[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] leovarghese1232:
Hey Derpfest team,

Awesome work with this custom ROM!. It's surprising to see how we could get to experience A12 in it's pure form in OP7T (color OS bye bye!) and without much issues through your hardwork! But this ROM isn't without its bugs, and would like to comment in detail about them so that you guys can iron them out in future builds.

Call quality. Able to hear the recipient well, but since the mic is generating some disturbance on its own, it muffles my voice to the listener. I do not think this has anything to do with the SIM card in use. But can be taken up for investigation.

App Drawer. At times after opening app and later closing it from the recents, I can’t reopen it once again from the drawer. It seems as if I click on an image of an icon, rather than app icon itself. Also, the app drawer sometimes changes color to the previously extracted color from previous wallpaper on its own. Another issue is on scrolling the app-drawer upwards, I notice a slight friction, due to which it seems the drawer is lagging. Also in the tab section (personal apps + work apps), the tab labels tend to overlap the app icons, making it look weird. I usually restart the launcher to solve this (happens quite often).

Launcher: Delay in showing the option bubbles on long press of icons.

Charging estimate time is weird. It's all wrong (charging gets done in an hr, but still shows as 9hrs left)

Microphone adds noise to the recordings I do (even if the background is totally silent). Mic needs lot of optimizations.

Settings. Clicking on various options in Settings, takes half a second more to open.

Lockscreen: In lockscreen, pulling down the notification tray, I noticed stuttering. Also, just after unlocking the phone, I notice 2-4 second lag in overall phone usage. At times this lag still exists, and so I restart the phone.

Proximity Sensor. It works, but, when I take my phone away from the ear during a call, the brightness of screen comes back in 2 steps instead of one, due to which it feels like a lag.

Fingerprint takes 2-3 attempts to unlock. It's that the sensor isn't able to accommodate my finger fully. Sensor hardware is working perfectly though. Software front requires optimizations.

AOD: At times AOD doesn’t get dimmed. It gets stuck at the same brightness level as the phone’s brightness currently has (I donot use adaptive brightness). This is usually noticed when I unlock the phone using fingerprint. I speculate that the software has to handle the bright portion of the screen (for fingerprint area) and the rest of the screen properly, without affecting FOD’s ability to detect fingerprints.

Camera. I know custom ROM’s camera is a notorious situation. I use GCAM mod, and the results are quite good, but not as great as how out-of-the-box camera was in OOS. I hope we can together crack this code of software optimization to solve this camera situation in ROMs.

@matt0301 I'll be more than willing to provide any kind of logs needed to fix these issues. Just let me know the steps for it. Also, I myself am an engineer, so I can assist you if needed to get this ROM to stability. Coz this ROM really has potential.

Thanks :)
