Blue tint on OLED screen when phone is cold

[Guest agreenjesus]

I don't like it.

[Guest Weissauchnicht]

I had the same problem some weeks ago- the screen was at cold temperatures blue from the top of my screen. Now I haven't this problem anymore. I think it was charger. I couldn't charge my blade with the original charger because I'm from Germany. The charger I used previously was from eBay. But for some weeks I'm using the charger of my second phone (Motorola flipout 5.1v 850ma) also for my blade. The charger charged faster and I had no problems with the touch screen while charging. The blue lines didn't disappeared instantly but it was getting lesser and lesser. For 1-2 weeks I haven't seen the blue lines again although the device was sometimes really cold. Maybe it wasn't the charger and I had only luck but I think it's worse a try if not using the original charger.

Woke up this morning to this.

Can't seem to find the original Orange SIM that came with it, anyone had a successful replacement without a SIM?

Nope. The moment I mention I'm no longer with orange the helpful(ish) english call centres transfer me straight to india, who seem to have no idea that according to UK trading standards it's the traders responsibility to replace the phone, regardless of its network.

If you need a sim, try here: http://freesim.orange.co.uk/ (afaik sims become inactive after 1 month of disuse, so you probably need a new one anyway)

It takes a few days for delivery, but doesn't cost anything.

I still haven't actually replaced mine. When my orange sim arrived the whole Gen1/Gen2 thing had just popped up, so I thought I'd wait for that to be resolved, then I went home from uni for easter, but since my orange address is my uni address, can't get a replacement.

Plus I still don't want to loose the OLED screen. I'm tempted to just buy a new one and try to fix mine.

I rang customer services and just let it ask for my number a bunch of times until it put me through to a callcentre and then got the indian bloke to give me my Orange number using the Sim number on the box. I then rang customer services again and gave them my orange number and a scottish lady said they are sending out a new handset tomorrow.

Now debating selling the new handset alongside my old Nokia touchscreen and putting it towards the HTC Desire that is only £250 at phones4u and possibly cheaper as a payg upgrade instore.

I got this problem some days ago and its really annoying, but the thing is I imported my phone so returning it for a replacement would be very difficult and simply not worth it. So did anyone manage to figure out why this problem happens and is it fixable? I thought I would keep the temperature up somehow, one idea was putting a few layers of tin foil in the back, but haven't played with this yet. Also a few days before this happened I stopped using the sock that came in the box, so the phone was out most of the time. Maybe the change in average temperature caused this or something related to the fact that before it was in the sock most of the time and then not...

If I figure anything out I'll post it here, and I'd appreciate if anyone would try and solve the problem, rather than having the phone replaced, after all, you would lose tho OLED, which seems to be the only type of a screen that can be affected by this.

It's getting summer.. so it's getting better :)

[Guest Denzo]

Its just upsetting to see that blueish third of the screen every morning and It will have to be really hot for it to disappear. On simi clock widget there is a battery info thingy and by its measurements the blue flicker appears when battery temperature is under 27 degrees Celsius. I always charged my phone via computer, cause the chargers jack doesn't fit. I wonder if anyone besides Weissauchnicht had luck fixing this by using a different charger? I tried googleing the problem in hopes to find other cases of this maybe on other OLED phones, but no luck.

[Guest nobug]

I had an equally looking issue on my laptop screen. The problem was a loose connection.

It was not blue. But also only part of the screen and flickering.

Maybe it is the display connector. You can see it on these pictures

[Guest harmohn]

Out of curiosity, have any of you guys tried playing around with the rendering options in CM settings (CM7) to see how this effects the issue?

Does sound like a loose connection on the display mind; ie. as the device warms up, the connector would get a better contact if loose.

Maybe!

[Guest Denzo]

Seems like a reasonable assumption to me. I might take it to a shop and see if they can get it fixed, if it's just a loose connection, it shouldn't be too expensive. There was talk puting the phone in a oven, but I'm not ready to do it just yet. As for the rendering settings in CM7 they don't do a thing and the problem seems to be presistant, regardless of what ROM you are using. Tho you Nobug said in previous post reverting to JJ helped you... I will try changing roms too.

This may have been because the installation warmed the phone :mellow:

Maybe we should try to start in recovery, when the blue tint problem occurs,

and see if it's also there.

[Guest Gryphonic]

The blue tint is present whenever the screen is on - In recovery, bootloader, etc, which points even more to a bad connection, however there certainly did seem to be some connection between the tint and what rom was running.

If we assume the rom has nothing to do with it, a poor connection fits the bill perfectly, even accounting for the temperature dependence (warping/expansion).

[Guest Denzo]

I believe it is purely a hardware thing when the phone is cold the tint appears. I think the differences when using different rom, are likely due to different way the rom uses hardware, so some roms use more resources and keep the phone warmer for better part of the time, while others might use less and thus keep it cold. On CM7 when the phone is in deep sleep for a while its quite cold and the tint is there when I wake it up. Maybe because it under-clocks the proc. Thats just my assumption, a workaround to this problem could be finding a way to keep your phone always above certain temperature, but its not a solution. We need a solution.

Any news?

Has anybody tried to fix it at the display connector?

[Guest drobson67]

Hi, If anyone is planning to return their phones to Orange make sure its before six months from purchase as they dont do a twelve month standard warrenty and will winge about replacing it, my zte blade has had the blue tint flicker now for 5 months and has steadly got worse even though the temperature has been getting warmer, have tried several roms and each one is about the same, I dont think it makes any difference and when the problem first started I had the original stock rom installed and the phone was never tinkered with. I rang Orange today explaining the fault and they agreed straight away to send a new one out by 24 hour courier to swap old for new without seeing the fault first hand, I think they are well aware of this and is a very common problem. My phone has an oled screen and it will be interesting to see whether this problem is unique to oled rather than tft which I believe is a newer type of screen.

[Guest Gryphonic]

I took apart my phone yesterday (hopefully without voiding the warranty) to try and fix it, but no luck. The ribbon cables weren't very accessible without separating the two PCBs and the screen, and I didn't want to fiddle with the internals too much, as last time I did that to a gadget (Zune 80) I bricked it. What I did do was wobble the connections (not that i could actually feel any movement there) and made sure the ribbon cable retention clips were properly in place.

Sorry guys, but i didn't want to try anything else for fear of bricking it.

[Guest Denzo]

Sad to hear your efforts were to no avail. I will take the phone to a repair shop, when I find one that can do it cheaply, if it can even be done. If not I do not know what I will do. How much do you think one would be willing to pay for this faulty phone, soon to be out of warranty? How much could be earned selling it's parts, like digitizer, battery, back cover, sd card... what else is there?

[Guest nobug]

There is another thread with the same problem. There is another possible cause of the issue:

"my digitizer broke, so i went and got a replacement panel and when i went to the shop to pick it up they told me my OLED panel underneath had cracked aswell , the blue flickering on the screen means you have a clacked OLED/LCD panel beneath and the reason it goes back to normal when hot it because the glass touches and goes back together for a little while"

[Guest Denzo]

yea I read that topic and there is another one on the same problem

http://android.modaco.com/content/zte-blad...sco-gone-wierd/

but the cracked panel thing seems a bit weird to me, because we have the same problem, and that is the blue thing on the upper third of the screen, there are screenshots in both topics and my blue third is exactly the same as the pics in the aforementioned topics show. Does that mean we have the crack on the exact same spot? or as long as there is a crack that is how it is going to manifest. Also only one poster claims the cracked panel is the cause. Is there any one else who had their phone repaired and they told him cracked panel is the case? This thing is making me go crazy, I think Im just gonna lose it and put my phone in the oven and see what happens...

edit...

oh and just wanted to say that I haven't droped my phone or treated it roughly in any way, so I do not know how could the panel get cracked..

Has anybody finished the replacement procedure?

Is the new phone a OLED or an LCD one?
