What prevents my samsung galaxy grand duos from upgrading to latest android version? I have been trying to upgrade my galaxy grand duos from android 4.2.1 to android 4.4.1 (Kitkat) version, but whenever I try upgrading the phone, the phone always hangs that I have to flash the phone before I can use it.
The Samsung Galaxy Grand I9082 is a discontinued 3G Smartphone operating on 2G and 3G network bands using GSM and HSPA technologies. It was unveiled to the public on December 2012 and released on January 2013 measuring 143.5 x 76.9 x 9.6 millimeters and weighing 162 grams. It is dual SIM and built with plastic body.
It has TFT capacitive touchscreen display with 16M colors at 480 x 800 pixels screen resolution with TouchWiz UI. It runs on Android 4.1.2 Jelly Bean upgradable to Android 4.2.2 Jelly Bean powered by 1.2 GHz Dual-Core Cortex-A9 processor and Broadcom VideoCore IV GPU. It supports microSD expandable up to 64 GB. It runs on 1 GB RAM with 8 GB internal storage.
The primary camera supports 8 megapixels featuring f/2.7, AF, and LED flash. It supports 1080p video recording at 30 fps with stereo sound rec. The secondary camera supports 2 megapixels.
It has 3.5-millimeter jack featuring active noise cancellation with dedicated mic; Wi-Fi 802.11 a/b/g/n with dual-band, hotspot, and DLNA support; Bluetooth 4.0 with A2DP, EDR, and LE support; GPS with A-GPS and GLONASS support; stereo FM radio with RDS support; and microUSB 2.0. It has built-in accelerometer, gyro, proximity, and compass sensors.
It runs on removable Li-Ion 2100 mAh battery with standby time up to 440 hours and talk time up to 10 hours 10 minutes. It is available in black and white colors. Now, if you want to upgrade your phone from Android 4.2.1 Jelly Bean to Android 4.4.1 KitKat, I don’t think it’s possible because your phone model is not supported.
The highest version you can upgrade to is Android 4.2.2 Jelly Bean and you cannot go any higher than that. If you want a much higher version like KitKat, change your phone and buy a new one.
