Change ‘Preferred Network Mode’
Your smartphone has several settings that you could program to get satisfying results. One such setting is preferred network mode wherein you select if you want the system to detect only 4G networks or allow it to scan and register for lower bands too i.e. 3G and 2G. The idea behind this is that 4G is comparatively newer than 3G and 2G which means, the older networks are far more penetrative in every nook and corner of the region, city, country, etc. If 4G network for your phone is not available, the phone could search for lower bands which means you can at least call and message and browse although slightly slow. You can visit Settings >> SIM & Networks >> Preferred Network.
Alter ‘Network Selection Mode’
Next settings are available of network selection mode which is either automatic or manual. By default, it will be set at automatic where the system will automatically search and register for a compatible network while a manual mode would require manually searching and registering to a selected network. This is handy if there’s a weak network in your home network or you are traveling.
Purge all types of cache
Unless you are living under a rock, you would know that accumulation of cache files is not healthy for a system as it will make it sluggish and a pertinent character attracting bugs and viruses and whatnot. There are a number of reasons why we shouldn’t keep cache files in our devices and this weak signal or lost network issue is one of them so you need to clear it right away.
Note that there are a number of different cache files such as storage cache which you can access and delete via Settings >> Storage >> Cache Memory. Next type of cache files are app caches that can be found via Settings >> Apps >> Downloaded >> ‘Click on an app’ >> ‘Clear Cache’ and ‘Clear Data’. The third is cache partition for which, you need to retreat to the recovery mode where you can wipe cache partition and a reference to the said procedure is mentioned below.
Update all apps/firmware
You can update all the apps and the Android firmware to resolve any update-related issue which is a thing. For this, you need to open Google Play Store and navigate to ‘My apps and games’ section where you’ll get options to either update apps individually or together or turn on ‘auto-update’ for the same. Meanwhile, you can visit Settings >> About Device >> Software Updates to check out for available updates.
Pull a factory reset
If nothing else works, try pulling a factory reset on your device and it must work just fine or you can report the issue to a service center. You’ll need to press power + volume up button together when the device is turned Off so that you can use volume rockers to scroll and power button to select an option. You need to select ‘wipe data/factory reset’ and that must do the job.
Buy an external network booster
Call it scheduled place or someplace where the network is literally weak, here you can install an external network booster that will fix the problem just like that. Network booster act as a mini cell tower where it intercepts signals from a cell tower amplifies it and broadcast it through the house or office as per its limitation. This allows users to make calls, send and received messages, and more while sitting in a place where the network is not expected to be available such as a washroom, or a room within a room or so.
This is because in case if the root of the problem is via SIM card or the telecom towers around your house or office, the telecom carrier will be able to help resolve these issues. Since there is no third-party telecom carrier center, you will have to visit a gallery or say carrier’s outlet or office in your locality to get a resolution of the same.
Visit nearby smartphone service center
Little do we know that weak signal or lost network issue could be a result of hardware damage or failure as well but let’s include an unsolved software issue as well. Here, the smartphone service center will be able to help fix the problem by scrutinizing it and fixing it that requires either flash, replacement, or repair, etc and that will be charged if not covered by warranty.
