    My Galaxy S II reboots once a day - in avarage - What kind of problem do I have ?
    Is it hardware or software ?
    Facts:
    - Model: GT-I9100
    - Android: 2.3.5
    - Baseband: I9100XXKI4
    -Kernel: 2.6.35.7.I9100XWKI8-CL616395 root@DELL149 #2
    - Build: GINGERBREAD.XWKI8
     
    I bought the phone 23th. of november 2011
    I installed a 16GB MicroSD card
    I installed all the apps that was using at the old phone (Galaxy I9000)
    Phone was't able to run 24 hours without reboot.
    By reboot I mean: A sound, the little 5 seconds Galaxy-movie, and asks for pincode...
    No systematic in the reboot. Not a specific place, not a specific time, not by doing something special.
    It never reboots when it is "open". It's always when it is lying on a table, or in my pocket.
    ==========================
    OK. A factory reset. No apps installed, minimum of configuration.
    Phone still reboots once or twice a day
    =========================
    OK. 16GB MicroSD disabled
    Phone runs for 60 hours, then reboots, Then it runs for 22 hours and reboots
    =========================
    Right now: WiFi disabled... It has been running for 14 hours... waiting
    Update by 18dec: After 25hours I forced the tip of a plastic tooth-stick under the battery. After 60 hours I installed all my favorit apps, and it is still running... (88 hours)
    Current conclution: Hardware - Bad implementation of battery-connectors...

    Update by 3jan2012: Nope... Still not ok. Two reboots around x-mas and yesterday... once again.
    I have been talking to Samsung, and they does not (officially) admit that the S II has a reboot-issue. They advice me to go to a repair shop, since the phone is fully updated and that they don't have more advices to give...
    ========================
    More info:
    Two colleques has the same phone, and they never reboots.
    The one is a lower Android version: 2.3.4
    The other is the same except Baseband: I9100NEKI2
    If I return it to the shop they will send it to Samsung Repair, and after 10 days I will get it back. Or maybe a new one...
    Pls. give me some advice..
    Regards in advance

    Some GS2's seem to have a problem with the battery being slightly loose.
    Try wedging a small piece of paper between the battery and compartment at the end opposite to the terminals.
    no harm in trying anyway.

    My phone seems to reboot everyday ever since I had updates to 2.3.5

    On 2.3.4 on my Latin American model (not KI4, an older version), my phone would crash every few minutes if I dated to move one app to SD (among other issues). Returned for refund and got a UK model.

    That model came pre-loaded with 2.3.4 (KI4) and ran beautifully. I then used Odin to go to 2.3.6 (KK2) and got random reboots about every other day. I reverted back to KI4 and have been fine. On that note, I really don't care if I get 2.3.5 or 2.3.6. I'm happy with KI4 and curious about the eventual ICS update.
