Btw, if your main device is Samsung and it supports FEH, you can use Samsung SideSync to play FEH on PC without any worries! A little bit laggy, but for sure it's one of the most safest method.

Yup! It works! Thanks a lot!

I will try this out! Interesting... How safe is this method?

I wish I could pull Reinhardt +Atk\-Spd with that luck... but I couldn't. Btw, I fully uninstalled FEH from MEMU (with data\cache wipe), reinstalled it and right now it's working again. Made one Tempest run to check.

Today I got 803. Right now I'm on the same boat as you, guys...

Ok... First of all I carefully followed video instructions to install it all on my desktop PC... Right after this video I did some stuff: Changed settings to make MEMU looks like a real phone and add some stability to it (look at attachments). *IMPORTANT* Installed FEH after I made all the settings! (Untick "Root Mode" before installing FEH matters!!!) Game asked to update Google Play Service or something like that... I logged in my google account and then google play crashed, I tried second time and this time it decided to update. :) Loged in into the game, linked my nintendo account, downloaded game data and... ??? PROFIT! Made one Tempest run to check. Everything seems ok! P.S. Sry for my english... I do my best!

Yeah, 3 days on a row on my notebook without 803 error... Just carefully followed his instruction. I will try to do it on my desktop PC to notice what I have done differently. I will write back later then.

I've been playing for 2 days without any 803 error

This method works for FEH as well: https://www.youtube.com/watch?v=LTjXQUmTEHs
