I think iqoo is intentionally degrading performance of iqoo neo 7 pro by not giving very basic features like battery health,fps meter bcoz they know this is the last android support for the device.funtouch os 15 in qoo neo 7 pro feels like a 10k phone after the update.so much lag, fingerprint issue,touch issue,speaker sound became very low and battery draining like it hell and so much heating issue.Android 14 was best software for iqoo neo 7 pro.Android 15 downloaded and installed automatically, otherwise I would have never updated the device.
