Dalvik / Cache
So I'm a tad confused between dalvik and cache. Are they the same thing? I've seen people refer to clearing "dalvik cache" and both individually. Also, when you do a factory reset from the recovery menu (home + pwr), does that wipe the data and clear the "dalvik"?
I'm curious cause I would like to completely wipe everything off of my phone and start a new and I'm not quite sure the best steps to take
Thanks!

Hi All !
When I try to find a text on a web page using the stock ICS browser or plus, it crashes ? Is there a fix/solution ? (not change browser...)
Thanks in advance
Why did you create this thread in the Dev Section? Reported.
OP, Development section is just for that, please post your questions in the Q&A sections. Thank you, thread moved.
Try go into "Settings > Apps > All", find Browser, click on it and do "Clear cache and data".

do this and boot to CWMR and also wipe dalvik cache and cache partition, Reboot recovery/system and check on your stock browser again.

Unfortunatly it does not work...
There are many ROMS with this problem...
What ROM are you running? What kernel? Etc. Yada Yada.
If you run what your signature is stating, have you already thought of "upgrading" your kernel/ROM combination?
Hi
I recently downloaded 2.12.29 Official MIUI ROM from http://miuiandroid.com/community/threads/2-12-28-29.19143/
However, after flashing, when I reboot the phone, the phone stucks at HTC white screen for a couple of minutes and then reboots into recovery..
The only strange stdout I see during installation is :
>> format system
>> do not formate system
Has anyone come across such issues.. are there any known workarounds..
Help appreciated..
EDIT: I follow the following steps for flashing:
1. Factory reset
2. Wipe cache
3. Wipe dalvik cache
4. format system
5. install ROM
6. wipe cache
7. wipe dalvik cache
8. flash boot.img
>> 6,7 because I read on one of the MIUI forums that if the ROM is flashed on a phone already running an MIUI then these steps are required..
Looks like issue is resolved after following the documentation at: http://miuiandroid.com/community/threads/how-to-update-upgrade-miui.15424/
Mainly caused by not properly following the steps below
1. Boot into CwM or TWRP recovery.
Wipe cache, dalvik cache and data.
2. Flash rom.zip. and Reboot.
Allow tab up to 20 minutes (usually takes much less time) to reboot to the initial Setup screen.
Complete the initial setup (CM Account setup is optional).
3. Go to Settings, and enable Developer Options, allow installation from Unknown Sources,
enable Android Debugging, enable Advanced Reboot, etc. and then Reboot.
4. install GApps.
My experience is that the most important parts are
A. wipe cache, wipe dalvik cache and wipe data, if you are not sure, you can do this every time before flashing any .zip and before booting. It won't hurt to wipe it many times.
B. make sure completed configuring all the setting on step 3, including "allow installation from Unknown Sources", before install GApps.
If you believe any step is not right or not necessary, please let me know.

Since a while i wipe cache and dalvik cache again after installing GApps in step 4 and till now it works perfectly.
PS: i dont wipe data every time in step 1, execpt it is a major Rom update
New Verizon S6 Edge (sitting in the box for 1-2 years) and I used the OEM adaptive fast charger to bring it from zero to 100% and then waited 10-15 minutes.
I used the built-in OTA updater, not Samsung/Verizon's Software Upgrade Assistant, and went through 11 system updates over the course of 2-3 hours. Out of curiosity, would using the SUA have reduced the number of updates to apply? Edit: I am almost certain now SUA updates straight to the current build (based on their wording, link at bottom). Apparently if I wanted to go straight to current system build, I should have used SUA or a tool such as Odin to flash the stock firmware directly.
Here is a list of the software builds I went through:
G925VVRU3BOG5 - This was the build on my phone out of the box.
G925VVRU4BOG7
G925VVRU4BOG9
G925VVRU4BOK7
G925VVRU4CPC2 - This is the first official build of Marshmallow for this phone. After update success, I decided to wait a few minutes and then restart the phone.
G925VVRU4CPD2 - I received error 404 after automatic download failed. Manual download attempt OTA was successful.
G925VVRU4CPF4 - I received error 401 after answering no to the automatic download request because I was trying to prevent the error above. Manual download attempt OTA was successful.
G925VVRU4CPH1
G925VVRS4CPI2
G925VVRU4CPK2
G925VVRS4CPL3 - My battery charge ticked down from 41% to 40% just before I applied this update, 35% upon completion/success message.
G925VVRS4CQA3 - This is the last Marshmallow build available for this phone.
On Verizon's webpage it says to have at least 40% charge or 20% when hooked up to the charger. I am worried because I did not connect my phone back up to the charger for these last two updates. The last one really bothers me because it was 34% when applied and 29% upon completion/success message. Is there a way to verify everything was written correctly? Should I even be worried?
With exception of a few failed downloads, all updates -when applied- said successful first try.
I have the understanding that it is important to wipe (system) cache partition and wipe data/factory reset from the recovery menu after major system updates to avoid all sorts of potential problems. So, here are my questions:
Does wipe data/factory reset from the recovery menu also wipe (system) cache partition? If not, should I wipe cache partition before or after? I have found conflicting information on this. Edit: It is so confusing because when you search around there are tutorials only mentioning the reset, others saying to wipe cache before reset and vice versa! There are also people going as far as doing both of these before -and- after a system update! Edit 2: It appears that wipe data/factory reset formats /data, /cache and /sbfs partitions. So, wipe cache partition is redundant when performing a factory reset from the recovery menu.
Both of these videos demonstrate wipe cache partition followed by wipe data/factory reset. You will see /cache is unnecessarily formatted twice (picard facepalm).

Note: there is no Google account to remove (Factory Reset Protection/FRP, Google Account Lock etc) as this is a new phone.
I am under the impression that I should clear all app cache, app data and maybe reset network settings before I attempt the recovery menu methods above. This is overkill/redundant, right? Edit: All this stuff appears to be stored in somewhere in /data (even an app's cache, within a subfolder of each app).
Aside from backup (in my case does not apply), is there anything I should do before (or after) recovery menu wipe(s)? I want to ensure clean slate. Edit: It seems wiping /data and /cache is all you can do in terms of user-accessible data.
I notice there is a "Factory data reset" option from within the OS under Settings: Backup and Reset. Does this behave any differently from the recovery menu method? Edit: I found via thedroidguy.com that it does not reformat the /data partition as the recovery menu reset does but only clears it. It also has Backup and Restore options. Are there any other differences? Does it clear other partitions than /data?
Also, I notice in Settings: About Phone: Status there is "Factory data reset". For me, it says "Unknown". I assume this value is a counter, log or timestamp of the last known factory data reset(s). Maybe it is only triggered when the reset is performed within the OS, but I have no idea. Anyone know what this really is? Will a recovery menu factory reset trigger it?
Under Settings: Storage there is Cached Data. If I clear this, does it include all application cache -and- all application data or just the app cache? Edit: I am pretty sure now it just clears all applications' cache, so it shouldn't affect anything unless maybe an app is poorly coded and stores things in cache that should be elsewhere. On a related note, when clearing app data from apps individually its app cache will also be cleared. I am not sure if clearing Cached Data from this Storage menu touches the system cache partition.
Any documentation or links would be very much appreciated; I am running out of steam here sifting through search results with different keywords and modifiers.
If anything I said is wrong or not entirely correct please say so!
