@rachels42 yes, for ADB you need to have your phone plugged to your computer with USB.
Then you install ADB software on the computer side, and enable USB debugging on the phone.
You can do a logcat to display the system log, which is the journal where we could look for hints about what caused the crash.
It might work if you logcat right after the crash, if the crash is not too much severe, but it would be more accurate if you were already logging while the crash happens.
@jaymanu Iāll see what I can do. Hopefully will have some time this weekend to work out hot to install ADB and display the system log. Then hopefully will have a crash when Iām by my laptop. Do you have any idea of the maximum time window I would have after a crash to do the log?
Well if you remove your battery, unfortunately it will reset the phone and delete its internal log.
You might anyway try to use ADB on your phone while its in the frozen state. Thereās a (small) possibility that the underlying system could still respond while the user interface is crashed.
Hmm, if I manage to restart by doing a long press on the power button does that also reset the phone / delete the log?
We canāt know without trying. But if the power button responds, thereās some hope that you might be able to talk to the phone via ADB while itās frozen, without even having to reset it.
I had the same issue without another phone (not fairphone). Some module crashed everytime i connected to an unknown wifi network. The faulty module tried to analyze captive portals. I could disable the module and fix it.
Sounds promising. Iāll try and set things up soon. Might just take a while as Iām very much an amateur at this type of thing, so working out how to set these kind of things up requires a lot of googling for me and rather a lot of trial and error!
I have this too sometimes, usually when scrolling. But the other day, something very unusual happened.
We were in the car (on the way from Vienna to Schladming), with two FP2ās sitting in our pockets, doing nothing in particular. At some point on the way, we tried looking at our phones and realized that they were both frozen and needed their battery to be removed. So, something (not user-triggered, we had the phones in our pockets, of course screen lock was on) made them both freeze.

ā¦were both frozenā¦
[/quote]Funny story.
I think you both passed an NSA surveilled cell mast, and the FP2s defended themself from beeing spied 
Just another disappointed user that has random freezes. I havenāt actually discovered reboots, but the phone just goes black. Doesnāt turn on anymore, even when pressing 10 sec on power button. It just vibrates and the red LED lights up. I am able to restart it after 10 minutes or so, it then re-optimizes all apps.
To me this seems like a hardware problem. I have experienced blackscreens at full battery charges and at low ones, however, when Iām able to turn on the phone again and look at the battery usage, there is a time-period that where no battery usage is not shown at all, like in this picture:
Anyone has an idea what this means?
I moved your post here as you donāt have reboots. Even though the topic title says ārequiring removal of battery to restartā I guess itās the same issue, because the others probably didnāt wait ten minutes like you.
Hey,
maybe the problem could be caused by a loose battery. I created a topic for it:
Battery pack liberates from holder -> FP crashes and rearrangement necessary
Hmmm, my FP2 has the same problem. But this morning it is getting worse. After putting the battery back itās works for a few seconds. After I enter my password. Then the screen is frozen.
Now itās wants to reboot. With this error: E:canāt open /dev/block/platform/msm_sdcc.1/by-name/misc (permission denied). Maybe someone knows what this means and hopefully this is the error for freezing my screen. Iām gonna try ADB when Iām home.
Can somebody help me? But a phone that doesnāt work at all is very disappointing.
Greetz,
Bart
My fairphone 2 crashes more times the day and flicker at several brightness . when we get an urgent update?
Today my FP2 crashed about 5 times. So far thereās one consistency: it happens when the screen is off. Thereās no way to switch the device back on, other than removing and reinserting the battery, or pressing the power button for more than 10 seconds.
The phone just lies on my desk, so no (heavy) movement that might affect the battery position. The battery or device itself donāt appear to be getting hot. The phone does not have any apps installed that have ads, or any other out of the ordinary apps that I had not installed on my FP1.
Iāve cold reset the device twice already (about two months ago), no change. Iāve tried different batteries, no help there either. Switching off G4 didnāt work, meaning it didnāt fix it.
It happens both while charging or unplugged.
At one instance, the LED was flashing, indicating the phone received a message (that I later could confirm). Yet, there was no way to switch the phone on. I therefore conclude the phone still works, but just isnāt responsive to the power button. I have no indication the power button is malfunctioning in ānormalā operations.
Upon every restart the phone language is set back to the SIMās country, which is also quite annoying.
Iām very curious about when to expect a new firmware that could fix this. I found myself thinking itās a bit weird, to put it mildly, to charge more than 500 Euros for a device that doesnāt work.
edit: Sometimes Iām lucky and the phone works like a charm for a day. While typing this post, the phone froze again, which brings us to a score of 6 for today.
Hi!
It has happened to me twice: finding FP2 with black screen and not being able to do anything, just taking the battery out to be able to restart again the phone.
Today I upgraded the OS version, and 30 minutes after, while I was using wifi, I opened Google Maps and turned on the GPS. I left the wifi and started to walk using maps without internet. When Iāve taken the phone again (after 5 minutes) it has the black screen and without any evidence of live. I removed the battery and then I could restart it.
Iām using 2 sim cards with 2 Android users and both are running in roaming mode.
Is there any easy tool to have a log running in the background?
Thanks for your help!

I also have to restart my FP2 about 1-3 times a day. Iāve never had it freeze during use, rather Iāve always picked it up with a blank screen and it wonāt unlock. Sometimes there is LED activity still. It always restarts with a long (10s) press of the power button. I canāt see any pattern to it. Iāve tried uninstalling some apps that I though might cause it but it hasnāt helped. Hoped the update would help, but I think if anything itās worse now.
Iām also experiencing the same issues with the black screen and unresponsive FP2. The notification led flashes so the phone is still working. Have to hold down power button for approx 10 seconds for it to reboot. Happens around 1-2 times a day.
Iām using the FP2 as a test for my company to see if we should purchase more of them. So far itās the buggiest phone Iāve had. At this price point I expect more. In this state it feels like a ātake 3, pay for 2 productā at a gas station or somethingā¦
my phone chrashes twice while google maps was used as navigation system and hooked up on a car usb charger
Happens to me probably once every 2-3 days. Worse after the update. Usually Iāve just pressed the power button to standby the phone, then I realise I needed to check something, press the power button and it doesnāt respond.
Leaving it does nothing. If I long press the power button for 10-15 secs it buzzes and I see the Fairphone white on black screen and it reboots (fairly quickly) as if it had just been turned on.
Occasionally I see it locking up with the screen on when Iām not interacting with hit. Exactly the same, but the screen is on and it doesnāt power save off. Itās as if itās the same bug, except sometimes itās randomly happening vs happening when I power off the scree with the power button
