It was difficult to get the V600N, but there are several problems. 1. Fingerprint recognition is not possible. Although it recognizes fingerprint sensors, it seems to be a software bug. 2. Quick Pay, the function of LG Pay app, is not working. 3. Quick Help is the pre-release version. The pre-purchase requirement 1. VoLTE is available in Korea 2. Dual-screen execution is satisfactory, but the above problem is too fatal to use as a main phone. The next version of the current version (V600N08s4) is V600N09h, which is not possible to update OTA or to extract Kdz with LGUP. If you have V600N09h kdz file, please share it to me.
