NEW DELHI, Sept 18 (Reuters) - Google abused the dominant position of its Android operating system in India, using its "huge financial muscle" to illegally hurt competitors, the country"s antitrust authority found in a report on its two-year probe seen by Reuters. Alphabet Inc"s (GOOGL.O) Google reduced "the ability and incentive of device manufacturers to develop and sell devices operating on alternative versions of Android," says the June report by the Competition Commission of India"s (CCI) investigations unit. The U.S. tech giant told Reuters in a statement it looks forward to working with the CCI to "demonstrate how Android has led to more competition and innovation, not less." Google has not received the investigation report, a person with direct knowledge of the situation told Reuters. The CCI did not respond to a request for comment on the report. Senior CCI members will review the report and give Google another chance to defend itself, before issuing a final order, which could include penalties, said another person familiar with the case. Google would be able to appeal any order in India"s courts. Its findings are the latest antitrust setback for Google in India, where it faces several probes in the payments app and smart television markets. The company has been investigated in Europe, the United States and elsewhere. This week, South Korea"s antitrust regulator fined Google $180 million for blocking customised versions of Android. "VAGUE, BIASED AND ARBITRARY" Google submitted at least 24 responses during the probe, defending itself and arguing it was not hurting competition, the report says. Microsoft Corp (MSFT.O), Amazon.com Inc (AMZN.O), Apple Inc (AAPL.O), as well as smartphone makers like Samsung and Xiaomi, were among 62 entities that responded to CCI questions during its Google investigation, the report says. Android powers 98% of India"s 520 million smartphones, according to Counterpoint Research. When the CCI ordered the probe in 2019, it said Google appeared to have leveraged its dominance to reduce device makers" ability to opt for alternate versions of its mobile operating system and force them to pre-install Google apps. The 750-page report finds the mandatory pre-installation of apps "amounts to imposition of unfair condition on the device manufacturers" in violation of India"s competition law, while the company leveraged the position of its Play Store app store to protect its dominance. Play Store policies were "one-sided, ambiguous, vague, biased and arbitrary", while Android has been "enjoying its dominant position" in licensable operating systems for smartphones and tablets since 2011, the report says. The probe was triggered in 2019 after two Indian junior antitrust research associates and a law student filed a complaint, Reuters reported. India remains a key growth market for Google. It said last year it would spend $10 billion in the country over five to seven years through equity investments and tie-ups, its biggest commitment to a key growth market.
