[Q] S4 i9500 buying tips - Galaxy S 4 Q&A, Help & Troubleshooting

I'm planning to buy a used S4 through a local website that offers a space for people to display ads for their phones (something like Swappa), but the problem is that :
- I have seen many fake products which looked exactly the same and even have TouchWiz on JB. What's more confusing is that most of these products have a printed valid IMEI number.
- used phones might have hidden problems with their sensors, or hardware in general even if they are genuine.
Questions:
01- I though I might compare the valid printed IMEI with the one I get when dialing *#06#, but I'm not sure if that number can be faked as well, can it?
02- Is there a systemic way of checking the sensors, cam, microphone, wifi etc by an app or something similar?
03- I think a benchmark tool like Antutu's can help to see the exact specs and compare them to the original ones. Can some of you take a screenshot of the exact specs as they appear in Antutut Benchmark or Android System Info.
04- How to know if a genuine S4 has been flashed before if it has an unrooted stock rom at the moment of checking?
05- Any advice on what to look for when examining a used S4?
PS: I will have physical access to the phone before buying.

Im not sure about the answer to these questions
but I can help with this

The Device Info tab of the same Antutu results you sent. It's on the top right; just click and send a screen.
And the same goes with Android System Info; install the app and send me a screen of the System tab. It's the second tab from the left.

have fun

Here are some codes that access various functions of the phone.
Most useful:
*#0*# - this will give you access to a test mode, where you can try various functions (cameras, speaker, display, sensors)
*#06# - to compare the IMEI displayed by the software with the one on the phone

well,you can check if your phone is genuine or not simply by using this app
https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo
if your phone is fake samsung it won't detect at all
second use this app to detect your hardware info and sensor
https://play.google.com/store/apps/details?id=com.inkwired.droidinfo
i always have this 2 apk stored in my sdcard so i can install and check the phone if i'm buying 2nd hand phone
P.S:i've been using these method since i've been scammed once for buying fake samsung galaxy s4 because it has fake antutu app

Conclusion
I searched a lot and here's a systematic test.
*#06# (dial it on the phone itself)
to get the IMEI number and compare it to the one printed on the package and the warranty certificate if any is present.
Droid Hardware Info and Phone INFO ★Samsung★ (apps from Google Play)
use these two apps to check the hardware specs (like processor, number of cores, GPU, ram, etc)
Diagnostic Menu *#0*# (again dial the number on the phone itself)
and test all the items
Connect to a laptop to check if it's read properly.
Use a Micro SD to check if it's read properly and try to copy a couple of small files to it.
volume down – power – and home to get to download mode it should say
CURRENT BINARY: Samsung Official
if Custom appears somewhere in current binary or system status, the phone has been flashed before.
Check the battery look and weight and connect charger and see percentage/min.
NOTE: There's a faulty battery batch whose serial starts with BD1 you can find more info in this thread
Check the hand and headset buttons and their buttons. And rotate the 3.5 mm jack while playing some music to see if there's a problem with its socket appearing as distortion in sound.

[Q] Device diagnostics (benchmark/stress test)

Hi guys!
I'm starting a company in Brazil similar to Square Trade and Asurion in the US. So, before a user signs up to one of our protection plans, we need to remotely verify whether the device is fully functional. We already have and app that does part of that (the user takes a photo, press some buttons and does some other activities so we can verify the device).
However, there's still some terrain to cover. I was thinking about a stress test that would make the device freeze/reboot when the processor/board is faulty (like these devices do when people try to use heavy apps/games), some network tests (wifi and 3g/4g) and battery tests (Android already reports some stuff like health and temperature but I think these are not reliable). Do you guys know about some way to do that? I searched for an open source benchmark engine to no avail, so the next step was to ask here given you guys are always making awesome software/tweaks.
Any help is appreciated.

[Q] accelerometer

Hi, I want to ask something. I have a problem with my accelerometer. So in the gpsstatus, it always shows g ~ 0.49 (https://www.dropbox.com/s/ylqclmxp71s1085/Screenshot_2014-08-25-23-49-06.png?dl=0)
I am not sure since when it happened. Then I download the system monitor, and only the Z accelerometer that gives wrong value (I guess it shouldbe close to 9.8??). Also from *#0*# looks like the Z value is wrong.
What is the number in your devices?
Is there anyway to reset/calibrate this number, specially without rooting?
Thanks!

Anyone here know how to fix this problem?
there could be only 2 possible causes for this: software or hardware.
For software issue you could reset the phone to factory or even wipe it clean and reload stock firmware to see if that helps.
If it's a hardware then the only thing I could think off is to make sure all the connectors are clean and make good contact, but I don't remember if sensors are on separate module like vibration or cam modules or are they build onto motherboard. If they are on separate board then check connectors and look for replacement, if they're on MB, then no connectors to worry, but fixing it gets more complex.
I can't remember ever seeing calibration for accelerometers, sorry.
What issues do you have, outside of showing wrong on gps status? Is it worth the trouble of fixing it? Samsung repair service is probably best bet, if that's an option.
ps
my gps status shows 0 unless moved, so there is something wonky there

[Q] Fake?!?!?

I accidentally bought a fake GS5 like is shown in this video. https://www.youtube.com/watch?v=5lc6dQb5cF8 There are many things wrong with it.There is a model number mismatch on the hardware and software, the hardware is European(ms-g900f, the software is for the Chinese unicom version(sm-g9006v). The recovery is chinese and has no download mode. It won't get LTE, the fingerprint scanner doesn't work, it's very laggy, the flash for the camera is different, and the screen is loose on the corners. Also, the back is cheap plastic instead of faux leather like the real one. I know I got screwed over, since the seller has since blocked me from his phone number. Am I just completely out the money, or is there anything I can do to make this a decent phone again? Is there any market to be able to resell it? Thanks. If you need any more information about it let me know!

The attached picture is what it says when use *#06# to get the imei. When I use the imei that is under the battery it says the number can't be found.
Ok, then it's a china fake…

When you buying Samsung I would recommend to try it with http://www.imei.info/ or take laptop with you and connect to KIES or run download mode. No download mode or no knox = not Samsung. GS5 has plastic on back not faux leather as note 3 has (mine is plastic blue and is genuine) Fake unit is worth nothing maybe about £80
Can I do anything with it or make it work? Or is it totally just a junk phone?
Junk. I would not recommend to sell it to someone as Samsung.
Take his number to the police. Can't guarantee it will help but it's worth a shot.
Try and perform the steps written here to confirm if its a fake or not

Buying a Used Samsung Note 4 - Any suggestions?

Hello,
I am going to be buying a used Samsung Note 4, specifically: N910W8.
Is there anything specific I should look for in terms of functionality, or common issues this device might have?
Thanks

There are no common issues with the phone. However if you are buying used phone you have to look for these things:
Fist of all, if someone is selling his/her phone, find out the reason why selling, there might be 2 reasons, faulty phone or he/she is upgrading his/her phone.
Phone's Condition --> external condition (such as screen has scratches or side scratches etc.)
Camera: Check Camera is working fine - both front & back ( take some pictures)
Sensors: Check phone's sensor is working, some of the phone's sensors sometimes not working. For Screen / Sensor and other software related functionalities you can dial this number and check sensor, phone's color and screen, if broken internally or not. (*#0*#) - dial this from Samsung phone dialer.
Check Speakers are working fine, make call and check both the speakers.
Regarding Software related: it depends upon the ROM, which ROM you are running on your phone. If stock ROM, phone should be working fine, if he has ROOTED his phone and running custom ROM, then you will find some bugs in custom ROMS.
There are no such software related issues with all Note Series, they are awesome phone.
[*]Also, check if phone is repaired before or not ( you can open the back panel (battery door) and check the screws, if they have scratches then phone was opened and repaired.
Battery: Check the battery, I will tell you the procedure: take out the battery and put it on table & rotate it clockwise or anticlockwise, if it's not rotating, means battery is OK, if continuously rotating, it means battery dead, or about to dead, you need to replace it.
This is what I knew, & I have shared with you.
Good Luck!

test it with a sim and sdcard both inserted.
some note 4's may seem fine, but will suffer freezes, crashes, reboots, and boot failures when both cards are inserted because the motherboard is dying.
make sure you swipe it completely so you don't get busted with somebody else's dirty/illegal porn LOL

Alt firmware for (possibly fake) DZ09 smartwatch?

Hi! I got a DZ09 smartwatch and it's missing a lot of stuff. Is there a way to run normal (I efully functional) firmware on the smartwatch? It doesn't seem to support notifications, vxp apps, or remote camera viewing.
I typed in *#3375# into phone app and got
Software V:
MX31D-COB-DZ09-7789-HSD-RQ-GL6113-ZH-V06.929-20190327
Also if anyone has the software to edit firmware or the MRE SDK, let me know bc I can't find it
I tried to do what your attempting here, but there are "geniune" dz09s, "fake" dz09s and many more, with different chipsets and different firmwares, despite all looking the same. I tried to find a firmware for mine, which was apparently a "fake" one, but couldnt. So i didnt get any further than that. Make sure to check which processor your watch has, you can do this by opening the back cover, removing the battery and then removing the back screws to remove the plastic bracket. Now you will be exposed to the motherboard, one of the chips on the board will be a mediatek one (the processor), read which one it is off of the label. I suggest doing it physically rather than through software as software can be faked to show a superior model.
I may be able to do that tomorrow but this is the model if it helps https://www.walmart.com/ip/Wintekd-...ports-Run-GSM-GPRS-SIM-4-Color-Gold/379234992
Also in the menu u get hy entering *#3646633# it says
<CHIP TYPE>
SC6531BA
apparently there's posts on here involving a DZ09 that has that chip
Again, you're on your own with this one. Maybe someone else will come round t ohelp, but I highly doubt that.
So far I found a lot of stuff from hardware version in that menu: SC6531_BAR
I'm not sure about custom firmware yet tho
Um any1 help.
I've got a fake dz09 too . It doesn't boot or charge. I mean. It does charge. But when it's on portable battery it keeps disconnecting and connecting. I have a electricity meter. When I put it in the battery pins, when the portable battery starts charging it gives for half a second a wave of electricity. Help?
