After updating to Nothing OS 4, battery backup reduced significantly.

Before update, phone lasted around 1.5 days.

After update, it lasts ~0.75 day with similar usage.

Heavy drain observed 2min 1%.

Issue persists even after factory reset.

Please optimize battery performance in upcoming updates.

Just updated my “CMF by Nothing Phone 1” to NOS4.0 and afterwards the gboard keyboard was too low on the screen. Here’s another user’s screenshot of the problem:

There should be a blank space below the keyboard to allow for the navigation bar and the extra buttons shown here. In this image pressing the space bar could be interpreted as the “home” gesture, while with the navigation bar displayed the bottom buttons are only a tiny sliver above the navigation bar.

It seems that the position information is incorrect after the update. This can be fixed by pressing the four-square button (above “Q”) and using the Resize tool to move the keyboard up slightly. You can drag the keyboard well above the navigation bar and then back down again, but cannot position it below the navigation bar again.

Hope this helps.

E_Monk Hey mate, sorry to see this has happened. Have you tried any troubleshooting steps, for example:

Reboot your device

If you’re still facing issues:

Go to settings > apps > google keyboard
Clear data/cache
Force stop
Reboot device

If that doesn’t fix it:

Backup
Factory Reset

And finally, if none of the above help I’d suggest contacting Nothing Support via https://www.nothing.tech/pages/contact-support and logging a bug report via settings > system > feedback.

E_Monk

hrry Restarting doesn’t fix it, and clearing the app data means having to re-train the keyboard to my preferences. Using the resize operation resolves the issue satisfactorily, as described in my post… which was primarily to assist anyone else who encounters this issue.

Hi Nothing community,

I’m reporting a reproducible network issue on CMF Phone (1) with Airtel, observed after recent Nothing OS updates.

Issue summary:

• Phone shows 5G connected

• However, daily 4G data quota is consumed rapidly

• Once daily data is exhausted:

          # 5G completely stops working

          # Unlimited 5G does NOT continue

Critical observation (with evidence):

While uploading Nothing network/debug logs (~142.79 MB / 0.14 GB):

• My daily data usage jumped:

          # from \~50%

          # to 90%

          # and then close to 100%

• Airtel sent multiple data-usage alerts during this short upload

• This data consumption is disproportionate to the actual upload size.

Images :

At the same time:

• 5G icon was active

• Network batching / aggregation was ON

This strongly suggests that:

• Data is being charged as metered 4G, despite 5G being shown.

Additional regression:

• Earlier versions had a “Smart 5G” option in SIM/network settings

• This option is now missing after update

• After its removal, this issue started occurring again.

Steps already tried:

• 5G enabled

• Manual preferred network selection (5G )

• Network reset

• Device restart

• Software up to date

Issue still persists.

SnapDark Same issue facing also the network is not stable.

SnapDark try other carrier… jio works fine for me… never switched to 4g after the latest update… i didn’t even enabled NR ONLY..

Airtel always causes problems with nothing devices…i saw almost every model of nothing has this issue …

If not done already you can try 5g only mode if that works for you… it keeps the device locked to 5g… dialer>star#star#4636#star#star>phone info>phone1/0 which sim slot you’re using>scroll down and find NR/LTE written on drop down menu and select NR only
