J7 Verification Failed Error
Problem: My Samsung J7 rebooted itself and when it turned back on the operating system stops at a black screen with this message “Verification failed. Unable to restart your device. The integrity verification has failed. You need to reset your device to factory default settings. This will erase your data.” and a Reset Device button on the bottom. I do not want to reset my phone to factory settings. I need to save the photos, texts, opened browser tabs, etc. My T Mobile store says that I need to reset my device. Basically, when I restart the phone, first the Samsung J7 shows up, then the page, then TMobile page, then the screen dims slightly, there is a little vibration in the phone, then the dreaded message shows up. I booted the phone to Android Recovery startup and tried to WIPE CACHE, which did nothing. I will try anything. If you can help me recover my information, photos, etc on the phone, I will be forever grateful. Thank you
Solution: It looks like the phone software has become corrupted. If wiping the cache partition of the phone fails to fix the problem then you should now consider doing a factory reset from the recovery mode. If you perform this step though your phone data will be deleted.
In case the issue persists then you will need to flash the phone with its updated stock firmware file using Odin. You can get the firmware file from the Sammobile website which is also where you can get the instructions on how to flash your phone.
J7 Keyboard Lag when Typing
Problem: Firstly the buttons seem to get stuck as I am typing. The letter bubbles hang around for a long time, as though it can’t keep up with my typing ( which the speed is average at best). ( this mostly happens in skype, but it has begun to happen in other apps). Today, the keys began to stay highlighted long after I ve pressed them. Is this a keystroke virus??? Is there a processing problem via touch to bubble to showing up on screen? It began doing this about a week after I purchased the phone. I do have a Lot of memory used but nothing super crazy and the phone doesn’t lag anywhere else.
Solution: If the lag only occurs whenever you type then the first thing that you should do is to clear the cache and data of the keyboard app from the application manager. Once this is done check if the issue still occurs. If it does then proceed with the additional troubleshooting steps listed below.
- Start the phone in Safe Mode then check if the issue occurs in this mode. If it doesn’t then the problem could be caused by an app you downloaded. Find out what app this is and uninstall it.
- Wipe the cache partition of the phone from the recovery mode.
- Backup your phone data then do a factory reset.
J7 Screen Not Responding After Drop
Problem: i dropped my samsung j7 on the tarred road and screen got cracked. now phone is switching on and has a black screen and can’t respond to touch what could be the problem how best can i solve have a tight monetary budget
Solution: Because the screen has already been physically damaged then the best way to proceed in this case is to have the display assembly replaced at a service center.
J7 Screen Is Black
Problem: I’ve dropped my phone a couple times and it’s never been an issue before. I’ve had the screen replaced a few months ago and it’s been operating fine up to that point and since then. I dropped a week ago from a foot off the floor and nothing cracked and it operated fine afterwards. I used my phone all morning to make phone calls and email, and then browsed social media for a while as well. When I went to work I charged it for 45 mins and then placed it in my back pocket. I used it a few times during my shift, and then after work when I ran a quick errand before coming home. I hadn’t been on my phone at all after I came home. It remained in my pocket for 3 1/2 hours untouched as I moved around the house. I didn’t sit at all at work, and when I did sit at home while it was in my pocket, I tucked my right leg under me and sat on it on the side where my phone was in my pocket. However, I was sitting on my bed and have sat like this many times before without their being any issues or damage to phone. Is it possible that I could have flexed the screen or the phone as a whole and that’s why the screen is black? I can’t think of anything else I could have done that would cause the screen to react this way. When I first got my phone out to check my notifications, the screen acted like it was having a seizure and showed green and pinkish lines in a “T” shape throughout the screen. It would do that for a second and I couldn’t get it to stay on for more than a few seconds. It would flash the lines and go black. It would try to turn on, and acted like it did so successfully, besides that my screen would turn black. The notification light comes on, and my back arrow and menu button on the bottom left and right corners of the screen light up when the screen is on and unlocked. The battery wasn’t low, it should have been between 80-60%
Solution: The best way to troubleshoot this problem is to first check if it is caused by a software glitch. To do this you need to start the phone in recovery mode. If the screen works in this mode then I suggest that you do a factory reset. Take note that the reset will erase your phone data.
In case the issue persists then this is very likely a hardware related problem already possibly caused by a damaged display or display connector. The best thing that you can do right now is to bring the phone to a service center and have it checked.
J7 Does Not Start
Problem: Hi there. Pretty sure you may have covered this, but i have a J7 which just won’t turn on! It’s fully charged (i plugged in and it says ‘100%’) but every time i press the power button, all i get is intermittent flashing of the logo and it never actually boots up. I’ve tried the system re-boot (power, up volume and home buttons) a but with no luck…..any ideas if this can be fixed easily??
Solution: Try starting the phone in recovery mode then from here perform the steps listed below.
- Remove the microSD card of the phone ( if you have one installed).
- Wipe the cache partition of the phone.
- Perform a factory reset. Take note that the reset will erase your phone data.
