[Q] Do we still have to worry about panel type?

After 2.5 years with my trusty Vogue, I dropped it yesterday and cracked the LCD screen inside. The phone still works and I can sort of see what's going on on the right side of the screen, so I'm convinced nothing else is broken (including touchscreen capabilities). So, I ordered a new LCD replacement online and will try a little DIY repair when it arrives.
Right now, I have a Froyo build flashed to NAND on this phone. I remember way back in the cupcake/donut days, we used to have to set the panel to type 1, 2, or 3 in default.txt based on the manufacturer of the LCD screen in each particular Vogue. Since this is a replacement screen from an unknown manufacturer, am I going to have to worry about my panel type when it comes to booting Froyo? Is panel type taken care of automatically these days on Vogue?

Yes panel type is automatic for Vogue.

Thanks! After I placed the order for the replacement screen, I started to worry that I was going to have to set the type and that I had just lucked out in the past with the default on my phone. Since I can't see anything, I'm not really in a position to change any settings at this point.
Fingers crossed that my replacement works out. If I can't resurrect this phone, Sprint's offerings aren't particularly impressing me...

the LG optimus is prolly the best i can see at the moment other than the epic and evo, the optimus has the same gpu as the nexus one and an 800mhz processor, only short coming is that it doesnt have notification LED's i thought we moved passed that stuff years ago

Yeah, the Optimus and the Shift are the only two I really have my eye on right now in case my Vogue really dies for good. The Evo and Epic would be nice, but as 6+ month old phones, I'm hoping to limp along until the next generation of phones comes out. With Sprint's announcement about the mandatory premium data fee for 3G phones today, perhaps locking in with the Optimus for another 2 year contract before the pricing kicks in is a good idea...

I played with the shift today the keyboard slid really hard and the volume buttons are on the wrong side

Yuck, I wasn't terribly jazzed about the Shift in the first place, and hearing that just confirms I probably shouldn't go that route. I got my shipping notice about my new screen today, so hopefully I'll have my Vogue back to life by the weekend. I'm terrified that this thing is going to end up being panel type 4, which is to say, something that doesn't exist in the current kernel.

I have the LG Optimus S and it is quite nice!
Very responsive touch screen compared to the vogues screen.
Speed is really good, and there are already 2 replacement roms you can use.
Z4Root does the rooting automatically for you, no need to do a hard hack.
Tweaked kernels exist to allow the device to be overclocked.
Supposedly handles upto 32GB MicroSDHC cards.
Running a 16GB class 6 card in there now, it runs very smooth.
Battery life is quite good.
And - best thing, it was free, just had to renew for 2 years, which I was going to do anyway.

Update! My Vogue lives to see another day. My replacement screen came in the mail and is now working. I can confirm that panel type was not an issue, as Android fired right up and displayed correctly. Thanks to all for your answers and suggestions---my Vogue will not live forever, and I will probably have to pick up a new phone at some point.
Interesting outcomes from the screen replacement:
1) The new screen is much dimmer than my original. I think the backlight is less powerful. Of the three brightness settings on the power control widget, the new screen on high is comparable to the old one on medium. Also, the color gamut seems to be a little different than my old one. It's not problematic or anything, just noticeable after staring at that screen for the past 2.5+ years.
2) The pitch of the vibration has changed--it is a lower frequency now. Also not a problem, but a noticable difference. There was a little box on the circuit board in the lower left corner that was wearing a little rubber hat that fell off during disassembly. I put it back on, but I suspect that reseating the hat must have changed how it vibrates a bit.

Nexus 7 Flicker Issue - Hardware Change Confirmation

I've received much from xda-developers forum, so I wanted to give a little back.
My Nexus 7 8GB had the flicker issue and some screen separation on the left hand side, I contacted Google and did the RMA process, yesterday I received the new one, and the change in hardware has eliminated the flicker issue. I know many people are waiting, hoping it's a software fix (and there may be one), but there is definitely some hardware change that fixed the flickering.
The panel in the new Nexus 7 seems different, as the color temperature is significantly cooler than on my original Nexus 7.
I recorded a quick video, which shows them side by side, it's hard to tell unless you're running full screen and HD, but the flickering is visible. Hopefully this helps those waiting for a software fix not get stuck with a bad screen...
Other than the flickering problem, this tablet rocks!

Could you post your serial# and CSSN off the box?
Doesn't have to be your exact serial#...just a rough one. E.g., mine is 338Kish and it still has the flicker issue...

What makes you so sure there's been a hardware revision?
I have one of the first N7's shipped from Google, and it's flicker free.

I'm not sure there's been a hardware revision at all... It could just be two batches of the panels, one faulty? Or something else. All I know is that one panel is distinctively warm in color (the original) and has the flicker issue, and the other panel is cool and with no flicker. Maybe just a bad batch of panels? Or some of the other accompanying driver hardware? Assembly?
I'm just saying that a hardware change made a major and distinct difference for me.
When I get a chance I'll post the CSSN/SN.

My dads Nexus 7 16gb has quite a yellow tint to the screen and the left side of the screen is sticking up - although I don't think it flickers.. He's getting a replacement tomorrow although it won't be directly from Google. (Tesco's)
I'll post up whether the screen is any different.

This is good info. Once we get more confirmation that perhaps a RMA will solve the issue, then we'll see how good Google is at doing exchanges from the Play store. This entire issue has been so hard to pin down.
It would be nice if Google was more proactive about it and just offered a solution, but that is wishful thinking, I know.
Thanks!
PS my SN on a 16GB model that demonstrates the flicker is:
SSN: C60KBC226---

I just got off the phone. Was on hold for all of 2 minutes. The whole phone call was 8 minutes and 18 seconds. Hopefully it all works out.

heh I did the map test too and saw flicker and planning my return, but I saw some other users were saying tegra devices had this problem. so I turned OFF the wifi, and there was still flickering!
so.. before anyone jumps to conclusions maybe try the map scroll with wifi off

I had wifi on for both of them in the video, brightness set to the lowest setting, and the auto brightness checkbox off. It was happening to me in all applications, the map just seemed the easiest to reproduce in, so it may actually be related to the wifi receiving/sending data.
The new one does not have the issue at all.

can you try them both with wifi off?

I just got around to trying to find this issue on my Nexus 7, and I do see that the Maps app has some "flicker" (i.e., color or brightness changes). If this is what everyone is talking about (sorry, haven't kept up with this particular issue), then let me say that the EXACT same thing happened on my Transformer Prime.
I remain pretty sure that this whole issue is related to the PRISM power-saving tech that's a part of the Tegra 3 platform. I've seen too many wonky issues like this on too many Tegra 3 tablet to think it's not related (that includes the Prime, the Toshiba Excite 10, and the Toshiba Excite 7.7, the latter of which is even an AMOLED screen and so not subject to LCD-type issues).

So I tried to reproduce the flicker on my N7 and was only able to reproduce flicker upon panning in google maps. When I drag the map around and the street names are loading I can sometimes see a minimal flicker (generally when I a lot of loading is occurring). Its pretty subtle and only visible when brightness levels are low.
Don't see any flickering at any brightness level besides that.
To OP, can you see any flickering at all upon panning in your new device? my N7 doesn't flicker like the old one you have, I could probably bare with it.

In a dark room with a Strong wifi full bars and barely and WiFi signal had the same Flickering issue with google maps. It is something else.
So for me it doesn't appear WiFi signal effects it.
Going to be calling Google tomorrow.

The change in colour temp is probably just normal variation. No mobile devices are calibrated (including the iPad3) and they all show a fairly wide variety in their white balance. It is possible, though, that the flicker has some sort of causal relationship with the screen lift.

My search led me here after noticing the flicker issue while browsing the web on my n7 at night.
I just did the map test and it flickers every 5 secs with the WiFi ON. With WiFi OFF there is no flicker. Same with all the apps that use WiFi.
So is a this a HW or SW issue?

There's already a large thread on screen flicker. Not sure why we needed another. Maybe a mod can merge them.

Thanks for the post. I received mine on Tuesday and noticed the screen flicker with the auto brightness. Called last night and they're sending me another. If the RMA flickers, I'll wait until Google's new Motorola division begins creating actual PURE Google products.
Here's my Nexus serial: xx0KBC019770

My first device had the screen separation issue. I have since had this replaced and the new one has the screen flicker.
It is most noticable when the brightness is at its lowest, above 20% it _almost_ disappears. turning wifi off seems to stop the flicker.
In the video did you have the brightness the same on both?

Post 4 months (of the N7 release)

Wanted to get a feedback on the N7 run post its initial 4 months... I know all the issues reported were a small percentage from the actual, but are the old known issues resolved now? Are the latest units released from play store the next generation builds?
How's it going for you guys with the device?
I see GOOG doing a N7 with their N4 release (wow! ). Also see the ipad mini rumors coming true (wow, what a rip off). Really interested to see how's it going with this tablet?

I just bought a N7, and am loving every minute of it. The initial reviews scared me with so much going wrong such as the screen lift, GPS failure and other such reported bugs. I really haven't owned my tablet long (about a week or so) but I haven't experienced any of the complaints that were mentioned with the release. Everything works great on the device I got from office max. The main thing that all the complaints got me was a 2 year retail warranty, specifically because the manufacturer's has certain specifications for the glitches (is X number of dead pixels) for a replacement.
The 4.2 update is really all valid and mostly has to do with preference IMO. Hope this helped, because I definitely know the feeling after rummaging through this foum before buying.

I bought the original Nexus 7. I had a 16gb C80 variant. It was fine at first, but after a couple of weeks of light use (I was too scare to use it without a case), I got left hand screen lift. I took it back and got a refund. I was deciding what to do and then heard the rumours of the 32gb Nexus and thought about getting that. Then saw the 3g rumours and decided to get that.
I have heard that the latest "normal" Nexus's have improved in their build quality and that the problems of the early days are less and less. That said, I have not heard from anyone yet saying that the left side design flaw which is causing the lifted screen has been resolved. I "beleive" that they are still shipping units without the two screws on that side. It may be that is no longer the case, but I've not heard from anyone on here that it isnt. However, it seems screen lift etc is markedly reduced.
The 3g version has a re-designed rear. The microphones have been moved and there is now a sim card slot on the left side. I'm not sure if they have taken the time to address the screen lift design flaw, but my 3g has no problems currently with screen lift, bleeding, dead pixels, speaker etc. However, I've only had it a few days. I'm not about to open it up to see if its been fixed The 3g I have is a B0 serial number, so is a new model.
I was very uncertain about getting another Nexus and considered almost all the alternatives, but I'm glad I got it in the end. Currently its working great. Battery life is not the awesome figure I'm reading here of "2 days with normal use". I'm using it normally and I get a day out of it...mostly due to screen drain.

I have had mine for two months and so far I love it. My cousin bought one shortly after based on mine.

I've got an original 16gb pre-order N7. It arrived flawless and to this day has stayed that way. I use it a couple hours a day, no case and i have no complaints. Zero screen lift, no light bleed, no gps issues, speaker output is loud and clear. I Couldn't be happier.

Ya my 16gb N7 working fine since day 1. Never had any of the problems. Right now it's just the long wait for a custom ROM running 4.2 that sucks.

Have mine about 10 days (32GB) and it'll be replacing my laptop after i get an external HD to copy my music onto then laptop sold and just use the Nexus.:good:

32Gb WiFi only from Radio Shack. Some minor light bleed at top, 3 points - suspect screws are too tight. Flicker even without auto brightness on at low backlight levels persists on 4.2 even with strong WiFi signal - even with other custom kernels. Fix for all? Though hitting the battery - I just turn the brightness up a notch or two.
16Gb WiFi - flawless. No light bleed. Flicker very nominal, even yellow screen tint is very faint.
Newer Versions - not all issues are fixed yet. Go for replacement on the 32Gb? Haven't made up my mind yet. I suspect I will suffer the same issues with a replacement and not sure it's worth my time.

I'd picked up the 16gb one initially but that had a horrendous and completely washed out screen so took a refund and ordered a new one from another place and this one has been perfect. I love it and it's completely replaced my phone.

Death grip - signal loss

Hello.
I just watched 2 videos on youtube, both showing signal loss when the palm of your hand touches the lower left corner of the phone.
Can anyone confirm if this is true??

No signal loss on my phone.

what do you think this is, iphone?

Just tried, no signal loss.

Just tried it - holding it in that corner as well as covering both the top and bottom parts of the back (which are the antennas). No signal changes.

You're holding it wrong!

There is slight signal loss on my One (Sprint) when my palm covers the bottom left corner of the phone, but I wouldn't call it a "death grip." For me, it's the difference between 5 bars vs. 1-2 bars.

Anyway, anyone who holds their phone in a "death grip" during normal use is a bit off. Here, I need to make a phone call; let me hold the phone just as tight as humanly possible. Please...

Try holding with your left hand for 5 seconds.
That's what I noticed. From 5 bar to 1

Might send mine back. My signal rose from 3 to 4 bars when i just covered the bottom of my phone. Also, i l placed it on a table and looked at it for 5 minutes and it fluctuated from 3 to 4 to 5 and back without me touching it. I am so disappointed with HTC right now...
In other words, no death grip here. If you have a problem with your phone, send it back. It does not seem to be a widespread issue.

mine singapore's singtel set, no problem

I can confirm this happens on the T-Mobile version too, but it doesn't actually appear to have any effect on phone calls, at least in my experience. I haven't dropped any calls, nor have I noticed a change in sound quality. On a somewhat related note, I can also interfere with Bluetooth audio streams simply by putting my entire hand over the top right corner near the FFC, though it obviously looks wrong and feels awkward to do so.
It's a known fact that many phones have signal attenuation when you put your hands on them in certain places. If it's that big of a deal, you can always invest in a good Bluetooth headset to keep your hands off it.

Oh great just what we need more OCD driven videos.

Tried it with mine - was -83dBm on the table and fluctuated between -83dBm and -79dBm in my hand.

Just tried it, mine is completely fine. . .

This will happen on most, if not all phones. If you cover an area it needs to be usually exposed to maintain signal, what do you expect?
When it happened with iPhones however it was funny to see everyone who hates iPhone's making a big deal out of it...

[Q] Still worth to buy?

I am going to buy a new android cellphone tomorrow and after too much research Xperia Z1 is the phone that fits my budget to its worth with specifications. So my question is after approx 1 year is it Still a value for money? Are there any issues i should be worried about?
My alternate to this is LG G2. Thanks in advance.

Get the G2!
You will get a bigger screen, thinner bezels, Better battery life, double tap to wake and it's smaller than the z1
And the z1 has an annoying problem with the touch screen where it stops registering touches for a little while (unimaginably annoying when it happens during scrolling) and the screen looks yellow,that makes my head hurt

G2 have those touchscreen problems too (as I heard)
Maybe you should check on the LG G2's Q/A section and see the problems there (if they have one).

I would find it hard to recommend this phone to anyone.
Just to add to the issues seen by some
I have touch screen issues, in fact the whole screen is crap. The colour and brightness aren't anywhere as good as my wife's Galaxy Note 2 (yes, Note 2, not a typo. A phone more than a year older than my Z1 has a better screen). The touch screen doesn't work properly at all, you just get used it it. It's not accurate and slow to track movement of your finders. Add to that the fact that it seems to completely ignore your touches when you've been using the phone for a bit (possibly temp issues?) and it makes playing games impossible... and like @masterofnocrack said, when your dragging or trying to flick through a long list, it randomly selects something from the list and you've no idea what you just tapped on, it gets more than infuriating.
Locking up - my phone will decide at frequent times to lock up. It will not turn on from sleeping (screen off, standby, whatever it's called). I had resorted to holding VolUp+Power to force it to reboot but then found out that if I just wait it will come back on it's own. It's like some app is using 100% of the CPU and lock's the OS up. I seemed to get the problem most of the time when running apps like Endomondo where it keeps tracking GPS etc while in standby but since uninstalling Endo, its still the same. Not really a Z1 issue but more Firmware, but still a nail in the already tightly nailed down coffin. Also screws with Tasker (see below)...
I did have issues with the OS killing background apps like Tasker (which is really annoying because if Tasker gets killed, all my profiles and settings got messed up so I could be out of the house with no mobile data enabled or in the car with no bluetooth), but I rolled back a ROM version to fix that. (I'm on stock ROM/Kernel but rooted.)
I would sell my own children for a new phone, which is probably a good reason I don't have any kids.
Look somewhere else. If the G2 drops out of the running too, keep looking. DO NOT get a Z1.
I know some will disagree and perhaps think I'm being a bit harsh; and if you've got a Z1 and it works perfectly, good for you and congrats. But knowing what I know now, I wouldn't take the chance of getting a Z1 that has issues.

I have no clue what you are talking about. My wife and I both have a Z1. Hers is running on stock and mine on custom. We never had any of the issues mentioned above. So from my point of view it still is worth the money.

Some have problems and others don't, but it's it worth the gamble?
The OP should save up and get something better like the Z2 or Z3

The answer is.. Yes!
The Z1 is still hell of a beast, performance- and battery wise, around 1 year after release. It's bang for the bucks phone nowadays. Get it, and fine tune it to suit your likings. Nuff' said.
I am willing to help you out with the fine tuning, if you get this lovely ****er into your collection..

I didn't mean to piss on any one's camp fire and I'm glad for @memphis77 that his and his wife's phones both work perfectly, but I know from these forums that there have been plenty of users that have had issues, and even those that have pursued the issues with Sony have just been sent a refurbished phone that had the same issues.
It's just my opinion and personal experience that makes me say do not get a Z1.

It's so beautifull and powerfull. If you love this phone, so buy it. You won't regret it. And of course, it's still worth to buy

I'd say it depends on what you pay for it. I bought mine about a month or two ago for a little over 250 and I couldn't be more pleased.

One more thing to add, and once more, YMMV; piss-poor data rates. WiFi signal is weak at best. The WiFi signal goes down to 1 or zero bars in some rooms in my house but doesn't actually disconnect from the WiFi so the transfer speed is so slow I turn WiFi off and use either H+ or the odd 4G signal I get. You might be thinking "well you're obviously too far away from the router you pillock." Well, maybe an upstairs room is too far... maybe it's not. My wife's Note 2 can still use the WiFi all over the house, my Tab 4 can use the WiFi, my Raspberry Pi with a cheap ass god damn WiFi dongle off eBay can use the WiFi, but not this piece of crap phone.
In a decent H+ signal area, an iPhone 4 beats this with download speeds using mobile data. I have gotten 20Mb/s on 4G (1 bar in my house which was impressive but a fluke as I've never seen that speed again). Looking at speedtest results isn't exactly the be and end all of deciding which phone to get, but it's just another area this phone fails.
