While there has been rapid deployment of 4G services in India in the last year, the telecom operators have held MediaTek responsible for the deteriorating service offered by the operators.
Cellular Operators’ Association of India (COAI) has alleged that there is a technical glitch with dual SIM 4G smartphones powered by MediaTek processors. The body claimed that the flow of data in the primary 4G SIM slot was hampered when a 4G LTE-only SIM was placed in the second slot, meant for 2G SIM.
COAI has already approached the TRAI to seek the regulators intervention in resolving the glitch which is apparently affecting the quality of services provided by the telecom operators. The body proposed a four weeks’ time period to allow smartphone makers to release an update to resolve the issue or demanded withdrawal of such devices from the market.
COAI has identified eight handset including Lenovo A7000 and K4 Note, Xiaomi Redmi 3S and Note 3, Motorola Moto G4, Oppo A35, Micromax Canvas E451 and Intex Aqua Craze which suffer from the technical glitch.
Speaking about the issue, Rajan S Mathews, Director General, COAI, said, “It was observed that placing a SIM (which has only 4G LTE capability) in the number 2 slot (2G-only) significantly deteriorates the throughput of any other operator’s 4G SIM present in the main slot, by as much as 40 per cent.”
