Tried and tested multiple times on 2 epics and the fix does not work. It sees up to 11 sats but won't lock on, good snrs of 20 to 30. Restart on both machines usually did solve the issue.

Because I find the peopel I have known for a long timw and who have a history credible.Sorry your response isn't credible. Why don't you post some rationale here? You yourself admit it works for 90% of users only.
cold start fix workign for 90% of users wh tried. Others maybe having other problems but workaround works fine for me.
Aero1 said:Your misunderstanding of my statement that it works for 90%, shows a misapprehension on your part. The other 10% were not experiencing the problem due to habits.
All you have shown is your didn't read the original post and now are just ranting with anecdotes that you actually simply confirm what I have and the other testers have already said.fact of the matter is, there appears to be other underlying issues and bugs with the gps. the cache, may or may not be, one part of it. i personally don't have any issues with my cache running on the hot start setting.
after some thought, i realized you could be referring the the cell tower triangulation not working right. is that what you meant? if so, mine has not even been attempting to use the cell towers reguardless of settings. if im indoors and can't lock satellites, even with wireless location enabled, it will never do it. it hangs on the gps.
We are looking at that. Two most likely of a few possibilities:Why is it that you can have GPS locks, as indicated by the GPS Test app, but when you set your phone to Airplane mode, it loses all the sats? Very frustrating.
Note1: user boomerbubba was extremely helpful in thinking this through
Note2: Engadet finally posted a link to this workaround after three separate articles in which they completely botched testing of the Epics GPS and showed a total lack of knowledge of GPS systems. Thankfully their otherwise unfortunate readers of their poor "journalism" can at least now get a workaround as well.
I have three epics and have been testing GPS functionality for two weeks with quite a number of controlled tests.
As we know there is a problem with old "assistance" (the "a" in aGPS) ephemeris and almanac data in cache. this data can start expiring in a few hours and ephemeris will fully expire in about 8 hours.
The result is that sometimes users will experience the following symptoms in a GPS fail: the Epic will "see" sufficient satellites (4 to 11) but doesn't "use" them (expired ephemeris) or will see no satellites while under clear skies (expired almanac, rarer).
Although some user actions or program identified (eg reboot),and unidentified, can apparently flush the old data out of cache so that the network renews it with valid data, this isn't programmed by Samsung correctly and users intermittently are stuck with bad data in cache preventing lock. I have tested a workaround and it works
TESTED AND FUNCTIONING WORKAROUND:
Enter GPS debug/settings application by typing *#1472365#
click "Setup" tab
click "position mode"
Click "starting mode
Enable "Cold Start"
Back out.
Epic GPS will now call on data network for fresh valid ephemeris and almanac at every programing invocation of GPS and aGPS fixes will be very fast (usually less than 10 seconds).
There one downside. while cold start will be effectively warm start in aGPS mode (good). That is it will work very nicely in the presence of a 3G or 4g data connection. But absent data connection, ie in Standalone GPS mode, you will be always cold starting (starting with empty cache), meaning fixes will be 5 to 14 minutes if you are not on the network. If you are going to be off the network for a while you can simply set to warm start from same menu.
This doesnt work
