I Plan to Stick Around

It's a cross post from  xda.

 

I had a Lumia 800 before the 900 and one thing that surprise me was the screen at low brightness, the gray is kind of purple. On this thread I post some pictures:

For the LTE - Rogers needs to tweak their system settings for your account. They did so for me and I can tether with LTE, 3G (4G), and E with no issues....

For the purple screen - once again NOT the phone. Its a software issue related to the auto-dimming feature once it is at a certain brightness level. Nokia told me its aware of the issue. No ETA for a fix.

Can I ask a favour and have you share the case number? While you found someone at Rogers who knows how to tweak the settings, no one else there seems to.

 

Here is a quick video of the problem that puts a Samsung Focus beside the Lumia 900: http://www.youtube.com/watch?v=y4IfVdyuKq0&feature=colike


that video confirms its a software issue .. fix should be on the auto dimming feature ..

Purple screen is a hardware issue. The video you're showing looks like Auto is set on for Brightness, it's purple when the phone is on Low Brightness and fixes itself when it goes to medium.

 

If you google Nokia Purple you'll see other Nokia phones N9 for example exhibit the same problem. The problem seems to be related to Nokia's amoled technology. Some people have said that they don't experience the problem but they don't mention if they are running a black background as the problem only occurs with a black background and brightness set to manual/low. So returning your phone isn't going to help because this may be an issue with all phones at the moment. May be that only reason people are saying they don't experience the problem is because they have their phones set to a white background.

 

If Nokia fixes this through software, I'm going to guess they are going to just up the value on the LOW setting to a threshold where the issue doesn't occur.

So after my Rogers store finally got these back in stock I merily hoped into the store and had my hand at 7..count em 7..brand new shiny phones fully installed with the new firmware out of the box.

 

What did I find on every single one? By turning off auto and setting the phone to "low" brightness manually, every single phone had the purple issue. 

 

Now, a couple things come to mind. Firstly, this is obviously intentional from Nokia, i cant imagine how this would get missed on a simply quality inspection of the phone. Its clearly a different hue, and its not an advanced test by any means.

 

Secondly, on those who are reporting that they don't have the problem is that they simply dont know how to actually test for the problem in the first place. I've read posts that state that "turning on low/auto mode does not replicate the problem"..i dont think they realize that the low/medium/high settings are for manual only and do jack squat if you have auto turned on.

Not to mention that the problem only seems to occur if you have a dark background. Anyone who sets brightness to Manual/Low on a white background isn't going to see the problem.

 

I'm still going to guess that they are going to fix it by increasing the threshold for low brightness in a firmware. ie. if low = 25% and the problem doesn't occur at say 30% they will change low to 30% in the next update.

I've Been Here Awhile

This does NOT affect all 900's!  I happen to have two in front of me - my first one stopped being able to make calls (no call audio) and lost cell data after the firmware update (I know, weird...)

 

So I received my replacement yesterday - I can now make calls which is nice, but it has the purplish screen, and the vibrate rattle issue (my first phone had neither).

 

Not sure if I'm doing this right, but here's a photo proof - both set to low brightness, dark background, auto off:

so there is hope! lol

 

Lets face it though; if this isn't software fixable then that means mass recall.

John, thank you for the link. Despite these other articles, I think this is the first example of someone from Nokia acknowledging the problem. I've PM'd Kash my info. Hopefully others on this thread can take a minute and fire it over so they can get a sense for how widespread the problem is.

 

Not to mention all of the people out there that haven't noticed yet...

It's more apparent when you do the following. This is the best way for people to test for it.

 

Settings/Theme = Background DARK

Settings/Brightness = Automatically adjust OFF, Level LOW

Open Messaging (Not Email) App and click (+) button to type a message

 

Take a look at the keyboard which will be on a black screen and should be grey.

AT&T called their Nokia rep regarding this issue.  Nokia is scheduled to release an update by May 14th to address the purplish tint.  (They expect it to be released sooner, but promised by May 14th).  AT&T extended my 30 day window to allow me to return after may 14th if the software fix doesn't address the problem.  If your 30 day window is approaching I'd call AT&T to extend it.

Yup Its official.. Now lets pray we get this update on the same date as US Customers ..


Re: purplish screen

I could be wrong but I don't think they will be as urgent to release this fix since there is a workaround of leaving phone on medium. I think they are going to include this in their next update to fix this and all the other little bugs/tweaks as one big rollout.

At least they acknowledged they can fix it in software.

Re: purplish screen

Here is the phone statement from Nokia....

 

"Nokia has issued the following statement about the concerns expressed by some customers on this matter:  

 

We have been made aware of an issue creating a pinkish tint to the display on some Nokia Lumia 900 units. This is a result of a complex interaction between the device’s advanced software and chipset. However, we have identified and are currently working on a software update that will remedy the issue for a future update. In the meantime, affected customers can address the situation by going to “settings” and then “brightness” on their device. Once there, users should turn “automatically adjust” to “off” and set the level to “medium.” This will restore the color to normal tones. "

I just got the 3rd device and yeah, it's still there so I'm inclined to believe Nokia on this.

 

I feel bad that this wasn't isolated earlier so I could've avoided having to have Rogers send me 2 more of these.   I am greatful and very impressed with the great customer service in trying to make me happy though.

 

I'll be shipping my current one back and keeping the new cause re-shipping the 3rd one I think may cause chaos in their systems.

According to WPcentral.com today (Monday, May 7th), Nokia has found a way to fix the problem and should be sending out a patch.  (didn't say when, tho...)
