Blue tint on OLED screen when phone is cold

[Guest Gryphonic]

My screen (OLED) has a blue tint (not unlike the blue tint you got on a TFT phone with an OLED kernel) covering the top third of the screen when the phone is physically cold.

This started about a month ago, directly after installing the JJ RLS9 rom. I first noticed it when the alarm went off the next morning, but it disappeared after about a minute. After a few days i worked out that the tint appeared when the phone was cold - ie, had been sitting on my desk/bedside table. It gradually got worse, with the phone needing to be warmer and warmer before the tint would vanish. The tint was visible from boot, not just when android os was running.

Tonight I loaded the Cyanogenmod CM7 rom, and the tint is now constant.

Before tonight i assumed it was purely hardware (maybe a hairline crack in a solder joint), but the correlation with the rom changes has me wondering... although I can't see how software could make anything temperature dependent. When i thought it was hardware, i was considering dismantling it and assuming i could get all the plastic off the main boards, baking it to repair any solder joints, but that has a pretty high chance of bricking it and i'm not even sure its hardware anymore.

The only other case of this i can find is at androidforums, and the op didn't get any useful replies.

Anyone had the same or have any ideas?

Heres what it looks like currently (image tags aren't working for some reason)

Thanks.

Same problem here had to get a new replacement as no hope......and I cam to the same conclution

[Guest Gryphonic]

Was yours OLED too? and did they give you any idea what was wrong when you returned it? (ok, its orange, so i know the answer to that, but still.)

Did yours just start independently, or did it appear with a rom change?

I've never heard of this before... anyone else experienced it? If it's a bad joint somewhere i reckon its likely fixable... not sure i really want to completely void the warranty though. If it does have something to do with rom changes though, its going back to orange :huh:

Also i don't really want to return it and get a TFT version... I really like the oled screen :/

yea mine was oled .....no they just said ill get one next morning but was tft but don't really see the difference I mean they both have same functionality...

and my conclusions where the same as you and another guy who had same problem its fine when hot but as soon as it gets cold......bammm the blue appears mine started to flicker first then it just stayed after i rebooted it but is all good now as my tft hasn't had any problems.

[Guest Gryphonic]

Just restored a backup (CM7 isn't quite stable enough yet) and the blue tint now covers 2/3 of the screen. I'd guess this isn't hardware realated :huh:

I'd better find out what i need to to do to it to return it. :/

Thanks.

If you need to return it you can load a stock Orange rom (sebastian404 has them on his web site, hunt round the forum for it). These roms also have the stock image and recovery partitions, so once loaded, and rebooted, it will be as out of the box. Make sure you select the version you had originally (not that i think Orange will notice, but you never know !). The only thing I've never found an answer for is whether the phone gets re-locked to Orange, otherwise I've never seen a method to re-lock it.

Good luck !

I was planning to do the stock TPT, which should lock it too. Saves setting up fastboot again. (wiped my netbook sine installing clockwork)

My only fear with that is thet it will be a different version, as mine was one of the early oled ones... I doubt they'll notice too though.

My only other fear is that i left it in my pocket with a blue marker pen and the pens lid fell off - its now got a blue behind... but theres no way it can affect the phones operation.

Sorry for the double post...

I used TPT to get it back to stock, and the blue tint all but disappeared. It still appears when the phone has been left on the table for a few hours, but the rest of the time its absent. also it only ever covers the top 1/3 now, rather than 2/3rds.

As it is still there, I tried to return the phone anyway, but as I've moved away from orange they're refusing to honour their warranty and keep telling me to contact the manufacturer. As far as i can tell from googling, its still oranges responsibility to replace the phone, as they are the trader that sold it, regardless of which network its on.

At the moment I've ordered a free orange sim, so i can return it on an orange number. In the mean time, has anyone got any handy advice for dealing with orange support?

Yes it's definitely Orange's responsibility even if you unlocked the phone. I'd contact Trading Standards first. They're generally pretty useless but they're free so worth a shot.

If that doesn't work then I'd write a letter to Orange's head office (sent by recorded delivery) threatening to sue them in your local small claims court. Once they realise you're serious they'll back down pretty quickly.

Hi,

Ive had the same blue screen flickering on the blade, sometimes half screen sometimes full and disappears once the phone warms up, seemed to happen when I was outside in the cold that was the give away, I havent changed the origional stock rom from new and have only rooted via universal androot and used some overclocking app, but never done anything too drastic for fear of bricking the phone. I guess the problem is probably hardware related as temperature effects electronic components not software but no totally sure. Its under warranty and Im considering putting the orange sim back in and returning it to the orange shop for repair or replacement, its currently unlocked and on giffgaff.

Hope this info helps,

Damian.

That was my thought, as how could anything software change with physical temperature, but it certainly seems to have something to do with the ROMs, or loading the roms anyway. It certainly seems linked, as it appeared when I loaded JJ 2.2, got a lot worse when I loaded CM7 RC1, then nearly fixed itself when I did a TPT back to stock.

I really don't understand it :/

I might have another go at orange customer support tomorrow... University is piling on work at though, so not sure i have time to go through trading standards. Dropping an orange sim in there sounds easier. All the same, thanks for the clarification g-rasshopper, I hope I don't have to go that far :D

i have toasted my phone last week

i have called orange (france) and didn't have any problem to get a new one

they have only asked for two things

1) my orange's phone number (my old number in fact i'm not with orange now)

2) the phone's imei

they make the exchange under 48 hours (except week end)

[Guest Gryphonic]

sounds good.

My only problem is I don't have an orange number... geting a sim in the post though :D

[Guest Stevvie]

I too seem to get this blue flickering when the phone is colder than 18-19 Celsius. when the phone is 20+ I never see this. Also appeared about an hour or two AFTER updating rom from FLB r10b to FLB r11. I might try and restore my nand backup and see if that changes.

[Guest aejt]

Today this started happening to me as well. It flickers less when warmed up, but it still flickers pretty much.

Using FLB-froyo r9b right now. Going to try installing Swedish Spring now, doubting it'll work, but giving it a chance.

I can't really contact orange if this doesn't work, as I live in Sweden, but it is bought in the UK. If I can't find any solution within a week or so, I might try baking it.

Edit: Warmed it up more, now it's completely gone. Still trying out the other rom though.

Edit 2: Still happens with the new rom. I really doubt it has anything to do with the roms, as it started happening to me one month after I installed FLB r9b.

[Guest Gryphonic]

Sorry to hear it.

It seems this is getting to be quite a common problem...

If you have a go at baking it, let me know :D

I would like to take mine apart and try to fix it, but if I can't then i can't return it any more :/ i know they're not that expensive, but its still more money than I want to lose :(

I'm still waiting on the orange sim to arrive so i can return it... Keep us updated :D

I don't think that backups/ROM changes do anything for it. It certainly seemed to get worse after ROM changes, but I'm not sure they made it better, as my TPT to stock coincided with the weather improving a lot, so it might just be better due to higher ambient temperatures. And i still don't understand how temperature changes could affect software at all.

[Guest jt!]

Hey all,

My girlfriends blade has this issue now, only started happening after i flashed CM7 so i initially thought it was related to that..... then i remembered i dropped her phone recently. it was quite a big knock so i think that was the cause.

jt.

[Guest Michealtbh]

I know the Blade is a relatively cheap phone, but I think its worth getting it insured. Most places will do it for around £2 a month which is nothing really

[Guest jameslewis]

I had this too last week on holiday, went to bed and left my phone on a cold floor next to the bed in dimmed clock mode on the charger, woke up to the room flashing brightly, noticing my phone flashing like crazy!!

The next day it stopped, but then it returned for the rest of the week and now constant even when phone warm. The top third of the screen flashes a sort of blue tint on the OLED screen.

I had FLB-G2 on my phone, restored it to orange stock rom and it was still the same. Before this I had been running 2.2 rom for ages with no issue.

Took the phone back to my orange store yesterday, they said to call orange and courier will collect so they are going to swap it today. I expect I'll get a TFT one now, but I got an HTC desire yesterday (£229 at phones4u at the moment http://www.hotukdeals.com/deals/pay-go-net...hones-4u/880870 ) so the blade can be a spare, or I may sell it to help pay for the new one!!

I have exactly same problem - my phone has begun to flicker but I live far from UK so the exchange would be very complicated.

Maybe overclocking the phone would help a bit (temperature of the phone should raise), but it is not very good solution as it will drain the battery much faster...

[Guest nobug]

I have seen similar issues: When overclocking graphic cards.

This problem might be a software-hardware combination.

For me this startet with a JJ firmware. Now on CM7 it's more

often. And can often be worked around by locking screen, rest

for a few seconds (+5) and go back.

Might be an overclocker problem. Have you all overclocked

your phone?

Mine was running with 691MHz max for a long time.

[Guest Gryphonic]

I've never overclocked my phone, and unfortunately it doesn't disappear if I leave my phone for a bit.

If it was an overclocking problem it would appear when the phone had warmed up and the hardware was overheating rather than when it was cold, as it does on mine.

Also it still happens with the stock rom, so it's not anything to do with software.

[Guest nobug]

so it's not anything to do with software.

I reinstalled an old JJ backup from february. NO blue!!! (EDIT: Maybe this was because phone was getting warm during installation.)

(Same overclocking, same governor (ondemand))

Reverted to CM7... blue :D

Search around the forums for Blade unlock.apk and that will let you "reset the lock attempts" (lock it back to orange only sim cards)

It seems we have different causes then, as when I restored the first backup image ever took, of the stock 2.1 there was barely any change. It did seem to decrease a bit but by no means went away.

@androidlover, thanks :D
