[Galaxy Tab 3 Themes and Apps] gagan313:
Hi guys. I have been on android since 2011 and ever since I have been modding my phones and devices. One thing I found out is that when you pack your device full of goodies and games and apps, your device can start to get laggy and the battery drains faster.

As for the Galaxy tab 3 I saw that it gets quite laggy when some apps are installed....

Here's what I do to manage and Maintain my tab:

Battery life:

1.) The number 1 thing I do when I unbox and setup my device is install Battery Doctor.

-This app I found charges your device in a certain way to prolong battery survival and it does it in 3 steps.

-This app also has modes that you can turn on that you can customise to a setting of your desire.... it comes with 3 as standard. Extreme mode and super saving mode helps a lot when your not using it for a while.

- Lastly it has optional widgets that you can put on home screen that optimises the battery, cleans apps/cache.

2.) Another one that you may find as useful is MobileCare. This app has a battery saving mode, App manager and Task killer if your are looking at JUST battery. This app offers a much simpler way to reduce battery drainage from the click of a switch power saver mode is enabled.

Performance Enhancing Apps

So to have optimum performance without rooting your device or overclocking here is what I use:

1.) MobileCare - As well as battery saving there a few other tweaks it has that I didn't mention above....

-Game Speeder- this basically give you a choice of the app you wish to run and it will basically optimise the app/game for you so it runs as smooth as possible.

- It also has a built in Antivirus/Anti-theft feature which also speeds and improves performance if there are viruses or ads slowing you down.

- Task killer- this app basically kills all apps and processes so the ram is nice and fresh.....1gb RAM can get packed sometimes.

2.) Memory Booster- This apps really helps as well.

-It features a Quick boost mode when you just want free space and instant performance.

-It also shows proof of it working in the form of a monitor and a diagram showing ram before and after.

-This app also features its own task killer and a boost log.

-This app is really useful because it comes with some really nice small compact widgets that you can do the quick boost function and task killer from a simple tap on the home screen instead of actually opening the APP itself.

Please feel free to add on to this list....I wrote these because they were the most efficient in terms of being able to use them seemlessly.

This thread is ideal for those who havn't got root access and want to maintain their tab 3's.

I will upload links Shortly.

edit-----I know the Task Killer mentioned dosnt kill ALL the apps and processes. However the point of that app is to close all of apps and processes that wouldnt harm your system if they were closed, so you have you normal open apps that need to be closed and then some background apps and clears cache etc.
[Galaxy Tab 3 Themes and Apps] dtaylorr:
Not bad, but rooting is so easy and you get much more control.
[Galaxy Tab 3 Themes and Apps] gagan313:
Yup.. But even after rooting... BAttery doctor really improves battery!
[Galaxy Tab 3 Themes and Apps] trazfer:
I use juice defender ultimate and du battery saver pro. Best battery saving app. The best contributor is lux auto brightness( paid version). Brightness is very crucial for saving battery. Ex. At night our tabs tend to be more brighter. You can even set the brightness for any light level your in.
[Galaxy Tab 3 Themes and Apps] gagan313:
LOL I totally forgot about that one. I liked that app for its quick features... most of it was paid though..
[Galaxy Tab 3 Themes and Apps] BretonGirl:
Task killers are useless and in fact do more harm than good. Android is quite good at managing its own memory and doesn't need the help. Task killers tend to stay in memory which defeats the purpose, and 99.9% of the time the tasks they kill automatically restart anyway. They are not at all necessary and should be avoided.
[Galaxy Tab 3 Themes and Apps] ironman38102:
I do and also dont agree having task killer why? They dont kill every single app u wanted and thus free only 5MBs of ram. Most apps like Advance Task Killer do the job well but the app itself takes the memory which makes it a disadvantage having a third party app task killer but then they do free up memory very well. Until now I havent found an app which has very less ram consumption and frees up memory very well.
[Galaxy Tab 3 Themes and Apps] dtaylorr:
Simple, already built in

They already have a task killer/ram manager already built in.

Simply holding down the middle button brings up all your resent apps with the option to kill all on the right, and on the left an extension which shows among others a RAM Manager.
[Galaxy Tab 3 Themes and Apps] ironman38102:
I do know that.

so laggy

Hi guys, I just got the tab 3 8.0, and I like most part of it but the performance is seriously bad..I have restored ask my apps from Google server and while running apps and switching between them, I can't take all the lags it has. I just got it today so I can return it if I want but I'm wondering if rooting this device actually gains much performance improvements. I used to have a galaxy s2x, which has a similar if not worse spec than this tablet, and I don't know if I was running rooted version of touchwiz or not but the performance was pretty good. This tablet is much worse. A simple reboot fixes the lag but after a few hours, as I use it, I notice the stutters while using it. I just had a serious lag in Google plus app, it was stuttering so bad, but it came back to smooth after 5 seconds.

So installing the custom Rom available for tab 3 8.0 improve the performance significantly? I know there are not many ROMs for tab 3 8.0, so any user of this device just rooted the tab and tweak it themselves to gain performance improvements? Not just little bit, but a lot.

Thanks!
[Galaxy Tab 3 Themes and Apps] BretonGirl:
Mine is not laggy in the slightest, in fact it's quite zippy. Instead of blaming the device, look at your apps. It's possible one of them is the culprit. If a reboot helps, it sounds like you have too much stuff loaded in memory. How much free space do you have?
[Galaxy Tab 3 Themes and Apps] gagan313:
I know what you guys mean...... I know they dont kill all the apps....BUT it still makes a difference.....even if it kills off 200mb of cache and apps.... It makes a dramatic improvement to performance if you are running on a a stock rom! Not all of the task killers work as effectively as eachother I admit :p but some apps are really good for a quick time boost:p
[Galaxy Tab 3 Themes and Apps] thref23:
I'll chime in. I always read that task killers are useless, because Android inherently does a good job of managing memory or what not. I personally dislike Android's autokiller; the more RAM you have the more it will work non-obtrusively, but it generally has a tendency to kill apps I don't want killed, when they don't need to be killed, and it does nothing at times to kill apps I don't want running.

What I do is I use Minfree Manager (I run it manually on boot, I'm sure there's a file somewhere you can edit which makes the app unnecessary)) to tweak the auto-killer, such that it doesn't kill apps except when absolutely necessary. My previous phablet, I used ZDBox to kill non-whitelisted apps every time I turned the screen on (and I manually killed whitelisted apps when applicable). This worked well and I only have good things to say about ZDBox, the older version was very lightweight and easy to use. Unfortunately ZDBox's task killer is incompatible with the Galaxy Tab 3 (at least my T211).

Thus far with the T211 I have been using Super Manager to kill non-whitelisted apps (like Google Play Services, etc) on standby. I am not sure whether it kills them, it only claims to "clean memory." Yes, they all start back up and memory usage increases quickly once again relative to the blacklisted apps, but this still prevents these apps from running non-stop and accumulating RAM usage, and even if that is meaningless, it at least serves a purpose by flashing a note in my status bar every time I toggle my screen on and off, regarding how much free RAM I have and how many apps are running. Yes the service runs in memory constantly, but that can't possibly be causing a problem because everything is fairly speedy.
[Galaxy Tab 3 Themes and Apps] gagan313:
I know what that guy means though..... I was running stock rom with stock kernal on my 7.0 and it was fine until I started downloading apps for it....It got to a point where no matter how much I overclock to performance it would still lagg even when i closed all my apps.

However I downloaded a custom rom with all these tweaks and now im running those same apps I had before running as sweat as a nut without even overclocking.:silly:
[Galaxy Tab 3 Themes and Apps] tempdroid:
Hi mate, you are using my ROM, right?

I just quote, so other users get to know RocketTab as well... :p

And I'm still working on further improvements...
[Galaxy Tab 3 Themes and Apps] samalama76:
My Galaxy Tab 3 8.0 runs great from stock, but since rooting and using arshull's kernel (latest release) with the addition of trickster mod app, I am getting super snappy performance! With the ability to tweak cpu and gpu settings and build.prop tweaks I couldn't be happier. Battery life is good and I am a heavy user and lag is nonexistent in games, even some of the heavy duty ones.

BtW, a big thanks to arshull for his development with the GTab 3 8.0, and this forum and all its contributors! :good:
[Galaxy Tab 3 Themes and Apps] Buddhacrous:
well keep in mind the 8.0 has an extra .50 of RAM. So that does effect the performance. I'm having the same issue. I have the S3 with 1.5 of RAM and never have any issues with lagging or apps running out of memory. Im wondering the same thing as the OP if a root would benefit this tablet in the way of performance.

If anyone has a 10.1 that they have rooted could you post any results or performance improvements that you saw from it?
[Galaxy Tab 3 Themes and Apps] Meteore:
Same here really curious to know the results:cool:
[Galaxy Tab 3 Themes and Apps] RazerKnight17:
Please give us the link of the specific app "from google play" and also please don't give ad.fly or something that makes us go to some advertisement first before going to the application place, Thanks.
[Galaxy Tab 3 Themes and Apps] Albhorockz:
Thanks for the guides.

Thanks . I will really help beginner to have keep an eye on their phone
[Galaxy Tab 3 Themes and Apps] bensonhsu2008:
I don't like the idea of freeing ram because android is meant for multitasking... lol

But here's my advice if you want a smooth device and hate multitasking.

beginner: Read and learn and don't do anything...

advance: Use scripts and install roms and kernels

pro: Compile kernel and tweak oom values

:p
[Galaxy Tab 3 Themes and Apps] _alex74_:
Flash my theme.....:D

it is near on the finish line.... with all inverted, my battery lasts 3 times more than before.....

Black = pixel switched off - small battery usage

White = pixel switched on - maximum battery usage

if u look with any battery program you'll notice display is main culprit of battery usage....

Then if u want u can use the great OP guide and gain even more......

Hi guys, my galaxy 3 8.0 is very laggy and want to flash some smooth ROM to improve performance, but do not know which one.. Which ROM is best for this tab?
[HD2 Android Q&A, Help & Troubleshooting and Genera] alexfmos:
Hello everyone. Firstly i'm sorry for my english.

I have last Energy ROM from this thread on CLK. Earlier sometimes i could not start mobile internet. (Letters E or H not show in statusbar), but i fix this restart HD2. Now it's not help. Airplane not help too. Something blocks this. In fact, now i can't use mobile internet in any way. I'm not changing operator and SIM-card. And i don't want change this ROM. Can anyone help me?
[HD2 Android Q&A, Help & Troubleshooting and Genera] Marvlesz:
Is it just data or Wifi doesn't work too?
[HD2 Android Q&A, Help & Troubleshooting and Genera] alexfmos:
Only mobile internet (I do not see the icon Edge or Hspda or 3G in statusbar)

Wi-fi, bluetooth, phone calls work fine.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Marvlesz:
Go and check the APN, make sure it is set up AND selected. If all is fine, turn on airplane mode, reboot device, turn off airplane mode then try connecting. Tell me what happens.
[HD2 Android Q&A, Help & Troubleshooting and Genera] alexfmos:
APN is fine and selected.

I do this before, but i do it right now again. Nothing has changed. Data not connected. One strange thing. After reboot airplane mode turns off automatically, i tried this twice. I do not know, may be is important.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Marvlesz:
This might sound silly, but are you sure your data-package hasn't expired? I mean, try the sim card in another device, or call customer service. (If you're not sure).
[HD2 Android Q&A, Help & Troubleshooting and Genera] alexfmos:
I was absolutely sure of that, until you said it :) So i picked up my wife's phone (HTC Legeng) and switch our SIM. My SIM in Legend work fine. SIM wife in HTC HD2 also does not work (i mean data):(
[HD2 Android Q&A, Help & Troubleshooting and Genera] Marvlesz:
That is weird.. Try reflashing your current Kernel, and make sure you select "PPP" connection if possible.
[HD2 Android Q&A, Help & Troubleshooting and Genera] alexfmos:
If I understand you correctly, I have to install ZIP v. 0.2.3 from this thread in CWM. I did it. Nothing has changed. I'm not understand about PPP. Wath exactly i need to do?

I suppose my options are ended :crying:
[HD2 Android Q&A, Help & Troubleshooting and Genera] Marvlesz:
Yes, you understood correctly. But with that, I don't know what else might be the cause.

Let's go from the beginning: You said your data used to work fine, but one day it stopped. What happened in that day? Did you change something? Did you remove/change the sim? Did you install a certain app? Did you mess with a setting?

I wouldn't say your options have finished just yet.
[HD2 Android Q&A, Help & Troubleshooting and Genera] alexfmos:
Firstly i use mobile data very rarely (May be one times in a week) because most of the time i'm on work or home with Wi-Fi. But sometimes i really need it.

Data works fine, but not always. Sometimes this thing happened before, i mean data not started, and i fix this restart HD2 (it's sucks, but i could live with that). Then of course some apps was updated. I'm install few games (I tried uninstall them). And one day data not started again. I restarted HD2, but it's not help. Well, after many tries, i came here.

I'm not changing operator and SIM-card (and i'm not touch sim may be half year).

I suppose, i must install my ROM clean. Configure all settings & programms. It takes a lot of time, so I'll do it on the weekend. (I have a small five-month child , so it's a little difficult). May be it's help.

I hope there is a way to do without this, may be look some things in special programs, or adb shell or something like that, and find out what happens, what is stopping him.

That's it.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Marvlesz:
Okay, I am sorry but I really don't know what the problem here is. Everything seems to me just fine. All I can recommend is going to MAGLDR because its data connections are stable (That is if cLK is actually the problem).

Other than that, I have nothing. Sorry.

I hope you get it fixed.
[HD2 Android Q&A, Help & Troubleshooting and Genera] alexfmos:
Well, If anyone is interested... I think i found "sticking point".

I backup my rom in cwm, and then started to experiment. (omg, i go to work sleepy). After uninstall all updates of "SuperSU" (and reset its settings) mobile data finally launched!!!

WTF was that? Don't know.
[Android Q&A, Help & Troubleshooting] masri1987:
d2vzw running Liquid Smooth 2.10 with BMS kernel, not sure what happened but while i was setting up rom, i lost information on /mnt/sdcard/android/data/com.banana.threenotes (catch notes data, such as images).

The crappy part is, it's on the internal storage, so i've tried some restoring methods and i've gotten nothing. Also, i've renamed the .nomedia file so that way media can be read (.nomedia is in the android folder).

Let me know if you guys\gals have any ideas. thank you in advanced-

This only seems to happen when i click on a notification in the status bar. the phone goes black, resets to home screen, then email works.

Anyone else have this issue? I see it's also an issue for other galaxy phones, just wondering if anyone with the note3 has resolved this.

I know what I am about to tell you is not going to fix the problem you're having, BUT just letting you know... I've been using Aqua Mail Pro on my Android for quite sometimes now, and I will NEVER, EVER use the stock email EVER! I'm a heavy email user but even if all I had was just my Gmail or Yahoo!, etc., still I would use Aqua. Many, many more features...
[T-Mobile Samsung Galaxy Note 3] jason370:
i like the stock email app for exchange mail , when it works, and mostly it always has and still does, except for this annoyance. ill give aqua a try. how is it on battery drain? i have fount k9 touchdown and EE to be big battery drainers.
[T-Mobile Samsung Galaxy Note 3] XooLoo:
Never have noticed a battery drain problem directly related to Aqua. Have had as many as 5 emails in it (with one being Exchange & 2 IMAP) with no problems...
[T-Mobile Samsung Galaxy Note 3] jason370:
Had trouble with exchange settings on it. Does it support exchange mail?
[T-Mobile Samsung Galaxy Note 3] dstarr:
I'm having the same exact problem. Do you have a galaxy gear watch?

Is your phone rooted?

Nobody else has this problem???
[T-Mobile Samsung Galaxy Note 3] jason370:
Yep rooted
[T-Mobile Samsung Galaxy Note 3] @rbiter:
Goto application manager and clear data. I had similar problem but related to different cause. Clearing my data did the trick. Hopefully helps you too.
[T-Mobile Samsung Galaxy Note 3] jason370:
Nope..didn't work

i have same problem and nothing has fixed it so far.... tried fix permissions, clear data, remove acct and clear data...nothing fixes it....any ideas?
[T-Mobile Samsung Galaxy Note 3] jason370:
I'm about to do a full wipe, although I can't imagine why that should help
[T-Mobile Samsung Galaxy Note 3] jason370:
this issue is killing me. i cannot access exchange mail without first having my phone freeze up and then getting this stupid error message. does anyone know a fix for this exchange email error/freeze up?

Argh!

It's a dependency that we froze in Titanium I bet. Same thing happened when I froze My Magazine and used TouchWiz.

We just have to find out which dependency(ies) it is.

Note 3 SM-N9005 (4G) same problem. Not sure if it was stuffed from out of the box as the first thing I did was root and remove stuff. Now same problem, freeze upon notification and then opens ok
[T-Mobile Samsung Galaxy Note 3] martinezma99:
Try these steps.

Unfreeze My Magazine (both files)

Unfreeze Polaris Office 5

Clear data and cache of Email app

Reboot

No more issues for me.
[T-Mobile Samsung Galaxy Note 3] njcobra10tha:
Touchdown by Nitrodesk is far and away the best mobile email program for Exchange I have ever seen.

Here are some reasons I love it:

Simple way to toggle between unread and read

View unread email from all synced folders in 1 simple list

Rules - When I was a DBA I would set a rule so my 4:30 AM email stating the Data Warehouse increased by $X was red and easy to find when I wake up.

Different Alerts can be set through rules based on sender, subject, keyword.

Great widgets

Great support
[T-Mobile Samsung Galaxy Note 3] jason370:
This didn't work for me. Same issue persists
[T-Mobile Samsung Galaxy Note 3] jason370:
It's a great program, but I hate the interface. Stock email and EE are my favs
[T-Mobile Samsung Galaxy Note 3] jason370:
Problem solved!

I searched for "SEAndroid" in Titanium Backup, and froze "Knox notification manager 1.0". Fixed.

Woo hoo

I'm confused by your instructions. You basically froze Knox Notification Manager? What does SeaAndroid have to do with anything?
[T-Mobile Samsung Galaxy Note 3] jason370:
I searched the web for the answer, and it kept coming up that "SEAndroid" was the culprit. So I searched "SEAndroid" in Titanium, and it returned "Knox notification manager 1.0"...which I then froze.

Boom, Fixed.
[T-Mobile Samsung Galaxy Note 3] asaqwert:
I can say that I have actually removed that program along with all other Knox related programs and still have the issue....still no exchange email notification love for me :(
[T-Mobile Samsung Galaxy Note 3] jason370:
Earlier, I followed the instructions (posted several posts prior) to restore Magazine and whatever else it said, i forget. It didn't seem to work at the time but perhaps there is some delay on that. Those were the only two mods I made and this problem is now resolved for me.

[T-Mobile Samsung Galaxy Note 3] asaqwert:
did you remove those apps again afterwards? i can definitely try it but i do know that when i re flashed the stock firmware it works fine now, so i'm going to try to remove things one at a time, with a backup copy of it in case, and see whats up. on another note, it's weird - when i flash the stock firmware through odin, it doesn't kill my whole device, it just sort of "dirty flashes" it... is that normal and do i have to do a wipe first? or whats the deal there?
[T-Mobile Samsung Galaxy Note 3] jason370:
I left them unfrozen, they don't bother me, and I consider it a gift from god that I was able to resolve this infuriating problem.
[T-Mobile Samsung Galaxy Note 3] dwitherell:
These odin files don't touch /data - my gut says this is so end-users using something like Kies can do an odin-based system update without having their data wiped - as I'm sure the idea of wiped data would keep a share of users away from updating when Sammy/T-Mo pushes updates. Just my thoughts, not sure if they are right though.
[T-Mobile Samsung Galaxy Note 3] statikk1:
I restored "my magazine" & Polaris office 5 and all is good.. the moment I freeze my magazine it goes stuffed again. Seems to be fixed.. just crap that my magazine app needs to be present in order to have email notifications work properly :(. Btw my magazine app needs Flipboard to actually do anything useful so my thoughts are to just "hide" the app until some better solution comes along. I will try the s4 email app on my phone. Same version number etc.
[T-Mobile Samsung Galaxy Note 3] Eric214:
I went through each app that was frozen and unfroze each 1 at a time until my email crash stopped from using the notification drawer. The culprit is My Magazine app.
