Loss of Signal on Samsung Epic 4G Touch

UPDATES:

12/7: Sprint has finally released via OTA EK02 which should hopefully fix the LOS issues. Samsung also released the kernel source today - and from the looks of it, they also fixed a bunch of other issues Sprint won't admit to (or maybe they didn't know about....).

http://community.sprint.com/baw/community/buzzaboutwireless/phones-and-devices/samsung/samsung_epic_...


9/29: Shane_M has responded from Sprint with this message:

"The loss of signal issue is an official known issue, Sprint and Samsung are aware of this issue and it will be addressed in a maintenence release. This information is posted on our known issues board and should be accessible by any care or technical support representative you speak with."

------------------------------------------------------------------

This is a growing problem - did a quick search and didn't find anything in here....

The issue is the phone will go into "No Signal" mode randomly and the only way to get out of it is to reboot the phone.  Happens when in sleep mode; with and without wifi on; standing on your head; kissing your wife. Here are the messages spouted in Logcat when it happens:

  • I/TelephonyRegistry( 2716): notifyServiceState: 1 home Searching for service...    Unknown CSS not supported 0 0RoamInd: -1DefRoamInd: -1EmergOnly: false
  • I/StatusBarPolicy( 2835): onServiceStateChanged-S:1 home Searching for service...    Unknown CSS not supported 0 0RoamInd: -1DefRoamInd: -1EmergOnly: false
  • D/Mms/SmsReceiverService( 5897): [Mms/SmsReceiverService][SMS]Receiver handleMessage : Action =android.intent.action.SIM_STATE_CHANGED
  • D/PhoneApp( 2874): - state: DISCONNECTED
  • D/PhoneApp( 2874): - reason: radioTurnedOff
  • I/TelephonyRegistry( 2716): notifyServiceState: 3 home null null null  Unknown CSS not supported -1 -1RoamInd: -1DefRoamInd: -1EmergOnly: false

Anyone see a problem here?  SIM_STATE_CHANGED?  radioTurnedOff?

Actually, I was teasing him about his chosen username. 

Probably, the apostrophe would not have been permitted anyway - but he still misspelled "you're."

Dude you're such a noob...   My username rocks and special characters, like the apostophe, obviously weren't allowed.

YourKiddingRight1,

Your name does rock, but too bad you misspelled it.  YoureKiddingRight1 would have been more correct (without the apostrophe).

So how do we get our "MSL password"?

Those are outstanding speeds.  I never get anywhere near that performance.   Are you sure you're not connected via wifi?

Best I EVER get is 3.0 down and 1.5 up and I'm in New York City.

Download connect bot

click the ssh dropdown and pick local, put a nickname

type getprop ril.MSL

the readout is your msl, comes in handy for when you're doing late night dev and can't get ahold of sprint, or just don't feel like lying lol.

credit goes to jlear3   on xda devs

Looking at the items we can change with this info do we believe changing these parameters will help with any of the issues being discussed here?

Panzer06,

     Not to my knowledge that I have seen, because XDA developers would have came up with it by now.

Oops your right. I just tested it again w/o wifi and it was 2471 download, 602 upload and 159 ping.  So that's still not bad tho.... right?

Those are respectable numbers and more than sufficient for most mobile data needs.  I'm lucky to get 400K down and 115K up on 3G.

Cheers,
