Every device asks for the pin/pattern/password on first boot, it's the same on Apple products. As for the fingerprint, I can hold my phone upside down and it will recognise it.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] fidorulz:
I dont get why a device would ask for a less secure mode of authentication when a more secure one is programmed

thanks for your info
[Samsung Galaxy S7 Edge Guides, News, & Discussion] lvnatic:
A fingerprint is not cryptographically secure and it's much easier to "crack". For example you get arrested and the police wants to search into your phone. There are many countries where the police doesn't need a warant to do this, they can just force you to put your finger on the scanner. This goes for thieves too, they can use force to unlock your phone. So a password or pin is technically more secure.

Edit: another big reason for this are the unfortunate events when someone can lose their hand or fingers. The only way you could unlock the phone this way is to hard restart it and use the backup password.

And it's not a very big deal, I doubt you restart your phone every few minutes. Mine for example has 5 days uptime at the moment.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Tonys7Edge:
U can assign your prints many times from different angles. As for having to enter the password from reboot yeah I found that less secured. My solution on mine s7 edge is having password lock on the SIM card so there's a double lock when ever my phone got a reboot.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] J.Biden:
I have registered two thumbs and two index fingers and the fingerprint scanner accepts them even if I scan them up-side down, so there might be something funky going on with yours. Delete your current prints and do it again. This time, don't just press the scanner in the same area, but move your finger so it gets your whole thumb, and also rotate your finger a bit while it scans.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] daddymikey1975:
I just rotated my fingers a bit between scans. Problem solved.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Faspaiso:
A read a few years ago that some hackers got into the iPhone when fingerprint was enabled. They could only get through the first lockscreen right after boot. I THINK that is the reason for the pin, as that is way more secure.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] the_scotsman:
Yep, it does work on all angles. But you should do more than one fingerprint profile, even for the same finger. When creating a profile, you need to move your thumb around to cover the whole area of your thumb, otherwise you won't capture enough for it to work on all angles.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] meyerweb:
1. Requiring a pin or password after boot is an additional security feature. How often do you power down your phone and then start it up again?

2. If you rotate your finger while setting up the password, the phone will recognize it rotated later.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] dave812:
In my experience, two of the same finger will drastically mess things up. Unlike the iphone, where it helps. Try with just one of each finger.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] dave7802:
I agree with the OP on the Fingerprint, But for me its not a issue.

All i done, was go into the finger print and added my same finger multiple times from every angle.

The Rotation of the finger was a issue ONLY when i setup my thumb holding the device properly.

I think it has more to do with the overall % of the Thumb area it was able to capture.

So rotating 90 or 180 may miss off 25% of your original scanned thumb, making it incomplete.

I added my same unlock fingers about 3 times, one of them uses just the edges of thumbs, the other uses the Flat part and Top

the over uses Flat part and bottom.

So when i press with my Thumb, it recognises my Half-pressed Thumb print, or even just the top segment.

The Eneter your Pin on Reboot is stupid, But would not suprise me if there is a Mod to alter this behaviour.

It was adapted from Apple i think, when they don't the first fingerprint release you had to do the same on apple on first reboot.

(It seems more secure on the fact if your drunk and unconcise someone can turn your phone on and access it with your hand)
[Samsung Galaxy S7 Edge Guides, News, & Discussion] maroc84:
A good password before allowing the fingerprint scanner on a restart is a security option to encrypt the storage. A fingerprint isn't that secure as you think. It was recently been proofed vulnerable simple by taking the fingerprint (eg. the fat film on the touch display) and print it. You just have to use magnetic ink.

http://hackaday.com/2016/03/11/finger-print-scanners-really-arent-that-secure/

http://gizmodo.com/how-to-easily-hack-a-smartphone-with-an-inkjet-printer-1763261331

Much more secure would be a vein detection fingerprint scanner. Besides the fingerprint itself it detects the individual vein structure and flow what 1. isn't noticeable from the outside 2. needs you to be present (and alive) ;)

BUT as said before: Different countries police is able to force you to give your fingerprint - This would be an issue if there wasn't an option to ask for the password (and pin) before encrypting the device on startup. The only what you have to be trustful is the phone manufacturers firmware. The strongest password is nothing, if the manufacturer failed with firmware.

This is indeed only just theoretical, because most people for sure haven't that much of a interesting contend on their phones.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] fredphoesh:
I find the fingerprint scanner to be completely rubbish with my thumb and ok with my index finger. I even programmed all four on the same thumb, all with the phone being held in the right hand, and must have "scanned" every part of my right thumb from several similar angles, so there is no excuse for it not getting it right every time, and yet, I would constantly be timed out 29 secs 59 secs, 5 minutes... VERY VERY annoying. So it seems my right thumb isn't samsung fingerprint scanner friendly (it's not like I do a lot of diy or wanking or something!!) Index finger is ok, but then it is not friendly to use as I have to hold the phone in my left hand to then scan my right index. I suppose I could use my left index but the point is I cannot use my S7e fingerprint scanner with one hand as the thumb does not work.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] dave7802:
A simple way to overcome the fingerprint

would be to inbuild a temperature control and only accept a fingerprint at the provided with a temperature of: 37 degrees Celsius

Again its still possible to overcome, It just starts getting expensive to be able to do so.

(Anything can be overcome, its just about how much time and money one may have)
[Samsung Galaxy S7 Edge Guides, News, & Discussion] J.Biden:
But what If I have the flu? What if I've been in the sun for a while, and the surface temperature of my skin is above 37 degrees? What happens during winter when it's the opposite?

Back to the lab I guess! :cool:
[Samsung Galaxy S7 Edge Guides, News, & Discussion] dave7802:
Actually would not think so, With some clever coding or even using the latest AI's

You could implement something easy enough.

Using something like current GPS and Weather to understand the conditions it may be faced with.

Understand when your ill your Temp does go up and down, but not a great deal and it would not be hard to implement the differences in the temperature control.

To be able to tell the difference between a human temperature and Synthetic, based on how quick the temperature is reached, how its maintained and pressure sensitivity

All your doing is adding a layer of security of Magnetic printers.

So instead of it costing around 500-1000 to bypass a fingerprint reader, its going to increase that by alot.

Making it less affordable for your average Joe.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] J.Biden:
Hahah, yeah so this is making a thing that's not that complicated, extremely complicated. The current fingerprint readers are secure enough (for now), so no reason to go overboard here :laugh:

Also, temperature is not a constant. It changes all the time, so temperature reading is absolutely not the way to go. Fingers, eyes, ears and toes are mathematically unique, in the way they're one of a kind on each person, and can't easily be faked. Temperature is so incredibly random that it would never work.

A reader that includes a capacitive surface that rely on the electrical properties of the human body to detect if it's human (like a regular touchscreen), is easier. That way, it needs to be a finger touching, and not a piece of rubber or paper. Maybe it's already in place, I don't know, and I haven't tried to unlock any devices using paper or anything.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] mathieulh:
You need to use a PIN because your phone data is encrypted and in order to generate the key (used to encrypt/decrypt your data) you need a static value (your pin) in conjunction with a seed (your phone's unique secret key), it is much easier to generate the AES key using a static value that approximated data configuration (which is not static) generated from one (or multiple) fingerprints (the sensor is a camera which takes a picture of your fingerprint which is then processed to generate data based on its unique feature, this data is then accepted within a margin of errors as the parameters are never strictly identical even when using the same finger, while using AES encryption algorithms however, you cannot use an "approximation" of the key/iv.

Once the device is powered on, keys used for data decryption are stored on volatile memory (if implemented properly, hopefully within a secure element) and cleared upon reboot/shutdown, which explains why the pin only needs to be entered once.

Even the best military grade bio-metric sensors have proven to be insecure and have been defeated on multiple occasions, sometimes using contraptions as simple as tape and glue, I wouldn't call it secure.

Then again nothing is fully secure, so the level of security you need depends on your uses, to me anything short of using a PIN secured HSM is inadequate security, then again this is cumbersome, not implemented in most phones/devices (including the Galaxy S7) and might prove to be too much of a hassle to most people.

---------- Post added at 05:01 PM ---------- Previous post was at 04:55 PM ----------

This is easily defeated using a real finger with fake skin (as, apply artificial skin on top of your finger), just saying.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] J.Biden:
Yeah, I know. I was saying how this wouldn't help.

[Galaxy S 5 Q&A, Help & Troubleshooting] amadoaramendiz1:
I wouldn't like to bother you people, but I'm really in trouble with my phone. It turns out that it was a little bit laggy, I was using omega Rom. So I decided to flash stock one with the new update 6.0. When I was on Odin I checked the nadroid erase option by mistake but everything was going on well. The problem is when my phone turned on It was literally crazy. The back and recent lights turn on and off like stars, and the phone is xtremely the slow. For instance, I can select an option like call someone it takes a few seconds and then it does it. The same with volume and power buttons. The weird thing is that sometimes it works like if anything happened. No matter the charge of battery.

Ah, and I did flash again the firmware. Not once, but twice. And also I flashed a 5.0 firmware and it was the same. All this zips were taken from Sammobile.

Finally, I drive my phone into a repair service, but they told me it was the display, but I disagree because why does it work sometime? Why when crazy nor the volume neither the power bottoms work?

Please help me, they told me the display cost about 200 dollars and well I don't think that's the problem..

Sorry if you don't understand my language isn't English.

Hi all,

Gonna install Artemis Touch 2.1 this evening hopefully... after been stuck with the WM5 02 provide.

I know I need to use the USPL to flash it, and then install the rom, but I was wondering is there anything else I need to do before I do it, I like bricks but not expensive ones :). I want to back up contacts; sms, email & that whole 9 yards, will PIM Backup do that job? from what I read in other threads I think thats the one I need but I'm a noob at this, also settings like the 02 sms; gprs & mms, will they also back up, or do you recommend I write them down first?

think thats it, soz for the questions but total noob who doesnt understand half the things you guys talk about right here :o

any help much appreicated...

JT
[P3300, MDA Compact III ROM Development] neilhhardy:
ok sit back and enjoy the ride :)

1. install SPB backup, great tool, just do a search on google for it.

that will back up everything for you.

2. run USPL and wait for it to finish.

3. the phone reboots, look for UPL and make sure the last digit is a 0, its something like upl=1.11.0000.

once your here, you can flash any rom you want.

good luck and if you get problems ask for help.
[P3300, MDA Compact III ROM Development] tildesley:
thanks neilhhardy;

1 quick question (ok 3 :) )

firstly; i guess i dont use the full backup option in spb backup, im guessing i want custom back?

secondly; how long does the whole process take?

thirdly; will the unofficial roms make the orbit any slower?

soz again for all the questions & thanks for the help!

JT
[P3300, MDA Compact III ROM Development] neilhhardy:
ok number 1, i always use the full backup and get a copy on the PC too ( just incase your sd card crashes out.

go and get a coffee relax a little and its done ( +/- 15 mins)

nope, actually there faster and better, Tom B&B 4.2 is running perfectly lots of nice features, Also Mesche's Roms are cool.

there the only 2 ive been playing around with.

if i were you and the first time flashing a new Rom, go with Mesche's Vanila rom 2, nice Rom with not so much software installed and also very very fast.

hope this helps.
[P3300, MDA Compact III ROM Development] tildesley:
thanks for all the advice neilhhardy, im now touch 2.1 yay :)

question though; is there anyway to add a wifi icon of somekind, to the quick launch bar at bottom of the screen? i dont like clicking the 'G' up top then selecting WiFi that way :rolleyes:

laters

JT
[P3300, MDA Compact III ROM Development] neilhhardy:
yes no probem, if you have battery status installed, you can choose to add on a tray bar, then you can have wifi icon, bluetooth icon and what ever else you want.

[Galaxy S I9000 Q&A, Help & Troubleshooting] KHazuya:
Edit: I solved it by going back to Stock rom, Android 2.2.1 Froyo. It didn't happen anymore, so it must be some software related issue which remained on the phone even after fully wipe including the OS. Now I will just need to root the phone again and flash custom roms on it.

Hi there,

When I bought my Samsung Galaxy S back then it came with Android 2.2 Froyo (or it was Eclair, don't remember), which I updated to 2.3 Gingerbread. Since then I flashed newer Android roms found on this forum. I never had any problems. So I had ICS (various versions), JB (various versions) and KitKat (I think I was on 4.4.0 and later on 4.4.4)

So up to Android KitKat 4.4.0 I used it on daily basis but after I got a new phone I didn't use it much anymore (I would only turn it on to make sure the battery won't die). But recently I turned it on, I can do things on the phone but when I leave the phone on standby it would eventually reboot on its own.

I tried installing an older version of KitKat. I picked one from an older date, which happened to be 4.4.2. The same issue happens there too. I just installed Android 6.0.1. made by Full Advance. and the issue happens there too.

My phone has an SD card inserted but no SimCard, anything else you need to know just ask.

I would like to keep Android 6.0.1 from Full Advance. It seems a fast and stable rom. It feels faster than the KitKat 4.4.4 I had.

I would be glad if the issue on the self reboot would be solved. I want to use this phone as a MP3 player. I really like AudioFX.

Any help appreciated, thanks!

[Oppo R7 Plus] celoxocis:
if you have root and could provide me with the output of the partition details I can build a TWRP specific for the R7 Lite. if it has not been done yet.

I will need information output of:

and

cat /proc/partitions

you will need to have root and switch to "su" in the shell before entering the commands.

Do you have some news on twrp for ps, your cm build etc?
[Oppo R7 Plus] celoxocis:
CM is still work in progress. I will be leaving tomorrow for a one week getaway. After that I plan to write a PDF guide for those with PS how to install TWRP as PS fastboot allows for bootloader unlocking.

[Oppo R7 Plus] celoxocis:
I know what DTB stands for ;) I can see that you are on Project Spectrum. The DTB for PS (Marshmallow) is different than that for ColorOS (Lollipop) there fore it is not working. The offical TWRP is based on ColorOS for the mainstream available. Project Spectrum is only available for beta testers. However "fastboot flash recovery TWRP. IMG" should work. To enter TWRP simply hold down volume-down + power button. When I finish CM I will release a TWRP with kernel+DTB based on Android 6.0!
