I just received my new Galaxy Note international version. I bought it from Amazon, and it was listed as 1 year US Warranty, now they changed the title to International Warranty. The seller is "WorldWide Distributors", and they said it has a 1 year international warranty, but has no US warranty.
Anyways, when I opened up the box, there was only one sticker on the bottom of side of the box, so I didn't have to tear off any stickers to open it. Inside, the phone had some fingerprints, and I noticed that maybe the seller just checked it out before sending it to me.
After searching for rooting, I learned that there is a "custom binary download" counter so I stopped and just decided to use stock rom for now without root. Then I found out when I did "vol- home power" to go into odin mode, it shows "Custom binary download: yes (1 counts)", with "samsung official". Does this mean the phone was flashed by somebody and it is a used phone?
The seller charges 15-20% restocking fee if I want to return it, and the warranty part is really fishy. I already ordered the $1.50 usb thingy that resets the counter, so I'm not really that concerned, but it's just that I feel bad for paying $660 for a supposedly a brand new phone when in fact it might be a used one.
Some more information:
Android version: 2.3.6
Baseband: N7000XXLA4
Kernel version: 2.6.35.7-N7000XXLA4-CL886827 [email protected]#2
Build number: GINGERBREAD.XXLA4
Now, my 5 hours usage review--
I feel the phone is slow. Maybe I feel this way because I had a Nexus S with custom ICS ROM (1.2GHz OC, single core). It feels like I came back to Windows XP from Windows 7. Everything is kind of sluggish, and I have ADW launcher with minimal effects. There are no updates for the ROM when I checked, so I think it's most up to date. The screen is kind of ugly too because the damn pentile shiity thing. One thing I didn't like about the Nexus S was the pentile screen, and now Galaxy Note is kind of the same way when I make the letters appear small. Of course, this can be overcomed by using larger fonts since Note has a larger screen. On the back where the battery is, manufacture date is Feb 2012. Any suggestions would be greatly appreciated.
Quadrant scores 3598. Reviewing pictures in QuickPic is very sluggish (maybe from the high res screen?).
I hope ICS will solve the performance issues.
Okay. You've got a used Note. If you purchased via Amazon, you won't have to pay a restocking fee. The bottom line is that you paid for one thing and received something else. Amazon has you covered. The seller can't do anything about that.
Second, if you'd quit reading text on your Note with a magnifying glass, it would look fine. If you're not using a magnifying glass, then the only reason you know it's a Pentile® display is because you read it somewhere. All text looks like crap when it's so small that each letter is rendered by a whopping two pixels. An RGB stripe won't look any better.
Bend the seller over. Get yourself a new Note... and just enjoy it!

Thanks for your reply! So, +1 on the count means it is a definitely a used?
The Pentile is noticeable, and I learned this word after searching for why the text is not so clear when I had Nexus S. It's not because I read it from somewhere.
The black text on white background is not as sharp as I want it to be. The small text on webpages or even thin black lines are not made of clear lines. That's how I know it's Pentile display. Actually, it was confirmed after searching about it.
Compare this with any other regular LCD display, or iphone4 or ipod touch 4th gen, and you'll know what I mean. The large screen kind of compensates the lack of sharpness for small letters because I can make the fonts larger, but I was hoping to see it sharp even for the small fonts. I have a good eye sight, so that may be another reason.
I don't make much phone calls, so I like the form factor and all. I also have a wacom tablet, so I know the limits of the pen. But not having a stylus calibration is kind of odd.
Anyways, I guess I should send the seller an email about this since they open M-F, and it's already Friday evening here.
I have an iPhone 4 and an iPhone 4S. The lack of sharpness is due to the Note having lower pixel density than the Retina display. I know you looked it up when you had the Nexus S. And I know small text isn't as sharp as you'd like it to be. The point is that it's as sharp as it SHOULD be. If the Note had an RGB stripe display, text would still be subject to clarity loss as it's reduced in size. The reason you're noticing clarity loss has nothing to do with the Note's display matrix. It's because you allowed your eyes to adjust to the 320dpi display on the iPhone 4/4S. Trust me... your eyes will adjust to the Note. Mine did. That being said, the Nexus S doesn't have the pixel density that the Note does, and you CAN see the Pentile® matrix on it.
As far as your used device concerns go; yes, you were sold a used device. Moreover, you've been sold a used device with a voided warranty. Not only did someone use your phone, at some point, they flashed it with a custom kernel or OS. File a complaint and get a new device or a refund.

+1 count means it was flashed once with custom ROM. And naturally samsung / retailer won't do this.
So sure it has been done by some user.

I bought a new Xperia V for my son and when I looked more carefully i noticed there are differences between them. The screen is different, one of them has two more sensors and the front camera is different as well. Both of them are made in China. Check this:

as i've checked, i'm pretty sure that both phone are original, not fake, i dont know why they are different, but i'ma show you some ways to test these phone (just to make sure).
1. turn on the bravia engine 2 in setting/display, open a sam picture using Album on both phone and see which is more beatiful (set full brightness)
you can change the view angle to see which phone displays better.
2. download the antutu benchmark on playstore (version 4), run it on the phone and see which phone will score higher, (they can only fake the phone, but they cant fake the real power of qualcomm snapdragon s4)
3. type *#*#7378423#*#* and have a check.
good luck man

There is a topic for two versions of xperia v displays. My phone is like the phone in the left but without the red dot in the front camera. I think the phone from the right has better colors. Can you make some pics with display on with different wallapers?

If that was so, then this would be the first product I know of produced for Chinese market and international market, where the Chinese variant had better properties. Drive a German make car in China and drive one in Germany, you will know in seconds what I mean.
One of them will have a better display. In service menu you check touch firmware version one of them will say b which is the best display on the phone and the other will say a or c

Yea these are white from the factory. But colours may be user modded, that does not say anything.
The pics are lousy but from what I see, these two show subtle differences in housing design. They are not coming from the same factory. The screen quality seems is completely different. Anyway, don't buy from China if you don't like certain issues.
V has 3 different display vendors: Sony, Sharp and Toshiba. With at least Sharp there's no visible second sensor window in the glass.
Checking which display it is can be done if you have root access; check dmesg output after a reboot for strings containing “panel”.
Had a friend record a video and I produced it, just in case anyone is on the fence about upgrading or is trying to decide if the price jump is worth it!

Had the note 3 and sold it due to its proximity sensor not working. Wish I hadn't. Have the note 4 now and love it. To be honest the only real difference to me is the new build quality. Less plastic and more metal.
The note 3 seemed just as fast and great. I would have bought another note 3 but they were selling only 100 euros less than the note 4
Some it was better in note 3...note 4 is needed updates asap
I have all the Samsung Note.
The difference for me between a Note 3 and 4 is all speed and screen.
I'm so happy with the upgrade and I must say I didn't expect to be so impressed about the difference.
So satisfied, but battery is hopelessly bad .
Like Note 1 and 2 the battery drain is ridiculous.

No the sensor was not installed properly and since the device was rooted the knox was tripped. So warranty no go!
I always rushed in upgrading Samusng phones like I bought note 2 and note 3 brand new after few days of launch but not any more. I believe the price difference is not worth spending as of now so I am waiting for price to go down.
I got my upgrade yesterday from note 3 to note 4 and apart from the build quality and the camera there doesnt seem to be that much of a difference if im honest.
i use it for work and was a little disappointed that knox was not available on the 910f model yet, i also tried my knox but that doesn't work on this model at the moment either.
apart from that it's all good ☺
It's not a 'shut up and take my money'
It's like a 'go back to the labs'
note edge looks more attractive. if it has borders on 4 edges I would say 'shut up and take my money'
I'll hold my N3 for a while. the gap prices are short in my country.

I'm sure Samsung know that metal is less than ideal on a phone, it's a stupid fad.
Note 4 has sharp edges too. It also has that bevelled edge to the glass which is great if you run without a protector but terrible if you do I hated the 2 for that.
Definitely not moving from the 3 to a sharp edged phone, my 4 upgrade in January will most likely get sold immediately.

My experience with the Note 4 is almost the opposite, apart from the screen. Battery life on my Note 4 is very good, at the end of the evening always between 30 and 40% left.
Speed of the device is a different story, stutters all over the place. Totally random, while switching launcher pages, scrolling through calendar or contacts (appr. 120 contacts) and other apps with "list view". My Note is 100% stock.
Not to forget, the fingerprintscanner is an annoying piece of hardware. Having my right thumb fingerprint registered 3 times I always have to swipe more than once/twice in order to unlock.
I'm absolutely not happy with the "update"!!

Well I would have done that, I live in Germany but it would have taken them quite a bit of time. I sold it for 500 euros and explained the issue to the buyer. I bought a nexus 5 and Nexus 7 2013 with that money. To my surprise the Nexus series do NOT accept USB OTG natively. I had to get Stickmount from Chainfire to use any additional storage. It really made me wish for my note 3 back even with the sensor issue.
When my wife got the s5, I immediately realized why I like Touchwhiz and its lag. It comes out of the box with a lot of features that other devices need root for..
Like USB OTG
Customized quick settings
All share, (no need for all cast)
Also its cameras are always better with its features.
Plus micro sd
Battery removal and last but not least, It comes with in my opinion the best screens. I love Super OMLED.

It sounds like you don't have the latest firmware.
I can't make my phone lag at all.
I can scroll as fast as I in contacts (988) pictures (764)
with out any lagging.
If you take a picture and press the photo on the left lower corner.
If it doesn't pop up instantly I guess your phone is on the same firmware as min was before I updated.
It was lagging in every way before update.

You're right, I don't have the latest firmware.
i got note4 cheap so upgrade was right to do.
in my opinion they polished everything that was not so good on note3 like edge, camera, adding fingerprint lock, front camera, fast charge and for me usb 2.0.
but if someone would ask me would you pay 50% more to get note 4 i would say no.
Biggest disadvantage on note 4 is that he does not have temperature and humidity sensor (((
Just picked up my GS6 Active. I held out due to the smaller battery in the GS6. Coming from a GS2 rooted running pure CM, this thing is filled with bloat. Anyone else get one?
Anyway to root this thing to install TiBkup and freeze the bloat?
Considering it just came out today, I'm going to go out on a limb and say no.

Jackal2001-
I'm in the same boat; since the GS2 (which I'm still using), this is the first Galaxy S* that's made me want to upgrade. I'm going to (try to) hold off for a week or so though, and see what people's experiences are.
AoN.
I actually skipped the Active this year on purpose. I Just ended up getting a 64GB S6 and putting it in a case. I came from an AT&T S4 Active (SGH-i537) and was disappointed by how restricted it was and how difficult it was to find support in the development community. I waited to get an S6 until a couple weeks ago, until I was sure it was rootable and flashfire was working.
I also didn't want to give up the fingerprint sensor which was a feature that was very attractive to me on the S6. I am now quite happy. I might not be able to shower with the phone now, but the tradeoffs were too big to get me to consider the Active this time around again.

I'm with you. I much prefer the regular S6 to the Active. I've got a regular S6, gold, 64 GB AT&T model and I love it.
Got one today as well. I believe the kernel is too new to use PingPong Root.
I am actually not that worried about it. I just disabled the apps and done. I'm actually tired of romn' phones and doing all that jazz anymore. If they come out with a one step root I may do that.
I'm more concerned with battery life and don't care about fingerprint scanner. Waterproofing is just a bonus.

It is an awesome phone! I wanted the built in weather proofing, and the larger battery is great so I waited patiently! I did not care that the battery could not be easily swapped out, but I did want to be able to replace it myself when it needed it as well as do other minor repairs. At the very least I did not want to mail the phone off but take it in to a nearby repair center. I cannot find unboxing videos or detailed pictures. Can anyone post some especially of the port on the bottom and back? I was set to get this, but it is my understanding that it is going to require a heat gun to take the back off too just to replace the battery or even replace the charging port door--something I can easily do with the regular s5 model? If I had a Samsung repair center near me like an Apple center, I may have still considered this phone. There is still a small part of me that is still hoping against the odds that this thing is not glued together, but I am told it is. Why could they have not just tucked the sides under the metal flaps to hold the back down better and just screwed it down. They have screws there anyway for looks????
I am still trying to decide on getting this or getting something else like maybe the s5.
I am not sure about being limited to the 32 GB storage either, but I think I could get by with an OTG adapter for special events when I needed to record them. Wish there would have been a 64 GB option.
I also do not like the lack of MHL support as our Internet here is slow and not good for Chromecast.
For anything else I for go for pink, frilly looks (I am a middle-aged mom), but I just wanted a phone that I could use without worrying about day-to-day use. So this phone in an Otterbox (the black or gray it is going to come in) is just fine with me!
Thanks for any information for those who went out and got this. I have the feeling I am going to going with another phone though

I spent an hour playing with one in the "flagship store" in Boston. I finally decided that I wanted to buy it and the sales guy says oh we only have it in Camo white.. I wanted regular grey. They had 4 display models on the floor. I guess I'll have to order it online..
So I just did an overnight battery test. I have GPS disabled and WiFi set to turn off (more data useage) when it goes to sleep. I have NFC disabled as well as the LED on the front, etc. Overnight for 10 hours the battery dropped 6%. For me that is pretty damn good for a bloated factory image.
So how's the cell signal strength so far? Curious since it's got a different type case as opposed to metal and glass.. Also how's screen look. Solid white background have pink tint?

I see no pink hue, looks solid white to me on a google screen.
If I let this page sit on high brightness, http://jasonfarrell.com/misc/deadpixeltest.php?p=2, I can see either a slight pink tint toward the bottom of the screen or it is me going blind from staring at it.
I don't travel a lot so cell strength seems normal to me.

Have you checked to see where it was assemble (Vietnam, Korea, etc...) and what type of camera sensor it has? Isocell vs Sony? Sorry for the 20 questions just wondering how it compare to regular S6.

See if this works. Copied from techtrikz and written by Kannan.
How to identify the camera model on your Galaxy S6/S6 Edge
1. Open phone dialer and enter the below code
*#34971539#
2. This will open the ‘Camera Firmware Standard’
3. Tap on ‘ISP VER CHECK’. This will show up the rear and front camera make.
4. For Sony sensor, it will be ‘SONY_IMX240_FIMC_IS’ and for Samsung Isocell sensor, it will be ‘SLSI_S5K2P2_FIMC_IS’.
I just recieved my new Samsung Note 8 an hour ago. Having previously been using the Note 5, I was very much looking forward to seeing what it could do.
The first thing I wanted to do, of course, was charge it. I placed it on my Samsung Fast Wireless Charger, and it flashed up 'Advanced Charging'. So I switched to the included fast charging plug, and again, it showed 'Advanced Charging'.
Checking the charging settings, they both showed 'Advanced Charging' for wired and wireless, where my Note 5 shows 'Fast Charging' options.
Is there a reason for the difference? So far, everything else seems ok, but the difference in language seems to be something I should know about.
I have an unlocked Note 8, model number SM-950U.
Any thoughts on this would be really appreciated.
Just want to bump this post up instead of creating a new one. Because my Note 8 says the same thing as well.
