"Lazy" 4g responsiveness - Epic 4G Q&A, Help & Troubleshooting

Hey all.
I have had an issue for a long time on deodexed fc09 roms. I thought it was an issue with the specific rom I was using but think it is an issue with the rom that rom was built on. I am using the stock (for the first time) fc09 posted that is deodexed and has su and I think some kernel tweaks built in and I notice the same issue. My 4g sleeps and does not promptly wake upon an attempt at data transmission. Frequently I wait 5 seconds and often even need to refresh the page or action. Anyone have a clue as to why or whay I can change to improve it?

Am I the only one seeing this. I see it happen all the time when trying to predictively id searches or map locations or anythbing of thbe sort...not to mention in this very app. This has also occured with all modems (where I used to think the issue was) and on two phones now.

Mine does that. I hardly ever use 4g unless I'm downloading a large file. So it was never a big deal for me. I don't remember if it did it on eclair or froyo roms. Its been so long...

Hydra kernels problems

Just tried every kernel Hydra has to offer and every one put my phone into a bootloop. Had to revert back to stock.
Any tips to get these working?

I just think some phones can take it, and some cant...thats all i can help

I used the OC/UV ov, kernel #2 from Hydra. It was working ok but made my keyboard really laggy.
Sent from my rooted IncrediblÄ™
My keyboard is sometimes laggy but usually really fast. I've isolated the issue to the dictionary, I'm sure if auto suggest was off you wouldn't notice it.
Although, after using it for a day, the keyboard lag seems to have gone. Maybe it was repopulating or something.. no idea in this department.
Edit: these kernels are meant only for froyo

CM7 android system too high.

Okay so I noticed that even with the Tiamat kernal my battery life hasn't been great. I always see above 60% android system usage. I recently did the "GPS FIX" but I never upgraded my pri or NV. I need some help, I may skipped a step.

I would update all of your radios. Also, I think in settings under privacy, unclick back-up. Also, have you considered turning down how often your phone syncs?
It also could be a rogue app stealing resources... Let's start with my first suggestion, radios are in my Sig.

Okay this is weird, I turned off background data and now no system use. Is that saying it's a rogue app?

How many days was it high android use?
Sent from my PC36100 using XDA Premium App
Ever since I flashed the GPS fix but possibly after Google+ app. Either way its at 81% usage.
Sent from my PC36100 using XDA App
It's still high as hell ATM. 77% consumption. I don't understand. Wish I could get some help.
Sent from my PC36100 using XDA App
There is a fix for it you'll have to search for it I only saw it once
Sent from my PC36100 using XDA Premium App
Someone had a link for me in their sig but they changed it...and I searched to no avail. Sad cause I don't want to ditch cm7 for something so dumb. Just want my GPS to work without having my android system through the roof. Myn's Warm TwoPointTwo is on the other line. -.-
Sent from my PC36100 using XDA App
I had the same problem. Here's the fixes I did before I finally just ditched CM7
I updated my radios (and everything else).
All my syncs were on 4 hour intervals (except weather = 1 hour)
lowered screen brightness
uninstalled facebook, g+ and gVoice (my 3 highest used apps).
rebooted about 6 times
held it wrong
prayed to the gods of android
flashed Synergy RC2
So if you were considering doing those, don't. They aren't the problem.
Ironically, my GPS has never had a problem on any aosp rom (and I've tried darn near all of them), but like you, even with the kernels my stuff just wouldn't work right. I think it has something to do with our phones just not liking the kernel. Give toastch's "godmode" kernel a try or flash back to stock to see if that helps.
Ok so switch kernals or just switch to synergy?

4g will not work with app store

Is anyone having this issue too? If my 4g is on, i can surf the Web, but now it won't update apps or download them. It stuck on waiting for network, but when i switch to 3g, download starts right away...4g not working for downloading or updating apps.
Sent from my SPH-D710 using xda premium
It's been posted before in other portions of the thread. Nothing I can do besides the temp fix. Go to setting-manage apps- the find the play market and clear the cache then uninstall the update. You will have to do that every time you re enter the market under 4g
let me guess you are on a GB build possibly with a ICS modem? if so then you need to choose either one or the other. i was having the same problem recently and thats how i fixed it.

Guess again. I work for Sprint and brand new, never before touched phones are doing this out of the box.
But I have no idea why.

Yep ive gotten calls on this as well as confirming it on multiple stock phones with 4g.

It seems 4g falls asleep on the job sometimes and hits the snooze button on the alarm clock.

It goes back to the default settings if you flash roms correctly, just so you know.

Just recently started having this problem. Google Play was recently updated, so I dont think it was our phones or Sprint causing the problem.

Yes your correct there is no real fix until they update the market again. or if you flash a ROM with a new Ics market then it should work fine.

I had the same issue, but can confirm the upgrade fixes it.

Any app that does this?

So, here is the situation with my Samsung Galaxy S2. Every now and then, when the phone is left idle and I try to browse to use the Internet after a while, the speeds are unusable.
So, I run one of those network refresh apps every now and then (which basically puts the phone into airplane mode and back) and that always solves the problem.
My question is whether anyone knows an app that can do this automatically, say once every hour.
Now, this is an issue that I had with my phone ever since I installed ICS on it and none of the different ROMs had helped and neither did flashing different radios.
So, if anyone knows an app like this or has a similar problem with their phone, all help is much appreciated.
Should be a way to do this in either Llama, which is free, or Tasked, which is a paid app.

[Q] phone turns itself off

has anyone experienced their phone turning itself off, and the only way to turn it on is to pull the battery and restart it?
Never heard of that..at least on our note. I have experienced a weird rabdom reboot. Not sure of the relevance between the two but still falls under the weird category. Some say avast security causes these things...
Sent from my SPH-L900 using xda app-developers app
I dont have avast installed. I have had the phome for about 10 days and it has happened about 5 times. the only thing that I have noticed that is it happens when I look at my phone after I get out of my car which makes me think it might have something to do with bluetooth because I have uconnect in my car. I am running stock rooted ljc and have already tried a fresh install and it still happens.
Ive had the exact same problem on stock LJC when I leave my car having used the phone with Bluetooth. The led is usually flashing and the screen is stuck off until a batter pull.
I have not noticed any other lock ups like this otherwise when not using BT. Ive had the phone 2 months.

I have had this happen twice this week but chalked it up to being a custom kernel issue....it happened in the same exact location each time...while streaming pandora in the car....in a spot undergoing network vision upgrades. I will have to test it further

I know that there were some bluetooth fixes in lk8 I wonder if that was one of them. I cant run it cuz I need my wifi to work all the time. maybe it was adressed in ma5. does anyone running either of those builds have an issue like this?
I've ran lk8 on stock deodex and ma5 and haven't had any problems with wifi. But I only use it on my home network.

What kernel?
I was getting rogue restarts/shutdowns in calls on some of the Perseus kernels. Alpha29 IIRC.

I am on the stock kernel. only things different from stock out of the box are root, and I installed twrp from that goo app from the play store.
Update....
After running ma5 for the last 3 days I have not had this issue any more. If anyone is still having this issue I would recommend to flash ma5.
That's good news. Are you using just the updated modem firmware or an entire rom of MA5?

The entire rom.
Before the rom was available I flashed just the modem and still had the issue, but since ive been on the full rom it hasnt happened.
I guess I will update as well...I flashed the new modem and latest perseus kernel and have not had the shut off issue in the location it was previoisly occuring at.

I did the rooted no data oc and I was getting wakelocks from bluetooth share. I un paired and then repaired the phone with my car and the wakelocks went away. Just a heads up.
Hmmmmmm.... never had that happen to me. I am a power user too. I can drain the battery in 5 hours if I try hard.
