Merry Christmas! I am coming to you with this topic because you have the following problems: soft update F (x) tec pro 1 (version 2019). Why update: security level 05.04.2020 (in a few days we enter 2022), android update 9 android 10 (at least).It is an 800 euro phone, not 1 euro, in value.And how toninstall the Linux for this phone? As a main phone I have Ulefone Armor 12 5G (bought on 1.10.2021, cost 300 euros) android 11 specifications, quad camera, 48 mpx, the last update was yesterday 26.12.2021 (security level). Put the bone to work starting with 03.01 .2022, it's a shame to throw away
