[How-To] Fix ring lag (SCI method)

[KSmithInNY]

Here's an old trick us cell phone junkies have been doing for quite some time which makes calls and texts come in faster. This has been a pain point on Sprint for a long time, some phones worse than others.

1) Call sprint CS and get your 6 digit MSL
2) On your keypad dial ##DATA# (##3282#)
3) Select "Edit Mode"
4) Type your MSL as the Service ID and hit "OK"
5) Select Advanced
6) Change your "Slot Cycle Index" to the value of 1 (explination below)
7) Press the Back button twice
9) wait for your phone to reboot

Slot Cycle Index (SCI) - You can tweak your Slot Cycle Index (SCI) to make your phone poll the tower more often. This makes your texts and phone calls come through quicker. This setting is a trade off between lag, most noticeable when receiving calls, and battery life. The default value on our phones is 2. Every step of 1 adds 1.28 seconds to the poll time, so at a value of 2 it is only polling approximately every 3.84 seconds or so (0=1.28 + 1=1.28 + 2=1.28 == 3.84). If you lower this to 1, the phone polls every 2.56 seconds (0=1.28 + 1=1.28 == 2.56). This won't affect battery life much in areas of good coverage, but may impact it noticeably if you're in a poor reception area.

Cheers!

adjusting the slot cycle is really not the (whole) answer. First you need to realize what ring lag you are getting and where the ring lag is.

Yes adjusting the slot cycle will cause the phone to react faster to the network but is that where the slowness is?

A SMS message probably won't have a noticeable benefit by adjusting the slot cycle, an incoming phone call? maybe but probably not and this is why I say this -

Adjusting the slot cycle only adjusts how fast the phone can react to an incoming phone call on the network, it DOES NOT affect how the phone processes that incoming call after being notified of the call and acknowledges the incoming call. For example the HTC Hero I had was notorious for its ring lag issue, adjusting the slot cycle wouldn't make any difference. When looking at the Hero's debug logs I could see the phone was notified of the incoming call but it took 12 seconds before the phone would alert me to that incoming call. Adjusting the slot cycle would make no difference in this scenario.

I have an LG G3 Vigor. Stuck in a contract. Not a good phone. The biggest problem is that it only ring 10 seconds. I read about Slot Cycle Index but do not feel qualified to adjust that. I have had AT&T change my ring time to 30 seconds. This phone still rings 10 seconds. What is going on? Neither AT&T nor LG will do anything about it. (AT&T did send me another LG G3 Vigor even after I told them we tried that in the store to no avail.)

Help?
