*Screenshots of camera are 1.8mb png files and not 180kbyt like normal ones -.- can't upload them direct will edit later*
I own an Xperia Z2 and I am a college student. I would like to record my lectures but whilst recording 4K video the ‘camera’ overheats after 4-7 min of use. I have tried recording in full HD, but after 30-40 min the ‘camera’ would once again overheat (I put my phone on flight mode and power saver to get the recordings this long). My lectures are between 1hr-2hr long so I am looking for a way to prolong the overheating pop up for at least 2 hrs.
As far as I have understood in your posts undervolting should reduce the heating as the less power is used. However, I haven’t rooted my Xperia yet and haven’t installed any kernels either. I have noticed that you link the heating pop-up problem occurring with the overheating of the processor. I have done tests (around 4 times whilst recording 4k) and it seems that once the CPU temp reaches around 72 Celsius the camera shuts down.
1.Wouldn’t it be better than if I installed a ROM which contains nothing (bare minimum apps) and ran the camera application on it? (CPU wouldn’t have to use resources for background applications so less heat is produced)
2.If you installed a custom mod for the camera app such as http://forum.xda-developers.com/xper...-mbps-t2845265 could this potentially if the bitrate was put down, increase the time able to record? (The CPU would be less stressed out as less information to process)
3.Also which kernel for undervolting do you recommend? (Sorry if you mentioned it before but I don’t quite understand the kernels)
4.Which kind of boot loader did you use for undervolting? (Once again I apologize if this has been mentioned somewhere before but I am not good with technical terms)
These are my phone specs:
3 GB RAM
16 Internal memory
128 GB micro SD card
Processor info: Qualcomm MSM8974PRO-AB
Android version: 4.4.2
Kernel Version: 3.4.0-perf-g35f9635
Build number: 17.1.A.0.314
