Does the nothing team read the problems that we write in this community post post. I also tried mailing them and gave a feedback and also shared my problem, but they said go to the nearest service centre.

How to rollback to the previous version as the current update version for nothing phone 3a i.e. 4.O has been creating issues with regard to fast draining of battery.

Requesting you to kindly provide a solution at the earliest as it has been only 3 months since I bought this phone and it really hurts to see my phone in this condition.

For everyone facing the draining battery issue or another major issue, I personally suggest to open a ticket and send the logs. I think if the team receives official queries they will have a real estimation of the trouble.

Anyone plz help me, with this update my camera app really went broke it can’t take selfie clearly 6 or 7 out of every selfie or camera sample is a disaster. Selfies come blurry most of the time, photos get badly processed sometimes oversaturated sometimes very blurry sometimes details are missing. The thing is I only rely on this phone for some good photos and now it started betraying me after the update 😭🥲
