Sd card

If a SD card ejects itself from time to time while another card works fine, you should stop using it to prevent data loss because maybe some of its internal blocks have worn out. This problem could happen to SD cards with low capacity eg. 8gb or 16gb if they have been used daily for a couple of years.

Autonomous Cars: Not Yet Ready for Prime Time

I'm sure that crosswalks are easy to detect, and so only flagging pedestrians when they are on those will be a simple programming problem.

But everyone involved in authorising that, and in authorising a vehicle with that programming to travel on the road, and who didn't inform the safety driver of this limitation (because I'm sure they didn't), should be sacked and face charges. That's unforgiveable (though if you'd asked me 2 years ago to guess which company would have cut a corner like that Uber would have been top of my list).
I look at it as an inherent risk in trying to program human thought into a machine. Humans have to think of everything they think of (and stuff they don't think of which is more scary) in every scenario and adequately program that into some machine.

And I'll circle back to saying the biggest impediment to self driving cars becoming mainstream will be lawyers. Was it incompetence or negligence? Who's incompetence or negligence? Was it really a foreseeable event? Was the critical failure the vehicle manufacturer (SAAB), the operator (UBER), the safety backstop (the human whatever), or any one of the many sensor manufacturers, developers, and whatnot. There are more than enough ambulance chasers out there to make self driving cars so cost prohibitive up and down the supply chain that it just won't work.

Help Is there a way to do this?

Welcome to Android Forums, Dwarvo!

The weakest link in this scenario is, as Hadron pointed out, the wife--not the phone's security.

I can't think of a single approach, including combinations, e.g., fingerprint plus PIN, that will guard against the wife giving the daughter the code. You said the daughter takes the phone at night. What's to stop her from holding her sleeping dad's finger on the fingerprint scanner? Right, nothing!

Really, your friend's best solution is to stop telling his wife his code--either that, or put the phone in a safe at night...but I'll bet she knows its code, too...

Help How can I know the date when I save someone in my contacts?

The contact was saved in your Google Contacts? I'm not a WhatsApp user so I have very little knowledge about it, but I'd have to assume that WhatsApp must have permission to read and write contacts, and that WhatsApp has a trigger to automatically add contacts. If it bothers you, you could revoke the permission from WhatsApp or find the setting to turn off automatic contacts.

As far as finding the time of the contact, you'd have to contact the developer of WhatsApp and see if there's a log for app activity being written.

New math

I kind of wondered the old age antie "Never trust anything you have read" makes me wonder, if you read and believe in everything, then why does it always lie to other people, why we must lie to each other like that instance? Maybe there is a hotline for the world of errors? Could of be the hackers own fault??

Help Samsung s9 note keeps going back to home page

You're welcome! :)

So it sounds like something recent has caused this [annoying] problem. Can you recall any new apps you installed around the time it started? Take a look at your app history (which should show newest first) and see if that jogs your memory.

What you can try is uninstalling, in reverse order of how you installed them, any apps that may be the culprit. One by one see if that fixes it. (And if you zero in on the guilty app, please post its name here, and post on its Play Store page, explaining what it did. These will help others.)

Since the problem started several months after a factory reset, I agree with @ocnbrze that that may be your next step. I know it's a hassle, but if it fixes the problem, it's worth it. Be sure to save any important files before factory resetting.

Thanks I'll post updates if I fix the problem.

Help V10 Boot Loop

I know you might loose everything,But try a factory reset.
Master reset with hardware keys
A master reset restores the original factory settings and may delete your personal data on the internal storage, such as downloads, ringtones, images, apps, contacts, and Visual Voicemail. It does not delete data stored on the SIMcard or SD card.



If the device menus are frozen or unresponsive, you can master reset using hardware keys.



  1. Back up all data on the internal memory.
  2. Turn off the device.
  3. Press and hold the Power and Volume down buttons on the back of the device.
  4. When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
  5. When "Factory data reset" appears, use the Volume down button to highlight Yes.
  6. Press the Power button to confirm.
  7. When prompted to "Erase all user data and restore default settings," use the Volume down button to highlight Yes.
  8. Press the Power button to reset the device.
This did not work for me because it just reboots and stays stuck on the LG logo splash screen for several hours and never get's to the main icon screen. Is there any resolution to this madness?

Apps Android in-app purchases huge drop

around 70 now 3-4. But english countries are ok
just some asian countries the purchase rate dropped so much. Probably Google play they are trying some design chanegs or button etc whatever hope it will be fixed.

@mikedt did you see some changes on google play when purchasing ?

I haven't needed to purchase any apps this year, so I wouldn't have noticed any changes. When I did purchase I used a Google Play voucher I bought in the UK. I actually live in China, and Google Play isn't available here officially.

Trying to send a calendar to my daughter

I'm assuming you are sharing a Google calendar?

Open your Google Calendar in Chrome https://calendar.google.com and in the left column you will see a list of your calendars (My Calendars). Click on the three dots next to the calendar you want to share and select 'settings and sharing'. Under the 'Share with specific people' section you should see your daughter's email. If you see it, then you're all set.

Now, your daughter must also go to her calendar page and accept your invitation and then turn on your calendar to display. Once you do that, then she should see it.
