Hello XDA,
Ever since I updated my rooted Captivate to 2.3 last month, I have been having a few weird problems.
The first problem is that my phone has a weird refresh issue. Basically, sometimes, when switching apps, the homescreen (launcher pro) and other running apps don't retain their display, icons, status, or information. For example, sometimes when pressing the home key, the app minimizes and the home icons all have to reappear and refresh, taking up to 5 seconds. Another example is when using task switcher to switch to and from Reddit is Fun, the program must reload whatever page it was on instead of just jumping back to it.
This gets very frustrating when dealing with anything that needs to stay idle such as web browsers and certain games. It's as if 2.3 is closing the programs and then relaunching instead of retaining them in memory, but it's not consistent.
The other perhaps more frustrating problem is that the speaker does not work all the time. The phone switches to headphone mode and cuts out all the sound. Smacking the top of the phone sometimes makes it come back. Headphones always work, but this is problematic for me since I use my phone as an alarm. I've tried plugging in phones repeatedly, battery pulls, and made sure all volume is up, to no avail.
Thank you,
Brian

Brian, I'm actually in the same boat as you.
To fix the speaker issue (in order to get my alarms back) I've had to remove the back cover and apply a good press down on the simcard, and speaker itself. this has brought back the audio for me.
I've had the phone for 2 years though, so not sure if this is the issue/fix you need. But worth a try.
I've only had my watch 16 hours or so (7 of which I was asleep), and I like it, and plan to develop apps for it..... but I have the following issues:
Updated (9 Jul)
Take a note voice command just sends me an email, instead of using something like Google Keep
The screen dims for a second before screen turns off (or goes to clock) - if I do OK Google during this time it ignores it
Set a Timer voice command does not work - options set an alarm menu
No music controls when I use default music player, or RocketPlayer Solved my Wear Music Controller
When doing a voice search, it often says Disconnected. 6 times so far, one time I had to restart watch before it could reconnect.
Dictating a longish email will eventually fail, even though it recognized loads of the words.
Step count often not updated on homescreen widget, despite it showing a higher number in the actual watch app
Dismissing a google now card (weather for example), you can't get it back if you did it by mistake
Navigation started from watch sits on Calulating route... if music playing on phone with screen locked.
Screen stays on while charging (reported by dunjamon) Solved by Slumber
I have it paired with HTC One S with Liberty S4 MAX custom ROM.
Anyone else have these issues (what device do you have it paired with)? Or know how to fix/work around them?
I have 4 and 7 8 D:
Number 1 confused me for a while. I searched everything on my phone before I realised that it had just emailed me. With number 7, I've turned off the step count...yet it still tells me my total of 0.
Also, is with the screen always on settings set to no, when you put it on charge the screen stays on. It's a nightmare at night, I have to turn it off and then boot it back up in the morning. There needs to be some kind of sleep mode or setting to allow the screen to be off while charging.
I've had 3 and 5
5 is a bit annoying. I'm hoping a restart means it won't recur as I go thru the day...

I didn't know about these developer options: Tapping build version several times works, same as a phone. The "Stay awake when charging" option is disabled by default however. I've only recently enabled the "always keep screen on" mode, so will be interesting to see what happens when charging tonight...
Regarding 1) It has started working! I installed Evernote for Android Wear from play store, also Baby Time and Draw Watch. I also resycn'ed all apps using the option in the Android Wear companion app.
Next time I did "take a note", it asked if I wanted to complete Action using Keep or Evernote, so I chose Keep. I also can see Keep in the list of apps on watch (before it wasn't there). The note was stored in Keep. Still works after uninstalling Evernote.
Regarding 4) I installed Music (Remix) Trial from play store, and Pause, Prev, Next actions are now on my watch. Unfortunately, the buttons do nothing. Not sure if this is an issue with my particular phone or what... Anyone else tried this app?

I've already disabled the stay awake while charging option. Unless it needs to be activated and then the watch itself to be set to not be always on. Will have another play tonight.
I've also noticed Keep show up in the apps now after another update. Will test out another note and see where it goes.
Got none of these problems with my watch. Fix for 8: If eg you swiped away the weather just say "ok google, what's the weather". after it told you the card should be back. this works for me, also with others like world clock, steps etc.
Just tried the screen off while charging and it doesn't work. The only way I can get the screen to turn off is to put it on charge and then on my phone set the screen to go off.
I actually have none of these issues...

I hope it isn't the case where everything will only work flawlessly with the latest Nexus devices. Have Google tested Wear with anything older?
I suppose it would make good business sense to encourage peeps to fork out for a Nexus 5 after spending money on a Wear watch...
Another issue I'm seeing is starting a Navigation from the watch won't work if I have music playing on my phone (phone lockscreen has music player UI). It just sits there on Calculating route... I'll add this to my list (and others from other peeps)

Number 4, music control, works well with Pandora. I like that I can start Pandora by voice, but there's no way to shut it down the same way.
Number 8, the disappearing cards was giving me hell on stocks. To resolve, I opened a browser on my workstation, Googled "quote xom" or whatever stock, and then the stocks card reappeared. I suspect a simple "Ok, Google...quote XOM" might do the same thing.
None of these issues. Nexus 5 Stock 4.4.4. You are also using a custom ROM so.....

No 3. Timer kicks straight into Alarm picker. Timer does work when you get to Google screen, swipe up and manually select it. But that's not a solution. I'm on stock 4.3.
Having the control issue with google play music and youtube when connected to chromecast he buttons wouldn't work and with youtube wven tho there was nothing playing the buttons were still on the watch and couldn't be dismissed
also having the connection issues if i take the watch out of the reach of the phone the app won't reconnect unless i go into the app myself to do it even then the watch says it's not connected when using ok google
EDIT: Happened again this time can't get the Ok Google working at all
Anybody else having issues where raising your arm to activate "Ok Google"isn't working consistently? We've got 2 watches in the house, and I've worn both. Same issue. Seems like if you don't use it for awhile, the arm motion won't wake the watch back up.
Sent from my HTC One_M8 using Tapatalk
I'm having some of the same issues. I've had a few smart watches to compare.
-My Gear 2 worked way better as far as waking up when raising my arm. The LG G is difficult to wake by raising my arm.
-Bluetooth doesn't connect automatically when I get back in range of my phone. The other smart watches have done this that I have owned so not sure why this issue exists.
-There's no way to set the screen timeout. This thing times out very quick. Personally, I have no problem charging my batt every night so I would like to take advantage of the 30 or so % that is left on the watch each night by increasing the screen time out, vibration duration etc.
-I have a difficult time getting cards back after deleting even if I search for the stock, weather, etc. again.
-No way to reply to text messages.
I'll add more as they hit me.
So, it's been bothering me for a while but my now 2-year-and-2-month old Samsung Galaxy S3 always just runs incredibly slowly. Not only that, but I tend to burn through the battery easily within 6 hours. For the past year and a half, or so, I've had to resort to carrying around two spare batteries with me as it has a tendency to run out of charge in the middle of the day, let alone if I'm out at a music festival or something. I'm not a particulaly heavy user, as in I rarely play video games on my phone, nor do I really watch videos or ever use bluetooth. Occasionally I do use GPS or WiFi, but I try to keep them turned off when I'm not using them. I tend to use my phone for music when I'm in the car, or texting / whatsapp / occasional snapchatting, or checking Pulse News or my internet banking. I don't have a particularly huge amount of apps installed, I don't think. And I regularly hold the Home button, & press the close-all-apps button to make sure that they're not running in the background.
Yet, my phone is so laggy. It's like there's a constant 3 or 5, or even sometimes 10, second delay for whatever action you've initiated to actually occur. You'll press Messages, and it'll take about 4 seconds for my text messages to show up. You'll press Home, and it takes about 3 seconds for it to close. Facebook just took about 8 seconds to load. It doesn't sound alot, but it can be quite infuriating when you're trying to get things done in a hurry. It's even worse when apps are running in the background!
So, I got to check my running processes and there's just loads of things running that both don't appear to be running when I hold the Home button but also shouldn't be running because I haven't used them in forever. It appears my phone has approximately 850MB of RAM, yet my phone tends to ALWAYS run at around 725MB used (currently it's at 751MB, as can be seen in the screenshot attached). But when I do go through the list of things running, the right hand side it tells you how much RAM is supposedly being used. Yet if I total up all of the RAM being used by all of the apps that are apparently running, it only comes to about 300MB. So where the heck is this other 450MB of RAM being used?! THIS is what is slowing down my phone, I think.
Not only that, but there are things in this list that are running that shouldn't be running, & I don't understand why they are. Facebook, sure I can understand, in case you get a notification or something. But TuneIn Radio... I'm not listening to the radio at the moment, nor have I used the app in weeks (and my phone has been restarted numerous times since then), why is it running? S Voice, too? Video Hub? Google Play Music, I've never even used it. And then there's loads of things I haven't got a clue what they are, like Exchange Services, ELM Agent, SmartcardService, etc. Now I understand it's like a computer, where there are a number of background processes that have to run to make the OS work, but why are all these other apps running that I'm not using?!
-------------------------
Furthermore, I've started trying to use Google Now because I would like to get a Moto 360 (but I'll ask questions about that in a seperate thread). So, it seemed to work fine a few weeks ago. It gave me stocks, news updates, ETA to work or home, started remembering where I was parking. But now a few days ago I go back to it, after not using it for a little while, & it's all reset; Asking me to set it up again. So I did, & it mostly works but I can only ever seem to get the first "page" of cards up. When I click "More" at the bottom I just get an endless spinning circle & then the message "No Internet Connection - Content was last updated X minutes ago" appears as the top card, when infact I know I do have an internet connection. Exiting the app, closing it down, & then re-opening does not fix the issue either. I'm at a complete loss as to what to do.
Furthermore, it always asks me to "Improve my location: For more accurate location, let google search for Wi-Fi connections, even when Wi-Fi is off." I don't understand how this works, and what it's trying to do? If I turn it on, is that not going to be effectively the same as leaving my WiFi turned on at all times? Well, except without the benefits of being connected via WiFi. It's just going to drain my battery more, as leaving WiFi on usually does.
-------------------------
So tldr:
- Why is my RAM mysteriously using 450MB that I can't vouch for? Where is it going? How I stop it?
- Why is Google Now not letting my manually update the cards?
You are missing huge amounts of very basic information, search and read for what is safe to disable on stock rom, some things are vital others are optional.
If you leave everything running as default then 6hrs battery life is about right.

I have a Verizon Samsung Note 2. It is NOT rooted, running stock ROM 4.4.2.
I have been having issues with bluetooth devices having audio cutting in & out issues. Here is the odd thing, it doesn't loose connection & it doesn't happen with everything I connect it to via bluetooth.
I can connect with both my vehicles & no issues.
I have 2 LG headsets & a JUMBLR bluetooth, that the audio with cut in & out after 3-5 minutes of playing. I can restart the device & it will work, but with the same result.
I have a Jabrees bluetooth device that will stream audio just fine, no issues.
I am at a loss as to how to correct this & am looking for some input.
Thx in advanced!!

I'm not sure if this will help or not, but you might try an app that basically keeps your phone's cpu from dropping down into the lower mhz range when you're not actively using the phone. (I'm guessing you probably lock the screen when playing music).
An app like Wake Lock Power Manager might work, found here: https://play.google.com/store/apps/details?id=eu.thedarken.wl.
I actually stopped using Wake Lock Power Manager and switched to an app called Blank Screen ( here : https://play.google.com/store/apps/details?id=com.mirwanda.blankscreen) . I'm not totally sure... but I think that when you only have the screen go blank with this app... that it allows the cpu to keep performing as if the phone still has the screen on.... which may keep the cpu from dropping down into power saving range. I've never run any tests to confirm this theory, so I could be totally wrong.... However it works though, it seems to help prevent the stuttering problem I was having.
I also try to remember to long press my home button to close all running apps, then go to task manager to clear memory before starting up my music. Using the Blank Screen app and taking these extra steps seems to have solved the stuttering for me. It might not work for you, but won't hurt anything to try.
I will try it.
What other don't understand is why doesn't it do it when I'm streaming through my car & the screen is off?

Yeah... I'm not sure what would cause that either. A quick Google search shows that a lot of other people report having Bluetooth problems with KitKat 4.4.2, so you're not alone with the problems. Maybe the quality of the antennas on the LG headsets & JUMBLR are not as good as the antennas in the car and other device. I also wonder if something is trying to sync or run in the background on the headsets... and maybe it doesn't do this with the car??
You could try turning off auto sync on the phone to see if this might help. You could also try to Disable (Turn Off) different apps through the "Manage Apps" feature under phone's settings to see if this might help.
Another easy thing to try would be to clear the phone's "Cached Data" to see if this might help-- (I read somewhere on the Internet where someone said this helped them). You can do this by going into phone settings / storage / then touch on Cached Data and clear it.
Also... here's a post where someone says that they had duplicate Google Contacts that were syncing issues/ that ultimately was causing their Bluetooth problems ( http://forum.xda-developers.com/showthread.php?t=2646592&page=2 ). They say that by going into Google Contacts and deleting the duplicates, that it fixed the syncing problem and the Bluetooth issues. (You could do this by going to Google Contacts at https://contacts.google.com, the go to "Find Duplicates," and either merge or delete any duplicate contacts that it shows).
You could also try rebooting the phone into Safe Mode to see if the Bluetooth works better. If so, this may indicate that an app you installed could be causing the Bluetooth problems. To get into Safe Mode, Power off the phone, and then Press the Power button again to turn it back on... but also press the Volume Down button at the boot up splash screen and continue to hold volume down until the phone boots up completely. This should boot it into Safe Mode and you'll see Safe Mode in the bottom left of the screen. If Bluetooth works better in Safe Mode, then you can just reboot the phone and it will go back into Normal mode...then try disabling or uninstalling different apps and see if the Bluetooth works better.
I decided to save a good amount of my battery by limiting the usage of wifi network connection only to the time I use my phone
so I downloaded and installed 3rd party app which allows me to control when it switches on/off and here's what I did.
connect to wifi when the screen is on
disconnect to wifi when the screen is off
it is this simple. and I expected it to function just as It should be
everything worked just fine.. or not.
I had to wait for like 5 seconds before it started to finish the wifi connection after I screened it on, which is not a good thing.
the purpose of setting all this is because I want to keep my wifi off when I dont actually use it like when surfing the web or watch streaming videos but at the same time I wanna sometimes turn the screen on and right back off only to momentarily turn the wifi on to get my notifications like emails or whatsapp messages which I will miss otherwise
so how can this be done? I want to press power button twice like double clicking mouse to get brief wifi connection so it performs the synchronization each time I do the job. if that turns the wifi off too fast so doesnt provide enough time for the wifi connection. then I can simply set the time wifi disconnected to 10 secs after I turn it off
so the main problem is how to make it turned on when the screen is on. almost simultaneously so I dont need to keep the screen on for a couple of seconds.
I eagerly need this function because I want to put my phone in the pocket and time to time double tap on the power button which Is very convenient to not miss all the notifications.
it doesnt matter when I seriously use the phone as I said ealrier, waiting for a few seconds doesn't hurt in that case.
thank you
p.s) I tested this to several phones and only 1 which I have doesnt let it. any solution?
apps, settings, rooting, custom roms, tasker, anything will do, except for buy new phone
