Easier way to remove the battery cover?

Removing the battery cover on the Nexus is rather irritating, is there a specific way YOU remove it, I know its simply sliding it up - but I'm still having troubles.

Heh. Knew I wouldn't be the only one having problems with it.
I posted a thread about this some time ago. This was the method that worked for me:

Try this, hold your phone in your left hand facing down with your index finger and thumb just on the sides of the phone just above the capacitive buttons. Then place the ball of your right palm on the back of the cover and push up while applying a little force, it should open pretty easily.

I find it easiest to hold it so the top of the phone is facing away from you, face down. hold it so your fingers are on the screen side, kind of going down the length of the screen on each side and place your thumbs about 1/2" in from the edge, just above the split.. on the half that slides off.
Now... counter intuitively... press your thumbs down into the phone with a little bit of forward motion too (the direction it slides). If you have your thumbs in the right places, you'll easily defeat the hooks that hold the case together and it'll pop right open.
@grainysand the palm method also works pretty well too, but I still tend to need at least 2-3 tries removing it that way. it's rare that I can't get the shell apart my first try using the thumb tactic.
good luck! it must have been pretty hilarious watching me get the thing apart the first couple times i tried.

??? Hmmmm... ....Hold it in your left hand with screen facing down...put left thumb on bottom of cover...right thumb just below the camera lense cover...Right index finger on top of the phone...making sure you're not holding the cover down with it...and push up with both thumbs.

[Q] S Pen Calibration

My S Pen doesn't seem very accurate. When I touch the screen with it, it is off by a couple of millimeters. This is very annoying when drawing.
Is there a way to calibrate the screen/pen or something?

Well, that "problem" it isn't that. They need to do that because they want you to see the line that are you drawing.
If you enter in to the options of the drawing pen and change to left handed, you will see how that millimeters move to the other side of the pen. So, 1 2 up and 1 or 2mm left/right are necessary and it is how the wacom screens works. In other side I have tried a lot of wacom devices and this is one of the most accurate.
The only problem that I see it is the pen that if you don't give enough pressure it doesn't works, and if you give much, then it will writes in "bold" rather than skinny lines.
Try to move the pen without pressing it, only light slide and see how it doesn't do anything.
Other funny thing on the wacom devices is that the accuracy is not the same in the center of the screen and in the side of it. Problems of magnetism

Did you try pen pressure with autodesk sketchbook, is it working ?

Hi
Just a quick question for you who have the phone and use the pen. When you use your pen for drawing, what happens when your hand (which you hold the pen with) touches the screen? It must be annoying always to write without touching the screen with the hand/fingers like you would do if you were to write with an ordinary pen on a classic paper.

The good thing is that u can touch the screen with finger when u write, unlike pure capacitive screen
If u touch the note with finger u will get a mark, ie u can use ur finger to write on the note
If u touch the area of screen above the note, the note app disappears to show the app beneath it and when u remove the finger the note comes back. This is to jot down things from the app beneath it. Hope this makes sense.

I'm curious, are you left handed?
There is a setting: settings -> pen settings -> dominant hand.
I changed mine to left handed (which I am), and when my right handed friend used it, he complained that it was off by a millimeter or too to the right.

Thats not an issue as when the pen is touching (so it's active), the screen will no longer accept any additional touches. So with your fingers, multi touch will be active for upto 10 (I believe) seperate touches at once, but as soon as the pen is touching the screen, it will only pick up the pen and no additional touches from your fingers etc so you can rest your fingers on the screen while you are writing.

Thanks for the explanation that makes sense nevertheless the offset is annoying and difficult to get used to.

Try this. It works for me.

try turn on the auto rotation
Or turn off auto rotation
Just try...

Actually all this is nonsense.
The offset is variable and depends on the angle of the pen.
The most simple way to test this and to get used to it, is to open
a S-memo. Then instead of using the line option you choose the
eraser option. Touch the screen and on the screen you see a circle.
Now with the pen on the screen change the angle of the pen and you will see
the tip of the pen 'move' inside the circle. Now get used to the angle of the pen
where the tip is in the center of the circle. Once you are used to this angle your pen will be dead on when drawing.
Remember way back when you learned how to write, it took you days to get used to holding a pen or pencil the right way.
I can recommend the official samsung s-pen holder for a much nicer feeling when using the pen.
Hope this helps

I just want to clarify thhis, the pen needs to be touching and in writing pressure on the screen for it to stop accepting input from your skin.

Go to photo editor choose a bright picture choose the pen option from photo editor hold the phone on portrait mode and try to draw on the edge with a smaller tip on the pen then go switch dominated hand on spen and try again and then come back and say this isn't a devs calibration problem or coding or call it how you want. But give attention to

This idea that we need to see where we are writing is just as imbecilic as Motorola's idea of protecting users from rain drops. Back then, it stoped you from playing any games that required you to keep your finger stationary for more than 15 seconds. Here, it makes drawing and writing very difficult.
I don't ****ing see where I'm writing when I'm using a paper, why would I need that on my phone's screen?

I have also problems using my spen. Is it realy normal to put quite much pressure on the pen to write sth.? It's realy hart to dram thin lines without any interruption of the line..... feels as if that'S not "normal"
how about yours? Is that normal?

I don't know if this will help, but my s-pen was off a few millimeters too after an official update. I tried calibrating the accelerometer and gyro and the s-pen became accurate again. I'm not sure though if this indeed did the trick or if my mind was just playing tricks on me.

Thanks, I'll try that, too. But my Problem primarily is not the millimetres off, it's the pressure needed to draw sth.
I also wrote Samsung's support yesterday. I'll see what they say.
I won't flash my phone before I can be sure that it's okay and I don't have to return it.....

iam having the exact same problem..please tell me if you find a solution.
it didnt happen with the pen which came with phone..it had the millimeters away problem..and when i lost i ordered new pen this new pen has more pressure problem..its very hard to draw thin lines

This is absolutely correct... the stylus orientation definitely does affect the point offset.
The problem is (at least on mine) is that the "left-handed" setting appears to do nothing. The point offset is the same regardless of the setting (it's biased for right handed), so trying to write left handed is very hard.
How many people that are having the problem are 'lefties'? If I pretend to be right handed, the offset is perfect (regardless of the left or right setting). This has to be a bug and I'll presume it'll get fixed soon. Because it's really quite intolerable as a leftie.

Today I upgraded my phone to Criskos rom with Abyss kernel and all accuracy problems are gone for me.Never had problem with pressure.

[Dissapointed] Fingerprint Sensor

I'm new to the S5 literally got this phone 2 days ago. So far I'm loving it everything is good..until I get to the fingerprint sensor. Anybody else Dissapointed on how unacurate this thing is? I like the idea of having it, but they need to fix it or update It somehow. 9/10 times I have to put my password in instead.

I get mine to work with one hand 98% of the time and I can use 4 fingers rather than 3

I wish I could be disappointed. My work disables fingerprint security to access their network. I have to use pin or password.

The quality of the fingerprint makes a huge difference. My wife works in a pretty caustic environment and her fingers get kinda mucked up, nothing we can do will make it work for her. However, it works flawlessly for me.
Another issues is the limited size of the actual scanner makes it dificult to read the fingerprint acurately

+1. No issues here. I was pleasantly surprised.
Though my laptop and my work's timeclock have fingerprint scanners that work in much the same way -- so I've had plenty of practice. :good:

For the life of me can't get the finger print scanner to work well at all. I tried three different times setting it up with very low success rate lol.
Finally just do a swipe pattern out of shear frustration. I would love to do it one handed with my left thumb and tried to set it up this way to no avail.
I have better success if I hold it with left hand and swipe with pointer on right hand. Swipe pattern is so much easier with a 100% success rate.

Works for me every time, youhave 3 finger prints you can asign, use the thumb you unlock for all three doing them in different angles, even switch the angle up on every swipe when setting one print up, figure out the motion you would normally use to unlock it and try setting it up that way.I actually set my right thumb up for 2 of the the 3rd I used my left thumb just in case I'm holding the phone in my left hand, but you don't need to swipe your thumb vertically down, as long as your swiping the whole button it should be good, start with your thumb horizontal and move it a little counter clockwise each time till set up is done.works lawless for me unless I'm at work and my finger is dirty, witch is good because it knows, it's very accurate if set up properly., hope that helps

I've tried numerous times to set it up but it rarely works for me. I had to enter password so many times I disabled it all together. I'll admit that my fingers are frequently roughened or cut at work but even using fingers on my left (non-dominant) hand which are relatively unscathed only gets me success once in awhile.
Maybe it is just not usable for those who work with their hands, bummer as it seemed promising. I rarely had any lock on other devices and thought this might be a lock I could use.

Try again it works , good too, 9 outa 10 times for me,I'm a union electrical so my fingers are always getting cuts and scratches, blisters from spinning wire nuts. Try setting it up like I suggested use your thumb horizontal to the phone or like 45 degree angle like you would if you were doing it one handed, then turn on your power key to lock your phone instantly so you can test it without waiting for screen to time out to lock.

Trying again. Results are better - if I swipe slowly it gets most attempts but not every time. I'll try it for a day and see if I improve, maybe it is more sensitive to angle and velocity than I am. That may improve as I repeat the movement enough to get used to it. However security isn't a large concern so I'm not too upset; it's primarily just the usual annoyance when something doesn't work for me.
Maybe I am just I am expecting too much, do you have to swipe pretty slowly?

Register up to 24 fingerprints with this simple trick

Guys, i just discovered something amazing!
You know when you're adding a new fingerprint to the list and you have to swipe the scanner 8 times? Well, nobody said it had to be that same finger, all eight times.
I was able to register all my fingers because with this method i have 24 (3 x 8) places to store fingerprints.
I've seen posts where a dude asked if there was a mod to register more than 3 prints, well it was just that easy!
Can't say if it affects the accuracy of recognition as i found this only 5 minutes ago but so far it seems fine with all fingers.

I registered the dominant thumb twice (2x8, yielding 16 prints of one finger), which resulted in much improved recognition.
I suspect that even though you were able to register more fingers, the real life performance of the finger print scanner will be potentially impacted in a negative way since the database of each finger is scarce. In an less than ideal environment such as when you are walking, you might experience poor recognition in the long run requiring more swipes.

I too registered my primary thumb 16 times.
The first time i set it up, i registered my thumb 8 times vertical and 8 times horizontal. I have large hands so i'm able to unlock and swipe with one hand, but i thought it would register the horizontal one as another print.
After a week i removed the horizontal one by accident. I could still unlock it horizontally or in any other direction for that matter, but the acuracy did indeed suffer from that.
I would suggest registering 2 sets (2x8) of your primary unlock finger and the last one a bunch of random fingers or even a finger of your SO.

Never even thought about sideways swiping until now. Plus it is pretty accurate using multiple fingers within the 8 scans. Thanks!

I did the same thing, works great :laugh:

I registered my dominant thumb (one handed) for 8 times vertical swipe and 8 times for horizon swipe. Registered thumb from second hand for 8 times vertical swipe. In one handed use, it works better by moving menu button to top with vertical swipe. These directions (horizontal and vertical swipes) are reversible. It is more comfortable to swipe menu button at top then at bottom.

Using almost all fingers to unlock.

I just found out that we can assign more fingers to unlock our S5 using finger scanner.
When we are registering the fingers. We are asked to swipe the fingers 8 times.
Here's the trick..Instead of swiping the same finger 8 times, swipe different fingers one by one..and all the finger prints will be registered.
If this was already posted earlier...then my bad
Sent from my SM-G900FD

I don't think that is a viable option. It seems the wizard scans the finger 8 different times so it has a better reading of the print in the event you don't get an exact perfect swipe. The fingerprint unlock is already awful enough and doesn't work too well. Sure, you can scan up to 8 different fingers with the wizard for a single pass, but I think you would have to scan each finger perfectly afterwards to match the way it was scanned into the phone to unlock it Since you can also store multiple fingers, why not just scan the two or three fingers you would use the most and get a more accurate scan possible with the 8 passes?

..

Does anyone have any tips for using fingerprint scanner?

Swiping is originally very bad idea. Samsung missed the point. In iPhone you press button and scan your finger at the same time. So, unlocking made by simple press and hold 1 second to unlock.
What did Samsung is utterly nonsense and inconvenient.

I suggest the opposite : Use all 3 in only one finger. This way phone unlocks only with one finger, but scanner has the best possible recognition.
Every time change the angle of the finger slightly, so to read the finger in every situation.
