In the past I had stability problems with my Jolla several times and sent it in for repair / maintenance twice (the first time because it apparently shredded its file system due to the frequent crashes and would not even allow a factory reset any more, segfaulting on any btrfs operations).

Since the last repair, the phone worked pretty reliable and stable - until yesterday.

Now it reboots immediately after establishing a connection to my mobile phone provider - i.e. if I enter the SIM PIN on startup, the phone crashes/reboots a few seconds after booting.

If I do not enter the PIN, the phone works - until I open the system settings and enter the PIN there, afterwards the network operator's name will appear shortly at the top of the lock screen (where the date is displayed) and the phone will crash / shutdown immediately after...

Did anyone here experience anything similar and is there anything I could do besides sending the phone in for a third time? I really need a working phone in about one and a half week and would not get my Jolla back.

Installed OS release is 1.0.8.21.

(Edit: Fixed typos and added installed OS version.)

I had this quite often by the past. For me the solution was following: 1) The paper trick (3-5 sheets of paper), 2) Do not switch on simultaneously mobile data AND wifi. Always switch manually; not very convenient but my phone is now reliable.

Anyway when I have some rebooting problems (in my Jolla this happens after I try to connect several times to a weak signal wifi) a solution that works with me is to shout down the device and remove the battery for 10 minutes. After that phone restart working in the right way.

@Hubb5: I already read that thread, and tried to clean the battery contacts, but to no avail. Also, currently the phone is not rebooting randomly, but actually always as soon as it connects to the cell phone network...

May be Btrfs balance as described here could help:

Root and home disks full and causing various problems

This does not seem to be the problem in my case:

[root@Jolla ~]# btrfs fi show              
Label: 'sailfish'  uuid: 4b9a7c4f-83c2-49be-b2b7-6fe67cc12eae
        Total devices 1 FS bytes used 2.63GB
        devid    1 size 13.75GB used 4.75GB path /dev/mmcblk0p28

Btrfs v0.20-rc1
[root@Jolla ~]#

Plenty of space for new blocks or extends or whatever btrfs calls these chunks... ;)

It probably was a hardware problem of my unit.

I had an unusable phone every few months and sent it in for repair three times, where it was always only flashed.

Before being totally bricked the device always showed file system issues.

After the third RMA I asked for a replacement device which I kindly received back then. This was in spring 2015 and the replacement Jolla has been running fine and without (unusual) issues ever since... (Keeping fingers crossed...)

My solution to the same problem (immediate shut downs abroad when trying to establish data links, often when answering or setting up a call in home network and while roaming): I left the boat, bought a different device. Sadly, the Sailfish OS and concept were promising, but a device that is not usable is not usable. I had no problems since, and I never have been in a situation where I could not read the screen (even in bright daylight).

It is a power problem -- and Jolla does not care to provide a solution that will eliminate the problem once and forever.

Sometimes I think I have bought a different Jolla than others. I have no problems with reboots, I've never had problems with WLan, I can read the screen outside, even if it is a sunny day...

Yes, it may be that there are Monday devices. But if so: Why not does Jolla simply replace the devices that have problems? Instead they try repairs that remind me of woodoo. See Answer https://together.jolla.com/question/66454/what-to-do-since-yesterday-jolla-reboots-immediately-when-connecting-to-cellphone-network/?answer=66518#post-id-66518 for example.

Yes, I am heavily disappointed!

Same issue here! I have sent phone in for repair in august because of sudden reboots. Then it works two month. Now Jolla reboot multiple times a day again. Actually I have next reqeust open, to send in for repair. Hopefully they will take this issue serious, and fix it permanent this time. This installed small plastic thing called "bumper"is not a solution and I can not imagine how they think so :(

Are you guys on the IRC of Jollamobile? I sometimes look into the chats discussed their and the devs really want the logs of your phone if you have this kind of problems with some kind of a description of what you where doing at the moment of the reboot.

If you can post it here it could help a lot I think. Believe me, they are trying to solve it.
