White mt4g made in china, bad screen
[myTouch 4G General] tellairai:
TMobile sent me a Warranty exchange one. Its a black MT4G from China with 2.21 on it. It was brand new still and not a refurb also.
[myTouch 4G General] charnsingh_online:
I bought a mt4g made in Taiwan didnt receive yet, wat chances are that it will be one with a good screen. It was bought like a week and a half ago
[myTouch 4G General] Amac1222:
Just ordered my warranty exchange phone through an online rep. Had no issues with it and should be receiving mine within 7 business days. I asked about going into a retail store and she told me that she couldn't guarantee they could do a warranty exchange. Also I noticed in the prompt on stuff not covered by the warranty it dealt with things dealing with the screen itself. Nothing was said about the phone being rooted or not. However, I'm still going to unroot my device to save my a$$. Praying I get the good screen! Mine's a black one, which have been going fast, so hopefully it's the good screen!

Guys!!!! I'm like a little happy kid on Chirstmas right now

Ok, I got my replacement today, really unexpected as I've tried tracking with refrence number and didn't find anything and was expecting it sometime later this week.

But I opened it open, first looked at the back, and it said Taiwan... Ok I have a 50/50 shot of getting this right, powered it up and BAMMM!!!

Couldn't notice the difference but then I looked at it from different odd angles and yes! Downloaded Terminal emulator and vertifed its a type 2 panel!!!!

Phone looks to be brand new, except for a small ding in the back where the sliver thing is above the flash.

FFC centered and all, it's a white one too.

I'll be posting pictures in a bit, charging the camera right now and unrooting mine while it's charging.

THANK YOU GUYS!!! for bringing this up to my attention and every MT4G owners all around.
[myTouch 4G General] bobsbbq:
Very glad you got a good one, and glad this thread might have helped you.

I just wish the bigger blogs would have picked up this story. News tips were sent to numerous ones like engadget, TMO-News etc. But it seems they are scared to put it out.

But when the Nexus S was just rumored to having restarts it make news?
[myTouch 4G General] m00nshake:
I got a Nexus S and went through two replacements before I got one that worked the way it was supposed to. But coming from a Vibrant, I couldn't get over the fact that I was still buying another Samsung phone. My first Android was a G1 and it was great so I wanted to go back to an HTC phone. I did my research and got a MT4G.

Although my first one had the bad display and I had to switch it out at the retail store for one with a good display, I really like this phone and am glad that I switched back to an HTC device.
[myTouch 4G General] r1csh4w:
accidently voted that I had good screen. Definitely have the bad screen. Too bad since I got mine first day. =(
[myTouch 4G General] xdviper:
Here's some of the pictures that I promised.

I'm sure you guys will be able to tell which screen is which. :p But I also placed the "defective" sticker under the phone to help you notice if you're new to it.

But yes, there is clearly a difference between the two and I'm still getting used to the new colors and it's just wonderful.

Also, the replacement came from Fort Worth TX. The Screens are on highest brightness and the new one does have the screen protector from the factory on it but it shouldn't make a difference at all.

Is this an AMOLED v. S-LCD issue, not "good" v. "bad"?

The differences in characteristics of screens called "good" and "bad" sound like the differences between S-LCD and AMOLED screens.

The differences between screens were described in this forum as follows:

"a more rich color and better contrast display and with better viewing from angles. The majority of the ones shipped have the less than perfect display which has less contrast and the colors, white are washed out and blacks are not true dark blacks. And the inferior display has trouble with viewing angles not being clear and has a washed out look, the launcher bar is gray instead of black etc."

These differences seem much like differences between AMOLED and S-LCD screens, as in the HTC Desire:

http://www.engadget.com/2010/09/13/spot-the-difference-htc-desires-slcd-versus-amoled/

On the other hand, TMobile states on its site that the MT4g has a "gorgeous, high-resolution 3.8-inch LCD screen" and HTC claims a "3.8 inch TFT-LCD touch-sensitive screen with 480 X 800 WVGA resolution." An LCD screen, according to Engadget, has better resolution than an AMOLED screen.

If it were a question of AMOLED vs. LCD it would not be clear whether one screen or the other is "good" or "bad" because that depends on all the circumstances to be considered - contrast vs. sharpness, for example. AMOLED and LCD screens differ in optimum viewing angle, contrast, color saturation, power consumption, and resolution. For any particular person "good" or "bad" would depend on a balance of all these factors. If it turns out to be a question of AMOLED vs. LCD, a Rush To Replace on the basis of "quality" may be ill-founded. If all MT4g screens are LCD screens, though, some might be "better" than others.

Is there a way to tell whether this is an AMOLED vs. LCD issue - by comparing at pixel placement and density under magnification, for example?
[myTouch 4G General] cthulion:
I think you're confused...there's no AMOLED displays on any Mytouch 4G, just different makes of LCD - one from Sharp (bad) and one from Sony.
[myTouch 4G General] 808HD2:
Ok I got this bad dilema :( I got a replacement comming in, and while I was cleaning the phone the void sticker came off and I put it back on.. I dunno whay should I do? My screen is good but having alittle issue.. Can I return the replacement phone?!
[myTouch 4G General] charnsingh_online:
try sticking it back in using glue
[myTouch 4G General] Chedderknight:
Had a question, Just got a replacement order in, should be here in a week, how did some of you get multiple replacements in before getting the *good* screen? I dont think my chances of getting it right on the first try are that great.
[myTouch 4G General] cl2eep:
I too had the Bad screen and a crooked FFC on a 1st gen red MT4g. I pre-ordered and by the time this thread came around my 14 days was up. I was, however, able to call T-Mobile and say my FFC was noticeably crooked. It took a couple of tries recycling replacement devices, but I'm happy to say I now have a red MT4g w/ a straight ffc and a good screen. Don't settle for a bad device just because your 14 days are up!
[myTouch 4G General] chrisjs81:
For warranty exchanges just send back the replacement in the same box and contact t mobile again, telling them the replacement had some problem so you need another replacement.
[myTouch 4G General] TeeJay3800:
Is it possible to have a good display while still having your LCD panel identified as "type 1"? I've compared mine to several friend's MT4Gs and their displays all have the noticeable characteristics of the bad display mentioned in this thread. By comparison, mine looks awesome, and doesn't have the viewing angle problem or the washed out colors. Yet when I type "demsg" into terminal, it says I have the type 1 panel.
[myTouch 4G General] xdviper:
I gotta say it hasn't been 24 hours yet since I got the replacement and already I'm still getting used to the new colors on the phone. I've had the previous phone for less than a month, but there clearly is a big difference. The Facebook app colors have more depth to them and have such a solid color to it, even the gingerbread keyboard looks different. Some things you won't realize it but wow there is a big difference in colors of the phone.

Its like the darker colors on the phone look way better. Not so much for the lighter colors.
[myTouch 4G General] Phateless:
The first time I used the navi while the phone was sitting in the vent-mount cradle in the car was when I was really blown away. Even the slightest angle washed out the old one but the new one, the colors just looked incredible! Especially in the dark.
[myTouch 4G General] el_smurfo:
Just picked one up. Made in China. Screen seems good. dmesg shows panel type 2. FFC centered as well.
[myTouch 4G General] Phateless:
There are several pages of output. Scroll all the way up to the top. It's line 14 or 15 and it's something like

<7>00000000 tag panel parsing panel type = 2
[myTouch 4G General] el_smurfo:
Finally tried "restart phone" and was able to find panel type 2. Powering off didn't seem to work...weird.
[myTouch 4G General] Phateless:
Ah, that's because you have fast boot enabled. The MT4G fast boot is not a true shutdown - it's a hibernation, so it doesn't actually clear memory.

It's good habit to do a proper restart on your phone at least daily.
[myTouch 4G General] theclueless:
tag panel parsing panel type = 2

nice screen, like it better than samoled
[myTouch 4G General] el_smurfo:
I wondered why it "booted" so fast and was also confused by the "fast boot" menu item in the applications menu as fastboot means something entirely different to me after rooting so many phones.
[myTouch 4G General] Starbuz:
Got mine last nite from the local classifieds since I wasn't eligible for full upgrade price and got it cheaper than the 2yr extension upgrade.

It's white made in Taiwan, dmesg returned panel type=2 so I'm very happy with my purchase, the phone is awesome. :cool:
[myTouch 4G General] Phateless:
Yeah I hear you. Wish they would've called it quick boot or something.
[myTouch 4G General] ArcticWolf91:
Great things just keep getting better for me. So after two replacements both with the bad screen, UPS has now lost the phone I shipped back to T-Mobile. At this point I don't know what's going to happen. It's been a while already and T-Mobile still has not contacted us about anything, and I'm afraid to ask what's going to happen... I just hope that they don't end up charging me $450 for the phone because I literally don't have that money right now. This sucks, and I still have a bad screen. :(
[myTouch 4G General] mgymnop:
I like it better too had an N1 and a NS and I am not such a big fan of (S)AMOLED.
[myTouch 4G General] bobsbbq:
As long as you have the tracking number and can prove it was not delivered then it's UPS liability. Well depending on what they say the default value is. Where does the UPS tracking show the last scan?

Sorry to hear about all the trouble. I hope you will eventually get a good one and enjoy it as much as I have.
[myTouch 4G General] bobsbbq:
A good sign T-Mobile is addressing the bad screen issue finally

Wow this is great news!

Well it looks like we may have reached a turning point on this issue if this information above is true.

Maybe they are actually telling the reps to find and replace all the bad screens. I want to thank btbuck1 and everyone in the beginning stages of this problem that helped us push the issue and didn't quit when ridiculed by a few in the beginning.

I would also like to thank the many other members who have been very helpful in this thread. That have answered questions and helped other members with this issue. Too many to list but you know who you are.

Thank You
[myTouch 4G General] ArcticWolf91:
Thanks Bob. The last known location is Mesquite, Texas, which is where it was being shipped to. I shipped the phone on the 7th, so it has been a while. Like I said T-Mobile has not yet contacted us, so I'm hoping that they saw that I shipped it and are now working with UPS to find it, leaving me out of the whole situation. I just dont want to end up paying for the phone somehow.
[myTouch 4G General] cthulion:
T-mo can be a mess with this, I had to call over 10 times to be credited for a phone I returned 2 months ago...I returned 2 phones, they got both at the same time and only credited me for 1...still not resolved.

My only advice is call and be on top of it, they can and will charge you for every little thing they can.
[myTouch 4G General] rich2thad:
ok so, knowing i had the bad screen, system info lcd type sh co watever, watever, i never botherd to look where mine was made, today, i roll over frab my box today which o fortunately never tossed, and mine was made IN CHINA wthekk, is this just bad luck or have i read wrong thinkn china made the good ones
[myTouch 4G General] bobsbbq:
There are some bad ones from China as well. The odds are just better at the moment a made in china will have a good screen.
[myTouch 4G General] rich2thad:
ooh i see, ugh i want a good screen but ive had my phone for around 3months and have.been.too lazy to unroot and call tmobile being unsure if they will even be willing to send me another
[myTouch 4G General] Drzfr3shboialex:
I got the good display at least I believe and this is my 1st one plum version I got it 2-3 weeks ago, abd thankfully i don't have any problems
[myTouch 4G General] bobsbbq:
If you want to know for sure run the terminal command dmesg and you will know.
[myTouch 4G General] btek:
What did you say to them?! I never noticed a difference untill my fiance got her phone today and it was AMAZING compared to mine..so I started the research and found this.....called t-mobile and the rep litterally told me I have to deal with it because its not a warrenty issue that my screen blows... anyone have any ideas what I can do..... I didnt care before I knew the difference!...but now seeing hers .. I want the better screen!!
[myTouch 4G General] Phateless:
Call back and talk to someone else. At the prompt say MYTOUCH SPECIALIST.
[myTouch 4G General] bobsbbq:
You probably just got a bad rep. Try again. This time when the automated attendant comes on say cancel. This will get you to a higher lever of support called customer loyalty and retentions. Be nice but firm. Tell them that your display is all washed out and you can hardly see it. You have it side by side with your finance's and hers is not washed out and the colors are good and the screen can easily be seen from slight angles without problem. See where this goes. Just tell them all you want is what you paid for, a good phone. And only if necessary direct them to their own forum site, HTC forum site, and here.

It really is luck of the draw on who you get on the phone. Some are aware of the issue some are not.

Just keep trying, don't give up.

Good luck
[myTouch 4G General] bobsbbq:
Wow I did not even know they had a MT4G specialist. I guess this might be as good as retentions, but not sure.
[myTouch 4G General] cthulion:
Call again and ask for tech support, mention that you have two to compare, that you did your research and there's plenty of documentation about it on T-mo user's forum.

That did it for me.

Others had to mention/make up other issues they might or might not be having such as crooked FFC and creaking buttons. It all depends on who you get on the other end of the line, and about how nice, calm but assertive you are.

The rep told me they would send a bare replacement unit but I got a brand new one in sealed retail box.

Got a decent one on my 4th attempt, so you might be in for a ride.
[myTouch 4G General] Phateless:
I've had much better luck with this. Shorter wait, AMERICAN REPS and people who know their ****. When I say cancel I end up talking to some guy in a ****ty call center in a third-world country who does nothing but read from a script. :mad:

I've also had great luck saying "TECH SUPPORT" but they usually end up transferring me to the Android/myTouch Specialist.

Yes, be prepared to go through this 3 or 4 times before you get a good one. The QC from the China plant is pretty bad but you'll eventually get a good one with a good screen.
[myTouch 4G General] btek:
i called again, and told them it was bs...the screen is visibly bad...and I want a new one not refurbed for all my troubles....so they are sending me a new one..
[myTouch 4G General] cthulion:
Good to hear that. Also, don't let them charge you for shipping, when you send your original one back call in to provide a tracking number and insist on being credited for shipping of both units. I got credited for shipping to and from on all my exchanges.

Good news is that it seems most recent orders have been Chinese units with good screens.
[myTouch 4G General] Chedderknight:
Just got my replacement, Made in China(PANEL 2), and just wow, so freaking happy, thanks everyone for bringing this to light, cant wait to break this bad boy in
[myTouch 4G General] hawaiianboi:
After 2 white my touch 4g's both with inferior screens, my first one returned cause I complained of it being slow, my 2nd one having a wobbly trackpad, my 3rd came with the superior screen and a perfect trackpad! Yay!
[myTouch 4G General] sunsean:
Ugh...I've been enjoying my awesome screen for almost 2 weeks now, and I have a dilemma before me...I've noticed a squeak/creak in the bottom front casing of the phone. It gives an audible creak whenever I hit the back button, and sometimes the menu button...even just pressing down on the plastic casing creaks...it's a pretty slight creak, but now that I've noticed it, it drives me nuts.

Now the question is - try to exchange again and risk getting a bad screen thus potentially beginning a long cycle of returns? Or count my blessings and deal with it...?

Hmmm....
[myTouch 4G General] stratax:
anyone know if the G2 has the same problem with the screen and stuff? i dont feel like going through sending my phone back 2 times or more.
[myTouch 4G General] Mexxicanbeauty:
I just noticed that! I have the bad screen and I was willing to deal with it but after I noticed that annoying squeak I decided to call and get it exchanged. Hopefully I get the good screen now! Oh and this will be my third replacement.
[myTouch 4G General] sunsean:
Lol, well I guess our priorities are a little different - the screen I KNEW was totally worth the exchange because it's major. But the slight squeak...just don't know if I'm willing to risk getting a bad screen to mute a little squeak. Anyway, I can really only hear it when I put my ear near the phone. I'm sure I'll stop hearing it all together with enough use. Lol, I just want to enjoy my phone!!
[myTouch 4G General] Amac1222:
Just received my replacement, got the good screen, panel 2, made in china. Haven't done much of anything with it yet. Turned it on, looked in terminal emulator to make sure it was panel 2, then shut it down so I can unroot my bad screen and send that bad screen back. This was my first try so I guess I got lucky. Oh and my FFC is centered now too! :)

To those of you having problems getting them to send you a replacement, I went on and talked to a specialist online and she had no problems helping me out even knew about the issue. Was a painless process and they told me 7 days, I got it in 2.
[myTouch 4G General] cthulion:
Nah, the G2 screen is fine, the problem with the G2 is some come with a wobbly keyboard, some don't.

A lot of people who own the G2 believe the so called "loose hinge" issue to be a non-issue at all.

I had the feeling I would end up breaking mine down the road, so I sent it back.

I do miss it though, it's seriously a phone that don't require custom ROMs, just a root and maybe a OC kernel if you are so inclined.
[myTouch 4G General] ecdy:
The switch was from LCD to SLCD

Ah, I think I get it now; HTC didn't switch from LCD to AMOLED; it switched from ordinary LCD to SLCD. The differences between what we see with the type 2 display and with the type 1 display are the differences seen between SLCD and LCD (better blacks, better viewing angles. HTC switched the Nexus One and Droid Incredible from AMOLED to SLCD last summer because of what they said were supply problems; they might have decided to start the MT4g with LCD but were dissatisfied with the results. Certainly lots of people on XDA-Developers were disappointed with the MT4g's screen, compared to the G2's, when it came out last November (check the archives). Anyway, the likely explanation is probably in there somewhere. SLCD displays are sold by Sony and made in a Sony-Samsung joint venture in Korea.

There are lots of possible inventory and production ramp-up issues might have affected the relative number of S-LCD screens installed in Taiwan and in China, but I would guess once the supply of LCDs dries up we won't see them on any new phones any more.

My new China-built Type 2 (SLCD) phone arrived today; it got to D.C. from Texas in the day since I spoke to TMo customer service's "Android Specialist" on the phone. He was very cooperative, didn't ask about where/when I bought the phone, and didn't hesitate to offer a replacement when I said the screen was washed out. Knew exactly how long I'd been with TMo, though and thanked me for it. Good service like that leads to customer loyalty, as they know.

[myTouch 4G General] stratax:
on the tmobile website it says that the G2 has a s-tft screen while the mytouch 4g just has a tft. so im guessing that out "badscreens" are normal and the "good ones" are s-tft ones that werent even meant for it? lol confused xD

Just got my replacement. Called yesterday and got it today (didnt know they had gotten it next day delievered.) Noticed a bunch of defects on my old phone like crooked FFC, loose buttons, and the trackpad wasnt working right. My replacement today has the good screen, centered FFC, no squeaks or creeks. So happy. For me third one was the winner!
[myTouch 4G General] cthulion:
I never thought of the G2 as too thick to stop me from using it.

About the keyboard, I am not a very careful person, I drop my phones all the time and use more strength than I should all the time, so I thought that I would end up breaking the keyboard hinge maybe a year or two down the line...

I know that if I have any more problems with my MT4G I'll be going back to the G2.
