LOS

Hi guys, this is one of my first posts but I've been a long time reader coming from the Evo 4G forums. I'm rooter using Zedomax v3 and experienced multiple LOS as well.

Last night I tried limiting the clock speed to 1ghz and setting the min at 400mhz. Strangly I now get slightly better reception and never had a LOS yet. Will continue to test out this theory and see if it's clock speed related.

I came about testing this since I ran mine at 1.6 for a while and not only would I get more LOS occurances, I would also get phone freezes lol. I tether and stream music a lot so wanted to keep it slightly underclocked to keep the temps down. Hope this helps as a temporary band aid for the LOS bug
[Samsung Epic 4G Touch] Tyrantt23:
Thanks for sharing. Please keep us updated if you still don't get LOS after a day or two... :)

Also, what did you use to set your clock speed?

I think I've seen this option on JuiceDefender advanced settings, but not sure if it would work the same. Thanks! :)
[Samsung Epic 4G Touch] jtlcastro:
I'm using SetCPU to control my frequencies and so far it's been working great. Strangly my signal is pegged at 3/4 to full bars where as before right after rooting, it would be 1/4 to none.

It's been 12 hours continous use time of mixed wi-fi/4g/3g switching and still no LOS or strange roaming.

Just to compare, I did wait a while to root and paid attention to the signal since I was debating about dealing with LOS thats associated with root. I would always drop signal and/or go into roaming more than half the time where compared to my previous phone (HTC EVO4g rooted) I would at least have half strength.

Almost makes me believe that as the phone ramps up in speed, signal get crazy and when the phone drops around 200mhz or into deep sleep, it effects the talk/3g radios as well in terms of maybe low power?

I'm a regular user of 4G and it's never given me problems before/after root. As others have said, it's probably due to being a separate radio/chip? Suggestions and comment welcome
[Samsung Epic 4G Touch] ungovernable1977:
ok, got my phone 9/23, just rooted yesterday, flashed midnight 2.1, just got a LoS (just about 24 hrs. later), rebooted, back to normal. I have NEVER noticed a LoS before root, will it ever drop service, then pick it back up, say while youre asleep? Nevermind, I gotta read more into this... didnt have it, was hoping I somehow dodged the bullet... damn... oh well... the phone cant be PERFECT ;) mostly posted to report another incident...
[Samsung Epic 4G Touch] jtlcastro:
Quick update:

Been walking around the usual areas around here at work and noticing that I never go into roaming anymore. Signal strength seems more stable and data speeds for 3G are more consistant.

Using CPU spy, looks like the phone is always going into deep sleep often and capping the minimum speed at 400mhz actually improved my battery life as far as I can tell. I also did cap the max speed to 1ghz so maybe that may be a factor but phone no longer runs hot after taxing it a bit.

Still no LOS!

PS

This may be unrelated but the reason I capped my min Frequency to 400mhz is that coming from an Evo where people did everything to underclock/undervolt to save battery life, it actually made the system unstable when it needed to wake and/or restart randomly. I figured that the same concept may be at play here with the GS2 so testing and watching for any change. Before: I did have random restarts after rooting and having set min to 200mhz and max to 1.4-1.6ghz. Now: No restarts and going strong!
[Samsung Epic 4G Touch] blinkSS:
I as well am having problems and also testing this method and will post my findings. Since release, I've been experiencing upwards 5 LOS per day non-rooted, and rooted. I've been running these settings for 4 hours now without LOS.
[Samsung Epic 4G Touch] Tyrantt23:
I purchased SetCPU and downloaded CPUSpy... will also test out your configuration and give feedback. Hope it works, and thanks for sharing the info!! :)

Update:

My first time using SetCPU. I gave root access, then chose "Autodetect Speeds Recommended". I then have two slides (Max and Min). I set the Max to 1000, but the Min I can only chose 200, 500, 800... so I picked 500 for testing.

Am I doing something wrong? Is there a way to set Min: to 400 like you did? I'll leave it at 1000/500 for now. :)
[Samsung Epic 4G Touch] Smoked600:
Happened to me the first day I got my phone. Got worse when I rooted. If I had wifi on, i'd get LOS like every 45 minutes. when wifi off, about once every 4 hours. Running lostkernel now, had 1 LOS in 30 hours WITH wifi on. I can live with that.
[Samsung Epic 4G Touch] jtlcastro:
I flashed using the Zedomax V3 which includes 200mhz to 1.6. That may be why I have those settings. It's actually given me better battery life. Strange cause when I ran some benchmarks and let it ramp up to its usual 1.2, I got LOS :( It could be something related to clockspeeds and/or the throttling of it. :confused:

Still good and a mini band-aid though until the real cause is found. I only got 1 LOS today vs the 10-15 a day I used to get.
[Samsung Epic 4G Touch] AVakil:
Ever since I un-rooted and went completely back to stock, I haven't had a single LOS issue and I haven't had to reboot it since. My phone has now been up for 186 hours, straight.
[Samsung Epic 4G Touch] Tyrantt23:
Setting my CPU speed for 1000/500 didn't help for too long. I got the LOS where the signal remains, but I can't receive/send text messages unless I restart the phone. I will keep an eye to see how it does for the remainder of the day.

Is there an easy way to un-root? I'm too afraid to brick my phone or boot-looping, but I was wanting to give this a try...
[Samsung Epic 4G Touch] jtlcastro:
Yeah it doesnt get rid of the problem but it seems to help out a little. I tried the PRL update in the other thread when you need to input in your MSL and restart. So far so good, no LOS for an entire day so far.

I'm ramping up my max speed in SetCPU back to 1.4+ to see how that goes. If I get LOS then I'll drop it back to 1.2 and continue to monitor.
[Samsung Epic 4G Touch] kgbeezr1:
Have you been able to make a clearer determination as to whether the clock speed alterations are actually helping your signal strength? I exchanged mine, but am having the same low signal (usually around -101dBm at home), but if flashing this kernel and changing the clock speeds really helps, i'm on it. TIA
[Samsung Epic 4G Touch] jtlcastro:
Sorry, It's all voodoo fixes at this point. I've just been making those changes based on the pattern that when I do force high clock rates to gaming and benchmarking, I get LOS very often during or after the fact. I tried it again with low clock speeds both min/max at 400mhz and I've never had LOS. I set it to 200mhz and it happens often during sleep/wake.

controlling the speeds seem to help a little but again, I got one LOS yesterday. It's a whole lot better than the 15+ a day I used to get.

Just last night ~6pm I tried the PRL update which needs your MSL number to force update PRL and profile and still no LOS throughout the night. This morning, I decided to ramp up the speed over 1ghz to see if speeds were a factor to LOS. Still nothing as of right now, all is well! Even been randomly benchmarking at 1.6 or trying everythign to get it LOS and its rock solid. Hope this trend continues.

I'm rooted on Zedomax V3 using SetCPU to control freq and CPU Spy to monitor the different states and make sure the phone does indeed go into deep sleep

---------- Post added at 08:52 PM ---------- Previous post was at 08:48 PM ----------

update 5min later... I got LOS lol

still, for 12hrs straight it's a pretty good improvement! :(

It happened while my phone was in my pocket during my lunch. Oh well, time to drop the speed to 1.2 and see if that helps any
[Samsung Epic 4G Touch] sweets55:
I wasn't getting any LOS for a week then I rooted. The same day I started getting a few LOS for a few days. I went back to all stock/MSL reactivation and haven't had a LOS in 3 days. Yesterday I went out of town and to place with no reception but as soon as I came back into reception the phone worked. I didn't have to power cycle like before. I think something gets screwed up when the phone is activated and or maybe changing Kernels?

* Make sure you have the stock Kernel before you try this.

Some users said this worked for them. I just tried it this morning so time will tell.

***I think you need the stock Kernel or else you might get a bootloop

The MSL can be found by downloading "terminal emulator" and typing "getprop ril.MSL" It is case sensitive.

From there, go to the phone, and type ##72786# , at the SCRTN screen select yes, let the phone reboot, let the activation go through its thing NOT TOUCHING THE SCREEN unless it tells you to. Let it do a reboot again.

thanks - kingsway8605
[Samsung Epic 4G Touch] jtlcastro:
^

Yup, exactly as I did. It helped out tons but I was still able to get LOS after lunch today. The phone was just in my pocket and when I took it out, I noticed the LOS.

Still tons better than getting it 15+ times a day though
[Samsung Epic 4G Touch] blinkSS:
I just got my first LOS today about 15 minutes ago after editing the rates.. BUT, one LOS in about 36 hours as compared to previously upwards 5 LOS every 24 hours is a noticeable improvement.

Not sure if it's relative to changing the rates in setCPU or if it is just by coincidence, but I guess I will see within the next few days.
[Samsung Epic 4G Touch] bsloanindy:
Had my first LOS today... had just sent a text and made a phone call. Friend tried to call me back and said it rang and rang. Noticed I had the circle/slash symbol so I rebooted and then called sprint. Said they know about it and are working on a fix.
[Samsung Epic 4G Touch] soldier11b:
I have had two LOS since I bought my phone on Sunday. When it happened, I immediately came here to see if it was a known issue or not and once I saw it was, I let it be. They will push out a new update once they get the bugs worked out.
[Samsung Epic 4G Touch] bsloanindy:
@Soldier - you should call and report it to sprint via *2 on your phone. They need to know it's a widespread issue so hopefully they will get it fixed faster if more people report it.

Sprint doesn't want/need a black eye on their best new android phone. :) They were very nice on the phone and it took about 5-10 minutes.
[Samsung Epic 4G Touch] sweets55:
Also Sprint giving a $50 credit because of the LOS issue.
[Samsung Epic 4G Touch] Calkulin:
I think we need to differentiate the 2 very different problems with the same abbreviations that are affecting this phone, Loss of Signal(signal bars drop to none) & Loss of Service(radio is completely disabled, circle with line through it). LOSi is what Samsung/Sprint are trying to fix, LOSe is coming from the kernel source, let it be the files themselves or how the kernel is being built.

And just for reference, I personally have seen the LOSi issue minutes after buying this phone but only get LOSe with custom kernels, some more than others.
[Samsung Epic 4G Touch] buggerritt:
People are experiencing "LOSe" on custom and stock kernels. I happen to be one of the people who experience it whether or not I am on stock or custom. We're talking about the circle with the line through it and not getting service back until reboot. It seems to be much more frequent with every custom kernel. Good to see you got an Epic Touch. I look forward to your work on it.
[Samsung Epic 4G Touch] mattykinsx:
Exactly.

I've had both issues.

17 hours with the phone.

Have not rooted the phone yet.
[Samsung Epic 4G Touch] Calkulin:
From what I "heard", Sprint was focused on LOSi but if more people are experiencing LOSe on stock also, then both should be corrected in the MR
[Samsung Epic 4G Touch] kgbeezr1:
This is what I had been wondering about, but no differentiation has ever been made, even though it's clearly two separate issues. I'm on my 3rd (and final) E4G and they've all exhibited the same behavior - very low signal with occasional rapid increase/decrease, sometimes spiking to full bars (-64 dBm) before falling back down to -101 dBm which is where it usually stays. So, unless the signal strength meter isn't accurate, or there is some technicality in the way cell signals work that i'm not aware of, the phone is capable of great reception but for some reason is "tuned" to suck in weaker signal areas. I'd gladly give up a little battery life for the ability to use data at home. I've not had any issues with loss of service, even when my signal goes to 0 bars (-106 dBm) it doesn't disconnect completely.
[Samsung Epic 4G Touch] Product F(RED):
I noticed that the Epic Touch comes with EVRC-B codec enabled in EPST (##3282#). I know by default on the Evo and 3D that wasn't enabled. Maybe those of you experiencing a high number of LOS have it enabled but your area doesn't have it. I live in NYC and I rarely have had LOS (single digit number of times, maybe 4 or 5 tops).
[Samsung Epic 4G Touch] soldier11b:
Will do. Thanks for the advice.
[Samsung Epic 4G Touch] buggerritt:
I am not sure if that would cause it but, even once is too many times for this to happen. It's understandable for loss of the network in bad areas but, to have to reboot to get service back should never happen. Especially when you are in an area that gets full bars with 4G and are possibly connected to wifi while sitting next to a wireless N+ router (my home situation).
[Samsung Epic 4G Touch] ProStreetCamaro:
2 day old phone and already LOS 4 times. I may end up returning it before I am locked into this phone. It is a real shame. This phone absolutely destroys my evo 4g in every aspect other than the LOS issue which is a huge issue. :mad:
[Samsung Epic 4G Touch] soldier11b:
I know it's a big issue, especially for people that use their phone a lot for work, but if you like the phone, why give up on it? Especially since Sprint and Samsung know about the issue and are working it out. They will push out an update to fix the problem soon enough.
[Samsung Epic 4G Touch] sweets55:
I thought about returning mine on day 14 but just couldn't do it. I love this phone and when running stock I don't have to many issues. The damn thing is a beast but doesn't feel like one.
[Samsung Epic 4G Touch] sling:
If you want update from Samsung you have to push them.

One of The best ways to do that is twitter @GalaxySsupport

Let them know Sprint Iphone doesn't have LOS issue you will be making move to it if Fix doesn't come soon.

Yo, "that ****" will make the difference between you bricking your device and doing it right. Read the steps, because if you don't people won't be polite to you when you come back with problems.
[HTC EVO 3D] ShawnGotBANDZ:
I did read it bro, it says at the beginning "Step 1 - backup everything on your phone, nandroid backup"

that's what I'm not sure how to do yet, I haven't used it since about May and it looks different than the original Evo, so I'm completely lost!!! The menu has changed completely since I last used it...
[HTC EVO 3D] ShawnGotBANDZ:
I believe it, I just dk how to use it yet! I'm still new to this recovery
[HTC EVO 3D] DomSim:
What? It is just like any other recovery, go to "backup" from the first menu and backup. If you can't make it past that point in your own, maybe you shouldn't be attempting this.

And did you pm a mod to move this as it most certainly should not be in this section.
[HTC EVO 3D] ShawnGotBANDZ:
I haven't contacted anyone to move it yet cause I didn't know who to contact... I posted from the mobile app, it was on accident... but yeah on the evo it was different... I seen backup partition in the recovery, but I didn't see how to backup the rom specifically. like I said I haven't done this in MONTHS and I'm trying to remember/learn how to do what needs to be done, I'm sorry if I'm annoying anyone I just need to learn this
[HTC EVO 3D] DomSim:
seriously man, you need to do some more reading. you are going to end up bricking your phone. you are trying to rush into this without knowing what you are doing. read the stickies in the forum, then when you think you know whats going on, read some f'ing more.
[HTC EVO 3D] ShawnGotBANDZ:
I did, I read quite a few things over and over, I figured it out too, I actually had to do exactly what I thought I had to do lol I was just trying to DOUBLE CHECK with someone just in case that's all. it really is basically the same as old nandroid just says different stuff. Thanks anyway tho

Hey Guys, i really have tried everything i know and have not been successful. I have been running CM7 on my HTC aria for about as long as it has been out and i love the rom! :D

I recently just got My Xperia and over the last few days i have been slowly getting it to where i want it to be. so far i have rooted, have installed xRecovery, the CM7-zmod v003 rom, and i just flashed dooMKernel v04x/s for LOCKED bootloaders. I've tried the last three zip packages for set cpu. 2.22-2.23-2.24 and none of them succesfully installed. I have superuser permissions on AdBlock or AdFree whichever it is. But SetCPU is nowhere to be found. :(

Any Help would be greatly appreciated.:confused:

Also A HUGE thank you to everyone who puts countless hours into all these developments. It is so appreciated and we all owe you. So THANK YOU!:)
[XPERIA X10 Q&A, Help & Troubleshooting] macmanjpd:

I have fixed permissions and still nothing. The rooting worked as I have SU access. . . . .
[XPERIA X10 Q&A, Help & Troubleshooting] GreatBigDog:
SetCPU is a paid app in the Android Market or it's free for XDA users from the SetCpu application thread. Note the Zip files in the application thread are not for installing the application via XRecovery CWM recovery, you need to extract the .apk file from the zip, place it on your sd card and use a file manager to access and install it.

[XPERIA X10 Q&A, Help & Troubleshooting] GreatBigDog:
I'm not sure, could it be an issue with the Rom? Try a search in the Rom thread to see if you can find anything there.

Other than that, try installing the app directly from the market.
[XPERIA X10 Q&A, Help & Troubleshooting] emannxperia:
Update it via market.
[XPERIA X10 Q&A, Help & Troubleshooting] macmanjpd:
Thanks guys. I got it working.....after checking out several roms I've settled on the CM7 zmod 003. Using doomkernel like in the title. It is real smooth and pretty fast. I flashed the doom wifi zip fix but I am still having some intermittent wifi issues. Ill have to check the thread out to see what else I can find. Was thinking of editing build prop file to add some tweaks, any idea if its worth it with the cm7 build?? ... I already changed LCD density and I am really pleased with effect.
[XPERIA X10 Q&A, Help & Troubleshooting] GreatBigDog:
I doubt if there are that many tweeks included already in that ROM, it was one of the early ones after 2.3 came out. you'll probably find a few that will help improve it.

Just make sure to do a backup before making any changes.
