Data gone after adding a new SD card and formatting as internal storage

I’ve just added a Samsung EVO 128GB MicroSD card to a Fairphone3 and formatted it to “internal storage”

After that WhatsApp is not able to find media any more and pictures located in “DCIM” seem to be vanished.

However when I inspect the storage devices in the Android settings it looks like a lot of the space of the SD card – as well as the internal storage are in use.

Stragely Android reports the SD card to be 256GB instead of 128 – while gparted tells me the correct size.

Is there any way to find out where my data has gone?

android – Best Project for Card Game App

I want to code an app so my friends an I can play a card game while we are in quarantine. The game in question is the game of mus (a spanish game of cards).

Is there another open source game (preferrably on github) which I could use to build my game on top of?

Needless to say, I will give proper credit to the authors.

PS: In principle it should be an android app.

Where can I get a SIM card at the Hyderabad (Telangana, India) airport, or somewhere on the way to Banjara Hills?

Pre-activated SIM cards are not sold in India. This means you have to buy a SIM card and then wait for some time for the number to get activated (this can vary from 2 to 24 hours). To buy a SIM card, you can visit official outlets of Indian telecom operators – Vodafone, Airtel, BSNL or Reliance Jio. There are a number of such stores in Hyderabad. A simple Google search for “Vodafone store” or “Airtel store” in an area will show you your closest one.

To buy a SIM as a foreign national you need to submit some documents. This article has a nice overview of the process. From the article:

If you want a prepaid (pay-as-you-go) connection, visit the nearest Vodafone, Airtel, or Reliance Jio store in India with the following documents.

  • Passport, with a photocopy
  • Photocopy of the visa
  • Passport-sized photographs (usually just one needed, but carry four just in case since telecom operators require four photographs in some Indian states)

The executive at the stores will guide you about the exact documents but I feel you may need to submit proof of local address (like a hotel reservation) in addition to ones mentioned above.

Also remember that your existing device may not work for frequencies at which Indian operators work. You can find complete frequency bands here.

graphics card – Why laptop GPU’s are smaller than regular PC’s GPU’s

Maybe this is a stupid question to ask, but I was always wondering, why laptop graphics cards are significantly smaller than pc ones. Let’s compare Laptop with RTX 2080 Super

And some regular RTX 2080 Super – RTX 2080 Super sample image

And regular RTX 2080 Super is quite a bit bigger than the laptop itself. This laptop isn’t even 3cm thick, where the only GPU seems to be exceeding that.

As I know, in Laptops only GPU main chip is soldered on (And VRAM ye ye ye…) But then the next question rises up. Why we can’t just make some kind of GPU socket on the motherboard, and that would make PC’s a lot smaller, excluding that bulky GPU PCB.

probability – Expected Value of Decreasing Sequence Card Game

I encountered this problem when studying (interview), and would like some insight:

What is the fair price of a game in which you shuffle 9 cards labeled 1 through 9 then keep choosing whether to open the next card or stop given that you will receive the sum of the last decreasing sequence?

Here are the assumptions I’m making:

  • You only have nine cards total, one of each number.
  • There are no single digit sequences. Hence, if the current draw order is 9-8-4-2-3, the last decreasing sequence is 9-8-4-2.

I’m honestly not sure if there’s an easy way to go about this problem without brute forcing every possible sequence?

java – Bank Card Generator Code

This program is used to create a random bank card number. Card number is created using account type and client location for the first eight digits and the remaining 8 digits are completely random. I’m new to this site, but I believe it’s just for code review to get opinions on code. If i’m incorrect please let me know and I can take this down. Otherwise, feel free to give me feedback. Thanks!

sd card – BitTorrent downloads have reset to zero percent, how can I recover the parts already downloaded?

using BitTorrent on phone, I moved several downloads to the SD card, using the ‘move torrent’ option in the app. as I have done many times before without problem. I changed the SD card for another reason and then put the original sd back into the phone. when I restarted BitTorrent, the moved files were showing as 0% downloaded. If I go into the phone to examine the files, they show the size downloaded, as do the BitTorrent parts files. However, the app still shows as 0%. how can I get them to resume downloading from the previous point and not from the beginning? Many thanks

usability – What do you think of this redesign of a resultpage card?

I am wondering about a redesign I have been doing. It is about a resultpage in which we have home insurance cards.. the current setup was not flexible enough to show a longer text for the usps.

enter image description here

My goal for the redesign is to have three clearly separated colomns of the card

First section is for the companys name and rating
The second section is for the USPS and product information
The third is all about pricing information

I am also hoping that the new card is better scanable

Home insurance

I have also another version in which i have placed the grey tablets below the product name.. this is perhaps easier to scan?


Any suggestions are welcome!
