Mobile AI isn’t Netflix, so phone makers need to keep subscriptions out of it

Add as a preferred source on Google

When I reviewed the Nothing Phone 3a Pro I loved the phone and was also taken by the Essential Space, the brand’s subtle and useful move into mobile AI. However, as the Nothing Phone 3a Pro finds its way into more hands, some hardcore users are hitting a limit in Essential Space where they can no longer use the AI feature on the phone.

This frustrating situation is causing alarm because any kind of AI feature limit is often followed by a subscription option to remove it. If Nothing does start to charge heavy users for the Essential Space, will anyone be prepared to pay? It’s a question every smartphone brand should be asking about mobile AI, and the answer may not be the one they want to hear.

What’s going on with Essential Space?

Nothing’s Essential Space is a cool feature. It’s like an AI-assisted note pad, where it stores, categorizes, and organizes screenshots taken on the phone. In the future you’ll be able to add photos to its library, search by voice, and more to aid your memory and keep all those handy notes in one, easily searched place. It’s a bit like Samsung’s Now Brief in terms of life organization, but without the deep integration with your calendar.

It’s activated using a dedicated button on the Nothing Phone 3a Pro, showing Nothing’s commitment to it as a feature. However, at least one user posting to Reddit was surprised to come across a “monthly processing limit reached” warning when using Essential Space, and being unable to continue using it. The responses to the post are all negative, and none seem to suggest the feature is worth paying for, should such a system be put in place. Digital Trends contacted Nothing for comment on the situation, and a Nothing spokesperson responded with the following:

“It’s been encouraging to see so many people using Essential Space since the Phone 3a Series launch. As a result, we’ve increased the initial usage cap to a level that will comfortably accommodate the vast majority of users. Essential Space is a new feature that we’re incredibly excited about, and we are focused on refining the experience based on user feedback.”

While we enquired about potential future costs for users, Nothing did not address these concerns, and for now it seems like there are no solid plans to introduce such a scheme. However, the processing limit warning for Essential Space has reminded us some AI features included with our phones today are going to require a subscription in the future, and how at the moment, they don’t really offer enough value to enough people to justify one.

Why would it need a subscription?

Why should Nothing and other brands want people to pay at all? AI features often use the cloud to process data, and Nothing states it does send data to the cloud where it’s processed and then deleted when it has been analyzed. Outside of mentioning several future Essential Space features, including a meeting transcription feature which recognizes different speakers, it does not mention any personal data limits, or the potential for subscription charges in the future on its website.

AI services can require a massive amount of data to operate, and you can eat through it quite quickly too. For this reason it’s common and accepted for major AI services to charge heavy users a subscription fee to make full use of the AI’s capabilities. OpenAI’s ChatGPT can cost up to $200 per month, while Google’s Gemini Advanced and Microsoft’s Copilot Pro cost $20 per month for example.

Even as a light AI user, I can see the value in paying for extensive, varied AI services like Gemini Advanced if you regularly use them. However, much as I liked Nothing’s Essential Space, I’d have to take a lot of screenshots and be very forgetful to make it worth paying for every month. Plus, when you’re faced with a subscription (another one), you instantly assess whether you really need it, and this is where mobile AI begins to fall apart. The niche services, usually locked to a device or user, are nice-to-haves, not must-haves.

It’s not only Nothing’s problem

Nothing isn’t the only one facing this problem. Samsung has already said some of its Galaxy AI suite of features will require payment to use in the future, and by releasing them all for free now, it hopes we’ll have already become reliant on them by the time the day comes. It’s unlikely all Galaxy AI features will be behind a paywall, and you won’t be forced to pay, but will you want to pay at all?

Some of the features are good, but good enough to pay for? No, not really. Now Brief, Samsung’s organizational tool, promises a lot but only delivers if you’re utterly reliant on your phone’s calendar, and busy enough to require regular reminders and suggestions on how to cram more into your day. If you’re not, it doesn’t do much.

How often have you used the translation features on your Samsung, Asus, or Oppo phone? What about AI photo editing or image generation? Nothing’s Essential Space is a cool feature which doesn’t push the AI element too hard, making it friendly and fun. But it’ll stop being fun if it gets a cost attached to it. Apple Intelligence is currently free, but an iCloud-style subscription fee is possible in the future, according to reports.

Compelling enough?

Are any mobile AI features compelling and useful enough for me to pay for them each month? No, not yet, and if they were, when a subscription looms, I’d take a good look at all the other options available before considering paying. It’s where Gemini Advanced, ChatGPT, apps providing similar features, and other AI-powered tools will start to make a lot more sense. They’re potentially more focused, more versatile, often usable on the desktop and mobile, rarely tied to a single device or manufacturer, and will probably be available to the whole family too.

At the moment, mobile AI is a collection of features on a single phone looking for subscribers, rather than brilliant features people will be happy to pay for, and it’s a distinction I don’t think manufacturers understand. It’s going to cause a problem as the almost inevitable subscriptions start to arrive, and Nothing’s Essential Space is evidence of the reaction they’re likely to get.

The Pixel 11 is almost here, but I’m more excited about what could come with it

It’s August, which means one thing if you follow smartphones even remotely closely: new Pixels are almost here. Google is holding its next Made by Google event on August 12, and this year, we’re expecting another packed lineup of phones. The Pixel 11, Pixel 11 Pro, Pixel 11 Pro XL, and Pixel 11 Pro Fold are all expected to take the stage. Yes, that’s the same four-phone lineup Google gave us last year, but the interesting part will obviously be what’s changing underneath. Between the usual camera improvements, new hardware, and whatever AI tricks Google has been cooking up, there should be plenty to talk about.

And the phones may only be part of the story. Google is expected to have a few more announcements up its sleeve, making this one of its biggest hardware events of the year. So, if you’re planning to tune in, here’s when the Made by Google event starts, how you can watch it, and everything we expect Google to announce.
