Phone App is sloooooowwwwwww on Sprint Hero...

My phone app has been slow since I got my Sprint Hero. But lately, it has gotten extremely slow. Almost unusable... it's slow to open, respond to input and ring when someone calls. Any ideas, tips or tricks on what the deal is?
I thought about trying to cut down my contact list to see if that helps, but I really hate the idea of not having all my contacts available on my phone.
Any other ideas to speed this thing up?
Thanks!

I'd try reflashing and if you dont want to go to that extreme I'd try to make sure to reboot the phone daily

Are you using a task manager? Also I find a reboot every 3 or 5 days is usually a good idea unless you clear out some of the memory hogging processes like Gmail storage and such. Generally I'll notice a bit of lag if I fall under 30mb of available memory.

I have considered reflashing, but was trying to see if there were any other solutions first. I've reflashed a few times and keep finding that after while, the phone app consistently slowed down.
I typically reboot about every 3-5 days... lately a little more. Rebooting has been much more effective that task killers.
I've read that some folks had problems with slow contacts, but is it also affecting their phone apps? How many contacts is too many for this thing? Is 130+ contacts too many for this phone to handle?

mine does EXACTLY this ... but only after I pull the phone off of charge.. the charge light stays on.. and bam.... its slow.... only fixes with a reboot

I have a lot of contacts
I have 1400+ contacts and my pone is not too slow.
Thanks

I like to use the "all people" widget its located under the live folders when adding stuff to your homescreens. Basically it just has a list form of your contacts.
Then when you select one it loads up the people app

I found out that some of the apps, were causing the problem, I started uninstalling apps, I guess most of the apps are made for 1.6 maybe because we are on 1.5 causes some kind of issue. that's just my theory...
In the mean time, you can try that.

I find the phone app very slow in response. It's very aggravating.

I noticed on the Fresh Rom, there is a note that the Location service may be what is causing the slow down in the phone app... I turned off location service yesterday and noticed an immediate response increase with the phone app. I'm not ready to call this a fix yet, but I am going to keep the location service off for a little while longer and see if it helps.
If anyone else is seeing the phone slowness, give this a try and let us know your results...

It does work. And for the sake of clarification, it's a 1.5-wide problem and affects all 1.5 ROMs.

Are you using the Facebook linking? I noticed when I had this feature on the phone and contacts apps. It's a cool feature but not worth the slow down.

Does that mean that Locale wouldn't work? I'd rather deal with the slower dialer if so.

Yes, I am using the Facebook linking. I could see that killing it too. I wish it would just import pictures and info over to my Google contacts. Any ideas on how to do that?
And yes, turning off the location feature will disable general location info from the phone. However, it can be re-enabled from settings...

It's a problem that has to do with apps using seperate threads to check your location, which builds up over time causing the location services to eat clock cycles like Rosi O'Donnel eats candy on Halloween. Disabling location services is a temporary fix, and Flipz thinks he's solved the problem in his 1.1 release by using Android's location services instead of HTC's

I have to agree with the abcdfv, fresh 1.1 has completely eliminated the annoying phone lag for me...amazing work. Now if someone could address the keyboard lag this phone is ready to rock...

Are you linked to a Facebook account and running fresh 1.1, and there is no lag in the people(contacts) app?

I have a linked Facebook account on my Fresh 1.1 ROM and while there is an almost negligible lag in the phone/contacts application still, it is drastically snappier and quick to response compared to the Stock ROM.

I have most of my contacts linked to their respective facebook and flickr pages. Coldsweat says it best as "an almost negligible lag"...still present but not an issue in the slightest (.5 seconds). I am experiencing the same change with the contacts as well.
Give it a shot and post your results...I was very impressed.

FYI, I turned off Facebook sync (synced Facebook pics with SyncMyPix), dropped my slot cycle index to 1 and installed the Fresh 1.1 ROM. Holy crap. This thing is a screaming fast new phone
For those who are rooted (and not aware), Fresh ROM has come a long way and is really, very impressive. It's very fast and some of the interface mods are very attractive.

Issues with 2.1...

Sorry in advance if these have already been pointed out and/or fixed.
I'm aware that this is a leaked beta but i'm having some strange issues.
Mainly being the market not downloading apps. I can browse the internet, browse the market, but nothing will download.
Anyone know of a way to fix this?
Also, i was quite disappointed with the fact that they did next to nothing to the absolutely terrible camera. The shutter speed appears to have improved *slightly* but pictures are still far too sharp and over saturated.
On the other hand, i do like the 720p filming
Another thing i noticed is that interacting with the live wallpapers is way off. When you press the 'Nexus' live wallpaper, the actual 'hit' is almost an inch out. Not a huge deal, just something that's annoying me.
On the plus side, the live wallpapers are incredibly smooth. A lot smoother than on my Nexus, god knows how dell managed that!
But my main hate, the one that annoys me to no end, is that you can now only have 6 icons in landscape. Wtf was the point in that dell? You took the best thing about this phone and made it worse!
Apart from alllll those things, i'm absolutely loving the 2.1 update (especially the dialler) but because of the above mentioned things i'm getting tempted to go back to 1.6. I need to download things dammit!

Another 2 issues that bothered me were the crap keyboard which is VERY slow and if you rush it you get mistypes, sometimes I have to press the same button twice as it did nothing the first time and I get a spelling mistake in every word, the keyboard is messed up.
Anyway to get the superior keyboard from the previous 1.6 with the lovely numpad?
Secondly, there are some problems with the wallpaper/homescreens. There is no way to add or remove them, seems I'm stuck with 6.
I tried to set a simple wallpaper on say screen one and it stretches right outside the screen and fills all 6 screens up, why??!!
I am using the same wallpapers before that are specially for the streak and are set at 800X480 and it stretches one pic across all screeens and it looks distorted, why?
Before I upgraded, I could go to screen one, put a wallpaper, it would fit fine and only in one screen, not fill the other ones too.
Can ANYONE think why this is or even a fix to this problem?
At the moment I have more problems with 2.1 than 1.6...

Glad to see I'm not the only one with these issues. I can't stand the new keyboard, driving me mad but I'll survive. I don't like the new layout of the icons and the fact you can no longer have multiple backgrounds is a shame. Also I've noticed certain widgets just won't sit in the centre of the home screens any more.
I'm hoping because this is a leak that Dell haven't added their personal touches yet and that this will come when they go official otherwise I'll be a sad panda!

Yeah, I guess we have to stick with what we have until it's officially released.
At least we have SOME improvements...

The portions you mention I have not had. It sounds like you have a few issues with your install.
With regards to we everthing else, 2.1 ain't perfect but its a tonne better than the 1.6

Of course by portions I mean problems....the swype keyboard although better its still far from perfect

Hi Meltus
If your Google E-Mail account is Googlemail change it to gmail by logging in through your computer and use the option to change it to a gmail address and that has fixed the Market problems for me and some others hope it works for you.
Marc

Any one else having issues that when talking on the phone with headphones in if you press the lock button it hangs up the call? Found something that drives me even more mad than the keyboard lol.

Not sure what I am doing wrong , but I can't seem to use any 3rd party keyboards ? They install OK , I can select them , but then when I go to use them , the Dell one pops up. (Any ideas ? )
The only issue I noticed , is that the Sleep/wake button stops working properly occasionally , instead of putting the device to sleep , it dims the screen , but the screen stays on ,
Not sure what is going on here , I think the phone may "think" its asleep , as the live wallpaper stops moving , but the screen is definately still awake.
The only way out is to reboot by taking the battery cover off !

Seems an isolated problem I don't have any problem downloading just that some games wont work - more importantly launcherpro looks very strange with tiny icons! Spread a across the screen with Hugh gaps.

i have had EVERY issue above! its beta so im not going to complain but i just hope its much better once the ota arrives

However, I do believe if you change to Gmail from Googlemaill, any apps you bought with your Googlemail account are NOT carried over.
Hence you have to purchase again, this is why I haven't made the switch yet, until that issue is resolved I will be staying as Googlemail.

Exactly the same problem here.
And to change keyboards, you select it and long press a text box (like in messages) then you pick the keyboard you want from there.
Anyway, i fixed my market problem by changing my e-mail from 'googlemail' to 'gmail' (thanks doggman) and then wiping the phone. Not sure which made it work, or whether it was a combination of both, but it's working good now

Issues I've noticed so far: (Maybe nitpicking but I'm comparing it to all my other Androids)
- Live Wallpaper could be smoother. It's pretty smooth but on such a large screen, little glitches are very noticeable.
- Though the keyboard is a lot more comfortable to use without the numpad throwing the right thumb off, the responsiveness is gone from the previous keyboard. But I'm sticking with it cause its alot better looking than 'Better Keyboard' or 'Smart Keyboard'
- No pinch-to-zoom on pictures in the gallery...very disappointing
- Pinch-to-zoom for maps is there, but responsiveness needs work. Almost as bad as Blackberry Torch's pinch-to-zoom. HAHAHA
- Photos seem more saturated than when it was running 1.6. Even affects photos when being used as 'Picture Frame' widget.
- Aside from the saturation of pictures though, the screen display overall is impressive. Quality has improved, sharpness has improved, the HD-feel is there for the home screens. I could even say that it is comparable to the iPhone 4, and better than the Galaxy S display. Theres room for improvements though... better font for icon titles, increase sharpness, less colour overflow.

Froyo Update Changes Thread - Pros and Cons

NOTE: THIS IS NOT A THREAD TO POST ISSUES WITH THE UPDATE PROCESS, ONLY ISSUES AFTER UPDATING THAT HAVE BEEN CAUSED/FIXED BY THE NEW VERSION.
In an effort to consolidate all the information into one thread, hopefully everyone can just post their own experience with the new Stock Froyo build here after having updated through Kies.
List issues you're experiencing, as well as issues that may have been fixed with this update from the previous version.
Hopefully this will cut back on thread spam and help people decide whether or not they want to try out the stock Froyo 2.2 update!
I'll start it off and say that so far I've heard that the Gallery is working great, but Avatar seems to be having DRM issues. GPS seems to be something where YMMV, some say it's great, some say it's worse.
What have you noticed?

So far all good things.
CONS: missing stock android keyboard, paid apps missing in Market until ROM is recognized.
I installed the GB KB and am good to go as far as that is concerned.

GPS in UVKA 7 still wayyy off for me, definitely a hardware issue.
I have not done any tweaks or change in settings, like a I said wayy off..

Pros (to me at least):
I noticed that the screen auto-rotation is now controllable via the notification/switch pulldown on the home screen.
I don't recall this from before, so please gently correct me if I'm wrong. While entering text, if you hold down on the entry window a blue pointer appears that you can use to place the cursor in the text easier.
Gmail improvements:
- You can reply/forward messages from the top of the email instead of having to scroll all the way to the bottom.
- You can scroll from from email to email by using arrows at the bottom of the window, instead of having to go back into inbox/outbox/etc and selecting the next email

CON: I can't get any data.
Any help?

With regards to the Calendar app, can anyone confirm whether or not you can now actually change the default calendar from My Calendar to Google? Or do you still have to change each new entry to Google when you go to add an entry into the Calendar? That was such a dumb move.... a step backwards from Android via Touch Wiz, heh.

Pros: higher Quadrant score than 2.1
Better UI
Mobile AP
Flash
Camera seems to be better in the dark now
Better battery life
Faster
Cons: No apps in the Market's Download section
Old market
Avatar is not accessible

You are able to set other calendars as the default calendar. I just created a new event and no longer does it default to the lame TouchWiz calendar.

The issue with the gallery lock was always random for me. So far I have had no issues moving in and out of the gallery.

Avatar doesnt launch because the mouny point for the external sd has changes. The drm issue im unsure how to remedy.
Lag is still the same.
Still cant set default home screen.
Changed calendar notifications to white background.
Skype anf yahoo apps should work now.
C2DM works for apps like Trillian (saves a lot of battery)
Will check if the exchange client still rapes battery tomorrow.
Oh, and wifi calling/sms for those of us in very low reception areas.
Data speeds seem incredible. Wifi reception inproved...
Improved txt selection copy and paste. Darker notification bar.

Major problem, the haptic feedback is really really really weak. This happened b4 when i flashed a leaked 2.2 rom and the official one does the same thing -.-, the vibration intensity is at max when ur in the settings and set it to max u get a strong vibration, however when u press any of the 4 bottom buttons and dialer u get really weak vibration, feels like its at the lowest setting. This really annoys me. Does neone know how to fix this or if a rom currently out has alrdy fixed it?

I have had horrible gallery issues, every time I opened it it would freeze. It's great now, but why the hell did they go back to old pics on the top? I want my recent pics on the top.
My gps did not work, but I turned it off, reset it w the gps restore app and now it locks in maps at 30 meters to start instead of 1400 meters. (so, much improved)
Avatar does not work for me, but I updated my co worker's phone, and hers works. wth
I can't look at my display settings, it forces close, I think because I had a bunch of flipfonts installed. I uninstalled them all and it still doesn't work. Any ideas?
ETA: Haptic feedback feels fine to me

I feel the phone is a bit lag too
I want to flash back to JFD and try it from zero again.
BTW I cant root with z4root, how can I root now?

KA6 was the version released through Samsung Kies

Flashed KA7 (screw KA6..). Took awhile to boot up but made it
Gallery seems to be okay, haven't deleted any pics yet. Phone seems as snappy as it did with KA5. Data speed seems the same as well. GPS actually performs better, if not the same as KA5. Just a minute or two to lock on and failry acurate within 30FT (on my way home I was able to lock onto 6-10 sats in a few seconds). Installed GB Keyboard, no issues there. Market udpated itself, apps show up and works just fine.
All in all, works just as good as KA5 did, with maybe some minor improvments.
PS. why is the haptic feedback such a huge issue? OMG MY BUTTONS DON'T VIBRATE WHEN TOUCHED!!

[Q] Delay in Opening Contacts in Note 3

Hello guys,
I'm new to the forum
I notice that there's a slight delay opening Contacts (3 seconds+) and Dialer (1 second+) in my Note 3.
However after opening it once, there's no delay opening it the second time,
unless I clear the Contacts Apps in the running apps and open it again.
I'm not sure if this happens from the fist time I unbox it; I didn't really pay attention at the time.
Maybe this happens after I turn off and uninstall updates on some of the bloatwares, but I'm not sure.
ROM is stock Samsung, everything is still stock. Just some updates to some of the stock apps.
I haven't installed any new apps yet. However, I do turn off and uninstall updates on some of the bloatware.
I've also changed the 3 settings (cant remember the names, animator or something) on the Developer Options to OFF.
And I've removed the S Voice from the Home Button too.
The Note 3 is the Exynos one. Stock Samsung.
There are about 800 contacts, all google contacts. They are also synced, together with gmail. These contacts are imported from BB 10 OS, and some have pictures from the BBM.
Does anyone else have this problem, and is there a fix for this? I've searched the forum, seems like some have this issue, but I can't find any real fix for this.
Thanks!

Sounds normal to me. It has to re-launch the app, and the app then has to re-scan all your contacts. 800 contacts is a lot to scan through, so 1-5 seconds is to be expected.

No lag here. Did you try a restart with cache wipe? Usually that solves similar problems.

I noticed the same lag. I actually noticed it on my previous phone (SGS 3). At that time, I used GoContacts/Dialer, which I thought might be the cause of that. After removing it, same lag with the stock dialer/contacts.
Besides, I was a flash-addict, and I noticed that on every ROM I tried.
And now, even if it's a bit quicker, I still notice it on my new Note 3 (@stock/rooted). But unlike on my SGS3, it's only the first time you open dialer/contacts that it appears (as long as the system doesn't kill the process).
I wonder if it might be a good idea to force keeping that process opened.

Solved. It turned out that my issue was caused by turning off Chat ON app.
I actually turned it off when I first got the phone, and now I tried to turn it back ON.
The lag is actually reduced to 1-1.5 seconds (much more acceptable than 3 seconds).
For others with the same issue, hope this helps

Glad to know you found resolution to your problem. Like another post suggested, when you are syncing your contacts to a device through a 3rd party application such as GMail, Exchange, Yahoo etc... The application runs an API in the background at application launch which pulls all your information onto the device. When you automatically sync, your device periodically sends a request to the server for contact details, task details, calendar details etc...
800 contacts and whatever other events you're syncing will definitely take time. If you press & hold your home button and your swiping your application out of memory and then reloading, like suggested, this is going to take a few seconds. By turning Chat On back on, this has limited the lag which is acceptable to you. This definitely is not a "problem" as I've initially stated but instead more of a communications lag between the device, your server and the API which is engaging in the communications.
Hope this helps!

I noticed that the lag goes off when I disable sync. Try doing that bro, do a two two finger swipe and disable sync from the notification panel and Try launching the contacts application again

Surely if that is the workaround. Its easier to wait 3 seconds! Lol

HELP - Notifications not coming through when screen is off

Hi everyone,
I've been having a very strange problem for a couple of days now. Whenever my phone's screen is off and the phone has been idle for some time, I don't receive notifications anymore. Facebook notifications don't work at all, no matter whether the phone is active or not, but I also don't get FB Messenger and WhatsApp notifications. Sometimes they come through as soon as I turn on the screen, and sometimes I only see them when I open the respective app. I didn't mess with app permissions, and I also have set each app to "important" in the notification settings. It also doesn't seem to matter whether I'm on WiFi or on mobile data.
Gmail, SMS and calls don't seem to be a problem, although I sometimes have a feeling that emails come through to my phone with a considerable delay, as compared to my Gmail inbox on my computer.
The strange thing is, when I had the phone all new, everything worked as it should and I received ALL notifications from EVERY app IMMEDIATELY when they came in. This issue with notifications no longer coming through started occurring a couple days ago after I had first flashed the Boeffla Kernel (though I'm not sure if it has anything to do with that.) So I went back to the stock kernel, but the problem was still there. Then I re-flashed my original Nandroid backup from when I had first flashed TWRP, in order to set the system back to "stock", wiped data and cache, re-installed every app (the critical ones, i.e. Facebook, Messenger and WhatsApp, via Play Store, and the non-critical ones via Titanium Backup), and the problem is still there. I've done this three times now, to no avail.
My phone is rooted and I have Xposed installed, I'm using SuperSU and a number of root apps such as 3c Toolbox, Le DPI Changer and Font Installer. 3c Toolbox is set to clear caches on every reboot. As for Xposed, I use only VibrateMode to change the notification slider from all/important/none to all/vibrate/none, and GravityBox to center the clock in the status bar and to set the volume buttons to skip tracks on long press. I also have Glimpse Notifications installed so that the screen lights up when a notification comes in.
The funny thing is, notifications not coming through is one of the reasons I switched to the OPT from the Huawei Mate 7, where this issue was due to power management settings by Huawei. Since I'm now back on the stock kernel and have also no power saving apps such as Greenify or Amplify enabled, I am really out of ideas as to why this happens. The next step is to flash a fully stock OOS 2.1.2 (my Nandroid backup is already rooted and with my Google account set up), wipe data and cache, and re-install every app again.
Does anyone here have any idea what the problem (and the solution to it) might be?
UPDATE: After I wrote the last sentence, I received two messages simultaneously, one from Messenger and one from WhatsApp. I was at home and on WiFi, and both coming in at the same time must mean that the phone receives push notifications in fixed intervals, since the sender of both messages was the same person and sent them consecutively, i.e. with at least a minute in-between. Now I am especially confused since a) they came through at all, even though the screen was off and the phone had been idle for at least 15 minutes, and b) they came through at the same time, which was definitely not the time when they had been sent.
The confusion is complete now ... any input is appreciated. Thanks in advance!

The problem persists. Today for half a day I received all notifications, after that once again only when I turned on the screen or opened the respective app. WiFi all the time, no settings changed in between.
This really annoys me to no end. I don't own an expensive smartphone so it doesn't work as it should. I never had any troubles like this with my old Sony Xperia V. Then again it ate through a full battery in half a day ...

Are you sure you are not using any applications like greenify / amplify or powernap which would hibernate your applications ?

Yes. As I said, I reflashed my original (rooted but otherwise unaltered) Nandroid backup and then reinstalled all apps, and am not using anything that could interfere with apps receiving notifications.
The order in which notifications come through automatically vs. only when I activate the display or open the respective app also doesn't seem to follow any regularity ... sometimes it works as it should, sometimes it doesn't.
As for Facebook notifications, I somehow have a feeling this is a specific FB-related problem. But as for Messenger, WhatsApp and now also Instagram as I've noticed, it's all the same issue as described in my original post. The only exception really seems to be Gmail, which always notifies me of new emails.
EDIT: All these apps have unaltered permissions, i.e. are allowed to keep the phone awake, and all apps are set to "important" for notifications, so this doesn't seem to be the issue either.
EDIT 2: I also installed push notification fixer to see what interval is set for the GCM services, and it's set to 5 minutes on WiFi and 6 minutes on mobile data. So that also can't be the issue.
Could the screen not lighting up when a notification comes in have something to do with deep sleep, possibly? But then why does it work for Gmail???

I could suggest you one more thing. Its a shot in the dark .
Could you check "Keep Wi-Fi on during sleep" in you advanced Wi-Fi settings ?
If the above is not a problem then out of ideas buddy. As a last option you could clean flash by wiping everything and just install whatsapp and other apps in which you are facing a notification delay. If it works then there could be some other application interfering , it it doesn't then i am not sure what it could be.

Yeah, that's pretty much my last resort. Currently, I'm trying to see if it makes a difference whether I keep FB Messenger and WhatsApp "open" in the recent apps menu.

try setting the refresh intervals in push notifications fixer to 1 minute

I could try that, you're right - I didn't yet because I didn't want to sacrifice battery life too much ... but I could give it a shot for at least one charging cycle and see what the effect is. Thanks!

i do remember reading some time ago that these intervals do not impact the battery life, but you could test for yourself just to be sure

So, currently most notifications are working again for me, for whatever reason. Facebook being the big exception, of course. Might have to do with keeping the apps opened in the multitasking overview. If that's what it takes, then fine ...

I've got a OPT for few day, i have same issue......anyone experience this problem? any solution? is it 2.1.2 problem?

Which app? Only Facebook, or other apps as well? For me it's working now, but I can't say why exactly. I use a number of tweaks on my phone (root, Xposed framework etc.) so I can't definitely say which of my apps cause issues and which fix them again.
As for Gmail, it appears that when there's already a notification for an email and a little later another one comes in, it won't play a sound or vibrate. That seems to be standard behaviour but I find it VERY annoying, even though I set Gmail to notify me on EACH incoming email.

despite suggesting a fix i seem to be experiencing the same problem as well. it happens on both wifi and mobile data so you cant blame any settings. my best guess would be its because of the latest update. gonna have to backup my data and revert back to the older firmware to solve this issue.

@vonotny have you found a solution? im experiencing the same problem after updating to 2.2.0

Not really, no. Mine are currently working again, after I re-flashed the stock system and set up everything again step-by-step. It's possible that some app or tweak or setting caused the issue, but I couldn't find out which one.

i suspected it could be because of restoring apps from titanium backup directly instead of downloading and installing them from the play store first, but even with that i still face the same problem. currently on oxyslim. come to think of it, could it be caused by the power tweaks? did you use them before when you faced the problem?

Same problem here on OOS3.0.1. Inbox and WhatsApp messages don't often come through until I turn on the screen. Completely stock. Didn't have the problem on CM13, I think. It's really annoying because I can miss a lot of important emails from work. Even put the apps I want in No Battery Optimization mode. No help really.

i have the same problem. I'm on OOS3.0.2 with Cyanoxy. Can anyone help?

Same problem here...
What the F?
This device is almost a year old and I still can't use it as PHONE. I am not asking for some fancy stuff, but fixing the gigantic bugs that are preventing me from even using this daily.

Fix for those willing to tweak the system: install the latest Boeffla kernel, it has an option to turn off doze.
