Phone broken in Japan

Yesterday evening,my phone got knocked off the table at Pronto and fell screen first onto the ground. The screen is cracked and the LCD is broken, however I still receive notifications for messages and things, so the phone itself is ok.
It's a Samsung A30, and no one seems that nobody fixes Samsung here, especially if it wasn't purchased in Japan.
I don't know what to do. I don't have a residence card (since I am only in Japan for an internship of 8 weeks) and Irelyheavily on my phone for communication with my coworkers, translating and google maps.
If anyone has any advice, please reply.

I live in Fukuoka-shi, and finding english speaking people to help is almost a miracle.

I know it's annoying, but renting a phone for the next two months might be the easiest and most convenient option.

Buy a new fone

1) order screen from Amazon, Aliexpress etc. and replace it by yourself. On internet you can find explanations how to do

2) Go to google maps and find a phone repair shop and check if they can replace the screen

3) Buy a new phone sim free in Japan (cheap) and repair your phone when you go back

The A30 is a lower end phone and typically parts and repair are Not available on those. I think that phone is US$250 full price, which is about what it costs to get a Galaxy Note screen fixed.

I�fd just buy the cheapest new phone option you can find locally to get you through. I wouldn�ft plan on finding a repair when you get home either though, for reasons stated above.
