Hi, I just purchased a BV9500 and it is currently too unstable to take over where my old phone is leaving off. I have flashed the newest rom from this forum twice, updated all the apps on the phone, disabled all the unnecessary apps, made sure power saving is off, turned off all animations in developer options, installed a new keyboard to replace the one that kept crashing, turned duraspeed both off and on, and tried many other little tweaks. Despite this, all apps that I try to run either freeze and restart the phone, or simply crash and give me the "keeps crashing" notification. Additionally, background apps and processes such as google play services continually crash, launching notifications constantly.

As of now, the phone is unusable, and I will keep my sim card in the old phone.

Is there anything else I can try to make this phone usable?

Has anyone had any luck putting a different operating system such as Lineage OS or AOSP on the phone?

Thanks for your time and help!
