I have noted that several folks have the same problem that I have... rear camera is no longer functioning, green "static" screen, front facing camera works
Have read that folks think it is a loose connection and it is not a software issue. I have all current firmware updates and have done factory reset. Now I have a RMA to return it for repair but I wonder if anyone has removed the back and has tried reseating the camera connection? I read a great thread about removing the back (at your own risk) .
Anyone try fixing the camera by removing the back and messing with the connection? thanks for your thoughts

I returned mine. I had the problem crop up once earlier in the month. A reboot fixed it. But last week, it went completely green with interference like static. A reboot failed to recover as did a factory reset.
Asus recommended I return for repair. So, I'm guessing it is a loose connection. It makes sense. Better to have Asus do the repair/fix than me.
I am trying to avoid the return.. Seems like more folks are reporting rear camera issues..
I will keep hoping it is firmware and hope for an OTA solution or a take it apart/do it yourself solution. I am holding off for a little while before I return. thanks
I've read a few posts here with similar problems but the solutions (if any) haven't worked for me.
My wifi started to switch off intermittently. The "switch" icon in Settings would move across to the "ON" position but would then move right back to "OFF". Then after several hours the wifi would magically work again. Now it has stopped working altogether. I tried going back to GB including wiping data and cache then went forward to JB 4.1.2. No luck. I even tried GS2ROMNuke in between and Siyah kernel. I'm now back where it all started with WanamLite Clean & Fast & Pure Stock Themed 4.1.2
I opened the phone and checked for internal battery leakage but there was only a tiny amount and that was still on the battery itself, none on the circuit board.
At this stage I have just about given up. Has anyone managed to recover from this situation?
Of course it happened just 3 months out of warranty

Hey bro, sorry to hear about your problem. Have you tried testing the Wi-fi after installing a new ROM without updating or changing the stock kernel?

I think I have... not 100% sure though. Might go back to stock and try again though. Such a PITA... I was going to upgrade to a Note 3 and pass this S2 on to a family member. :crying:
Success!
I'm sorry to resurrect a long dead thread.
I just wanted to let you know I finally fixed my wifi issue. The problem was (as in many cases) the battery near the wifi chip, leaking. Although I had previously opened the phone and cleaned the PCB with isopropyl alcohol, I hadn't noticed that the track between one of the resistors and the wifi chip, had been eroded. I scratched some of the covering off the track and tried to measure continuity to one side of the resistor but got an open circuit. After clumsily soldering a piece of fine wire from the resistor to the scratched piece of track, wifi was restored.
I really can't believe it. I had previously inspected the board close up and thought that no erosion had taken place. But now after taking some time (and some beer) I found the fault.
Some feedback for Samsung... you *****es! How can you fit such a weakness to, what was, your flagship phone? This issue has hit so many users. I have read many many posts here and on other forums complaining about wifi problems with the SGS 2. Unfortunately for me this fault occurred when I was a few weeks out of my 2 year warranty
This was not an easy soldering job. I am fairly good at fine soldering but attaching a wire to a SMD resistor so small was really difficult. It may come off in the future but at least I now what and where the fault is now.
Once again, sorry to resurrect the old thread.
FYI the resistor that was affected was the one that sits by itself at right angles to the other 4. Unfortunately it is nearest the battery.
I've recently come in posession of a DX with a malfunctioning G-sensor, that is, sometimes it worked without the cover on, but upon replacing the cover / pressing the back of the phone, it stopped registering any information.
Sure enough, i opened it up, and inside there was a component loose on the motherboard, which fell off / apart when I tried to solder it back on.
(view the attached pictures)
Now, my questions are these:
- is that small SMD component related to the accelerometer/g-sensor
- which component is it (I think i can BARELY make out 'P1' in writing, but i don't have sufficient magnification to know for sure)
- can it be ordered somewhere
The phone seems to be working fine without it so far, everything except for the g-sensor, that is.
It is a very annoying thing though, and I would love to fix it if possible.
Did You have solved this problem? Unfortunately my motherboard is damaged exactly and i can not find any electronic diagram.
unfortunately, no... maybe it's not even that component, because fully disassembled it seems the accelerometer works sometimes, but as soon as the motherboard is touched / bent in a particular way it stops working.
i'll live with it until i run the phone into the ground, it's not that much of a hassle really.

Hey XDAers,
Device details:
Model: Samsung Galaxy S2 (i9100)
ROM: Cyanogenmod 9 (at first), Cyanogenmod 11-20141115-SNAPSHOT-M12-i9100 (now) with gapps-kk-20140105-signed installed
Kernel Version: CWM, 3.0.64-CM-g4ca83ff [email protected] #1
Baseband: I9100XXLQ6
I'm really at a loss of ideas here. A couple of weeks ago people started to complain that my voice is quiet / distant when I speak with them. My first thought was to clean out the mic hole which I did, and it seemed to help a little but the problem remained. A week or so later there was no sound from the mic anymore. Luckily I have a friend's old S2 for spare parts, so it was time to get a-fixin'. So far I've tried:
Cleaning out the microphone hole with a needle
Switching the whole screen assembly, complete with the USB-board and thus also microphone from the spare part S2 (as the screen on mine was cracked anyway)
Switching the antenna cable connecting the USB-board and the "motherboard" from the spare part S2
Switching the back plastic (the one with the mic hole, camera "glass" & screwholes) from the spare part S2
Wiping the phone completely clean (factory reset, wipe data, format system partition) and installing a new recovery and a new version of Cyanogenmod
After switching the screen I found that while a call is active, the screen stays dark no matter what. Pressing the power button doesn't open the screen, whereas pressing the Home-button will bring me to "desktop". As soon as I navigate back to the call however, the screen goes black. Thus I have been unable to confirm whether I get sound into a call if I enable the speaker mode during a call. In an effort to fix this, I swapped in the front camera/light sensor part from the spare part S2, but it did nothing to change the situation.
I might be missing something, but to me it is a mystery at this point. I have switched the actual microphone, eliminating hardware fault at the mic. I have switched the cable I see connecting the board with the mic on it to the main board, eliminating fault there (if it is even related, as I don't know whether it is, just switched it to be sure). I have completely reinstalled the software side except for the modem (with which the mic worked with earlier anyway), eliminating software fault.
What am I to do?
Hi, I have a problem with a Honor 10.
Since August it started to restart randomly, I just replaced the battery and I just did two factory reset but the problem continues to manifest even in the configuration screen.
I would exclude the faulty power button, since before rebooting it usually froze on the activity I was performing.
Any ideas?
Thank you!
Test power button with ohm meter.
It was doing this after the reset with just it's factory load? No 3rd party apps loaded?
Try reflashing firmware.
Maybe be a mobo failure.

I really don't think is the power button because it reboot even in idle on the table, and i saw that if i put it on charge it reboot instantly.
I have this problem even in the configuration screens after the factory reset, indeed i've must configured two or three times because of that.
I'll try to reflash the firmware, then i'll wait for a new battery i ordered a month ago.
If it will be still broken i guess is a mobo failure.
I have a question: i didn't flashed a smartphone before, and i was asking myself if this reboot problem can mess up with flashing, bricking the phone. Can it be possible?

Yeah if it interrupts the flash that won't end well...
If you can return it, do so... otherwise...
Before you go flashing nuts try to determine if it's a hardware issue. Check ribbon cable connectors... and that switch.
Firmware shouldn't become corrupted unless there's a flash memory failure or it was a bad flash to begin with.
Does it not do this is safe mode? 3rd party app if so.
If it does it when in the boot menu it's likely hardware.
If so it may be just a failed battery. Try with charger connected to see if this alters the behavior.
If you don't feel comfortable repairing it, let a good tech do it for you. I always remember my first mechanical alarm clock disassembly... it didn't go well

It reboots even in safe mode!
It would seem a hardware problem, possible that I bought a new battery already damaged?
It’s been a few hours since it works good after charging it to 100%, it seems that it starts to reboot towards 50%.
I wanted to flash it also because before doing the factory reset, it automatically installed some "stock" apps by itself, I refer to some games that Honor automatically installs at each factory reset, every time I uninstalled them, after some restart they reinstalled themselves.
It was a weird issue but looks like fixed with the factory reset, so now i only have the reboot issue.
I am so desperate that I would like to try the battery of my Honor 10 (the one with problems is that of my girlfriend), I would not buy another battery since I have to be delivered the one I ordered from a month.
It may be the battery, they can fail at any time.
It's rare for new ones to fail but it happens.
Use a firewall to block auto updates or installs.
Karma Firewall works well but its valuable logging feature doesn't work on Android 10 and higher, but it still will block apps.
Update: I just bought another battery and the problem persist.
Now im sure is not the battery so i will flash it very soon no matter what.
I have been having the same problem as you guys have since last Christmas (2020), when my phone was 18 months old.
I switched phone and gave the Honor 10 to my wife for Coin Master and the problem persisted.
However, two months ago the battery started to swell and surprisingly the problem went away completely for about a month. But as it swelled to the extent of pushing out the screen the problem returned a month ago.
Thinking it was possibly a battery/battery connection related issue, I changed to a new Pisen battery last night. Sadly, the rebooting continued but only for 2-3 times today.
So it is probably an issue with the board itself.

The battery failure may have damaged the mobo or perhaps it was preexisting.
Check ribbon connector pins for damage. Look around for visible solder cracks. Try pressing gently on the mobo with a pencil eraser with device powered on to try to find the area. Check ribbon cables too by gently moving them.
One of the most likely places for a failed solder joint are the BGA chipsets. The many solder pads are under the chipset, inaccessible.
Press gently on them to try and verify this. A hot air station (and skillset to use it) is the only way to repair this type of failure.
Any battery swelling is a failure, replace it asap.

As I said, battery has been replaced with a brand new one. Therefore the swelling issue is fixed.
Don't have the skill set to use a hot air gun or to solder so this is it for me.
Quite disappointed by the QC of Huawei as this was my first Huawei phone. I have been using Xiaomi since my first smartphone and never had an issue like this before.

My point was a mobo failure is generally a game over event.
I run strictly Samsung's as I like their UI and have become familiar with them. Of course in 2-3 years that could change if Samsung keeps dropping the ball.

I understand.
That said, Huawei did replace the MBs for out of warranty customers in mainland China as a good will gesture.
Too bad that policy did not extend outside of China.

Maybe see if they'll discount a mobo for you.
Not free but it might sweeten the deal.
Or write it off and move on.
All my Samsung's have been long lived with replacement batteries being the only repairs.
Another reason I like them.
In my case it was sort of dumb luck especially when choosing the first Note 10+. In this case they did live up to their hype.
The S4+ lasted over 5 years and still boots up.
I had the random reboots going on for weeks even at night, also bootloops sometimes .
I tried a lot of stuff but i got my phone going again for 2 weeks now without any reboots.
It might be just pure luck but this is what i did last time:
Did a complete reset of the Phone ( everything gone )
I changed simcard to other simslot (i think this made the difference, atleast for my phone)
No apps from Meta (You dont want any of their **** anyway )
ill keep you posted

Put on performance mode (might not be it, but details mather here, today is first day without performance mode, no issues so far)
No apps from Meta (again because details mather, might not be it, i had random reboots all the time, but when i was using instagram or it was still running in the background , it was real bad, You dont want any of their **** anyway )

Hey guys, it seems that I solved the problem by bringing the phone to a Huawei service center, they performed an "operation on the motherboard".
Actually they changed the battery with an "original" one for 60€ (the one I had replaced cost 10€ ), then when the problem obviously came back they did the repair on the mobo at no extra cost.
I guess it went well.

Did you had any reboots after the motherboard change?
I got the same issue with my Honor 10. Tried every trick that I could think of, but nothing seems to help.
What I noticed, that sometimes when it restarts it does get very hot in the area near the camera. (not sure exactly what component it's there but it's something on the motherboard)
I'm thinking if it worth doing this motherboard change. (as it seems to be a design/component issue if there are so many that have this problem)

No, no reboot at all, but I noticed later that they rolled back to Android 8.0, so I’m thinking that they didn’t fix the motherboard, but they actually found a workaround by downgrading the OS.
I’m afraid to try to upgrade to Android 10.0 for this reason, I don’t even know if I can do it considering the new Huawei policy of flashing and stuff, but my girlfriend is ok with that so I let it go.
I can confirm that even now, on each task (TikTok scrolling for example), it gets very very hot in that point near the camera, my perfectly still working Honor 10 instead does it only on intensive use of the camera.
I hope this information can help you with your Honor 10, I suggest you go back to an older version of Android if possible just for troubleshooting.
If it persists, the motherboard is probably faulty and you need to replace it, I guess...
