Originally published on the MyTreda engineering blog: read here A support message described what looked like one confusing mobile bug. It turned out to be two independent ones — a cross-site cookie getting blocked by Safari's ITP, and a React Hook Form autofill desync — that just happened to both only show up on mobile. Full breakdown, code, and fixes below.

A helpful comment on my EXIF test suggested using a metadata scrubber. That is useful for ordinary still images, but a mobile upload contract must define every asset it sends. An iOS Live Photo can include both a photo resource and a paired video resource. The failure case is simple: the JPEG derivative has no GPS EXIF, while metadata or an original file associated with the paired video survives in the upload or retry path. Build the resource inventory first: let resources = PHAssetResource . assetResources ( for : asset ) for resource in resources { print ( resource . type , resource . originalFilename ) } Then make privacy assertions per output, not per UI selection: Artifact Required check still derivative no EXIF GPS/location fields paired video derivative no location metadata upload manifest only derived filenames retry queue no path to original resources temporary directory deleted after success or cancellation My lifecycle test would start an upload, force the app into the background after the still image is prepared, kill it while the paired video is processing, and relaunch. Recovery must either regenerate both safe derivatives or delete the incomplete pair. It must never mix a scrubbed still with an original video. Apple’s PHAssetResource API exposes the resources associated with a Photos asset. That enumeration should become evidence in the test: fail when an unexpected resource type is present rather than silently uploading it. Also verify what reaches the server. Device-side inspection alone misses multipart manifests, queued originals, and server-generated previews. Download the stored pair in a test environment and run the same metadata assertions again. A “remove location” button needs a precise scope. For Live Photos, the user reasonably expects it to cover the complete paired asset and every retry copy—not just the JPEG they can see.

A subscription audit should survive contact with a real app. So I started with mine. TurnTalk is a live iOS travel translator with in-app purchases. I operate the app and its RevenueCat implementation. That makes it a useful public example, but not a customer case study. I will not claim a conversion lift I have not measured. Here is the first finding I would put at the top of its audit. Evidence: the store page introduces several different jobs The subtitle makes a focused promise: Understand Any Guide, Live But the first screenshot sequence spreads attention across: AI travel translation Voice translation Photo translation Instant translation Each feature may be useful. The issue is not feature quality. The issue is that a visitor has to decide which product TurnTalk is before deciding whether to download it. A traveler who wants to understand a live tour guide is evaluating a specific job. A visitor comparing general translator apps is evaluating a much broader category. Those users arrive with different intent. Why I would rank this before a paywall redesign The paywall cannot repair ambiguous acquisition intent. If the store page attracts people for four different jobs, aggregate trial and purchase rates become difficult to interpret. A low conversion rate could mean: The paywall is weak The first session does not prove the promised value The visitor downloaded for photo translation but reached a live-translation flow The listing attracted broad curiosity instead of durable travel intent Changing the paywall first would alter one screen while leaving those explanations mixed together. That is not a clean experiment. P0 action: make the first three screenshots tell one story I would test a narrower opening sequence: Situation: You joined a tour, but cannot understand the guide Mechanism: Put in your existing earphones and start live translation Outcome: Hear the guide in your language without staring at the screen Photo translation and secondary conversation mod

How I Built a Block Puzzle Game with React Native and Expo A few weeks ago, I launched my first mobile game — a block puzzle called Blockbeam. It's an 8x8 grid where you drag colorful blocks, fill rows and columns, and chase high scores. Simple concept, but building it taught me a lot about React Native's capabilities beyond typical CRUD apps. Here's what I learned. Why React Native for Games? Most mobile games are built with Unity or native code. But for a 2D puzzle game, React Native is surprisingly capable. The game doesn't need 60fps 3D rendering — it needs gesture handling, state management, and smooth animations. React Native handles all three well. The key stack: Expo SDK 54 — managed workflow, over-the-air updates, zero native config react-native-reanimated — 60fps drag animations react-native-gesture-handler — PanResponder for drag-and-drop react-native-svg — block rendering AsyncStorage — game state persistence The Puzzle Engine The core of any block puzzle is the board state. I used a flat 64-element array for the 8x8 grid: const BOARD = 8 ; const CELLS = BOARD * BOARD ; // 64 type Board = number []; // 0 = empty, 1-7 = block colors Piece placement is straightforward: check if all target cells are empty, fill them, then scan for complete rows and columns to clear. The interesting part was the "greedy solver" I built for the auto-play bot. It tries every piece in every position and picks the move that clears the most lines: for ( const piece of tray ) { for ( let r = 0 ; r <= BOARD - piece . h ; r ++ ) { for ( let c = 0 ; c <= BOARD - piece . w ; c ++ ) { if ( ! canPlace ( board , piece , r , c )) continue ; const score = simulateClear ( board , piece , r , c ); if ( score > bestScore ) { /* pick this move */ } } } } Drag and Drop with PanResponder The trickiest part was the drag mechanic. Each tray piece has a PanResponder that tracks touch position and renders a floating ghost. On release, it calculates the nearest cell position: const anchor = { col : M

Leaker Evan Blass shared images of Samsung's redesigned Galaxy Z Fold 8 just days before the July 22nd launch event where Samsung is expected to officially announce the phone. The leaked images show a shorter, wider foldable matching earlier leaks of the Z Fold 8. They also reveal some of its specs, including a Qualcomm […]

OpenAI introduced GPT-Live on July 8, 2026 and describes it as a full-duplex voice architecture: it can listen and speak at the same time. GPT-Live-1 and GPT-Live-1 mini are rolling out in ChatGPT Voice, while API availability was described as coming later. Primary source: OpenAI, “Introducing GPT-Live” . Full duplex changes the mobile failure surface. The app may hold microphone input, play output, detect interruptions, and continue background work concurrently. A polished desk demo does not answer what happens when a phone call arrives, Bluetooth disconnects, the app backgrounds, or permission changes. This is the test plan I would run before shipping a full-duplex voice workflow. It is a plan, not a report of measured GPT-Live API behavior. Record the environment device : " physical device model" os : " exact OS version" app_build : " immutable build" voice_model : " product/model label visible during test" audio_route : " speaker | wired | bluetooth" network : " wifi | 5g | constrained" battery_start : " percent" low_power_mode : false microphone_permission : granted background_permission : " record actual setting" A result without device, route, and network context is difficult to reproduce. Define observable states idle -> connecting -> listening <-> speaking -> reconnecting -> paused_by_system -> ended -> error Track three channels separately: audio input — is the microphone active? audio output — what route is speaking? task state — is a delegated/background operation still running? The UI should never imply “listening” after the OS revoked microphone access. Interruption sequence Use a harmless scripted conversation and timestamp every event: T+00 connect on phone speaker T+10 user speaks while assistant is speaking T+20 switch to Bluetooth headset T+35 background the app for 30 seconds T+65 return to foreground T+80 trigger an incoming call or system audio interruption T+95 decline/end interruption T+110 disable microphone permission in Settings T+130 retu

Flutter State Management in 2026: Riverpod vs Bloc vs Provider in Production Every Flutter team eventually hits the same wall. The app works, the demo looks great, and then somewhere around screen thirty the setState calls start colliding with each other, a widget rebuilds three times for one tap, and nobody on the team can explain why a loading spinner is stuck on a screen the user already navigated away from. That's the moment state management stops being a "nice to have" architectural decision and becomes the thing standing between you and a shippable product. We've built and maintained Flutter apps across fintech, e-commerce, logistics, and healthcare — different domains, wildly different feature sets, but the same recurring question from every engineering lead we work with: Riverpod, Bloc, or Provider? There's no shortage of opinions online, and most of them are shallow — "Bloc is too much boilerplate," "Riverpod is the future," "Provider is basically deprecated." None of that is useful when you're the one who has to live with the decision for the next two years of feature work. This is a practitioner's comparison, not a popularity contest. We'll walk through what each of these actually does under the hood, where each one falls apart in production, and how we decide which one to reach for on a new project. Why state management is the architecture decision that matters most In most application frameworks, state management is one of several important decisions. In Flutter, it's disproportionately important, because Flutter's entire rendering model is built around widget rebuilds driven by state changes. Get state management wrong and you don't just get messy code — you get a slow app, because unnecessary rebuilds are a real performance cost, not just an aesthetic one. There are three problems every state management approach in Flutter has to solve: Where does state live , and how does a widget deep in the tree access state that was created somewhere else? How do

As 9to5Google points out, leaked images and specs for the upcoming Galaxy Z Flip 8 shared by WinFuture are nearly identical to Samsung's current flip phone. According to the leak, Samsung is not planning to upgrade the Z […]

Twelve years after the launch of the OnePlus One, OnePlus announced today that it has exited the United States. It's bittersweet, as the brand has been on a comeback tour of sorts with its excellent OnePlus 15 and widely praised (though still too expensive) OnePlus Open. The writing has been on the wall for a […]

GitHub announced on July 8, 2026 that GitHub Mobile can start a Copilot cloud-agent workflow to fix pull-request merge conflicts. Primary source: GitHub Changelog, July 8, 2026 . The unsafe mental model is “tap once and the conflict is solved.” A safer model is: mobile intent -> bounded remote task -> proposed patch -> verification -> human merge This is a source-based checklist, not a hands-on product assessment. Exact controls and permissions must come from current GitHub documentation. Record the handoff repository : " owner/project" pull_request : 123 base_branch : " main" expected_base_sha : " <commit>" expected_head_sha : " <commit>" allowed_scope : - " src/example/**" - " tests/example/**" forbidden_scope : - " .github/workflows/**" - " deployment/**" required_checks : - " unit-tests" reviewer : " <responsible human>" expires_at : " <UTC timestamp>" This operator artifact is not a representation of the mobile UI. It preserves intent across interruptions, network changes, and the delay between delegation and review. Before handoff, confirm repository, pull request, branches, expected files, sensitive paths, required checks, and the person responsible for merge. Never place secrets, customer data, or private incident details in the instruction. A bounded instruction is better than “make CI green”: Resolve conflicts between the recorded base and head revisions. Preserve documented behavior, limit changes to the listed paths, do not modify workflow or deployment configuration, and return a patch without merging. Verify the returned revision the result belongs to the expected repository and pull request; base and head revisions still match the handoff; every changed file is expected or explained; no conflict markers remain; no workflow, ownership, deployment, or policy file changed unexpectedly; tests ran against the exact reviewed commit; tests were not weakened or removed; a human can explain the semantic choice made for each conflict; the reviewed commit is the

If you've searched the App Store for a reliable third-party QWERTY keyboard on iOS, you know how that ends. Some are abandoned. Some are ad-riddled. Some feel like they were ported from Android and never touched again. The good ones are the ones that don't ship features so much as they don't crash. The system keyboard is fine. It's fine because Apple has been iterating on it for fifteen years. Nobody else has. Third-party keyboards on iOS are a graveyard. I'm building one that isn't. It's called Diction. Most people know it as a voice keyboard, and that's what I lead with, but under the hood it's a serious low-level QWERTY project too. This post is about that half of it, because that's the half nobody talks about. Why third-party QWERTY on iOS is a graveyard Building a good keyboard extension on iOS is hard. There's a strict memory ceiling. There's a permission dance the user has to opt into. There's no keychain access, no meaningful background work, and the extension can be killed the moment iOS decides it needs the RAM. Most keyboard makers ship a first version to check the box, then abandon it once they see how much work maintaining it takes. The result is what you see on the App Store today. Every third-party keyboard I've tried on iOS fails on at least one of these: Speed. You type a letter, the letter arrives. That's it. If there's a hitch you can feel, the keyboard is broken. Half the ones I've tried have a visible delay on every keystroke. Predictability. If you correct the same word back three times, that word should be yours. The keyboard should stop fighting you. Most never do. You fight the same wrong correction for a year. Recovery. iOS keyboard extensions are memory-constrained. Bad ones freeze under pressure. When you rapid-switch between apps, half the third-party keyboards on the store will lock up until you kill and reopen the host app. Autocorrect that isn't from 2014. Fix the obvious typos. Split words that ran together. Complete contractions. Ge
