Getting worst after update latest firmware #106

![Uploading 263702988...] Before update it was smooth, no more delay. After update firmware it really hard to detect the reader.

User reports that since upgrading to the latest firmware via the GUI from @GameTec-live, reader detection is poor. See the attached videos of a Chameleon Ultra vs Flipper Zero

Apparently this was not the case with stock firmware.

i doubt that its the guis fault because it just takes the fw from gh

User has tried disabling animations to see if this makes any difference, which shows no change in behaviour:

I agree. Not trying to apportion blame, just stating what he's said in the Discord channel.

It was suspected it might be a clash between HF and LF in a single slot, so here is Slot 8 with only LF:

The blue light indicates that the LF simulation is working. From the factory firmware to the latest firmware, the LF simulation has been modified many times, which may have caused compatibility loss of some readers.

i don't know if it can be useful, but if you look at the white RF LED, it doesn't always turn on and sometimes it turns off immediately instead of staying on
