Android phones might get stuck on the startup screen. The problem might be benign, and clear after a few minutes. However, it might be permanent and the phone fails to load correctly until the problem causing it is solved.
This is especially true during updates from one Android version to a higher one. Besides getting stuck, the phone may keep restarting consistently and not getting past the brand's logo. This can result from a number of factors as expounded below. Depending on your model and the cause of the problem, there are a number of ways to fix the problem.
While most of the times the phone or tablet is stuck for a long time, there are times when allowing the phone a few more minutes is a good fix. However, there are lots of other factors that may cause this problem.
Android is a flexible operating system. The platform allows users to customize it any way they dim fit. The customizable nature of the OS allows users to unlock, root, flash and tinker.
Encrypting your Android device
If for any reason the user tampers with the Android system, there are chances of facing software problems such as delayed booting. Fortunately, the flexibility of Android allows it to accept different fixes and go back to the way it was.
Even with software issues, the system does not get completely inoperable. If the problem is due to changes in the Android system, standard fixes such as Factory Reset may not work. This is so as the problem is on the Android software. It, therefore, becomes vital for Android device owners to be careful with customizations. If customization directions are followed from an online source, it is advisable to follow the same instructions to redo the steps. Issues during the customization process can get out of hand.
When this happens, the best way is to start from the beginning of the process. If the customizations cannot go through, reverting to the earlier Android settings saves time. Before starting over again, switching the phone off and trying the customizations again, there are a few fixes to try as explained later on this guide. Updates are a common cause of Android phones getting stuck on startup just showing the brand logo.
Encrypting your Android device
This happens when the update did not complete as it should. Before an update starts, the Android device will notify the user of the duration the update will take. Most devices will let the user know that the process should not be interrupted. Even better, some Android devices will only allow the update to start after a phone has been charged to a certain percentage. This reduces chances of the phone going off during the update. When an update is stopped before it completes, the existing Android version is corrupted while the new one is not complete.
This means that the phone is left with no system to run on. There are a couple of ways to troubleshoot this issue as later expounded on this guide. If an app was recently installed into the device, there are chances that the app may not be compatible with other apps in the device or with the Android version.
When an app conflicts with the Android system and other apps or it runs outdated, it might cause a problem. This is especially true when an app is downloaded from third party sources and not Google Play Store. The app might be malicious or have a virus.
When troubleshooting Android system issues on a device, the first step is locating malfunctioning or malicious applications. When necessary, these applications should be removed. If removing the app does not help get the device to boot correctly, other troubleshooting steps should be followed.There is a caveat, though: As the name suggests, you need to put the phone in the freezer first. Cold booting or hard booting is where you reboot a system by cutting the power completely, and then turning back on.
When you restart a computer normally i. RAM is volatile, and it does require regular spikes of power to retain its data — but when power is cut, it actually takes a few seconds or minutes for the data to be lost. If you have some way of reading the RAM, you can extract all sorts of sensitive information — most notably, the encryption key used to encrypt the local hard drive or flash storage.Achromatic color wheel
This fault feature? Reading RAM is difficult, though. In the case of larger computers, you can physically transplant the stick of RAM into another computer, and read off the memory contents there.
Device encrypted but apps say otherwise
See: Full disk encryption is too good, says US intelligence agency. Now, as we mentioned, it can take anywhere from a few seconds to a few minutes for RAM to lose its data. One of the variables that causes this variance is temperature ; by cooling RAM down, it preserves data for longer. In a world where full disk encryption is the norm rather than the exception in criminal circles, the ability to recover encryption keys from memory is of vital importance to the FBI, CIA, and other intelligence agencies around the world.
It is now standard practice for some police forces to absolutely make sure that computers are not turned off during raids, until they have been fully scanned for encryption keys and any other data that might still be in RAM. There are defenses that can be employed against cold boot attacks, such as not storing encryption keys in RAM, but for now it seems that Android at least is still vulnerable.
Instead, it just sits at full brightness with no timeout! Whichever comes first. Man, that sounds grim. It sounds great in theory, security-wise, but in practice, the above-mentioned scenario makes this method incredibly inconvenient.
This is comprised of two different types of data:. With this, developers can also push certain files into this encrypted space, allowing things like alarms, phone calls, and notifications to come through before the device has been fully unlocked. That all sounds great, right? If you buy a new phone with Android 7. Because your current device is already using full-disk encryption, and this new method requires a full wipe in order to work.
Keep in mind that this will erase all of your data, effectively factory resetting the device! This, of course, depends on when you started running the beta—early adopters are probably still running the old full-disk encryption. File-based encryption and Direct Boot are really nice solutions to an extremely irritating problem. The best part is that it requires very little interaction from the user—on new devices that will be running Nougat out of the box, this should all be the default.

Thread Deleted Email Thread. My phone was stolen by hobos.Alina kabaeva children
I'm trying to see if there's a way to bypass the android secure startup. I was hoping these crackheads would take it somewhere to get a new rom for a different provider put on it and they wouldn't be able to and that would make me feel better.
I've done some googling on it but I couldn't find anything clear on it.Caratteri sconosciuti in cr 9
Clinton, IN. Thanks Meter : 4. Join Date: Joined: Mar So some people stole your phone, and secure startup is enabled, and you can't get in? Sounds like if it's YOUR phone, you would know the pass code and there's no issue. I don't understand how anything else in your post is relevant. If you have someone else's phone and your trying to ask XDA to help you break into it, sorry but no can do. And secure startup is part of the new encryption features starting with Android 6.
It's designed to keep thieves and hackers from gaining access to someone else's phone when rebooted. If you want to take a crack at military-grade encryption with some hex editor and hours and hours of coding, be my guest.

It only takes a minute to sign up. I was doing something in recovery mode a couple days later, I accidentally hit the "wipe all data on phone" button. I pressed no. I rebooted my phone and all of the sudden secure startup was enabled and it had a password instead of a pattern.
I tried a couple passwords but none of them worked. The attempts count only went down 1 time for some weird reason. I don't want to factory reset my phone. I just did a couple days ago, and I don't want to again. Well I've ended in same place as you but with entering number in a dialer. This one? My guess that this action wipes the encryption key so when you try to boot after clearing it prompts you this, and you probably need to enter key which I'm sure you don't know for this user and me too factory reset was only way out.
See this and this and this. I've read on a couple of forums where people have had the issue of their phone randomly rebooting and starting up to a lock screen that reads something like :. If you use a pattern code to unlock your phone, the PIN number will be the digits that your pattern lock follows.
I don't know how else to word it. Say, your pattern followed the corners tothen your secure startup PIN would be So, if you use a very complex pattern, it will just be every digit used that the pattern follows.

The first time PIN is entered is for decrypting and loading the operating system and the second time is for accessing the home screen.
Thus is more secure even though it's annoying to re-enter PIN again. Why would I want or need to enter my biometrics or passwords an additional time after secure startup? It is samsung OS concept.
I don't know other manufacturer's concept. However, for Samsung devices, regardless of any OS, that is how secure startup work.
