LG G4 Completely Crazy

Hello guys.
Today I woke up to some strange events happening to my phone.
I left my phone turned on while I slept, as usual. When I woke up, I noticed that the phone auto brightness wasn't working at all. It was stuck at the minimum brightness and it wouldn't change even if I pointed the phone at the sun. Rebooting the device did not fix the issue.
After a while I decided to pass some music from the computer to the phone with the cable. The cable kept disconnecting the phone, like it had a bad contact. I had a really hard time to put my music on the phone (lot's of phone and PC reboots).
Then, when I finally put the music in it, I plugged the headphones and tried to listen to music, only to be presented with lots of white noise mixed with the music. The white noise "changed" if I moved the cable thingy. Again, reboot didn't fix the problem. I plugged the headphones in my computer and they worked just fine.
I left the phone alone and went on my business. Some time passed and I noticed that the LED light had a permanent green light that would just not go away. I managed to fix this by rebooting in safe mode and booting back to normal mode. This seemed to fix it permanently since it did not happen again.
Now, I tried to use my GPS to play some Pokemon Go. While I was playing I noticed that I was not able to use the button that made the map point in my direction. I installed a Compass app and to my surprise, it said that I didn't have a sensor for it. My compass seems to be gone.
I went ahead and did a factory reset. It did not work. Every single of those issues keeps happening.
Then I tried to use the "refurbish" option on LG UP. I'm always getting "Error: Error Code = 0x2000, Can't decide current device mode
Any suggestions? My device is the European with stock firmware. My S/N begins with 604. I really didn't want to send my phone to repair, I know it will take ages. RIght now in my city it has been really hot (43ºC in the shadow), but there's really nothing I can do about the heat. This never happened with my Galaxy S4 Mini. Help?

That sounds crazy!
Any possible water damage?
Try going to the service menu and testing everything from there. This is done by dialing a code in the dialer app.
So for the international version it is *#546368#*815#
For the Dual sim version it is *#546368#*818#
I assume for the NA version it is *#546368#*811#

Hey, thanks for the reply. And I told you it's too damn hot here so the only water contact the phone might have was with my sweat.
As for the tests, the phone failed Barometer, something called TL wrong and the proximity test. The GPS itself was fine tho

In that menu, try going to Device Test and choose SAAT. Then tap on Service Menu Manual Test and then tap on Key and next tap on Test then Cal Start. This will help you recalibrate the proximity sensors. Use your phone after the recalibration to check if it works properly.

I guess it's time to send it for repair. At least my humidity thingy hasn't been triggered.

My Nexus 5x doesn't turn on at all, what can I do?

So this is what happened, a couple of days ago I was using my Nexus 5x normally when it turned off. I tried to turn it on but nothing happened so i tried to turn it on whith the power and volume buttons it turned on but the screen froze when the loading the colored dots. I tried to turn it on again with safe mode and it worked but the screen froze again after a couple of minutes. Now this freezing thing happened every time i tried to turn on the phone.
A friend told me to wipe the cache partition but nothing happened. the told me to factory restore it, the I was able to turn on the phone but started to reboot some times or just froze when starting, so another friend who knows about android phones told me to do the wipe data/factory reset and thats when the phone turned off while wiping the data, now the phone doesn't turn on at all. I saw the red light like when the phone is out of battery so I started charging it but the red light started blinking a couple of times then stoped.
One more thing, one of the times I turned it one it looked like it was everything ok except that the finger reader wasn't working and there was no google imprint menu so I restarted the phone and de finger reader was working but the phone was rebooting spontaneously. This happened before trying with the wiping the cache and doing the factory reset.
Thats basically what happened, is there something I can do?
My phone is the LG Nexus 5x 16GB whit android nougat 7.0

Hi, complete n00b here. I found this post when searching for answers about my own Nexus 5x. I ended up contacting Google. I got the quickest "we're sending you a new one" that I've ever seen. This is what they told me: "You are not the only one it does look like there was an update and Nexus 5x phones were affected. We will get you taken care of with a new one with the update already done to avoid any complications in the future like this."
FYI, mine was under warranty and I have Google Fi. YMMV

lenovo p2 stuck in boot made is charger

My Lenovo P2 had 20% battery charged. I plugged the charger and after making sure that fast charging has been started, I left. After 2-3 hours I came back with certainty that the battery would have charged 100%. But unfortunately what I faced was a dead mobile. I unplugged the charger and re plugged it and found a white display with the note Boot mode is ‘charger’ . Now every time I connect charger I face the same note (sometime repeating sometime once) and cell phone does not go beyond this state.
How to fix it?
I am waiting for your response please.

try holding power and volume up and connecting cable just before you press the buttons to go into bootloader mode with the charging status shown...this is the only way i charge my P2..sometimes it doesnt work the first time...so make sure you connect cable just a split second before pressing vol up and power button...try it

In 1st attempt nothing happened. In 2nd attempt the white display with the said note "boot mode is charger" didn't appear. Red led is blinking and screen is black.

pressing and holding the power key + volume down key gives the following page attached as image. click this link

the soft button "start" faced the power key so when i pressed the power key the same loop resumed
click this link

1) press power button for 10mins
2) try to boot into fastboot and from there boot into system
3) fastboot flash twrp and flash any ROM of your choice. Or fastboot flash stock

Thanks for your kind advice. I have done it already . Stock rom was tried. But it stucks while flashing systemchunk4.img . So finally admitted in hospital i mean submitted to the company Lenovo for solution....

should charge
the image that you sent earlier of the bootloader is actually charging the phone...just leave it like that and see if it charges...i hope we talking about the same issue here.

No bro. Its not charging rather its a restart loop. Any how thanks for your time and reply. I have submitted the phone to service center. Let C what they do.. !!

Touchscreen works only sometimes, screen flicker

Hello,
I have a problem with a Galaxy S9. It started acting up today and not registering touches.
It took me many many tries to access the recovery because it just wouldnt let me power down and all possible volume down /up, bixby and power combinations didnt seem to work and the screen often just stayed black while giving vibrations. So I finally were able to access recovery after 20 tries with vol down, bixby, power and then quickly change it to vol up.
Now comes the questions what I should do to troubleshoot. The recovery menu seemed pretty laggy as well.
I wiped cache and restarted, but no improvements. Touchscreen works every 30th press, screen sometimes flickers.
Issues:
Touchscreen doesnt work (every 30th press approximately)
accessing recovery is a game of luck
screen flickers (sometimes bright flashes) I attached a picture of one of those seizures
random vibrations
Last resort is a complete wipe but I'm hesitant because it seems likely to be a hardware issue and replacing the screen wouldn't require the need to delete all data.
I hope someone has an idea. What confused me most were the issue accessing recovery.
Thanks and Best Regards.

It's a issue with samsung. They dont know what it is. Either the screen or hardware. If it's under warranty that's your only option. Look up samsung green screen and you'll see

I'll check if the warranty is still valid. I dont know if you can help with this question as well:
The screen has had a little unobtrusive crack in one corner for a while, I suppose when they do a hardware repair they will have to replace the screen as well and charge for it? Or is it irrelevant in a warranty case?
Thanks and BR

If its damaged in any form you will have to pay

Hardbricked, not even edl mode. Hardware issue?

Friends,
First I apologise for the WOT.
Background:
My OP 3 died on me last week. It was working at 3.00 pm, I went for a nap and at 4.00 pm woke up to see my phone with a black screen. My volume down key isn't working from even before. I use Havoc OS, TWRP, rooted with Magisk and no modules. Since I am bootloader unlocked, I use the startup screen using the volume up key to navigate between recovery, fastboot etc because of the volume down key not working. My device had roughly 70% charge when it died. Fortunately I had completely backed up my data from the phone to the laptop the previous week along with a TWRP backup.
What I tried:
Connecting it to the charger starts the screen but after the OnePlus logo it starts bootlooping. So not charging even if left on the charger for extended periods of time. Starting with the power button results in identical behaviour. While connected to the charger, from the startup screen, I am able to choose the bootloader and sort of boot into bootloader. But if the charger is unplugged, the phone dies. So not able to use fastboot.
Using the charger, from the startup screen, I am able to choose Recovery (TWRP) but after the OnePlus logo, the TWRP screen flashes and then the phone starts to bootloop. If charger is disconnected, phone dies. So not able to use recovery too.
When trying to hold volume up button for 10 seconds and connecting to laptop, the 9008 driver flashes for a second in Device Manager and vanishes. Phone is not otherwise recognised on laptop even as a charging device. When trying to charge on laptop, the phone behaves as it did on the regular charger ie. bootlooping.
If the MSM tool (version 3.0 and 4.0 as Administrator) is running (with the start button clicked) when I connect the phone holding the volume up button for 10 seconds, it starts the download and then (in one second) in the Tool, I get the message "Try Firehose communication handshake". Then the laptop freezes and I can switch off the laptop only by holding the power button down for 8+ seconds. I have tried both USB 2.0 and 3.0 ports with the same result.
The fact that the laptop freezes makes me suspect a short somewhere. I have ordered a new OP 9 Pro and it was delivered today. Now is there anyway of resurrecting my OP 3 without changing the motherboard?
Thanks in advance for any suggestions.

I remember such behaviour from my OnePlus One back in the day. I solved it by trying numerous different drivers, A LOT of trial and error. But considering it's a 6 year old device and you were still using it as a daily driver, I'm afraid it's not software – as you've also hinted at. I hope it'll be a fun hardware project though! Not my cup of tea ^_^

Update:
Visited OnePlus service center. They initially said that it was only a question of flashing the software and asked me to wait while they flashed it. One hour later, I was informed that an IC in the motherboard seemed to have shorted and that they no longer stock the motherboard of OP 3. Even if they had stock, I was not going to buy it since it simply is not worth that much money to revive a 6 year old phone. Using it as a paper weight now.
End of story.

Sorry to hear that, mate...
