hey mirek, thx for ur amazing work. tablet is not even warm for me and battery life aprox better about 50% onscreen on not heavy use. heavy usage like gaming has a bit of improvent. but my tablet still does not recognize sd card formatted in ntfs/exfat/fat32/ext2/ext3/ it just does not see… however it will recognize any non XC sdcard. pls look more into this because at least 2 people I know has this issue. also my bios is 1.05 kdc6 model. If you have some buggy and unstable build feel freee to sign me to beta testing team. cheers
