I've recently bought LG G3 D855. Sadly, it seems to be damaged in some way. Battery seems to be drained too quickly and the phone gives wrong information about it often. It's crashing randomly, but usually after booting the system. It's rebooting after 15-30 secs after start of the system until wi-fi, bluetooth and FM radio stop working. After this, factory reset and switching bt and wifi on and off in safe mode seem to fix the problem temporarily. From what I know, switching to other battery make wifi problem permament. I've been reading about similar issues and I still don't know anybody who had the same problem and what could be the cause of it.

You can ty purchasing a new battery..... Seems to be a big g3 issue now that she is aging....
But this device is also known for similar hardware issues try to fulll charge and operate device while on charger see how it works if all is good you need a battery if it still highly acts up more than likely hardware issue. If thats the case I would try to return it

When I try to turn on bluetooth, the icon and text indicates that the system is trying to turn it on. However, it never actually turns on and after a few minutes reverts to indicating that BT is shut off. This problem used to occur sporadically and sometimes seemed to be cured by rebooting. However it is now at the point that it just won't turn on no matter what. I did the requisite googling and found nothing very definitive. It looks like I may have to do an exchange on the unit but I would rather not go to the effort of unrooting this unit and rooting the replacement.
Any suggestions of things to try beyond what I have indicated above?

Are you using an experimental ROM or stock rooted?
Jedi Mind Trick XI (although the problem has been growing worse and has happened across the last several JMT versions). I will give a stock rooted ICS a try.
I just tried a stock rom and the problem persisted.
I have the same problem
I have scoured the net looking for an answer, any answer, to this problem. It seems that a few people are having the same issue. But before it is ever answered, some dip$#!t always jumps in and says "I have the same problem, my phone won't connect to my car." Then the conversation goes off into other people that can't connect their bluetooth to their car or their headset- or their cat... That is not the same problem!!!
I cannot turn my bluetooth on unless I soft reset the phone. Even after I've gotten the bluetooth working, if I restart my phone the bluetooth turns off and when you try to turn it on, it says "Turning on Bluetooth..." It cycles for about a minute and a half and then goes back to "To see devices, turn on Bluetooth."
I bought this phone on Amazon for what appeared (at the time) to be a reasonable price. Since then, I believe that I have read at least one of the seller's post about bluetooth not coming on (no proof, just an educated guess). The seller probably got rid of the phone because noone could or would give an answer to this problem. Heck, it's possible that every post that I've read so far is by someone who owned this phone at one point or another. :silly:
I am sending this post to XDA because even the adminstrators on android forums say that you guys are the smartest and most responsive forum available. (Okay, they didn't say smartest- it was implied). Please help me resolve this issue.
I rooted this phone the moment that I pulled it out of the box. In other words, I don't know if the bluetooth issue is caused by the root, or if the previous owner didn't root the phone and also couldn't get the bluetooth to work. I believe that, because the phone is rooted, I should be able to remove and reinstall the app that bluetooth is based upon.
I am not a techie, the only reason I know anything about root is because I was complaining to someone about my old phone and how all of the bloatware that seems to constantly run eventually kills my battery. He told me about rooting, and it was easy enough - the rest is history. In other words, if you ask me for more information- I promise that I can give it to you. Yet, have patience with me if I ask you a question that you believe that any person that has rooted their phone should know.
I really hope that you guys can help me without bricking my phone. I truly appreciate any suggestions or thoughts on this matter.

I may have figured out what is going on, although I can't understand why it is (maybe someone more versed with processes can help me figure this out).
Using Titanium Backup, I first froze the two bluetooth items (Bluetooth Share and Bluetooth Test). Of course, that didn't remove anything, but I wanted to make sure that I could. Then I wanted to see how Bluetooth Share would react without Bluetooth Test. I unfroze Bluetooth Share.
I was then able to turn on and off Bluetooth fine. I restarted the phone and Bluetooth came in just like it did on my old phone. I guess I want to know:
1) Is the Bluetooth Test the cause of my problem?
2) Why is it there?
3) If I uninstalled it, would I experience a major hiccup?
There is still the possibility that this was simply a fluke, and very soon I will go back to the old bluetooth soft reset problem.
There is, however, one distinct difference between this phone and the last and may be the "drop out" that everyone else seems to be having. I have a Chevy Malibu with bluetooth in the stereo. On my old phone, when I started the car and got going, the word "Bluetooth" would appear on the digital display for about 10 seconds, which means that the vehicle detected and connected the bluetooth pairing. Yesterday, as I was driving in the car, every 5 minutes or so, "Bluetooth" would appear on the digital display.
This leads me to the conclusion that Bluetooth is dropping out and being picked up continuously by my vehicle. Does anyone have any thoughts on this? I'm okay with that as long as when I am talking to someone for more than 5 minutes I don't have to keep calling them back. I simply want to know what you guys think about this issue.

I am beginning to think that the problems I have had are related to the condition of the battery contacts.I have several third party batteries with contacts that are somewhat damaged from the pins on an external charger that came with them. I seem to experience a variety of problems when I try to use them.my original factory battery seems to work most of the time. I have several new Samsung batteries on order and will post again if they seem to solve the problem.

i had the same problem and it started with JMT so I switched roms countless times and the problem kept coming back. It would work for a little bit but when i turned it off it would not turn back on. I decided to go back to stock to see if the problem was still there and it was gone. Since then I have rerooted and once again flashing diff. rom every other day and bluetooth works just fine.
Well it seems no answer was found. I'm having the same issue as stated above. In my case, my bluetooth (custom ROM) keeps trying to turn on with the message "Turning On Bluetooth" until I soft reset the phone, after that it works fine.

Was having bluetooth crashes for months using CM 10.1 on a T989 (no custom kernels)
Would crash anytime I tried to connect to car BT audio, or would simply not start up.
Flashed this yesterday.... and no crashes!
http://forum.xda-developers.com/showthread.php?t=2174100
For flash: Wiped dalvik/cache, flashed, fix permissions, reboot, start BT, deleted all devices, re-add.
No BT crashing of any sort for 36 hours now.

Hey thanks! I switched to JMT JB4 and it's not happening (much) now, I'll try to flash it and see if it fixes something :good:
LG F400L (Korean Variant)
I've had random reboot issues before but very rarely. It only occured during turning on the wi-fi and making a call at the same time.
2 days ago I went from Cloudy 2.5 (L) to Fulmics 5.0 (M), restored all my apps and my settings, then after a day, the bootloop issues started to occur. Sometimes it works and I'm able to use the phone for 1-2 minutes but then it would start bootlooping again (NONSTOP). So i thought the problem had something to do with the ROM so I restored my backup, went back to the Cloudy 2.5 ROM, same settings but SAME ISSUE.
But I found out that, it works when it is plugged in (charging). Even I load it with a lot of apps, no problem, but as soon as I remove it from being charged, it would start bootlooping.
I just need to know what could possibly be the issue?
BATTERY? (Replace the battery)
ROM? (Flash the original Kitkat via download mode)
or somethings else..
and would it help if I post a log?
Thanks. I am in desperate need of an answer
I think your going to need a new battery. Bootloops on 2 rom that have no known bootloop issues and only happening when unplugged from the charger sounds like a faulty battery that can no longer supply high enough voltage or current. A new battery will most likely fix your issue.

Hi everyone,
I'm having serious problems with my Wi-Fi on my Samsung Galaxy Note 3 Neo (SM-N7505). Whenever I click the button to activate the Wi-Fi, the icon goes from grey to a dull green (darker than the bright green which signals that a function is turned on), as it does when it's trying to turn itself on. Problem is, instead of turning on, it just stays in that state for a few minutes before reverting to grey. This has gone on for a while, and I've already tried several possible solutions which I found after online searches. I don't think it's a hardware issue (see point 1 for the reason), and I really hope it isn't, because my warranty has been voided due to rooting, so I can't have my phone replaced or repaired unless I pay for it (which I can't at the moment). So, I'm basically ignoring the possibility of hardware failure and trying every possible software solution, hoping one of them will work, otherwise I'm just stuck with no Wi-Fi. These are the fixes I've tried:
1) Take out the battery while the phone is on, wait a few seconds, then put it back in and boot the phone up. This used to work when the problem first presented itself a few months ago (which is why I don't think it's a hardware issue), and I've been since using this method to fix it whenever it happened again. But a few days ago, this method stopped working for whatever reason, so I was back to square one.
2) I tried renaming the data/misc/wifi/wpa_supplicant.conf file, which seems to have worked for some people, but not for me.
3) I tried updating the version from Kitkat to the recent Lollipop, hoping that would fix it, but nope.
4) I tried deleting practically every single app one by one, hoping that one of them was interfering with the Wi-Fi somehow, but nope.
5) As a last resort, I tried a factory reset, but not even that worked.
This is basically the long and short of what I've tried to fix this... I might've skipped a few of the simpler fixes I tried (for example, I just remember I tried disabling "Smart Network Switch", which seemed to do it for some people), but the big stuff is all there.
I'd really like to get my Wi-Fi back, so if anyone could help me fix this thing I'd be really grateful!
Thanks in advance to anyone who will bother to reply.
same problem dude
Same problem...wifi and bluetooth not working...pls help us
Same Problem for me, Initally it works fine even after updating Official Lollipop update (OTA), but after few months now wifi & bluetooth are not working for me. And finally faced battery drain issue for past few days. Battery goes down upto 20% per hour even in idle condition. Then i rooted & installed Note Rom & even after i face the same problem. Is there any way to fix?
Few days ago my phone began to shutdown either immediately or after a short freeze of the system. This happens in many situations, although mostly outside/when I'm on the move (I tried disabling GPS but it didn't help). Usually when I switch it on again it either shutdowns just as the lockscreen appears or doesn't work at all until I remove the battery for at least 10 seconds. The latter sometimes helps and the phone works properly for a couple of hours and the whole thing start over. I tried clearing cache, restoring factory defaults, changing the software completely (Fullmics, LineageOS) but nothing helps. I made sure that this is NOT battery related - I have a spare one and it's all the same.
I'm not sure whether the issue is hardware or software related. Here are my suspicions:
Why it might be a software issue:
- Just before the phone shut down for the first time I noticed that the upper part of the display stopped working - I simply could not pull down the notification bar. I rotated the screen and noticed that the same thing happens to the menu buttons which obviously replaced notification bar in the upper part of the screen. Eventually it turned out that this is not a defect of the screen and that part of the screen simply froze. After reboot it worked normally for a while and then froze again. After changing the software the problem seems to be gone.
- When I'm in recovery mode (TWRP) the phone usually is stable, it shut down only once or twice
Reasons for hardware:
- For a couple of months now the Wi-Fi is not working properly. It disconnects and whenever I try to reestablish the connection it goes into "Saved->Connecting->Saved". Maybe this is just the next step towards the graveyard?
- It's about 6 months since the warranty has expired
Have you experienced this and/or have any idea what's going on?
EDIT: With time it was more and more difficult to turn the phone on and keep it running and right now it's not turning on at all.
EDIT 2: I made it run again. TWRP works perfectly but once I reboot to System it shuts down almost immediately.
Nobody has any idea?
I'd guess it's the battery.
When I bought my G3 in Oct 2015, I had random reboots aswell, nothing helped (turning off mediascan, restore kdz via LGFlashtool 2014 etc.).
So I went ahead and bought another battery (7000mha) from ebay.
Never again suffered from those annoying random reboots
(Inserting the old battery, makes the reboots reappear, so that is postivie proof for the battery thesis).

As I wrote above, I have two batteries and the problems exists with both of them.
In that case try this:

Regarding your battery: You didn't only get "original" batteries ? I have a third party one... All original ones I had so far failed me...
Hello. I have Samsung Galaxy A3 2017 and have a few issues with it. First thing is battery life. After upgrading from Android 7 to Android 8, battery life significantly decreased! I even know the reason why it is happening (it decreases on standby mode. If you will remove SIM card or go to the Airplane mode, battery life is great) Probably many of you know about this issue? - Do you know how to fix this?
Another problems started about an year ago. Firstly, we were not able to turn on WiFi. This is also known issue on Lineage OS as I know, but this phone is still running its original Android 8. After few months, we could not turn on Bluetooth as well. After that, I tried a factory reset and that is when things got worse! After factory reset, phone was still not able to turn on WiFi and Bluetooth and plus it was restarting over and over again. During these restarts, you can not turn off your phone. If you will push the Power off button, it will simply restart the device. After a long time it stops restarting and you are able to turn it off, but Wif and Bluetooth are still not working. If you will turn off phone then it still starts restarting again and again. Now I have noticed that it shows antenna when there is no SIM card in it. Even signal strength is changing. Of course if I am trying to call or go to the settings, it says that there is no SIM card inside.
Please, could you help me to solve any of these problems? I have cleared partitions, made factory reset few times, wrote latest firmware for this model using Odin but none of them fixed anything.
Can I downgrade to Nougat? or should I try some custom ROM? If yes, which one?
