Android Reviews

451 Play Store reviews · TB 374 · K-9 77 · 31 languages
⚠️ Play Store Rating Drifting Away from 4★ Annual Goal

Q1 trend: 3.95 → 3.91 → 3.81★ (TB-only). Push notification failures are the primary driver — 19 → 23 → 31 negative mentions across Q1 and still accelerating. Two new friction signals entered the top issues list this month: spam filtering and v17.0 crashes.

Desktop Forum — Top Signals  — click a signal to read the full story in the report

Signal Questions MoM Context
Gmail / Google 69 +23% POP3 issues, cert errors, antivirus conflicts, folder repair — highest-volume provider
Yahoo / AOL / AT&T OAuth2 55 +38% Yahoo's change broke TB < v148, forcing upgrades; users confused by OAuth2 browser redirect
GMX server incident 7 +250% Provider outage — not a TB issue; resolved when GMX fixed their infrastructure

Recurring theme: lack of in-app troubleshooting tools (opt-in telemetry, crash logs) makes diagnosis hard for volunteers and staff.

Android Forum — Top Signals  — click a signal to read the full story in the report

Signal Questions Context
Desktop parity (font size, unified folders, scheduled send) 4 Font size control removed in UI revamp; unified folders and scheduled send missing
Filters like Desktop
↔ Play Store: Spam Filter Absent — #2 friction point, 10 neg mentions
3 Message filtering rules ask; Play Store users hit the same gap as a spam problem — same missing feature, different entry point
Crash on v17.0 (Android 8 + images)
↔ Play Store: #3 friction point, 6 neg mentions · K-9 44% of crash reviews
confirmed ~80% of image emails on Android 8; works on Android 12+; fix expected v17.1/v18 · Forum volunteers have workaround (older F-Droid build) that Play Store reviewers never received
⚠️ Push / Notification Sync — absent from this forum

The #1 Play Store friction point (31 negative mentions, accelerating all Q1) is not surfacing as forum questions. Users hitting push failures appear to be leaving reviews rather than seeking support — no resolution path, higher churn risk.

Recurring theme: no Troubleshooting Information equivalent on Android; SUMO is hard to use on mobile, keeping question volume low.

⚠️ Community support numbers are under review — methodology may shift slightly next month as we iterate on data collection.
