning, but about a month ago (when i started using power saving mode regularly for my device, which kept the display brightness to minimum at all times), I noticed the top half of the analog clock on the unlock screen to be reddish.(I never saw it purple on my device as in the pics in the link above). I read from forums that the video playing would also be affected in dark scenes and so I checked that out, I found that at low brightness levels, the dark areas in videos (movies i downloaded)seemed to be pixellated and the entire video seemed to have a washed out effect. Thinking that it may be an issue with the video player, I installed an alternative player, Smartmovie, but got the same results. I then downloaded the test images (in the link above) and checked them, and it displayed fine..no purplish tint or hue, just black and gray.
After experimenting quite a bit on my device, I have come to the following conclusions, atleast for my device..
1)The issue seems to be more pronounced at low or minimum brightness levels, I have not noticed any reddish/purplish hue on either my clock or videos/images on a brightness setting of more than medium.
2)Viewing the display in bright light, which forces the light sensor to increase display brightness, even at low brightness levels, completely eliminates the problem.
3) The issue is more pronounced in videos having dark scenes with a mix of grays/blacks, esp when the scene changes from dark to light.
4) I've played the same video file concurrently on my N900, Galaxy S and C7..the C7's display seems to give a "warm" tone to the video..ie reds and pinks appear deeper, flesh tones (for example someone's face) looks more pink (or healthy lol).
Most users who have the purple problem or distortion of the images (try them from the link above..gradient and tone), have contacted Nokia Care, and seem to have got the same response as ShanNan, ie some devices have been changed but the problem (or symptom) seems to be near universal.
I can only assume that its either a display issue/normal phenomenon of the AMOLED with a combination of its high contrast and low brightness setting, or a video driver problem, or maybe an inherent problem with the calibration of the display ( I feel Nokia engineers may have tweaked up the contrast and temperature of the display, making colors more "warm").
If its a video driver or calibration issue, I suppose it can be fixed in a future firmware upgrade. Nokia is quiet on the issue, but the response ShanNan received seems to indicate they are taking it seriously (it also indicates they dont know what's causing it, yet lol). What I also don't know is whether this issue will have any long term effects on the device, which I dont think is likely. My videos show just fine if my display brightness levels are medium or above. That said, I dont think a device like this or the N8 should have an issue at ANY brightness level..Thumbs down to Nokia on that.
My suggestion would be that if you have a major case of the "purples", then do contact your Nokia Care Centre. All your devices will be under warranty and they may replace your device if they find it faulty. However if your symptoms are not too severe or sound like the one I have, then hold on and wait for the official Nokia explanation and perhaps an Update which will fix it. I'm interested in knowing how many people have the issue to the point of it degrading their video watching experience..all of you please post your experiences here. Cheers.
Andrei, 03 Mar 2011hi Maverick...this a nice phone...its features are as stated in the tech specs..i just got it ... moreHi Andrei,
It seems your phone is missing these apps, and they are integral. All phones come with them installed. What I'd suggest is that you backup your phone (you can do that from file manager-Backup) or backup using OVI suite on your Pc, and then re-install PR 1.1 using Ovi Suite. That should fix it. Hope it works for you, Cheers.
fred, 03 Mar 2011hi mavrick, pls i want to know if i can download a payed games at ovi store without the credit... moreTo further clarify, You wont be able to use the prepaid credit in your phone. You need either a credit or debit card to do that, or the card details of someone (like a friend or relative who will allow you)to make purchases.
fred, 03 Mar 2011hi mavrick, pls i want to know if i can download a payed games at ovi store without the credit... moreHi Fred,
As far as I know, you will be able to transact on ovi store using a prepaid/debit card. However, it also depends on your bank. Some banks dont allow debit transactions online without a special PIN/one time password that they usually send by sms to you when u conduct the transaction. I'd suggest you check with the bank if your card can be used online first, and if it is, there should be no problem. Another thing I'd suggest is not to link the card with your ovi account as its a debit card, just put in the details everytime you make a purchase. It may be more cumbersome, put its more secure. Good Luck.
AnonD-2816, 03 Mar 2011thanks again MAVERICK.. i must say that ur knowledge about mobiles is quite good. today m pur... moreYou can charge your phone normally while it is on and online.. no need to switch it off. The old rule of charging is to fully charge and let your battery drop to one to two bars left and then again fully charge, this is less important for new batteries but seems to work well for me. Be aware that your battery life will seem short the first few weeks you have the phone.. it will reach peak performance only after that. Charge your battery to full the first time you use it and dont leave the charger connected unnecessarily once the battery is fully charged.
AnonD-2816, 04 Mar 2011hiii everyone....one more question i would like to ask, that after buying it i have to charge ... moreFor the first time you may switch off and charge for minimum 3 hours. And the subsequent charges as per your convenience

john, 03 Mar 2011hi maverick just wanted to know your input about
the AMOLED issue with most c7 and n8 phones.... morebuddy i have the same prob with my phone..
i visited Nokia Care but they said they were not aware of it and said it was in every handset (including da piece they showed me) and), they said it was normal.
i then sent a complaint directly to Nokia India via email. In a weeks time i got a call from Nokia India, they told me to go to the same Nokia Care centre but this time they would have someone to personally look into the issue.
so i went to the centre, the manager of the centre himself came to look at the issue, he accepted that something was not right in the screen and said that he could try and change the display, which they did.
But the new display has the same color defect.
I guess all the Indian handsets have that defect. u'll have to live with it.

How is the GPS feature in this mobile? I live in Riyadh, Saudi Arabia. Do I Need to download any street maps to this mobile from OVI store? Do I need to be on the GPRS while on navigation mode? Or does it works just like a typical GPS gadget namely Magellan or Garmin using the satellite signals. Need your help asap.
hi maverick just wanted to know your input about
the AMOLED issue with most c7 and n8 phones..
its where the dark gray colors tend to be purple.
is it a hardware defect? or can it be fixed with software update in the future? unfortunately, mine has it. I've had my c7 for almost 4 months and everything is ok aside from that issue.does your display show this kind of discoloration?you can check it if you set your clock to analog, lock your screen, then press the menu button..if half of the clock is purple, we have the same issue.please reply thanks.
