Question about Dalvik cache! - Samsung Galaxy Note 8 Questions and Answers

Hello, can i clean the Dalvik cache on my running ROM? Sometimes after Month of using, Apps run laggy and Phone runs laggy. Or is this option only for a clean install and i shouldnt touch this Option on running ROM and only clean Cache Partiton?

You can clean the dalvik cache whenever you want. It won't affect the day-to-day working of your device. It also won't speed it up or make it snappier again if it starts feeling slow. You can clean it, but it'll functionally make no difference. It's like wiping off your screen and expecting your device to look more clear and sharper.

Unusually slow G1 maby looking into changing ROM [SOLVED]

Not only a wipe but a FULL wipe, that will likely fix it and yes Super D is one bad ass Rom. I recommend ver. 1.10.2 at this time however until some problems are worked out on the latest one.
Wipe data, dalvik, ext, battery stats
reboot recovery,
wipe data, dalvik, ext
repair sd:ext (in partition on amon ra recovery)
flash Super D v1.9.3 WG Kernel
http://forum.xda-developers.com/showpost.php?p=5732507&postcount=1
then
Super D 1.10.2 on top
finally reboot

I agree, this can help others not to make another thread with the exact same issue.
I used to have a very slow G1, even with minor widget usage (stock 1.6 i believe). I tried out a lot of custom ROMS and am now rocking HTCClay's remixed SuperCSDI v4, and i must say... its hella fast.
But watch out for the Pure Messenger Widget! The widget itself is awesome, but on 4x4 it is clearly bogging up my phone to a point where it takes 4 or 5 seconds to return to the Home screen (i find this irritating).
I have never tried SuperD and am willing to try it out. I see i need Danger SPL, right now i have the ENG SPL. Do i need to change or does SuperD work with the ENG SPL as well ?

[Q] need help removing a "tweak"

my nephew had my hero for about 2 months and started putting aosp and cyanogenmod roms on it, which i don't have an issue with, but he installed a "tweak" made by a now infamous "user". (i don't think i need to say a name, everyone knows who i'm talking about). i have been searching to see if there is an uninstall method, but since the dude's account is closed, i cant find a way to get rid of the tweak. do i have to RUU and re-root in order to get rid of it, or is there a way to do it so i don't have to go thru resetting the phone up? any help would be greatly appreciated.
...xfrobex
from the aosp GB wiki.....
you need to wipe/format your phone, in clockwork recovery: Wipe data/factory reset, wipe cache partition. Under Partitions menu (or Mounts & Storage in 3.0.0.5) in recovery: Format boot, system, data, cache. Under advanced: wipe Dalvik Cache.
Then re-flash your rom/gapps. I suggest using titanium backup and backing up your apps, also.
I believe that is the only way to remove the tweaks .
Yup wiping and reflashing will take care if it as chin has said
®parallel universe®
Thank you ch1naski, i appreciate it. I'm glad it is going to be that easy, i was about to back-hand my nephew if i couldn't remove it.
Lmfao. I bet your nephew is really thankful.
Root/Hack-Mod_Always *
Yeah, he is. But I did tell him he will get the smackdown if he doesn't nand before flashing anything else. Hopefully that will get him into the habit of nandroid-ing whenever he tries anything new
u dont really need to wipe anyhting if your on cyanogen or aosp just reinstall the rom itself and thatll return the build prop back to normal.

This may very well be true.... I personally find it more comforting to go fresh when there may be hidden tweakisms lurking about...clear the pipes, so to speak.

Just reflash your ROM. I would try a dirty flash first, but if you encounter problems, you should do a factory reset.

By factory reset you mean flashing the rom with wipe?

and by the way the factory reset won't solf my battery problem. tried it before.

Yes that is what i meant.
Dirty flashing means, that you flash the ROM without wiping first.
Regarding your battery problems, you can always try different kernels. But make sure you let the system settle, before you jump to conclusions. How is your battery life exactly?
or try this...
use your pc to install another launcher from Google Play (nova, apex etc). let it install, then press the home key. your phone will ask which launcher to use. select whatever it is that you got from Play. don't select 'always use'.
then go to settings>apps and wipe data/cache for htc sense. reboot, press home and select sense. see if that helps.
if not, dirty flash is the way to go.

Check out Elemental X Kernel. It supports thermal throttling.

[Q] Broadband Signal loss

It all started a month ago. I wake up and my phone has yellow letters and stuff in front of my screen and zero signal. I googled and found out about factory mode and such(root disable etc) and i managed to get it off my screen but the no service problem persisted. So again I learned through your great forums how to flash stuff how to unbrick etc. I managed to get a clean install with official samsung firmware after a lot of tries which means i installed a lot of extra stuff i dont know. So now I have signal but is not as strong as it used to be. In some occasions where eveyone has 4 bars i have 2. Or in closed places like a coffee shop where everyone has 2 bars i either have zero or no service and when someone calls me says that my phone is turned off. I noticed that the kernel hasnt changed, i might have installed a kernel that doesnt match my Model. I have a GT-I8190N android version is 4.1.2 broadband modem is I8190NXXANK1 and numder of construction is JZO54K.I8190NXXANK1. I always thought that the firmware brought its own kernel but i rly dont know. Should i flash the kernel I8190NXXANK1 you have on your site? With which app should i do it? Do i have to root again and get twrp just to flash that file? Isnt there any way to flash the kernel without rooting and without twrp like with odin for instance in download mode? Thanks in advance. Forgot to mention that when i try to flash the kernel with factory phone recovery its says signature verification failed.
Try install it through Odin, just like flashing firmware, but only wipe cache and dalvik cache before and after flashing. Ignore the system,data and internal/SD card partition(don't wipe them).
You need to find kernel .tar file,(flashable thru Odin, as .zip file can't be flashed by Odin).
You might want to look on the hardware side too.
Good luck

Thank you for your reply. I did install twrp because i couldnt wait and i installed the kernel through that. Still no changes. I replaced the antenna(im a hardware expert,software is what is killing me) with a brand new from the same model. Still 2 bars. Remember I have signal its just not strong enough as it used to be. So i think i might have flashed some junk while i was trying to learn how to flash like some weeks ago. Now i really dont know how to "wipe cache and dalvik cache before and after flashing. Ignore the system,data and internal/SD card partition(don't wipe them)." Is it by opening the recovery and choose "wipe data etc".Thank you for being interested in my problem. All I want is to have the signal back. Isnt there a way to FLUSH(delete/wipe) like everything. Every corruption or bad script and just bring it to factory. If we cant do that then can I install a custom rom that will overwrite the corrupted stuff and ill have full signal? If u know any good custom rom i would gladly flash it. May god( which i dont believe in ) take years from life span and give it to u if u help me fix this!

There a wipe button in TWRP, tap it, find advance wipe, chose cache and dalvik only, swipe, and its done.
If you suspecting an app is the reason, just uninstall the app, but if its a script, you need to check with the dev how to deactivate/kill/delete it.
But as I know, if you do a factory reset and wipe data partition, your phone will be just like a new phone just come out from factory, only basic firmware is present( its 'factory reset' right )
There is a lot of custom ROM in the forum, need a little reading to know if its got what you want.
And carefull bout posting something other than android or device, as it is stated in the forum rule. Better pray no mods or op see this.

Could it be the fact that im using XX code and im in greece? All my friends in greece have XX and they have no issues.... I think something is wrong with the hardware but might be the motherboard itself... Where i work there is a lot of humidity, so maybe it cant be fixed. Oh well ill buy a new one if that is the case. Thanks again for your time.

A ROM question

Not gonna ask the best ROM, as everyone gets a bit uptight about those, and feel the need to defend "their team" and all that...
My question is more generic, in that I am wondering if there is even a ROM out there that will meet MY needs... so if I list those things that I would need in a ROM, maybe someone can simply answer yes or no and point me in the right direction?
Here is what I would be looking for in a ROM:
1) Stability, has to be as stable as stock, no screens of dead or random reboots
2) Speed, zero lag, fast and fluid
3) Everything has to work. If it works on stock, be it apps like VZW Visual VM or whatever, it needs to work on the ROM
4) More polish and eye candy, nice animations, make the device beautiful to use without being buggy or laggy
5) Battery life at least as good as stock
If there is a ROM that gives you all that, has a bit more customization but not so much that it takes half a day to set it up, what would it be? Or would I be better served just using a different launcher?
I have not installed a ROM in a couple years... I was a flashaholic for awhile, but a few phones that I had in a row worked really well in stock form, and some had locked bootloaders that never got cracked, so I kinda gave up on them for while and so my knowledge is a bit rusty...
What I don't want to do is go to the trouble of installing a new ROM and having it not work, or be buggy, etc... This has to be daily driver quality and I want to USE it, no spend too much time fiddling with it.
Ideas?

Cool. And I am sorry if this is a dumb question, but like I said, it has been a couple years since I installed a ROM...
I can use Wug's Nexus toolkit to install a custom recovery, and then take the downloaded ROM and recommended GAPPS files, go into Recovery, install ROM, install Gapps, then factory reset and I am good to go?

I don't personally recommend toolkits unless you have ADB/fastboot knowledge and experience but otherwise yes. You don't need to factory reset after ROM installation, just do the required wipes, generally listed in the OP of the ROM you choose, in TWRP, prior to flashing.

Got it, just installed it. Put the ROM and Gapps in a folder and I will first make a Nandroid of my current setup... Then I will try it out.
The OP for that ROM doesn't have any instructions, but you said that in TWRP that I need to wipe cache and stuff PRIOR to installing the ROM? I always thought you did that last? Am I remembering it wrong or did something change?

For your first installation, wipe, used advanced wipe, then select dalvik, cache, data, and system. Then flash your ROM. Updates to the same ROM can usually be "dirty flashed" by simply wiping cache and dalvik prior to installation.
Tried it out, but found that it was slower in Antutu by 3,000 points and it was a bit laggy at times... Weird.
I wouldn't hold a ton of value or base anything off Antutu.
Sorry if I didn't pay attention to time stamps between your posting. I did look at your stats and see you have plenty of experience here. May just need to give a bit of time for ROM to settle.
I have tried several ROMs here and consider there to be a BIG 3, or the most popular. I won't say the names due to the fact that I don't want to place any one above the other. However, I would recommend a ROM with Layers.
When you go to wipe prior, wipe all but internal storage. I wipe twice, just because I am OCD. Flash all necessaries and sometimes an alternate kernal will help, but give baked in kernal a chance. At least a cylcle or two. Wipe the Davlik and Cache after flash, as TWRP suggests.
There are a few to choose from which are close to stock without overdoing it. Most things folks want to do to customize can be done with apps in Play Store without over loading file size of ROM.
OK, I'll say it, but I don't want you to think I am partial. Try Chroma

Oh trust me, I have no concerns with people being partial. Some people get bent out of shape in "best ROM" debates, but I don't. I WANT to know which ones are top tier, and why, from people that have used them.
I know that Antutu is not the end all be all... But when I saw it was laggy, I run that to see if it is just placebo, and sure enough, it was slower and there was a little stuttering and lower frame rates in the final 3D game test... I just use it as a reference point, that's all...
I played with Layers a little and didn't really get much out of it... It just seemed to change the color a bit on menus and things, so I didn't see a lot of benefit.... or am I missing something?
I will take a look at Chroma and see how that looks, thanks.
