  1. downloaded on s3 i9300 huge battery drain aswell as screen flickering browser crashes very slow charge also..charged all day at work 10hrs to full then depletes in almost under 4hrs… minimal core apps ie missing calculator and alarm ect on +side extensive developer options

  2. installed CM13 on my S3 i9300. Here are some of the issues I have noticed.

    Screen flickers from time to time.
    Browser crashes and stops when trying to download any content/file.
    Camera: in 16:9 aspect ratio there is a green line on the side of the camera interface.

  3. The screen flickering issue is fixed but I don't know about the browser and file manager bug because I don't use them. But the phone hangs and crashes a lot even after updating it daily! I went back to cm12.1 because cm13 used to hang and crash a lot! I'm waiting for the hanging issue to be fixed.

  4. Hocam bende de hata var rom u kuruyorum kurulumdan sonra dil seçimini yapınca kablosuz ağı seçme kısmına geldiğimde klavye hatası veriyor bir türlü düzelmedi kaç sefer format atmak zorunda kaldım bilgisi olan var mı?

  5. i installed cm13 on i9300. browsing sites with alot of content is extremely slow. also when opening alot of apps the phone becomes slow and unredponsive… untill it crashes and restarts

  6. I have installed CM13 in my S3. Overall good performance but few issues found after I update received via OTA on 19th Mar.

    1. Screen flickers from the time I install CM13.
    2. Camera gets hanged and it shows complete dark and it doesn't capture anything even if you press the button. Had to restart to get the camera work everytime.
    3. Gets hanged when this camera issue happens and also gets hanged while using applications like facebook, flipkart, etc.

    Thought today's OTA update 21st mar would clear the above problems but it is still the same. Please help fix.
