Did you ever wonder if your device is really waterproof but do not want to find that out by dunking it in water?
Here is a test which uses just the phone and it's service mode (or any barometer app).
1. dial *#*#7378423#*#*
2. go to "Service Tests"
3. go to "pressure sensor"
4. slightly compress the phone using your thumb and index finger by pressing on the display and back
SLIGHT PRESSURE. No Berserker mode please! This is not a crush-your-phone contest!
--> if all seals are intact the pressure should rise. Your phone with intact seals is a closed system. If you compress the volume the pressure goes up as a result. If any of the seals is compromised pressure will not rise.
Note: pressure will decrease automatically - that might be a result of the sensor adjusting, it will not go back to it's original value until you relieve the pressure.
credit for the original idea goes to User Alik from the German Android-Hilfe.de forums

this only works with a pressure sensor (barometer) - does the Z2 have one?

yes z2 have pressure/barometer sensor.
then you can use this test for Z2 as well
It works. Pressure rise when pressure applied with closed flaps.
Once I open a flap and again apply pressure then nothing happens. Pressure stays the same. So, mine is waterproof. Yeeey
I tested,
start value: 1009
compress and hold: rise to 1020 and back to 1009.
release: fall to 1005 and back to 1009
It looks like mine has fault?

I get the same reading. it starts at 1014 and goes all the way up to 1022 when i touch it with my thumb, but it automatically goes back almost instantly with my finger stilll pressuring on the screen. If i open the flaps, then the sensor's reading wont change. I'm clueless!
Excellent! Thanks for the tip! Everything is perfect with my device!

It means it's working cause pressure gets stabilized
Same here pressure equalizes after a second. So its not really tight?

That's what I wondered, if the pressure goes back to normal that means it's escaping somewhere? Unless it's stretching somewhere else in the phone I guess? But mine does the same, pressure increases then normalises, then drops lower when you let go before returning to the original value. So that means it's water tight?
wow never realized Z2 have this sensor
i remember my Z1 didn't have one, it just said "This feature is not supported"
For me, too, the pressure rises, then falls back to the original pressure. Then if I let go, the pressure falls, then rises back to the original pressure.
However, this is not a meaningful test, although it gives at least a vague indication. The seals are not intended to stop the phone being able to equalize atmospheric pressure with the outside world, they're designed to stop water coming in. Most likely, when the phone is squeezed the increase in pressure pushes the seals out just ever so slightly, leaving a gap through which pressure can slowly correct itself.
A slightly more meaningful test would be to compress the phone with the doors open, then seal the doors with the phone still pressed, and then let go so that the first thing you're doing is creating negative pressure in the phone, not positive pressure.
well maybe thats not a proof ... i bought this device a week ago and from day one i submerged it three times into water to test is it really waterproof or not and yes it has done the job ...
but just trying that pressure test in normal atmosphere it equalizes after a second
while underwater i tested and the pressure increases but doesn't equalize.. so thats the point of waterproofing..
its not air proof !!
hope that could be useful for anyone ... just don't panic if in normal air atmosphere the pressure goes back to normal
My pressure just stayed at 1005. I pressed the screen and I pressed the back nothing changed I think it's because I changed the back plate recently...

Hi everyone
I have S4 i9505 I got it second hand
I noticed that the auto brightness not working
I make sensors test and her is screen shot for result
Another scresc shot from galaxy sensors app (3rd sensor says waiting)
Any idea how to solve this , is it SW or HW issue?
It is hardware issue
The hole whre you insert handsfree get some blower that blow air with pressure
Blow it properly hope this work

(ALMOST 85% SURE)
Try comparing your phone with other S4's with smallest differences.

Hello.I hear a little noise from my earpiece like small creak.it's not always happening.As I haven't any warranty..Is there any working sound mod for my earpiece at least to lower the bass so the creak to be minimised?

Have you tested using another earpiece to rule out it's caused by your earpiece?
no dude I mean the inbuild earpiece that I hear the others (not the speaker).when I lower the volume it's ok...

Hi
i got 2 brand new S8 G950FD and i got the same problem with both
tge magnetic sensors "compass" keeps losing calibration.
this becomes very annoying when using Google maps onfoot everything is upside down .
recalibrating the sensor is always successful but for some reason it doesn't stick for long even when using high accuracy location settings
I'm not sure if the problem is with Google maps compatibility with the S8 or with the sensor itself
anyone having the same issue ?
does the calibration rest automatically when going to the sensor app (*#0*#) ?(even though I'm going to the sensor app becomes the map is upside down )
thanks in advance

i think it's the same with all S8 devices
Third row from top, middle button. It's called sensor on my device.

My FD doesn't play nice with one of my cases, as it has some metal in the back of the case. Compass won't even calibrate when the case is on. Makes sense though.

make since but i don't have any metal in the case, and it does calibrate
I've got exactly the same problem. I never thought that a protective case could be the problem, however, I'm using the Samsung original clear case and it does recalibrate...but it's very annoying because you can't rely on your compass, it will abandon you without warning.
Has anybody found a fix to that? Is it hardware related?
Hi, I've just bought my a5 2017 from Amazon, I came from loved redmi note 3 pro: I notice fingerprint is way way way worse! Recognition rate 20% since the first boot up, one finger better than the other at least. What's wrong? Looking the light reflection I may think there is a sticker on the home button so it takes all the "hand grease" but I didn't manage to remove it and stopped, fearing to damage it.
Any help is appreciated

Light reflexion is normal. Delete fingers saved and reconfigure. During fingers configuration, change your fingers positions until 100%. The multiple positions of your fingers are all saved. It's important for recognition rate

Thanks for your reply. Some days ago I tried instead to delete all the fingerprints and to try using the same "portion" of skin instead of saving all the possible angles like I did in the previous phone: things improved, 20% right finger and 40-45% left finger. At last I surrendered and changed the password to a simpler pin for the (fast) right hand and tried to configure three identical fingerprint for the left hand: 60-70% recognition rate if I "strike" the right portion and position. Almost acceptable. Should I send back to amazon for replacement? Are yours normal and working instead or is a model problem?
