comment How to Forget All App Passwords
Mobile apps (well-designed ones, anyhow) generally don't store your password anywhere, they use authentication tokens. In any case, I'm not sure a solution for this currently exists since it's up to each app to manage its own data. There isn't a system-level keyring or anything like that, so you'd either have to blow away each app's data completely or figure out where it stores tokens and the like (probably a database) and then wipe them out, meaning specifically programming against the apps you want to wipe the tokens from.

comment (Why) is it required to flash in order to install Google Play on CyanogenMod?
@Firelord I think that would also work. If I'm remembering right, that's how many of the Play Store installation guides for the Fire TV Stick explain it, because it has no custom recoveries currently. Flashing is usually just easier, I suppose.

comment (Why) is it required to flash in order to install Google Play on CyanogenMod?
There actually is an important feature only available to system or trusted apps: the ability to install other applications without enabling the "Unknown sources" option. I think Play Services relies on other system-level permissions as well, but I don't know any off the top of my head (/cc @Firelord)

comment Android devices not allowed to connect to WiFi
You should probably talk to your IT department. Without knowing a lot about the network configuration there won't be much we can do for you.

comment Nexus 5 stuck at Google screen after failed(?) rooting
If all else fails, flashing a factory image from fastboot will generally solve boot issues. NB: If you do want to re-attempt rooting, that version of SuperSU is super old - it probably won't work. The latest (stable) version looks to be 2.65.

I'll be a bit more direct than Izzy: you appear to be completely unqualified for a moderation position. You have no demonstrable relevant experience. Your platform of "I'd just like to see what's going on in the mod tools" borders on a joke/trolling. I cannot conceive of any reason to vote for you. I would strongly urge other voters to support a different candidate.

comment Is Android device able to connect with Android Wear devices through local Wi-fi network without internet access?
I'm not sure if this varies by device, but the Moto 360, for example, supports notifications via WiFi.

comment Android system Webview installed but not used by apps
@AaronGillion I'm not sure. My guess would be that it will hinge mostly on whether or not Google's WebView uses APIs that were introduced in 5.0. If not, then you might have a shot at getting it work, but if it does then it'll crash.

comment Android system Webview installed but not used by apps
@Clémentine Google's control over third-party manufacturers is somewhat limited. They probably could opt to use Google's closed-source WebView just as Nexus devices do, but they may choose not to for whatever reason. I'm not sure of the specifics regarding how Google licenses their closed-source applications to OEMs, but those terms (whatever they may be) could be a factor in the manufacturer's decision.

comment Android system Webview installed but not used by apps
@Clémentine Nexus devices (possibly others) ship with it pre-installed, and configured to use it. It is, in effect, the system WebView for those devices.Thus, Google is able to provide WebView updates for these devices via the Play Store so that full system OTAs are not necessary just to update the browser/WebView. There are other components that Google has migrated to Play Store updating in a similar fashion, with the reasoning essentially being that it is faster.

comment Does full device encryption protect my data from Google and the government?
@JimThio Probably, but only if you had access to the system or ADB while booted. Otherwise you'd have no way to actually make use of the root permissions. Alternatively, a custom recovery would allow you to update the firmware.

What actually happens when you swipe an app out of the recent apps list?

comment Why does my Moto G 2nd gen show H and not LTE?
The 2nd gen Moto G comes in a bunch of variants. The US models don't support LTE, only the Asia/EU ones do. You'll need to figure out what specific model you have (possibly in your device settings) then you can compare it to a list such as en.wikipedia.org/wiki/Moto_G_(2nd_generation)

comment Does full device encryption protect my data from Google and the government?
I would add, I'm not sure if the general delay per attempt is something that can be "disabled" by an update, or if Android scales it artificially. Android uses scrypt rounds during the key generation process, so it would need to be used when decrypting the key as well, and scrypt is designed specifically to be difficult to speed up, as a mitigation against brute-forcing. That much would remain consistent. A lockout after X number of failed attempts (or a scaled lockout, if one exists) would be implemented in software, though, AFAIK.

comment Does full device encryption protect my data from Google and the government?
@Bob To my knowledge, Android does not require the decryption password to perform the update process, because it only encrypts the /userdata partition, not the partitions that the update would actually be modifying (/system and /boot, generally). It's pretty much in the same boat as the iPhone 5 (and lower).

comment Does full device encryption protect my data from Google and the government?
@Bob The encrypted data itself couldn't be decrypted by a ROM update alone. You would still need the key (I'm not sure if that was what you meant by your second question?). As for flashing a weakened ROM, as long as the device's bootloader is locked it would be basically the same as the iOS situation - only OEM signed updates will install. Also, unlocking the bootloader to try to flash an unsigned image would wipe the device.

comment Does full device encryption protect my data from Google and the government?
@beeshyams It's a feature of the processor. ARM's implementation is called "TrustZone", but other architectures also provide similar mechanisms. The idea is that you can generate a device key, store it in a place only accessible to the TEE, then never reveal it to the outside world. When you need to encrypt/decrypt something, you ask code running in the TEE to do it for you, so the key remains secure. Wikipedia has a decent(-ish) article.

comment marshmallow and personal security/privacy
Encryption keys are never stored in the cloud on Android, and I seriously doubt they were for iOS. iCloud's backups can be encrypted, but that's a completely different key and the goal is to keep the data safe while it's at rest on Apple's servers. Storing the device encryption key in the cloud would be an incredibly poor design.

comment categorization of reviews on playstore listing
Pretty sure the count is the number of reviews that used the bolded words (i.e. of all the reviews the app has, 2,152 used the word "useful"). They're basically showing you which words or phrases are most commonly used when describing the app. Don't have a source for that, though.
