How Did Global OS Trends Shape Mobile Apps in Vietnam in Q2 2015?

Released on July 15, 2015 by Appota Joint Stock Company, the Q2 2015 report on mobile apps in Vietnam (State of mobile apps Q2/2015) provides quarterly operational benchmarks for developers and game publishers. The 23-slide study combines telemetry from Appota's distribution platform (reaching 17.5 million users in Vietnam, up from 13 million in Q1 2015) with datasets from IDC, Apple, Google, VNG, Viber, Mobile Game Asia 2015, Facebook Ads, GfK, and Tech in Asia.

Readers following our Gaming coverage can compare these findings with the State of Mobile Apps in Vietnam Q1 2015 Report to track sequential shifts. Chapter 1 (slides 4–6) reviews three-year global operating system share trends and contrasts version upgrade velocity between Apple's iOS 8 and Google's Android Lollipop.

According to IDC Smartphone OS Market Share, Q1/2015 data cited on slide 4, global smartphone OS distribution from Q1 2012 through Q1 2015 remained led by Android and iOS:

Android leads with a 78% share: Android's global share rose from roughly 59% in Q1 2012 to ~75% in Q1 2013 and ~81% in Q1 2014 before adjusting to 78% in Q1 2015.
iOS holds an 18.3% share: While down slightly from the Q4 2014 holiday peak and below its ~23% mark in Q1 2012, Q1 2015 iOS share (18.3%) stood above its Q1 2013 (~17%) and Q1 2014 (~15.2%) levels.
Windows Phone rebounds slightly to 2.7%: Windows Phone edged up YoY from 2.5% to 2.7%, leaving open whether Microsoft could expand its ecosystem with Windows 10. All other platforms (Others) fell from ~9.5% in Q1 2012 to 1.0% in Q1 2015.

Operating System / Version	Q1 2012	Q1 2013	Q1 2014	Q1 2015 (Apr–May 2015)	Slide Source
Android (Global OS share)	~59.0%	~75.0%	~81.0%	78.0%	IDC (slide 4)

Others (Global OS share)	~9.5%	~1.5%	~1.2%	1.0%	IDC (slide 4)
Global iOS version split	—	—	—	iOS 8: 81% · iOS 7: 17% · Earlier: 2%	Apple, Apr 27, 2015 (slide 5)
Global Android version split	—	—	—	KitKat: 39.8% · JB (labeled ICS): 39.2% · Lollipop: 9.7% · Earlier: 6.0%	Google, May 2015 (slide 6)

Global Upgrade Contrast: iOS 8 Reaches 81% Adoption While Android Lollipop Stands at 9.7%

Slides 5 and 6 contrast global OS version adoption across Apple and Google in April and May 2015:

iOS 8 reaches 81% of eligible devices (slide 5): Per Apple's App Store visitation stats on April 27, 2015, 81% of eligible iOS devices ran iOS 8 (up 2 percentage points from Apple's prior release), with iOS 7 at 17% and Earlier versions at 2%. Growth was supported by iOS 8.3, the Apple Watch, and developer testing of iOS 8.4 with its redesigned Music app.
Android KitKat (39.8%) and Jelly Bean (39.2%) dominate as Lollipop hits 9.7% (slide 6): Per Google's May 2015 stats, Android's top two builds remained KitKat (39.8%) and Jelly Bean (note: the slide 6 chart mislabels the 39.2% Jelly Bean slice as ICS 39.2%, alongside Kitkat 39.8%, Lollipop 9.7%, and Earlier 6.0%). Released two months after iOS 8, Lollipop initially reached 5.4% of devices before Android 5.0 and 5.1 combined reached 9.7% in May 2015.

3D MMORPG Thế Giới Hoàn Mỹ enters both Top 10s: Powered by iPhone 5/6 and 2GB RAM budget Android phones, Thế Giới Hoàn Mỹ ranked #5 on iOS and #10 on Android.
Games claim 70% of slots while TV and music streaming take 30%: Alongside MobiTivi and NCT, Zing MP3 joined both Top 10 charts (#9 on iOS, #4 on Android).

How Did Appota's 17.5-Million-User Ecosystem and Adsota Expand in Q2 2015?

Slide 2 and Chapter 4 (Update from Appota, slides 22–23) outline Appota's ecosystem, which reached 17.5 million users in Vietnam across three service pillars (slide 2):

Distribution & Publishing: Appota Distribution Platform, Appdaily Affiliate Network, and Payota Payment Platform.
Advertising: GameHub.vn Media News and Adsota Mobile Ads Network.
Social Network: onClan social network for mobile gamers.

On slide 22, Appota announced three Q2 2015 milestones:

Upcoming launch of Adsota: A mobile ads network specialized in driving installs and maximizing game/app monetization via diverse ad formats and intelligent targeting algorithms.
Two game titles released in Thailand: Appota launched Top 12 and Ai My Nhan Mobile (Ải Mỹ Nhân Mobile) in the Thailand market.
YouTube Silver Play Button award: A mobile game review channel on Appota's distribution network (GameHub.vn) received YouTube's Silver Play Button award as Vietnam's premier mobile game review channel.

Four Actionable Priorities for Mobile App and Game Publishers in Vietnam

From Appota's Q2 2015 telemetry, product and publishing teams can execute four priorities:

Ship 3D Mid-Core Titles Targeting $150–$250 Android Phones and iPhone 5/6: With Asus/Oppo 2GB RAM phones supporting 3D games and iPhone 5 (~30%) plus iPhone 6/6+ (12%) exceeding 42% of iPhone users, studios can scale 3D titles while maintaining QA on Android 4.4 KitKat (>50%) and Samsung devices (32%).
Optimize Installers for Wi-Fi (79% Traffic) and Gameplay for 3G (1.9 Mbps): Because 3G costs $3–$5/GB at 1.9 Mbps versus 17.3 Mbps on $10/month unlimited Wi-Fi, apps should route large asset downloads over Wi-Fi and compress live gameplay packets for 3G.
Pair Zalo In-App Ads (30M Users) and Facebook Ads (22M Sample) With Adsota: User acquisition teams should combine Zalo in-app ads and Facebook Ads (61% Android, 31% iOS) with Adsota, Appdaily, and GameHub.vn video reviews.
Support Carrier Billing (AppMarket, Payota) and Regional Exports: Weekly carrier subscriptions like VND 15,000/week AppMarket and Payota complement bank cards and e-wallets under a structured payment gateway integration checklist, while top titles can expand into Thailand and South Korea.

The deck comprises an ecosystem overview and methodology introduction (slides 2–3) followed by four chapters: (1) Global OS breakdown (slides 4–6); (2) Vietnam mobile news (slides 7–11); (3) Mobile apps in Vietnam, covering smartphone penetration, Wi-Fi vs. 3G connectivity, iOS and Android breakdowns, and download leaderboards (slides 12–21); and (4) Update from Appota (slides 22–23). External and partner data sources include IDC (Q1 2012–Q1 2015 global smartphone OS market share on slide 4), Apple (global iOS 8 adoption measured by App Store visits on April 27, 2015 on slide 5), Google (global Android version distribution in May 2015 on slide 6), VNG and Viber (Vietnam OTT messaging user counts on slide 9), Mobile Game Asia 2015 and Facebook Ads (active 3G accounts, mobile internet users, smartphone users, and OS breakdown across a 22-million-user sample on slide 12), and GfK, Tech in Asia, and Appota's platform (Wi-Fi vs. 3G traffic split, average speed, and data pricing on slide 13). Data-hygiene notes verified against the 23 original slides: (1) On slide 4, the text commentary states iOS market share for Q1 2015 declined slightly to 18.3% (reflecting a sequential dip from the Q4 2014 holiday quarter or a multi-year decline from ~23% in Q1 2012), whereas on the plotted Q1 2012–Q1 2015 line chart iOS rises year-over-year from ~15.2% in Q1 2014 to 18.3% in Q1 2015; (2) On slide 6, the left-hand narrative explicitly states that Android's two most popular builds remained KitKat (39.8%) and Jelly Bean, but the donut chart mislabels the 39.2% Jelly Bean slice as 'ICS 39.2%', and the four labeled slices (39.8% + 39.2% + 9.7% + 6.0%) sum to 94.7% (omitting the 5.3% true Ice Cream Sandwich slice from Google's May 2015 dashboard); (3) On slide 12, within the 22-million-user Facebook Ads smartphone sample, 13.5 million Android users (61.36%, rounded to 61%) and 6.9 million iOS users (31.36%, rounded to 31%) sum to 20.4 million, leaving 1.6 million Windows Phone users (7.27%, rounded to 8% on the pie chart so the slices total 100%); (4) On slides 14, 15, and 16, as in the Q1 2015 edition, the iPhone model lines and the grouped version bars for iOS (iPhone and iPad) and Android (Phone and Tablet) are normalized across 100% of total devices on each OS; (5) On slide 19, the quarterly download index climbs from 132% in Q1 2015 to 140% in Q2 2015 against the Q1 2014 = 100% baseline, meaning the '8% Growth compared to previous quarter' callout represents an 8-percentage-point increase on the index (+6.06% relative QoQ growth, and +40% above Q1 2014).
