[Q] HELP! P900 WiFi Problem

Hi All, I have P900 which I bought about 5 months now, and all the sudden the WiFi is not working as it keep switching on and off automatically (problem which similar to S4 WiFi) and off all the time. I have been doing factory reset, and flashing roms. None of them works. Now I would like to try flashing the modem module just like S4 fix, but I have no idea on where to find those files. I would really appreciate if someone could give me some lead on this, or any other ways for those who have similar problems. Please help.

Same problem (SM-P905V)
I see that this thread is really old but I am having the same problem and I can not find anything on the internet to fix this problem. I bought a refurbished note pro from amazon last September (so it is out of warranty). This is my last ditch effort to try and fix this on my own. If I can't get any help then I will just have to send it to Samsung to try and repair it.
My wifi worked just fine for all this time then about a month ago I was having problems with the bluetooth not connecting. I ignored it at the time as I was going to work on it at a later date. Then about a day or two later it started working again.
Now about a week and a half ago my wifi and bluetooth stopped working. I have factory reset but still nothing. I can get the wifi to even turn on any more. Occasionally I can get the bluetooth to work for a minute or so but 99% of the time neither one works.
I hope that someone can help me with this and I can get it resolved without having to spend a fortune.
PS If no fix then what do you suggest as a replacement? I love all the features of the note pro. I like the stylist, the screen resolution, and the multi-window features. I need a big screen for my business. I use it for a slide show at events.

Bluetooth and Wifi have many components on mainboard, repair them is beyond anyone including professionals.
My suggestion is looking for a Note Pro with broken display or woking mainboard only on Ebay; it may cost around $120, more or less depending on luck.
Take out the mainboard is quite easy, only 3 screws at two speakers, I can swap the mainboard within 10 minutes.

Any SM-P900 ( wifi ) or LTE ( 905, 907 ) mainboard will fit to your existing tablet except rear camera ( LTE rear camera won't work with Wifi model mainboard ).

Since the thread is four years old, this is not really a follow up, but just a note in case anyone is having similar issues. Actually bluetooth + wifi repair on samsung tablets are possible for end user - if you are semi-lucky and broken components are not hard to replace items such as ICs. But first, be sure to rule out any OS level issue by flashing stock rom on the tablet. Then if the issue persist, then if you can locate service manual for the tablet in question, it comes with level 3 step by step instruction (and board view of components) on how to troubleshoot bluetooth + wifi hardware issues. Often the broken component is not the major IC itself, but discrete components such as capacitor, filter or resistor. In some cases issue may be fixed just by reflowing the IC itself with hot air rework station. So there is indeed good chance you can fix hardware issue with a bit of work and some cheap hot air rework station (such as 858D sold on ebay for $30 including shipping).
Ok the worst scenario is that wifi ic is bad and need to be replaced. Good news is that Samsung uses popular wifi ic, such as broadcom chip. And although it's a bga chip, it's quite small, making replacement using hot air gun possible. So will a lilttle bit of skill and luck, it's definitely possible to repair samsung phones/tablets with broken wifi hardware.

[Q] Warning: Camera Failed. Can anyone fix it?

I am having a huge problem with the main camera on my Sprint Samsung S5. Every time I try to use it, I get the notification "Warning: Camera failed." It was purchased on the release date (I think 4/11/2014). It was a known issue for Verizon and I think Sprint phones for this to happen but mine is having this problem 10 months later. I have cleared the cache, cleared data, wiped cache and dalvik, done a factory reset, installed MOAR 6.0, CM12, MOAR 2.2, removed SD card after having flashed a new rom (so no other apps could prevent the main camera from working), disabled the Samsung camera app and tried using Google Camera, and nothing has worked. Today I went to a cell phone repair store and the technician said he tried three main camera sensors and two front facing camera sensors (just to allegedly rule out a hardware issue) and could not get any of them to work. The front facing camera works in Google Hangouts but nothing seems to get the back camera to work. I don't even recall dropping my phone and there's not a scratch on it but one day the main camera decided not to work. It wasn't even after flashing a new rom. Does anyone have any ideas?
Thanks,
Richard

Samsung warranty
We received a service bulletin a while back about this specific issue and its a hardware problem . So your best bet is sending in to Samsung or depending on your carrier you can call carrier and they will swap it out for you.

Thanks for your reply Dhulqarnain. I have rooted the phone and tripped Knox so I can't send it back to Samsung and Sprint is requiring me to sign up for their protection plan (I think through Assurion) to take care of this even though it seems like it's a known issue. Do you have any other suggestions?
Thanks,
Richard

Same problem...inexpensive solution
I've had my sprint s5 for nearly 2 years now, and I recently started having the same exact issue. After extensive research I'm afraid that I must confirm it is a hardware issue. I'm in the same boat as far as knox, my friend...and that leaves repair as our only option. The good news is that it supposedly isn't too difficult to replace, it actually connects like a laptop keyboard, or an ipod hard drive connects (a ribbon type connector). It probably will be a ***** to get it connected, but the even better news is that eBay has our s5 camera from a few dozen sellers ranging from $6 to $15. :good:

Thanks Gmoney1234. I took the phone to a cell repair shop and they tried six different main camera sensors and two different front facing camera sensors and could not get it to work. So that means there's something else going on with it.

Replacing rear camera module

On rooted Developer Edition Ultra:
Is there any additional procedure needed after replacing the rear camera module? The phone has random camera busy/restart errors. Attempting to isolate apps via SafeMode was inconclusive. So, I decided to disassemble the phone and re-seat the camera ribbon cable - after reassembling, the camera works for a day or two - then the error appears for a while.
Thinking that it might be a failure of a camera component itself I replaced the module with a new one (bought from eBay) yesterday and when reassembled/rebooted - the new camera did not appear. I reinstalled the original camera which is currently working.
FYI - all ribbon cables are aligned, clips tight etc.
When I have some time I will reinstall new camera again and reflash with 4.4. Does anyone know if a new module needs to be 'initialzed'? My assumption was that installing the like component would simply 'work'.

Here is my experience when my rear camera started failing. The cause was from a drop, landed face down with a case, no visible damage, not a single scratch. After a few days, the camera start failing to initialize. I can get it to work by squeezing on the back case just right. Opened it up and started playing with the ribbon, taking the entire motherboard out, etc. Ended up replacing the camera and still the same. The cause I believe was a hairline fracture to the motherboard caused by the drop. I was still under warranty and Motorola replaced my phone no questions asked. I used the website so I never even spoke to anyone. So, that was my experience with this issue.

Thanks Johnny - that sounds familiar - my XT1080 took a hard fall once. Camera problems started after but I always attributed the issue to the move from 4.2 to 4.4. Camera is working well right now though I do have to restart the phone every day or so. Before I used to have to press on the phone back below the camera. Your symptoms are almost identical to mine.
The issue I had after replacing the camera was that the rear facing camera did not appear in the app after reboot - only the front facing camera. When you tried the new camera was it recognized immediately by the phone?
This Ultra D.E. is my 'daily driver' it does everything I need - it's out of warranty and sending it to MOTO for repair will cost $183. If I don't sort it out with another camera, I will assume that the motherboard is at fault (that of course was my next assumption). Thanks for confirming the problem.
I'll post a follow-up as soon as I either fix it or send it to MOTO.

It should just pick it up. There usually ins't anything you need to do. My guess is that there is some type of micro fracture, and when you installed the new camera it affected it just right, not letting android detect it. Try it again. Either that, or the camera you received was DOA, or has its own problems with the cable etc... hard to tell.
Try taking a good close look at the motherboard, maybe with a magnifying glass, see if you notice any small lines or breaks.

S6 Gyroscope problem

Hello guys. Yesterday I bought a Samsung Galaxy S6, the "normal" S6. I bought it from a guy, tested it 2 times everything fine but today I discovered that the rotation is not working properly. When i dial *#0*# and test the sensors, all pass but the gyro test fails. The phone doesn't have warranty, and I wanna know guys if you also got this problem and if you fixed it. If not, I could replace the gyroscope/accelerometer or what the heck is not working in a GSM service?
A friend told me that if the sensors are damaged then the phone can't be repaired. Please help me if you can. ?
PS: Sorry if I typed wrong.

If your friend doesn't repair phones for a living, then perhaps you should ask someone who does if it's repairable....

Changing rom doesn't solve it? I haven't tried this yet..

It is possible that it could be a software glitch. I had the issue with my ex-S6 Edge, I got it fixed by telling Samsung to reinstall the firmware for me.
I now have an S6, I used Samsung Smart Switch yesterday to reinstall the firmware on my phone. It fixed some issues I had along with less heat and better battery runtime. I suggest you do the same, it's worth a try.
Just be sure to charge your phone to 100% and use *only* the original USB cable from Samsung. You could end up with a bricked phone if you use third party cables, other users have ended up with such fate.

I have the original cable, but if I use it there are no chances of bricking it right? I did 3 factory resets already, and I cand replace the sensor with problems, it will cost me pretty much. I also have something with the camera. It looks like it takes whiter pictures, I think. I'm going tomorrow in a store to see another S6, to see if the cameras are the same.

If your phone isn't rooted, if you haven't tripped KNOX. Then you should be good to use Samsung Smart Switch to reinstall the firmware. I used it just about four days ago to reinstall the firmware on my S6. Solved many problems for me. It's worth a shot before replacing the hardware.

Camera obstructed

Anyone having issues with the flip camera?
Mine worked fine when the phone was new, but now it flips _almost_ all the way up, then complains about camera being obstructed. When I gently push it back/forward I cannot feel anything obstructing the camera.
Same thing when i try to flip it back down.
I'm not sure if one of the many OTA:s has caused this or some other degradation from usage..

The update that came today seems to maybe fix your issue.

No change unfortunately

Have you tried the recalibration option?

Hello, maybe the next firmware will help you WW_29.13.7.47

Are you using a screen protector with black borders? Those tend to trigger the sensors, which is why the flip camera thinks something is in the way

I ended up doing an RMA with Asus and they replaced the motor. I assume it had become damaged somehow. I was not charged for the repair.
